Henderson has long supported Australia’s fleet, but under the NSSG’s consolidation plan, it will become the beating heart of naval capability on the west coast.
At the recent WA Defence Summit, two senior Defence leaders outlined one of the most ambitious infrastructure programs in Australia’s history: the Henderson Consolidation. Rear Admiral Michael Houghton, Head of Patrol Boats and Specialist Ships, and Helen Loundes, Assistant Secretary for Henderson Consolidation, presented the Commonwealth’s plan to transform Henderson into a world-class, Commonwealth-owned naval precinct.
For consultants and contractors, the keynote made one thing clear: this is a once-in-a-generation opportunity for infrastructure delivery.
Why Henderson Matters
“Henderson is one of the two principal shipbuilding precincts in Australia,” RADM Houghton said. “It plays a key role in delivering continuous naval shipbuilding, surface fleet classes, submarine sustainment, as well as upgrades for vessels to accelerate military preparedness”.
The precinct’s strategic importance has grown since the Defence Strategic Review (2023) identified Australia’s maritime capability as central to deterrence. The National Defence Strategy (2024) reinforced that view, prioritising speed to capability and investment in sovereign shipbuilding.
Henderson will complement Osborne in South Australia as the twin anchors of Australia’s naval shipbuilding enterprise. But unlike Osborne, Henderson’s remit extends to Army’s littoral manoeuvre fleet and the sustainment of allied vessels visiting from the Indian Ocean.
A Program Measured in Decades
Helen Loundes described the consolidation as “one of Defence’s largest ever infrastructure projects,” with costs running into the tens of billions over coming decades.
The program is phased. An initial $127 million planning package is already underway, funding cost plans, scheduling, stakeholder consultations, preliminary designs, and feasibility studies. “Think of building a house, just on the biggest scale,” Loundes said. “You don’t rush your planning, else you’re going to be going back and doing rework – and that’s more costly”.
Delivery will stretch over more than a decade, sequenced to align with shipbuilding and sustainment needs while minimising disruption to existing operations at Henderson.
The Projects on the Horizon
Henderson will host an impressive list of new and ongoing programs:
- Landing Craft (LAND 8710): 18 medium landing craft and eight heavy landing craft for Army, a $2 billion program creating around 1,100 direct jobs.
- Pacific Patrol Boat Replacement: 24 Guardian-class vessels gifted to Pacific nations, with sustainment ongoing.
- Cape-class Patrol Boats: Eight delivered, with more under construction for Navy and Border Force.
- Arafura-class Offshore Patrol Vessels: Six to be built at Henderson, with the first already commissioned.
This pipeline underpins the rationale for consolidation. As Houghton explained: “The challenge we face is an industrial maritime capability challenge. Military capability and industrial capability go together”.
Strategic Shipbuilding Agreement
A major development is the Strategic Shipbuilding Agreement (SSA), establishing Austal Defence Australia as the precinct’s strategic shipbuilder. “Through the SSA we aim to create greater efficiencies and deliver a sovereign shipbuilding capability in WA,” Houghton said.
The SSA will streamline contracting, cut lead times between contract award and steel-cut, and provide a stable pipeline of work. Importantly, it’s not a vertically integrated model. Instead, it’s a distributed build: “A ship designer will come to the strategic shipbuilder with a ship to be built. The strategic shipbuilder will productionise the design, subcontract out components, and then consolidate it back together”.
For contractors, this opens the door to supply-chain participation across fabrication, systems integration, and specialist trades.
Infrastructure Delivery Opportunities
The scale of works required is vast:
- Marine infrastructure: dredging, new breakwaters, and heavy-duty wharves.
- Dry docks and ship lifts: including nuclear-certified facilities to support AUKUS submarines.
- Assembly and sustainment halls: capable of handling frigates and large support vessels.
- Utilities and enabling works: high-voltage power, cyber-secure networks, roads, and housing.
As Loundes emphasised, “Local and regional industry are critical to this sovereign shipbuilding and sustainment enterprise. Defence will work closely with you to maximise the benefits and mitigate impacts”.
Even in the planning stage, contracts are emerging. A design services consultancy tender was released in August, with contract award anticipated later this year.
Workforce and Supply Chain Challenges
Henderson is expected to generate around 3,000 sustainment jobs and several thousand construction roles. But, as Houghton warned, “The success of this program is dependent on industry’s flexibility, agility, and innovation as much as our own”.
Competition with WA’s resources sector for labour and materials will be fierce. Loundes noted Defence is working with the WA Government to avoid “overheating the market” and triggering the kind of cost and labour pressures seen in past mining booms.
Workforce development initiatives – including a Defence TAFE Centre of Excellence and the expansion of the Defence Industry Pathways program – are underway to help build the talent pipeline.
Implications for Defence Estate Planning
Henderson signals a shift in how Defence approaches its estate. Instead of piecemeal upgrades, this is precinct-level planning: a coordinated build integrating federal and state infrastructure, local government input, and industry partnerships.
The cooperation agreement between Canberra and Perth exemplifies this, with WA responsible for state-owned user facilities and the Commonwealth for defence infrastructure. This joined-up approach may become the template for future precincts, such as Osborne’s submarine facilities or an eventual east coast SSN base.
It also reinforces that defence estate planning is about more than wharves and workshops. Housing, transport, training, and community engagement are now part of the equation. As Loundes put it, “Collaboration and regular engagement… is pivotal to enable this significant and complex undertaking to succeed”.
Engaging with Industry: Transparency and Updates
Loundes acknowledged the strong appetite from WA industry for information about the Henderson program. “Industry and community will be engaged regularly to provide updates. I know you feel as though you probably haven’t heard enough… We are desperately trying to make sure we have something of use”.
She outlined Defence’s approach: formal industry forums, targeted small group sessions, and even informal “pop-up” engagements. “Collaboration and regular engagement… is pivotal to enable this significant and complex undertaking to succeed”.
To improve transparency, Defence will also begin publishing a quarterly Henderson Defence Precinct newsletter, alongside updates to its dedicated website. Loundes encouraged interested businesses to subscribe and stay informed.
For contractors, this commitment to openness means early visibility of project sequencing, upcoming tenders, and opportunities to provide feedback during design and planning stages.
Conclusion: A Call to Industry
The Henderson Consolidation is a bold undertaking. It will reshape WA’s industrial landscape and anchor Australia’s maritime defence strategy for decades. For infrastructure consultants and contractors, the opportunities span the full spectrum of planning, design, and delivery.
As RADM Houghton reminded the audience, “Speed to capability is one step we are taking in order to deliver”. Meeting that demand will require innovation, scale, