By Darian Macey, March 31 2025
The Australian Defence Estate is entering a new era of project delivery with the launch of the Defence Infrastructure Panel – Major Construction 2025–2030 (DIP-MC). Announced by Defence’s Security and Estate Group (SEG) as the first panel of its kind, the DIP-MC establishes a standing offer arrangement for delivering large-scale construction and capital facilities projects. This panel is specifically scoped for major projects valued at $200 million or more (exclusive of GST), representing a significant shift in how Defence will procure its biggest infrastructure works. Not only will the panel service the Department of Defence, but it’s also open for use by other Commonwealth agencies, broadening its strategic importance across government.
As a standing offer panel, DIP-MC pre-qualifies a group of contractors capable of delivering complex, high-value projects. It is important to note upfront that being on the panel does not guarantee any work. The Commonwealth has explicitly reserved the right to procure outside the panel and makes no promises about project volume. However, inclusion on DIP-MC offers strategic value: panellists
- gain a competitive edge in accessing upcoming mega projects,
- enjoy streamlined tender processes, and
- can build closer working relationships with Defence.
In short, DIP-MC is a game-changer – it promises faster procurement, fosters industry collaboration, and sets a new benchmark for delivering Defence infrastructure at scale.
Why DIP-MC Matters for Defence and Industry
The creation of DIP-MC is a milestone for Defence procurement. Traditionally, capital works of this magnitude were tendered through standalone processes; now, with an ongoing panel, Defence aims to accelerate project delivery and leverage long-term partnerships. This panel approach recognises that investing in a stable pool of contractors can bring efficiencies for both Defence and industry. For Defence, it means quicker mobilisation of pre-qualified builders, reduced tender overheads, and more consistent project outcomes. For panellists, it means clearer visibility of the project pipeline and reduced costs in bidding (thanks to standardised documents and pre-qualification). It’s a win-win that aligns with the National Defence Strategy’s push for readiness and enhanced capability delivery.
Another key significance of DIP-MC is its centralised administration by SEG, ensuring strong governance. SEG will manage the panel, monitor performance, and maintain compliance with Defence policies (security, safety, indigenous participation, etc.). Because DIP-MC can be used by other agencies, it also represents a whole-of-government opportunity – other departments with big construction needs (over $200M) can tap into this Defence panel. This could lead to more uniform contracting standards across government and increased workload for panel members beyond Defence projects. For businesses and consultants in the Defence Estate sector, understanding DIP-MC is crucial: it will shape the market for major works over the next five years.
Importantly, while panel inclusion is not a guarantee of contracts, it certainly positions companies to win work that might not otherwise be accessible. In effect, DIP-MC is a club of 18 pre-approved builders who will get the first (and often only) shot at projects above $200M. Being in that club is a significant competitive advantage. Even so, non-panel firms aren’t completely shut out – Defence reserves the option to go outside if needed, and panel members can team with other contractors or specialists. Overall, DIP-MC represents a strategic shift to a more collaborative, long-term procurement model for mega projects, one that both panel contractors and their partners need to navigate adeptly.
Who’s on the Panel?
After a rigorous selection process, Defence has appointed 18 companies to the DIP-MC panel. These organisations represent a who’s who of major construction, each with proven capability to deliver complex projects nationwide. The panellists (and their panel entities) are:
Overview and Ownership: Acciona Construction Australia is the local arm of Spanish multinational Acciona S.A., a global leader in infrastructure and renewable projects. It entered the Australian market in 2002 and grew significantly through major transport and energy contracts. The company is headquartered in Sydney and employs hundreds locally, backed by Acciona’s 30,000-strong global workforce. Acciona is foreign-owned but operates as an Australian incorporated entity. It has a reputation for sustainable construction practices and innovation, aligning with Acciona’s global “Business as unusual” ethos ([1]). Acciona Australia expanded its capabilities by acquiring engineering businesses and now competes as a Tier-1 builder in large projects.
Experience in Defence Infrastructure: Acciona is a new entrant to Defence infrastructure delivery, with limited direct project history in the Australian Defence estate. However, it brings extensive experience managing complex, large-scale civil works (for example, Acciona is delivering Sydney Metro West’s $1.96 billion tunnelling package ([1]). This track record in executing $200m+ projects positions Acciona to handle major Defence contracts. The company has been building its Defence credentials by recruiting experienced project managers and bidding for Defence panels. While it does not yet boast notable ADF base projects, Acciona’s portfolio of airports, roads and rail works demonstrates relevant capabilities (logistics, heavy infrastructure) that are transferable to Defence facilities. Its approach emphasizes safety, quality and environmental management – all crucial for secure Defence sites.
Points of Difference / Strategic Fit for DIP-MC: Acciona offers fresh competition and global expertise to the DIP-MC panel. It is likely to leverage its Spanish parent’s experience on international defence and civil works to introduce innovative construction methodologies. The firm is known for sustainability and has pledged to deliver low-carbon infrastructure, aligning with Defence’s ESG goals. Acciona’s lack of legacy ties in the Defence sector means it brings a “clean slate” and potentially more flexible, value-for-money solutions. It has reportedly joined the Defence Industry Security Program (DISP) to ensure compliance with security requirements, and it is building internal capability for handling sensitive projects. Its strategic fit lies in its ability to deliver mega-projects in remote or challenging environments – a common scenario for large Defence bases – and its commitment to Indigenous engagement and local industry content, which will help meet Commonwealth Indigenous Procurement Policy targets. Acciona’s entry into DIP-MC signals Defence’s intent to broaden its contractor base with internationally proven builders. (Sources: Company reports; Sydney Metro West contract details ([1]))
Overview and Ownership: BMD Constructions is a proudly Australian-owned civil construction company, part of the BMD Group founded in 1979. It remains family-owned (by founder Mick Power) and is one of Australia’s largest privately held contractors. Headquartered in Brisbane, BMD employs over 1,700 people nationally. The company specializes in civil infrastructure (roads, airfields, land development) and has a strong regional presence across Queensland, the Northern Territory and beyond. Being Australian-owned (“sovereign-owned”), BMD emphasizes local workforce development and long-term client relationships. It has grown into a Tier-2/Tier-1 contractor with an annual turnover in the billions, while retaining a flat management structure and a reputation for partnering with local SMEs. BMD Group was ranked #26 on Australian Defence Magazine’s Top 40 Defence Contractors list for 2024 ([2]), reflecting its increasing role in Defence projects.
Experience in Defence Infrastructure: BMD has an extensive track record delivering Defence estate works, particularly in airfield and base infrastructure upgrades. It is experienced in working within live bases under Security and Estate Group (SEG) programs. BMD has delivered RAAF Base Edinburgh’s Stage 2 civil works (upgrading ordnance loading aprons and base services) and RAAF Amberley’s aircraft pavements for C-17 operations ([3]). The company is well-versed in airfield projects – for example, it has been involved in the National Airfields Maintenance Program, providing runway and lighting upgrades at multiple bases. BMD’s current Defence portfolio spans major bases across Australia, including airfield infrastructure upgrades at RAAF Base Tindal (NT), RAAF Base Edinburgh (SA), RAAF Base Richmond (NSW) and HMAS Albatross (NSW) ([2]). These projects often involve complex staging to keep base operations running, a challenge BMD has managed successfully. BMD also contributed to Defence housing and facilities construction through the Single LEAP program, building new live-in accommodation at Army and RAAF bases ([4]). Delivery models range from head contractor on traditional design-bid-build jobs to managing contractor for civil works packages. BMD is known for self-performing critical works (earthworks, pavements), which provides greater control over safety, schedule and quality on Defence sites.
Points of Difference / Strategic Fit for DIP-MC: As a mid-tier Australian contractor, BMD offers deep regional knowledge and self-performance capability, making it valuable for Defence projects in remote or regional locations. It has proven ability to deliver in “live” environments – working within active air bases without disrupting operations ([5]). BMD’s strong Indigenous engagement is noteworthy: it actively involves Indigenous businesses and employees, aligning with Defence’s Indigenous Procurement Policy (IPP) goals. For example, on recent base projects BMD exceeded Indigenous participation targets as part of its commitment to local communities. The company’s background in civil infrastructure means it can tackle projects requiring significant earthworks, runways, and services – key components of many $200m+ Defence facilities upgrades. BMD also prides itself on a collaborative approach and long-term partnerships (it often works with Defence base services contractors and regional subcontractors), which helps in managing stakeholder expectations like base command or Defence’s project managers. Under DIP-MC, BMD is a good strategic fit for projects emphasizing Australian industry content and legacy infrastructure renewal. Its understanding of Commonwealth procurement (e.g. BMD’s National Head of Defence notes the company’s experience in complex base environments ([2])) and its “One BMD” integrated service model allow it to offer Defence a reliable, agile delivery partner for major capital works.
Overview and Ownership: Bouygues Construction Australia is the local subsidiary of Bouygues S.A., a French engineering and construction giant. In Australia, Bouygues expanded its building capabilities by acquiring AW Edwards in 2018, a well-established Sydney-based contractor. AW Edwards (founded 1921) operates as a division of Bouygues and brings nearly a century of local building experience. The combined entity is foreign-owned (by Bouygues Group) but deeply embedded in Australia’s construction industry. Bouygues Australia is headquartered in North Sydney, with AW Edwards maintaining its brand on projects in NSW. Together they employ around 600 staff in Australia. AW Edwards has a long heritage – notably, it delivered defence projects leading up to WWII (from 1934 onwards) including wartime facilities ([6]). As part of Bouygues Construction, the company also has access to international expertise in complex building, civil and marine works (Bouygues built tunnels, bridges and defence facilities globally). Bouygues/AW Edwards is thus a blend of local knowledge and global resources.
Experience in Defence Infrastructure: AW Edwards has completed various Australian Government projects over the decades, though recent direct Defence projects have been modest. Historically, AW Edwards built defence infrastructure such as armament factories and barracks during WWII ([6]), establishing a legacy of working with the Commonwealth. In the modern era, AW Edwards has focused on commercial, health, and education buildings, but some of these skills translate to Defence needs (e.g. secure facilities and complex services integration). Under Bouygues, the company has begun pursuing larger infrastructure projects which could include Defence bases. Bouygues Construction Australia itself delivered major civil works (e.g. NorthConnex motorway tunnel and Sydney Metro stations), demonstrating capability in large-scale project management and technical innovation that could be applied to Defence environments. While the Bouygues/AW Edwards joint capabilities have not yet been showcased on a marquee Defence base redevelopment, they have worked on projects with similar complexity: high-security data centres, large hospitals, and critical infrastructure requiring strict quality and safety standards. Additionally, Bouygues has international defence experience (for example, constructing French military facilities and NATO headquarters), which can inform its Australian projects. The company is pre-qualified on Defence infrastructure panels (including previous Estate Works Programs), indicating it meets Defence’s requirements for security and performance. Notably, AW Edwards is known for precise delivery of complex building works – a relevant skill for things like specialised training facilities or command buildings.
Points of Difference / Strategic Fit for DIP-MC: Bouygues Construction Australia (with AW Edwards) brings a unique combination of European technical expertise and local building heritage. This can translate into innovative construction techniques for Defence – for instance, advanced precast concrete methods or proven design solutions from overseas military projects. The company’s strong engineering background means it can tackle design-and-construct or ECI (Early Contractor Involvement) delivery models preferred in many Defence projects. Bouygues also offers in-house expertise in marine works, which is pertinent for projects involving wharves or waterfront facilities (e.g. naval base upgrades). As a multinational, Bouygues has stringent corporate governance and sustainability programs, aligning well with Defence’s growing emphasis on ESG. It is likely a DISP member (ensuring security-cleared personnel and systems), given its work on sensitive government facilities. For the DIP-MC panel, Bouygues/AW Edwards provides a trusted building contractor for complex vertical infrastructure – such as headquarters, hangars, or training centres – and can scale up with Bouygues’ global resources if needed. Its strategic fit includes a focus on innovation (Bouygues is known for R&D in construction) and a demonstrated commitment to local industry: AW Edwards regularly engages NSW subcontractors and has an apprenticeship program, supporting the Australian Skills Guarantee objectives. In summary, Bouygues Construction Australia (with AW Edwards) adds depth to the panel with its combination of local reliability and international capability, suitable for delivering large, complex Defence projects in Australia.
Overview and Ownership: Built is a leading Australian-owned construction company known for high-quality building projects. Founded in 1998 and headquartered in Sydney, Built has grown from a fit-out specialist into a national Tier-1 contractor with offices in all major capitals. The company remains privately owned (by founder Ross Walker and key executives) and has about 1000 employees across Australia. Built prides itself on a collaborative culture and “builder’s mindset”, often tackling complex refurbishments and new builds in commercial, retail, and institutional sectors. Under the Built brand, it operates regionally with subsidiaries like Built NSW, Built Victoria, etc., including a dedicated Queensland arm (see separate profile for Built Qld). Built has established a Defence & Government division, and notably it holds Defence Industry Security Program (DISP) membership, indicating its systems and staff are cleared for sensitive projects ([7]). According to the company, Built has delivered 20+ Defence projects nationwide valued at over $250 million in total ([7]), reflecting a solid portfolio in this sector.
Experience in Defence Infrastructure: Built’s experience in Defence infrastructure spans mostly medium-sized projects and refurbishment works. It has completed works on bases such as upgrades to offices, training facilities, and heritage restorations for Defence. For example, Built was involved in the refurbishment of the historic Victoria Barracks in Sydney (a complex heritage Defence project) and delivered facilities for the Defence Science & Technology Group. Built also has been working on defence-industrial projects; it is the contractor for Hanwha’s Armoured Vehicle Centre of Excellence in Victoria (a major new military manufacturing facility) ([8]), which it approached with advanced digital engineering techniques. Built’s Defence projects often come under Estate Works Program panels or as head contractor for specific base works packages – these include magazine (ammunition storage) upgrades, simulations facilities, and security enhancements on bases. The company emphasizes technology in delivery; Built has championed digital design and BIM, which has proven valuable in Defence projects where “build it digitally first” can de-risk complex construction ([9]). While Built has not yet been prime on a $200m+ base redevelopment, it has partnered on larger projects (for instance, working alongside other Tier-1 builders on elements of Defence headquarters buildings). Its track record shows consistent on-time, on-budget delivery for Defence Estate projects, which has built trust with Defence as a client.
Points of Difference / Strategic Fit for DIP-MC: Built’s key strength is its agility and innovative construction methods in delivering complex builds to high quality standards. This is a strategic asset for Defence, which often requires bespoke facilities (like laboratories, communication centres, or simulation hubs) with strict specifications. Built is known for leveraging digital engineering – something even Defence has recognized as game-changing for infrastructure ([9]). This reduces risk and improves safety (important for live base environments). Another point of difference is Built’s experience in heritage and refurbishment; many Defence bases have aging infrastructure requiring upgrade within operational constraints, a scenario where Built excels. Built also brings strong compliance with Commonwealth procurement policies: as a DISP member it upholds security protocols, and it has a Reconciliation Action Plan supporting Indigenous engagement (aligning with IPP). The company has a relatively flat structure and a client-focused approach, enabling faster decision-making and flexibility in contracts – useful for the panel’s fast-track projects. Its “digital first” ethos and strategic Defence advisors (including former Defence personnel) give it insight into Defence’s expectations ([9]). Overall, Built offers the panel a high-performing Australian contractor capable of delivering complex Defence facilities with innovation, making it a strong fit for projects requiring a fresh approach and meticulous execution.
Overview and Ownership: Built Qld Pty Limited is the Queensland division of Built, operating as a separate legal entity but part of the national Built group. It is Australian-owned, mirroring the ownership of the parent company (privately held by senior management). Built Qld is headquartered in Brisbane and focuses on projects in Queensland and northern Australia. The company leverages the same resources and systems as Built Pty Ltd, ensuring consistency in quality and safety. Built Qld’s formation allows it to hold the necessary state-specific builder licences and meet Queensland Government procurement requirements. It has established itself in the Qld market through commercial developments, refurbishments, and government projects. The entity is relatively mid-sized in Queensland but can draw on Built’s national workforce for larger jobs. Built Qld is also DISP accredited via the Built group, reflecting its preparedness for secure Defence works. Its regional focus includes Brisbane, Townsville, and Darwin (the latter serviced in partnership with Built’s national team), aligning with key Defence locations in the north.
Experience in Defence Infrastructure: Built Qld has been involved in Defence-related projects mainly through fit-outs and minor capital works on bases. For instance, the company delivered upgrades at Gallipoli Barracks in Enoggera, Brisbane – refurbishing offices and amenities for Army units stationed there. It has also undertaken works at RAAF Base Amberley, such as renovating training classrooms and simulators, and at Townsville’s Lavarack Barracks (e.g. a vehicle maintenance facility upgrade). These projects, while not headline-grabbing, have given Built Qld familiarity with Defence’s project processes and base access protocols. Moreover, Built Qld benefits from the broader Built portfolio; for example, it provided support on the Hanwha Armoured Vehicle Centre project (though in Victoria, the knowledge is shared internally) and has staff experienced in large Defence projects from other states. In Queensland, Built Qld has positioned itself for upcoming Defence opportunities: it has participated in the Australia-Singapore Military Training Initiative by bidding on packages at the new Greenvale Training Area, and has engaged with Defence Housing Australia on housing developments for military personnel. While it may not yet have a single $200m Defence build completed, Built Qld has successfully delivered complex government facilities (courthouses, research labs) which are comparable in complexity and security to Defence requirements. This includes heavy involvement in digital modelling and stakeholder coordination – skills that are directly relevant to managing Defence infrastructure jobs.
Points of Difference / Strategic Fit for DIP-MC: Built Qld offers a local presence in Queensland with the backing of a national Tier-1 contractor. Its understanding of the Queensland construction market – local subcontractors, suppliers and logistics – is a strength for Defence projects in the region (which often aim for high local industry content). This is well-aligned with the Commonwealth’s Australian Industry Capability and Skills Guarantee policies, as Built Qld routinely engages local trades and apprentices on its sites. The company’s relatively smaller size in Qld means it can be more hands-on and responsive than some larger competitors, an advantage in managing on-base works where flexibility is key. Built Qld is also at the forefront of digital construction in the state; it has used advanced BIM and even virtual reality to plan projects, reducing rework and enhancing safety – an approach that dovetails with Defence’s push for innovation in infrastructure. Furthermore, Built Qld has a track record of working harmoniously with Defence’s consulting firms (PMCA and base managers), often earning commendations for minimal disruption and cooperative planning. As part of DIP-MC, Built Qld is a good fit especially for projects in northern Australia that require both local knowledge and sophisticated delivery methods. Its commitment to Defence as a client is evidenced by investment in a strategic Defence advisory board and training its staff in Defence cultural awareness. All these factors make Built Qld an agile and capable panel member for delivering Queensland-based Defence projects up to and exceeding $200 million in value.
Overview and Ownership: CPB Contractors is Australia’s largest construction contractor and a core part of the CIMIC Group (formerly Leighton Holdings). It is Australian-incorporated but majority-owned by the Spanish-headquartered ACS Group (through Germany’s Hochtief). CPB was formed from the merger of Leighton Contractors and Thiess’s construction business and has a lineage dating back to 1949 in Australian infrastructure. Headquartered in Sydney, CPB has a nationwide presence and a workforce in the many thousands. It is a true Tier-1 builder, delivering megaprojects across all sectors. Within CIMIC, CPB focuses on building and civil construction (while sister companies cover mining and services). CPB has a dedicated Defence and national security portfolio and is an approved Defence Recognised Supplier. The company’s scale and financial strength allow it to tackle multiple $1bn+ projects simultaneously. CPB’s corporate affiliation with CIMIC provides access to global best practices and financial backing, but it operates with largely Australian management for domestic projects. It has long-standing relationships with the Department of Defence as a contractor on capital facilities programs since the 1980s (when known as Leighton).
Experience in Defence Infrastructure: CPB Contractors (and predecessor Leighton Contractors) has an extensive and storied track record in Defence infrastructure. It has delivered some of the largest Defence construction projects in recent history. Notably, CPB was appointed the Managing Contractor for the ASMTI Greenvale Training Area in North Queensland, developing a brand new $800m Army training range ([10]). CPB has proven expertise in airbase projects: it delivered significant upgrades at RAAF Base Amberley (Queensland’s super base for the Air Force), RAAF Base Williamtown Redevelopment (NSW), and RAAF Base Pearce (WA) for runway and pavement refurbishments ([5]). In 2023, CPB was selected for Early Contractor Involvement on RAAF Base Curtin and Learmonth runway upgrades ([5]), drawing on its prior successful delivery of works at Pearce, Amberley and Williamtown that “ensured normal operations continue without disruption” ([5]). CPB has also delivered education projects – for example, new facilities for RAAF Base Wagga, Army Recruit Training Centre at Blamey Barracks (Kapooka) and Albury Woodonga Military Area (AWMA) due for completion in 2031. CPB is delivering the North Queensland Mid-Term Refresh Program (NQMTR), which includes estate maintenance and upgrades at TFTA, such as new and upgraded engineering services and building refurbishments. Recently, CPB secured the Army Aviation Program of Works in Townsville (~$370m) to build an aviation centre of excellence relocating regiments to RAAF Townsville ([12]). This breadth of experience – from barracks and training facilities to runways, and specialist research labs – makes CPB arguably one of the most experienced major contractor in the Defence estate domain. CPB’s familiarity with Defence stakeholders (Infrastructure Division, CASG, base command) is high; it has partnered with all key Defence PMCA firms and has frameworks for engaging base-level user groups during construction.
Points of Difference / Strategic Fit for DIP-MC: CPB’s strength lies in its capacity and depth of resources – it can mobilise large teams and equipment to any location in Australia, a critical factor for $200m+ projects often in remote Defence sites. It has demonstrated capability acknowledged by Defence; CPB is frequently praised for understanding and meeting operational and security requirements on base ([12]). For example, CPB has developed methods to work airside on runways without compromising flight schedules, and to harden facilities to Defence security standards. Its project management systems are robust, honed by decades of delivering for Defence. Under DIP-MC, CPB offers a “safe pair of hands” for the most complex projects or tight timeframes. It is also at the forefront of compliance with procurement-connected policies: CPB has established Indigenous Participation Plans on its Defence projects and consistently meets or exceeds targets for local industry involvement. (On one recent northern base project, CPB committed to 70% local content and delivered via local SMEs). The company’s scale also allows implementing the Australian Skills Guarantee by onboarding apprentices and trainees on big Defence jobs – something CPB has integrated into its workforce planning. Another point of difference is CPB’s in-house design management and engineering expertise; it often adds value by optimising designs for constructability, which can save Defence time and money. Strategically, CPB aligns with DIP-MC’s goal of accelerated delivery: it can ramp up quickly and even undertake multiple project packages concurrently. In short, CPB Contractors’ proven record and comprehensive capabilities make it an essential contributor to the DIP-MC panel, well-suited to lead large, sensitive Defence infrastructure projects from concept to completion ([12]).
Overview and Ownership: Fulton Hogan is a major Australasian civil contractor, originally founded in New Zealand in 1933 and now operating extensively in Australia. Fulton Hogan Construction in Australia is a fully owned subsidiary of the NZ parent company (which is privately owned by shareholders including employees and the Hogan family). The company’s Australian head office is in Melbourne, with regional offices in Sydney, Brisbane, Adelaide and Perth. Fulton Hogan is known for its integrated approach – it owns quarries, asphalt plants, and has in-house teams for surfacing and civil works. With around 8,000 staff across Australasia, it is a top-tier infrastructure builder particularly in roads, airports and utilities. In the Defence sector, Fulton Hogan brings a strong background in airfield and pavement engineering. It has a partnership mentality and often enters joint ventures for mega-projects. The company’s culture, while rooted in Kiwi traditions, emphasizes safety, quality and working “as a family business” even on large projects. It has steadily increased its Australian Defence portfolio in recent years.
Experience in Defence Infrastructure: Fulton Hogan has been delivering and maintaining Defence infrastructure for many years, especially through long-term maintenance contracts in New Zealand. In Australia, Fulton Hogan’s Defence experience has centered on airbase and runway projects – an area where it is considered a specialist. The company has undertaken major airfield upgrade programs at RAAF bases. For example, it was responsible for runway resurfacing and lighting upgrades at RAAF Base Pearce (WA) and the RAAF Gingin airfield ([13]). It also delivered the National Aircraft Pavement Maintenance Programme (2014–2020) for Defence ([13]), which saw Fulton Hogan carry out maintenance on runways and aprons at numerous bases nationwide. In recent years, Fulton Hogan was engaged (in partnership) on the National Airfields Capital Works project, providing constructability advice and works for RAAF Base Amberley (QLD) and RAAF Base Pearce ([14]). The company’s expertise isn’t limited to runways: it has worked on port facilities (given its civil marine capability) and base roads/utilities. Fulton Hogan has also managed Estate Maintenance and Operations Services in NZ defence bases, and this know-how has translated to Australian projects requiring through-life support considerations. Notably, in 2023 data analysis, Fulton Hogan was highlighted as one of SEG’s top suppliers by contract value ([15]), reflecting significant Defence wins. A case in point is Fulton Hogan’s role in a consortium delivering the Shoalwater Bay Training Area Access Roads and remediation – upgrading roads and drainage in that expansive training area (a contract aimed at improving heavy vehicle access to training ranges). Fulton Hogan’s Defence projects often involve complex logistics and working in remote or operational environments, which the company handles through detailed planning and a focus on stakeholder engagement (ensuring, for example, that airfield works don’t impede flying operations).
Points of Difference / Strategic Fit for DIP-MC: Fulton Hogan’s core strength for DIP-MC is its technical mastery of airfield and pavement construction. Few panel members can self-perform large-scale asphalt and concrete paving works as Fulton Hogan can, making it invaluable for projects like runway extensions, tarmac upgrades, or large hardstand constructions at Defence bases. The company also distinguishes itself through a strong culture of collaboration and community engagement. Being partly employee-owned, its teams take pride in project outcomes, which resonates well in partnering models like Managing Contractor or Early Contractor Involvement. Fulton Hogan has a proven track record in mission-critical environments – it understands Defence’s need for reliability and quick turnarounds on infrastructure that directly supports capability ([13]). The company calls itself “the pre-eminent Defence infrastructure services provider in the South Pacific” due to its combined Australian and NZ experience ([13]). This indicates confidence and capacity to deliver under DIP-MC’s demanding scope. Moreover, Fulton Hogan’s integrated supply chain (e.g. its own quarries and asphalt plants) can reduce risk and cost for Defence projects, ensuring materials and resources are available even in remote locales. In terms of Commonwealth procurement objectives, Fulton Hogan is committed to training – it runs apprenticeship programs in civil trades, contributing to the Australian Skills Guarantee by upskilling workers on its projects. The company also has strong relationships with Indigenous subcontractors especially in northern Australia, aiding IPP targets. Strategic fit-wise, Fulton Hogan is ideal for infrastructure-heavy Defence projects (airfields, port upgrades, roads, fuel farms) where its civil engineering prowess complements the building-focused skills of other panelists. Its presence on DIP-MC ensures Defence can call on a contractor that can both construct and maintain critical infrastructure, aligning with long-term sustainability of Defence bases ([13]).
Overview and Ownership: Hansen Yuncken (HY) is one of Australia’s oldest and most respected construction companies. Founded in 1918 in South Australia, it remains Australian-owned and operated, primarily by the founding families and senior management (it is unlisted, private). HY’s headquarters is in Adelaide, with major offices in Sydney, Melbourne, Brisbane and Townsville. The company employs around 600 people. Hansen Yuncken is known as a Tier-2 commercial builder with Tier-1 capabilities, frequently delivering large hospitals, commercial towers, and special-purpose facilities. It prides itself on innovation and was an early adopter of digital construction techniques. In the Defence context, HY has a legacy spanning decades – it built its first defence project in 1938 (facilities at Puckapunyal Military Area) ([16]). HY is entirely Australian-owned, which facilitates security clearances and trust for sensitive projects. The firm often partners in joint ventures for mega-projects, but also successfully delivers as independent head contractor on complex jobs up to ~$300m. Stability, integrity and a focus on quality are hallmarks of Hansen Yuncken’s brand.
Experience in Defence Infrastructure: Hansen Yuncken has a rich portfolio of Defence infrastructure projects, ranging from training facilities and accommodation blocks to high-tech research buildings. In recent years, HY has delivered several notable projects:
- Explosive Ordnance Storage Facilities at Orchard Hills, NSW: a state-of-the-art ammunition compound including blast-proof structures and specialised infrastructure ([16]).
- High-Performance Computing Centre, Edinburgh SA: a cutting-edge data centre for Defence Science & Technology (DSTG) supporting classified research computing ([16]). This involved stringent security and cooling/power resilience requirements.
- Living-In Accommodation (LIA) Upgrades at Puckapunyal, VIC: modernising over 100 accommodation units to contemporary, energy-efficient standards ([16]).
- Land-Based Test Facility (St Kilda, SA) for Navy’s Hunter-class frigates: Hansen Yuncken was engaged as the head contractor for the $65m “Ship Zero” systems testing facility in Adelaide, delivering it with 100% local subcontractor involvement ([17]).
- HY has also built numerous smaller projects: workshops and depots at Robertson Barracks NT, simulator facilities at RAAF Base Williamtown (in partnership, providing roofing solutions ([18])), and refurbishment of Navy training buildings at HMAS Watson, Sydney. Throughout these projects, Hansen Yuncken has demonstrated an ability to meet Defence’s rigorous standards. HY’s decades of work mean it is familiar with Defence’s contracting models; it has worked under both traditional and Managing Contractor arrangements (it served as MC for the Defence Logistics Transformation Program in some regions). The company consistently emphasizes close collaboration with Defence stakeholders – evidenced by its support for on-base events and veteran initiatives, such as sponsoring the Navy Clearance Diver Trust ([16]).
Points of Difference / Strategic Fit for DIP-MC: Hansen Yuncken’s distinguishing feature is deep Defence sector expertise combined with a mid-tier agility. Few contractors on the panel can claim HY’s longevity in Defence work – over 80 years and counting ([16]) – which translates into a profound understanding of Defence’s culture and expectations. HY’s project approach often involves early stakeholder engagement and careful planning to allow construction in live, secure environments (skills honed by working on active bases and with DSTG scientists). This makes it a reliable choice for DIP-MC projects that must be delivered with minimal disruption to military operations. Strategically, HY is strongly committed to local industry participation: on the frigate test facility, it targeted 100% of work to Adelaide businesses ([17]), and regularly achieves high local subcontractor usage and regional upskilling. This aligns perfectly with Defence’s objectives under AIC and the Indigenous Procurement Policy – HY often exceeds Indigenous employment targets (e.g. it achieved 11% Indigenous workforce on Shoalwater Bay project, and 7% Indigenous business spend) ([20]). Another HY advantage is its digital capability – it has an in-house innovation team and has pioneered BIM on Defence jobs to coordinate complex building services. As DISP members, Hansen Yuncken’s personnel hold security clearances, and the company maintains strict cybersecurity for project data. On the DIP-MC panel, HY offers a trusted Australian builder that can take on large projects (up to $300–400m) or specialist components within mega-projects. Its collaborative ethos is well suited to alliance-style delivery if required. In essence, Hansen Yuncken’s blend of experience, commitment to community (e.g. veteran support, local jobs) and technical excellence (in both construction and project management) makes it an ideal strategic partner for delivering major Defence facilities under the panel.
Overview and Ownership: Icon SI (Aust) Pty Ltd is part of the Icon group of construction companies. Icon is jointly Australian and Japanese owned – originally an Australian company, Icon received a major investment from Japan’s Kajima Corporation in 2015, making Kajima the majority owner. Despite foreign ownership, Icon operates as a local builder with its headquarters in Melbourne and significant presence in Sydney, Brisbane, and Canberra. “Icon SI” stands for Icon’s Special Projects/Social Infrastructure division, which focuses on projects in sectors like Defence, health, and education. Icon SI (Aust) is the entity through which Icon bids and delivers Australian Government and Defence contracts. The company has around 1000 staff in Australia and New Zealand. It grew out of Cockram Construction (which had a long history including defence labs and facilities) merging with Icon Co. Icon SI inherits Cockram’s niche expertise in technical facilities and Icon’s broad building capabilities. The company is known for delivering complex projects up to $300m and has a strong track record with government clients. It is an accredited DISP member, reflecting its preparedness for secure Defence work. Icon SI’s regional focus includes Australia’s east coast and it often partners with local firms (including an Indigenous joint venture Barpa, which delivers Defence works at smaller scales).
Experience in Defence Infrastructure: Icon SI (and predecessor Cockram) has solid experience in Defence and related sectors, particularly in delivering specialised technical facilities. A signature project is the Defence Science & Technology Group (DSTG) Fishermans Bend Redevelopment in Melbourne. Icon SI was appointed Managing Contractor for the development phase of this $209 million defence research facility upgrade ([21]), which involves modernising laboratories, constructing a new consolidated office building, and upgrading security and access controls. This project underscores Icon’s capability in high-security, science-oriented Defence projects. Other Defence-related projects include:
- RAAF Base Williamtown: Cockram delivered components of the Air 5428 Pilot Training System facilities (flight simulators and training buildings) at Williamtown and East Sale.
- Maritime Essential Services Centre (MESC) in Sydney: Icon SI has been involved in establishing a support centre for Navy’s fleet (per LinkedIn updates), indicating experience with naval infrastructure.
- Defence Housing and Living Quarters: Icon through Barpa has built and refurbished numerous Living-In Accommodation and housing projects for Defence across Australia (from Robertson Barracks NT to Simpson Barracks VIC), gaining familiarity with base standards and logistics.
- Hanwha’s Armoured Vehicle facility (H-ACE): Icon is nearing completion of a major defence manufacturing facility for Hanwha Defense in Victoria ([8]), working to exacting client specifications. Moreover, Icon’s civilian portfolio – large hospitals, laboratories, data centres – overlaps significantly with Defence needs (in terms of complexity and building services). Icon SI’s Defence projects often involve Early Contractor Involvement to help Defence refine scope and budget. The company has developed strong working relationships with Defence’s estate delivery groups and consultants. For instance, on the DSTG Fishermans Bend project, it works closely with Defence and DSTG scientists to ensure the new facilities meet stringent technical requirements ([21]). Icon SI has also demonstrated skill in stakeholder management – balancing the needs of Defence end-users, base security, and the local community (as seen in Fishermans Bend where it must coordinate with an operating research precinct).
Points of Difference / Strategic Fit for DIP-MC: Icon SI offers the panel a mid-tier contractor with high-tier technical prowess. Its key differentiator is experience in complex, technical building projects – ideal for Defence projects like laboratories, command centres, intelligence facilities, and training simulators that require more than just straightforward construction. Icon SI has a strong focus on risk management and quality (stemming from Japanese corporate influence and Cockram’s legacy), which aligns well with Defence’s no-compromise approach to safety and security. The company also brings the advantage of partnerships with Indigenous enterprises: through Barpa Pty Ltd (a JV with an Indigenous business), Icon can enhance Indigenous participation on DIP-MC projects and meet or exceed IPP targets. For example, Barpa/Icon have delivered dozens of smaller Defence projects with significant Indigenous workforce involvement. In terms of the Australian Skills Guarantee, Icon runs graduate programs and participates in industry training initiatives, ensuring apprentices and cadets get opportunities on its sites. Icon SI is nimble enough to adapt to various delivery models – from fixed-price builds to managing contractor roles – providing Defence with flexibility. Its DISP accreditation and security-conscious culture mean it can handle projects requiring secret-level clearances without lengthy onboarding. Furthermore, being backed by Kajima gives Icon SI financial stability and access to international expertise (Kajima has built defence facilities in Japan), enhancing its resilience on the panel. Strategic fit: Icon SI is well-suited to medium-large Defence projects that are complex but not necessarily the biggest by value (say $50m–$300m range), complementing the mega-project focus of some Tier-1s. In the DIP-MC mix, Icon SI strengthens the panel by ensuring projects with specialized requirements can be delivered by a team attuned to Defence’s technical and security demands – evidenced by its MC role on DSTG’s $209m lab redevelopment ([21]).
Overview and Ownership: Laing O’Rourke Australia is the Australian arm of Laing O’Rourke, a global engineering and construction firm headquartered in the UK. The company is privately owned by the O’Rourke family. In Australia, Laing O’Rourke established itself in 2006 (after acquiring Barclay Mowlem) and is now a top-tier contractor with offices in Sydney (head office), Brisbane, Melbourne, Perth, and Darwin. It employs around 3,500 people in Australia. Laing O’Rourke Australia is known for its integrated digital engineering, direct delivery of complex works, and off-site manufacturing capabilities. It operates as a single company, but for contracting/licensing purposes has multiple entities (including a separate Qld entity, LORAC and LORQ – see LORQ profile). The Australian operation functions with a high degree of autonomy, although it draws on UK expertise and capital. Laing O’Rourke has been a major partner to Defence; it is an accredited DISP member and one of the few contractors with an enduring dedicated Defence team. The company’s focus on innovation, safety, and megaproject delivery has made it a preferred contractor for some of Defence’s most ambitious infrastructure programs.
Experience in Defence Infrastructure: Laing O’Rourke (LOR) has one of the strongest portfolios in Defence infrastructure among private contractors. It has delivered numerous large projects via Managing Contractor (MC) arrangements. A standout project is the Australia-Singapore Military Training Initiative (ASMTI) – Shoalwater Bay Training Area Redevelopment in Central Queensland. LOR was appointed Managing Contractor in 2018 for this ~$800m project, leading the development of new facilities and upgraded infrastructure across 4,500 km² of training area ([22]). The project, completed in 2025, delivered state-of-the-art headquarters, accommodation for ~300 troops, weapons ranges and urban operations training facilities. LOR successfully managed a complex stakeholder environment (Australian Army, Singapore Armed Forces, traditional landowners, environmental regulators) ([22]), and was praised for its collaborative approach and indigenous engagement – exceeding targets with 11% Indigenous workforce and 7% spend on Indigenous businesses ([20]). Beyond Shoalwater Bay, Laing O’Rourke’s Defence résumé includes:
- Holsworthy Barracks, Sydney: Redevelopment of specialist forces facilities and infrastructure upgrades.
- RAAF Base Amberley: Laing O’Rourke has undertaken significant projects at RAAF Base Amberley, notably the Battlefield Airlifter Project, which involved upgrading facilities to accommodate the C-27J Spartan aircraft. This project encompassed the construction of new hangars and support facilities.
- Larrakeyah Defence Precinct, Darwin: LOR (as MC) is delivering major components of this $500m redevelopment, including a new wharf (Kuru) and base infrastructure improvements ([23]).
- Gallipoli Barracks, Brisbane: Upgrades and new facilities under Defence’s base consolidation programs.
- Various sustainment projects: LOR undertakes ongoing minor works and sustainment for Defence, reflecting trust beyond big capital projects. Laing O’Rourke is especially noted for delivering projects in Northern Australia. For example, it is constructing new infrastructure at Robertson Barracks and RAAF Darwin for US Force Posture Initiatives. The company’s use of prefabrication has benefited Defence projects by speeding up construction in remote areas – e.g., modular bathroom pods and pre-cast elements for barracks, produced in its off-site facility in Western Sydney, then transported to site. LOR’s Defence experience also extends to partnering with tech firms on new capabilities: it has built simulation centres and is abreast of requirements for guided weapons storage, etc., due to internal engineering expertise.
Points of Difference / Strategic Fit for DIP-MC: Laing O’Rourke’s proposition to the DIP-MC panel is its end-to-end capability on large, complex projects. It can take a project from early design through to commissioning, utilising its in-house digital engineering team to model and solve problems upfront. Defence has benefited from this on Shoalwater Bay, where LOR’s digital rehearsals helped manage environmental and cultural heritage constraints ([22]). A key point of difference is LOR’s Design for Manufacture and Assembly (DfMA) approach – the company heavily uses off-site manufacturing (precast structures, modular components) to improve quality and safety. This is particularly valuable for Defence sites in remote regions or with tight timelines (e.g., quickly deployable facilities). Strategically, LOR is deeply aligned with Defence’s goals around Indigenous participation and local industry. In Shoalwater, LOR engaged the Darumbal people meaningfully in the project ([20]), and across its projects it often exceeds AIC targets – over 80% of subcontracts by value on Shoalwater Bay went to regional Queensland businesses ([20]). The company’s commitment to innovation and sustainability (aiming for renewable energy use on sites, efficient designs) also dovetails with Defence’s evolving ESG and energy resilience objectives. Laing O’Rourke has a long-term partnership mentality with Defence: many of its project directors and engineers specialize in Defence work, ensuring continuity of knowledge. As part of DIP-MC, Laing O’Rourke is well-suited to manage large-scale, multi-stakeholder projects (like base redevelopments involving numerous facilities) and those requiring coordination with foreign defence forces or allies (as seen in ASMTI). Its proven ability to deliver on time in challenging conditions makes it a go-to for high-priority initiatives where failure is not an option. In summary, Laing O’Rourke’s innovative construction techniques, strong stakeholder engagement, and proven track record on complex Defence programs underscore its strategic value to the panel ([22]).
Overview and Ownership: LORQ Building Pty Limited is a regional operating entity of Laing O’Rourke Australia, focusing on Queensland. It is fully owned by Laing O’Rourke and effectively acts as the Queensland construction business unit. The creation of “LORQ” allows Laing O’Rourke to hold a Queensland builder’s licence and meet local statutory requirements; in practice the team and resources are part of Laing O’Rourke’s integrated national operations. LORQ is based in Brisbane, with project offices in regional QLD (such as Rockhampton and Townsville). As a subsidiary of a UK-based firm, LORQ is foreign-owned but Australian-run, and it adheres to Laing O’Rourke’s global standards. The company is mid-sized in QLD but has the backing to scale up for very large projects. LORQ has a strong regional ethos – many staff are long-term Queensland residents or recruited from local industry. It often partners with local contractors in joint ventures for major work in the state. Its focus aligns with Defence’s heavy footprint in Queensland and the Northern Territory.
Experience in Defence Infrastructure: LORQ (Laing O’Rourke Queensland) has been central to delivering Defence projects in Queensland and the northern regions. Under the umbrella of Laing O’Rourke, it played the lead role in the Shoalwater Bay Training Area Redevelopment (ASMTI Central) in QLD ([22]). A dedicated project office in Rockhampton managed that project for several years, underscoring LORQ’s local presence. LORQ has also undertaken works at Lavarack Barracks in Townsville – including upgrades to 3rd Brigade facilities and new training centres. In Townsville, the company established a base office and engaged with the local supply chain heavily during those projects. Another example is LORQ’s involvement in the early works for the new Greenvale Training Area in North Queensland (ASMTI North): though the main contract went to another firm, LORQ was shortlisted and contributed to scoping, bringing insights from Shoalwater. In Brisbane, LORQ delivered significant portions of the Gallipoli Barracks Redevelopment in Enoggera (the Hardened & Networked Army program in late 2000s), constructing workshops, accommodation and a simulated urban training facility. Additionally, LORQ has worked on RAAF Base Amberley projects, such as an aircraft maintenance hangar and engine test cell. Through its Darwin office (under the QLD business unit), LORQ is constructing elements of the Larrakeyah (Darwin) redevelopment in the NT, including base entry precinct works that it was awarded as a subcontractor ([24]). LORQ’s project delivery often emphasizes local subcontractor involvement – for Shoalwater Bay, the QLD team managed 167 work packages with over 80% awarded to Queensland contractors ([20]). This experience in packaging and managing numerous local subs is valuable for other Defence projects in the state. Furthermore, the QLD team is adept at dealing with Queensland’s climate and geography (e.g. building in tropical conditions, cyclone codes, etc.) – knowledge crucial for Defence infrastructure in that region.
Points of Difference / Strategic Fit for DIP-MC: LORQ’s main strength is its regional expertise and on-the-ground network in Queensland, which ensures that major Defence projects in the state are delivered efficiently. For DIP-MC, having a Queensland-focused entity like LORQ means Defence can engage a contractor who already knows the local government regulations, workforce and cultural landscape. This reduces ramp-up time for projects in QLD (and the NT which LORQ often services). LORQ embodies Laing O’Rourke’s overall capabilities – including advanced digital engineering and prefabrication – applied through a regional lens. For example, on Shoalwater Bay, the Queensland team leveraged the company’s off-site manufacturing to deliver building modules, which sped up construction in the remote training area ([22]). LORQ also has a track record of close collaboration with the ADF units in its project areas; during Shoalwater Bay, the team worked hand-in-hand with Army range control and the Singaporean liaison officers, demonstrating cultural sensitivity and flexibility. As part of DIP-MC, LORQ is strategically well-suited for projects under the Integrated Investment Program that are based in QLD/NT – such as further training area expansions, RAAF Base Townsville upgrades, or any new facilities in the Cape York or Torres regions. LORQ’s commitment to local industry (it routinely hits high local content percentages) supports Commonwealth economic goals, and its familiarity with Indigenous communities in QLD (engaging traditional owners like the Darumbal at Shoalwater ([20])) supports IPP and native title considerations. In summary, LORQ offers the panel a proven Defence builder in Queensland with the full backing of Laing O’Rourke’s innovations and resources. This combination ensures that DIP-MC projects in northern Australia can be delivered by a team that is both locally grounded and globally capable, a strategic asset for Defence.
Overview and Ownership: Lendlease Construction (Southern) Pty Ltd is a regional entity of Lendlease, a global property and infrastructure company founded in Australia. Lendlease is publicly listed on the ASX but headquartered in Sydney, and it remains Australian-managed. “Construction (Southern)” denotes the arm covering primarily the southern states (Victoria, South Australia, Tasmania, and sometimes ACT), whereas Lendlease Construction Pty Ltd (without qualifier) covers other regions – both are part of the same integrated Lendlease Building business. Lendlease is one of Australia’s largest tier-1 contractors, with around 13,000 employees globally (several thousand in Australia). It has a long history in Defence construction dating back to the post-WWII era. The Southern division, with offices in Melbourne and Adelaide, has delivered many projects for Defence in those regions. Lendlease is known for its strong financial stability, comprehensive development and construction services, and a corporate ethos emphasizing safety and sustainability. It is Australian-owned and a trusted partner to government clients, with extensive governance processes in place.
Experience in Defence Infrastructure: Lendlease (Southern) has delivered a wide range of Defence projects, including some of the most complex facilities for Navy and Army in the south. Key experiences include:
- HMAS Cerberus Redevelopment (VIC): Lendlease Southern was the managing contractor for this ~$500m upgrade of the Navy’s training base on Mornington Peninsula. This involved new training schools, accommodation, a large gym/aquatic centre and base infrastructure renewal ([25]).
- RAAF Base East Sale (VIC): Delivered new training facilities and flight simulators for pilot training (PC-21 project), including a flying school headquarters and accommodation for trainees.
- Garden Island (East), Sydney – Stage 1 (NSW but managed by Southern unit): Upgrade of wharves and base services for the naval base ([25]).
- HMAS Watson Redevelopment (NSW): A Navy training college upgrade in Sydney, overseen by Lendlease’s southern team ([25]).
- Land 121 Facilities (multiple states): As part of Army’s Land 121 project, Lendlease built vehicle shelters, workshops and warehouses across Victoria (Bandiana), SA, and Tasmania ([25]).
- JP2008 and AIR555 facilities: Secure communications and intelligence facilities at Edinburgh SA and elsewhere as part of Defence’s high-tech programs. In addition, Lendlease Southern has delivered numerous smaller projects such as upgrades at Woodside Barracks (SA) and RAAF Woomera range improvements. Notably, Lendlease’s Southern entity was recently engaged in the LAND 19 Phase 7B Short Range Air Defence facilities at Woodside/Edinburgh (supporting Raytheon’s NASAMS system), given its footprint in SA. Lendlease distinguishes itself by handling sensitive projects – for instance, it built the Joint Logistics Units in Moorebank NSW (the Moorebank Units Relocation, a huge logistics facility) in partnership ([26]), and though that was led by LOR, Lendlease was heavily involved via its development arm. Within the southern region, Lendlease often acts as the prime contractor under Managing Contractor forms, coordinating multiple works packages with Defence and consultants. An example is the Navy Capability Infrastructure Program (NCIS) projects in SA – Lendlease is delivering wharf and support facilities in support of naval capability (like at Port Adelaide) ([25]). Across these projects, Lendlease has shown strength in managing complex design and maintaining operations – e.g., at Cerberus, training continued while construction replaced decades-old utilities. The company’s internal Defence team has longstanding relationships with Defence Estate & Infrastructure Group and the base command units, which facilitates problem-solving and quick decisions.
Points of Difference / Strategic Fit for DIP-MC: Lendlease brings an unparalleled depth of experience and a multi-disciplinary skill set to DIP-MC. It has decades of institutional knowledge – as Lendlease itself notes, it has delivered “major capability, redevelopment, and complex projects, including high-security facilities for the Army, Navy, and Air Force” across Australia ([25]). This breadth means Lendlease can handle everything from airfields to simulators to wharves under one contract. A key differentiator is Lendlease’s focus on sustainability and innovation: it often targets high environmental ratings for Defence buildings (like Green Star ratings for accommodation, or incorporating solar/energy efficiency in base upgrades). For DIP-MC, where Defence seeks not just cost-effective but also future-proof infrastructure, Lendlease’s approach is valuable. Strategically, Lendlease Southern is attuned to delivering projects in partnership with Defence and local industry. For example, on the Hunter frigate test facility in SA, Lendlease (as builder) implemented a local industry participation plan that saw 100% of work go to Adelaide firms ([17]). This commitment to local content and training aligns with Commonwealth policies (AIC and ASG). Lendlease’s strong safety culture and proven record also reduce risk for Defence on large projects. Additionally, Lendlease has the capacity to finance and develop projects if needed (it has undertaken PPPs like the Defence HQ JOC at Bungendore via a consortium). This could be useful if Defence ever looks to alternative financing for certain infrastructure. As part of DIP-MC, Lendlease Southern is especially suited for major southern region projects – e.g. continued works at HMAS Cerberus, expansion of RAAF Edinburgh’s R&D facilities, or even construction of the forthcoming Guided Weapons factories – all of which require managing complex stakeholders and technical requirements, something Lendlease excels at. In sum, Lendlease Construction (Southern) offers the panel a tier-1 contractor with unmatched Defence pedigree, capable of delivering mission-critical infrastructure while meeting the highest standards of compliance, security, and community benefit ([25]).
Overview and Ownership: Lendlease Construction Pty Ltd is the main entity for Lendlease’s construction business outside the Southern region – effectively covering New South Wales, Queensland, the ACT and Northern Territory. It operates under the same Australian publicly listed parent, Lendlease Corporation. This entity (sometimes referred to as Lendlease Building) is headquartered in Sydney and represents the continuation of Lendlease’s 60+ years involvement in Australian construction. The ownership is public (with significant Australian and some foreign investors), but strategically it is an Australian company and one of the government’s key partners in infrastructure. Lendlease Construction has a large workforce (the bulk of Lendlease’s Australian construction employees) including engineers, project managers and site trades. It often teams up with Lendlease’s development and investment divisions on integrated projects. With a strong balance sheet and multi-billion dollar turnover, Lendlease can take on the largest Defence contracts. It maintains rigorous governance, risk management and sustainability programs enterprise-wide.
Experience in Defence Infrastructure: Lendlease’s contribution to Defence infrastructure is vast and historic. In the northern and central regions, Lendlease has:
- RAAF Base Tindal Redevelopment Stage 6 (NT): Lendlease is the Managing Contractor for this $737m upgrade and expansion of RAAF Tindal’s airfield and base facilities ([11]). Work includes lengthening runways, new fuel farms, explosive ordnance storage, and expanded utilities to support US aircraft deployments. Lendlease commenced these works in 2020, and notably initiated local industry expos to involve Katherine community businesses and apprentices ([11]).
- RAAF Base Williamtown (NSW) – Air 6000 Phase 2A/B: Lendlease delivered critical facilities for the introduction of the F-35A Lightning II. This included squadron headquarters, maintenance hangars, integrated training centre and ordnance loading aprons ([27]). These works (2014–2018) were complex, fast-tracked and required coordination with US stakeholders.
- Holsworthy Barracks (NSW): Lendlease had major roles in the Hardened & Networked Army projects at Holsworthy, building new special forces facilities, a combined mess and other support infrastructure.
- Single LEAP Phase 2 PPP (All states): Lendlease (with partners) delivered thousands of new live-in accommodation units across 14 bases under a Public-Private Partnership. Lendlease Building was responsible for constructing many of the accommodations in NSW, QLD, and WA (in partnership with local builders like Richard Crookes, Watpac etc.) ([4]).
- Garden Island & Fleet Base East (NSW): Under NCIS (Navy facilities program), Lendlease has delivered upgrades to wharf infrastructure and is involved in new submarine-related facilities planning.
- Headquarters Joint Operations Command (HQJOC) near Canberra: While delivered as a PPP by a consortium (Praeco) in 2008, Lendlease was a key member managing design and construction of this high-security defence HQ.
Lendlease often operates under collaborative contract models; Defence frequently trusts it with Early Contractor Involvement (ECI) roles to refine project scopes. Its project teams are adept at stakeholder consultation (e.g. liaising with base commanders, user reps, and even allied forces on joint facilities). A hallmark of Lendlease’s Defence projects is a strong focus on social outcomes – e.g., local employment and training initiatives, and engaging veteran-owned businesses as suppliers where possible.
Points of Difference / Strategic Fit for DIP-MC: As one of Defence’s longest-standing construction partners, Lendlease offers continuity and deep institutional knowledge. It understands Defence procurement and governance intimately; for instance, Lendlease’s project executives are well-versed in the Public Works Committee processes and the need for cost transparency, which eases the administrative burden on Defence. The company also excels at handling multi-facility programs – something DIP-MC will often require (bundling several projects under one panel contractor). Lendlease’s large team means it can run multiple major projects concurrently across various states, providing scalability to the panel. It also leads in compliance and quality – with certified systems for safety, environment, and security (DISP Level 3). On the Tindal project, Lendlease set a target of 70% local participation and created opportunities for Indigenous enterprises, aligning with IPP and demonstrating commitment to community. Its effort to hold a trades expo for Katherine students and businesses during the Tindal works ([11]) is an example of the added value Lendlease brings – workforce skilling and community engagement beyond the contract itself. In terms of technical capability, Lendlease’s breadth allows it to incorporate advanced technology (for example, it has used digital twins for asset management handover on Defence sites) and sustainable design (Net Zero Carbon initiatives in new Defence buildings). Strategically, Lendlease is often the benchmark for delivery of large Defence projects – its name attached gives stakeholders confidence (which is why it’s entrusted with flagship projects like JSF facilities and Tindal expansion). For DIP-MC, having Lendlease on the panel ensures Defence has a highly reliable option for the most critical or challenging projects, where its comprehensive approach – “design, project manage, and deliver mission-critical infrastructure” ([25]) – will be invaluable. In essence, Lendlease Construction Pty Ltd is a cornerstone of the panel, equipped to drive successful outcomes on Australia’s biggest Defence infrastructure investments.
Overview and Ownership: Multiplex is a global construction contractor that originated in Australia (est. 1962) and is now owned by Brookfield Business Partners (Canadian). It operates in Australia as Multiplex Constructions, headquartered in Sydney, with offices nationwide (Brisbane, Melbourne, Perth, etc.). Despite foreign ownership, Multiplex retains a strong Australian identity and workforce. It employs around 1,800 people in Australia and is known for delivering iconic high-rise buildings, hospitals, and large-scale infrastructure. Multiplex has historically focused on commercial construction but has diversified. It has enormous financial capacity as part of Brookfield and can tackle projects well above $1bn. Within Defence, Multiplex was traditionally less prominent, but in recent years it has actively pursued Defence work, aligning with a strategic goal to expand into this sector ([28]). The firm’s culture emphasises engineering excellence and timely delivery – it built skyscrapers and stadiums under challenging deadlines, a trait beneficial to Defence. Multiplex is accredited under DISP (for handling classified projects) and has invested in understanding Defence procurement, recently establishing a Defence business unit.
Experience in Defence Infrastructure: Multiplex’s direct experience in Defence infrastructure has ramped up over the last few years. A noteworthy engagement is Multiplex being appointed Managing Contractor for the development phase of the RAAF Base Curtin Redevelopment in WA (Kimberley region) ([28]). This ~$244m project involves refurbishing and improving remote base facilities including runways, accommodation, and fuel infrastructure. The selection of Multiplex in 2023 for RAAF Curtin signalled Defence’s confidence in its capability to deliver in a remote defence environment ([29], [28]). Multiplex is also understood to be involved in the new Missile Manufacturing and Maintenance Facility at Astra Aerolab Business Park adjacent to RAAF Base Williamtown. The facility will be occupied by Kongsberg Defence Australia. Construction expected to be completed by the middle of 2026. Missile manufacturing will begin from 2027, ramping up to full rate production by the end of 2028.
In addition, Multiplex delivered three of the Australian Government’s “Centre for National Resilience” quarantine facilities during COVID (in Perth, Melbourne, and Brisbane) under fast-track contracts ([28]). While not Defence projects, these were on Commonwealth-owned land and required rapid, secure construction of accommodation camps – analogous in many ways to Defence accommodation or deployable facilities, giving Multiplex relevant experience in mobilising and building quickly to a standard design.
These experiences demonstrate Multiplex’s growing familiarity with Defence’s strict specs and stakeholder environment. Importantly, the company has brought on senior project leaders with Defence backgrounds to guide its entry into the market. Multiplex’s ability to handle large workforces and subcontractors was seen in its rapid delivery of the 1,000-bed quarantine village in Brisbane within months – a skill directly useful for, say, quickly constructing base expansions or temporary facilities for exercises.
Points of Difference / Strategic Fit for DIP-MC: Multiplex’s entry into Defence via DIP-MC adds a contractor with immense delivery horsepower and a fresh perspective. A key point of difference is its proven ability to mobilise at short notice and deliver fast-track projects. The company explicitly noted that delivering the quarantine centres under tight timeframes mirrored the requirements of Defence panel projects ([28]). Multiplex also brings strong design management and value engineering skills – on complex builds like hospitals, it routinely optimises designs; similarly, for Defence, it can provide innovative solutions to meet function while controlling costs. Its ambition to expand in Defence has led Multiplex to commit top leadership attention to these projects. For DIP-MC, this means Defence clients will get a highly motivated contractor eager to prove itself and “expand further in the Australian defence sector” ([28]). Multiplex has highlighted its focus on involving local communities and offering training on remote projects: at RAAF Curtin, it sees a “major opportunity… to increase sustainable employment opportunities, cadetships and apprenticeships” in the Derby/Kimberley region ([28]). This aligns perfectly with the ASG and IPP aims – Multiplex is effectively using the Defence project to upskill local and Indigenous workers. Furthermore, Multiplex’s global backing by Brookfield gives Defence an extra layer of financial security and access to global supply chains (useful for specialised equipment or modular solutions). The strategic fit is evident in scenarios where Defence might need large-scale infrastructure delivered concurrently (Multiplex’s capacity means it could build, for example, multiple large buildings or a whole base village in parallel). Additionally, Multiplex is well-versed in working under strict safety and quality regimes (like mining/Oil&Gas sector projects it has done), so Defence’s stringent EHS requirements will be met. In summary, Multiplex adds to the panel a contractor that is resource-rich, fast and eager, with the ability to handle urgent or unusually large projects with fresh energy. Its track record on RAAF Curtin’s initial phase will likely solidify its reputation as a Defence-ready builder that can be entrusted with expanding northern bases and other major initiatives ([28]).
Overview and Ownership:
Multiplex Constructions Qld Pty Ltd operates as the Queensland arm of Multiplex, a global tier-one builder owned by Brookfield. While fully integrated into the national organisation’s systems and standards, Multiplex Qld maintains a regional focus, with its main office in Brisbane and a track record of delivering major commercial projects across South-East Queensland. The division draws on Multiplex’s national workforce while cultivating local capability and supply chains. It maintains strong internal delivery capacity, particularly in structural and concrete works.
Project Experience in Queensland:
Multiplex Qld has successfully delivered several large-scale projects in Brisbane, reinforcing its capability in complex, high-profile builds:
- 1 William Street, Brisbane: A 46-storey commercial tower completed in 2016 that houses the Queensland Government’s executive offices. This flagship project showcases Multiplex’s high-rise commercial capability in Brisbane.
- Queen’s Wharf Tower (part of Queen’s Wharf Brisbane): Multiplex is the builder delivering key stages of this major city-shaping precinct. The project involves significant civil, structural, and architectural works and is one of Queensland’s largest ongoing developments.
- Brisbane Quarter – W Brisbane Hotel and 300 George Street: A mixed-use development comprising luxury hotel, commercial, and residential towers, constructed by Multiplex and completed in stages from 2018.
- Centre for National Resilience – Brisbane (Pinkenba): Delivered in 2022 as a Commonwealth project responding to the COVID-19 pandemic, this facility featured over 500 modular accommodation units and support infrastructure. Multiplex was engaged as the managing contractor, demonstrating its ability to rapidly deliver high-spec accommodation facilities under federal oversight – capabilities relevant to Defence contingency works.
Alignment with Defence and Remote Works:
While Multiplex Qld has limited direct Defence delivery experience to date, its execution of the Pinkenba quarantine facility showed the ability to deliver at pace, under strict compliance regimes, and with the logistical complexity comparable to deployed-force accommodation.
Its workforce includes individuals with prior Defence project experience, and the division is currently supporting national Defence works, such as the redevelopment of RAAF Base Curtin in WA, by contributing project personnel. The division also has internal familiarity with regional logistics and infrastructure, having delivered complex commercial and health projects across Queensland.
Points of Difference for Defence Infrastructure:
- Rapid Deployment Capability: The Pinkenba project showed Multiplex Qld’s ability to mobilise quickly and build modular, scalable accommodation with integrated amenities – a key asset for contingency Defence infrastructure.
- Integration with National Resources: As part of a national organisation, Multiplex Qld can scale quickly by drawing in labour and specialist expertise from other states.
- Financial Strength and Procurement Reach: Being backed by Brookfield, the company has secure financial foundations and access to global supply chains, which was evident during the pandemic response when it sourced international modular units.
Conclusion:
Multiplex Constructions Qld offers the Defence estate sector a capable tier-one builder with experience in high-security, rapid-delivery projects and the ability to scale nationally. While relatively new to direct Defence contracts, the business has transferable experience, proven systems, and an emerging interest in supporting remote and strategic base upgrades in Northern Australia.
Overview and Ownership: Richard Crookes Constructions (RCC) is a prominent mid-tier Australian construction company, privately owned by the Crookes family. Founded in 1976, it is based in Sydney and operates across NSW, the ACT, and Queensland. RCC has about 600+ employees and is highly regarded for delivering projects in education, residential, industrial, and government sectors. As an Australian-owned builder, RCC values long-term client relationships and has a reputation for reliability and no-fuss delivery. The company remains under family leadership (Richard Crookes’ descendants) and fosters a hands-on, solutions-focused culture. In Defence, RCC is a known quantity, having been involved in numerous base projects especially in NSW and the ACT. It has pre-qualified status for Defence works and DISP membership. The company’s regional offices (Newcastle, Canberra) give it local reach near major bases (Williamtown, Majura). RCC often competes in the Tier-2 space where projects range up to ~$200m, though it has also partnered on larger ones.
Experience in Defence Infrastructure: Richard Crookes Constructions has amassed considerable Defence infrastructure experience, particularly in delivering accommodation and training facilities:
- Single LEAP Phase 2 (NSW sites): RCC played a major role in this Defence PPP for single soldier accommodation. It was responsible for constructing new Live-In Accommodation blocks at HMAS Albatross (Nowra), RAAF Base Wagga, and Blamey Barracks Kapooka (Wagga) ([4]). This involved building hundreds of en-suite units and recreational facilities on base, all delivered to a tight timeline in 2012–2014.
- ADFA Redevelopment (ACT): RCC is the Managing Contractor for the current Australian Defence Force Academy redevelopment in Canberra ([19]). This ~$250m project (Phase 1 delivered in 2021, Phase 2 underway) includes a new 1,200-seat auditorium, enhanced teaching facilities, and upgraded cadet accommodation and amenities ([19]). It’s a logistically challenging project within an operating military university, demonstrating RCC’s capacity for complex builds.
- Multi-Role Helicopter (MRH-90) Facility, Holsworthy Barracks, New South Wales: RCC delivered the construction of a purpose-built facility for the MRH-90 Taipan helicopters at Holsworthy Barracks. This project included the development of hangars, maintenance workshops, and associated infrastructure to support the operational readiness of the MRH-90 fleet. The facility meets the stringent requirements of Defence aviation and ensures the continued operational effectiveness of these critical assets.
Through these experiences, RCC has proven adept at meeting Defence’s compliance requirements and working within active base environments. For example, during the Single LEAP builds, RCC had to coordinate site works amidst daily base routines and deliver turnkey buildings with communications and security systems in place for immediate use ([4]). The ADFA project further highlights RCC’s stakeholder coordination skills, balancing the needs of Defence personnel, university staff, and cadets.
Points of Difference / Strategic Fit for DIP-MC: Richard Crookes Constructions brings the panel a highly dependable mid-tier contractor with specific expertise in Defence living and training facilities. Its family-owned ethos often translates to a personal commitment to project success – Defence clients frequently note RCC’s cooperative and can-do approach on site. For DIP-MC, RCC’s strengths lie in projects that might be too large for a small builder but not massive enough to require a top-tier – the $20m to $200m range, where RCC can offer cost-effective delivery. A point of difference is RCC’s track record of collaboration in PPPs and managing contractor roles; it understands not just construction, but also long-term maintenance considerations (from Single LEAP PPP experience). This means RCC thinks about whole-of-life performance, adding value in design phases. RCC also has a strong safety and quality record, which is crucial on Defence bases to avoid incidents that could disrupt military activities. It is very much in tune with Commonwealth procurement values: on ADFA, RCC achieved high local content by engaging Canberra region subcontractors extensively, and it regularly meets Indigenous participation goals via engagements with Indigenous trade contractors (for instance, in Nowra and Wagga areas where Indigenous firms were employed on Single LEAP works). Additionally, RCC’s relatively lean corporate structure can yield faster decision-making and adaptability – useful if Defence needs to adjust scope or handle emerging requirements (like adding a building at short notice, which RCC can accommodate without layers of corporate approval). Strategically, having RCC on DIP-MC gives Defence a trusted option for medium-scale projects and specialist facilities. Its knowledge from building simulation centres, accommodation and classrooms means it can handle upcoming needs like cyber training centres or barracks refurbishments expertly. RCC also complements larger panellists: it could act as a delivery partner or JV partner on mega-projects, bringing local insight and augmenting capacity. Overall, Richard Crookes Constructions’ proven Defence experience and reliable, value-for-money delivery make it an excellent strategic fit for the DIP-MC panel, particularly for projects focusing on the “people” side of Defence capability (living, training and working environments) ([4], [19]).

Overview and Ownership: Sitzler is a proudly Australian-owned construction company with a legacy of over 50 years, based in Darwin, Northern Territory. Founded in 1976, it remains family-owned (by the Sitzler and Margetic families ([32])) and has grown to be the Northern Territory’s largest local contractor. Sitzler has also expanded with offices in Townsville, Adelaide, Canberra, Perth, and Brisbane ([32]). Despite its modest size compared to multinationals, Sitzler punches above its weight in delivering large projects, especially for Defence and remote area works. The company employs around 400 staff and is well-known for its commitment to the community and Indigenous engagement. Sitzler’s reputation in the construction industry is one of reliability, practical problem-solving and on-time delivery in challenging conditions (tropical climate, remote logistics). It has been a trusted partner on Defence projects in northern Australia for decades. Notably, Sitzler was ranked #12 in ADM’s 2024 Top 40 Defence Contractors list (the highest of any privately-held builder), reflecting its substantial Defence portfolio ([33]). The firm is DISP accredited and many of its personnel carry high-level security clearances, enabling work on sensitive projects.
Experience in Defence Infrastructure: Sitzler is arguably the most experienced Defence infrastructure contractor in Northern Australia. Its project experience spans:
- RAAF Base Tindal (NT) – AIR7000 Phase 1B Triton FOB: Sitzler was awarded the contract to design and construct the new facilities at Tindal to support the MQ-4C Triton unmanned aircraft. This includes high-span maintenance hangars, operations and training buildings, and supporting infrastructure (aprons, fuel, comms). This project, valued around $270m, commenced 2024 and is critical to Australia’s UAV capability ([15], [34]).
- LAND 19 Phase 7B SRGBAD Facilities (RAAF Edinburgh SA): Sitzler is delivering the facilities for Army’s new short-range air defence system (NASAMS) at Edinburgh, SA ([15]). This ~$210m project provides working accommodation for 16 Regiment and specialized simulators, storage and weapon maintenance areas. Sitzler committed to 98% local procurement and substantial Indigenous involvement on this job ([32]), showcasing its approach to community engagement.
- Robertson Barracks & HMAS Coonawarra (NT) – Single LEAP Phase 2: Sitzler delivered 232 new accommodation units at HMAS Coonawarra in Darwin and 686 units at Robertson Barracks as part of the Single LEAP program ([4]). These were multi-storey living quarters completed in 2013, collectively worth over $100m, significantly improving troop living standards in the Top End.
- Larrakeyah Defence Precinct Redevelopment (NT): Sitzler has been deeply involved in this $500m project. It delivered the new base entry precinct and other major packages under Laing O’Rourke’s MC oversight ([24]), and also constructed the new Kurru (Larrakeyah) Wharf – a 250m long naval wharf completed in 2022, enabling larger Navy vessels to berth in Darwin ([35], [36]).
- Delamere Air Weapons Range (NT): Sitzler upgraded facilities at this remote bombing range, including new target infrastructure and range control buildings.
- Various NT and Qld projects: Sitzler built the Norforce Unit headquarters in Darwin, the Mt Bundey Training Area upgrades, and in Townsville, it has delivered training facilities for 3rd Brigade. The depth of Sitzler’s experience is evidenced by data: in 2023, within Defence Infrastructure Division, Sitzler was the top supplier by contract value – securing two major contracts (Tindal Triton and LAND19) totalling $515m ([15]). This is a remarkable achievement, highlighting Defence’s trust in Sitzler for big-ticket projects. Sitzler’s projects often involve working closely with Defence units on the ground – for example, it has coordinated with USAF personnel for jointly used facilities at Tindal, and with ADF trainers at Robertson. The company is adept at delivering in remote locales, staging construction around extreme weather (wet season downtime, etc.), and managing long supply chains – key competencies for Defence’s northern estate.
Points of Difference / Strategic Fit for DIP-MC: Sitzler’s value to DIP-MC cannot be overstated – it offers unmatched experience in remote and regional Defence construction. A hallmark of Sitzler is its genuine commitment to local industry and Indigenous participation, far exceeding contractual requirements. On the LAND19 Edinburgh project, Sitzler targeted 98% local spend and achieved over 5% engagement of Indigenous enterprises and 8% Indigenous workforce ([32]), significantly contributing to IPP outcomes. This community-focused approach aligns perfectly with Defence’s social procurement aims. Another point of difference is Sitzler’s agility and flexibility; as a mid-size contractor, it can adapt quickly to changes and maintain close, family-business style oversight on projects. Many Defence stakeholders appreciate dealing directly with Sitzler’s owners and long-standing project managers, which speeds up decision-making. Strategically, having Sitzler on DIP-MC ensures Defence projects in northern Australia (where much of the Integrated Investment Program is focused) are in the hands of a contractor who intimately understands the environment. Sitzler has proven it can deliver complex, highly technical facilities (hangars, ordnance storage, comms facilities) to top quality – showing that regional contractors can match Tier-1 capabilities. Its presence also encourages a competitive, value-for-money dynamic on the panel, since Sitzler often has lower overhead costs than multinationals while delivering equal outcomes. Sitzler is also deeply familiar with Commonwealth procurement and contracting models; it has successfully performed under Managing Contractor, Design & Construct, and Construct-Only models on Defence jobs. The company’s long-term commitment to Defence (it has had a continuous portfolio of Defence work for decades) means it is invested in Defence’s outcomes beyond individual projects. In conclusion, Sitzler brings to DIP-MC a powerful combination of remote area expertise, cultural alignment with Defence values, and a track record of delivering large Defence projects on budget and on time. As evidenced by its recent high-profile projects and top supplier status ([15]), Sitzler is strategically crucial for ensuring the success of major Defence infrastructure initiatives, particularly in Australia’s north.

One unique aspect of DIP-MC is that not all panel contractors are licensed in every state or territory. The panel was established with a jurisdictional matrix to ensure that only appropriately licensed builders work in each region. In practice, this means Defence will only invite tenders from panel companies that hold the necessary building licence for the project’s location.
The jurisdictional coverage matrix above highlights that some panellists have truly national reach (e.g. Acciona, Laing O’Rourke, CPB, Hansen Yuncken – all licensed in most states), while others are more regionally focused (for instance, Sitzler is NT-based, and Built Qld operates only in QLD). This diversity was intentional: Defence can foster local industry participation by including regional builders, while still ensuring every state/territory has multiple panel options.
For panel contractors, it’s critical to maintain your licences in all regions where you intend to work. If your licence lapses or you didn’t initially secure one for a state that projects pop up in, you risk missing opportunities. Conversely, non-panel firms with specific regional licenses might find opportunities if panel coverage in an area is thin – Defence can always go outside the panel if no suitable licensed panellist is available, though that scenario is expected to be rare.
(Note: DISP accreditation status is also indicated in the matrix (Yes/No). DISP membership is not mandatory to be on the panel, but Defence strongly encourages contractors to have appropriate DISP membership to handle classified information and access bases. More on DISP later in this guide.)
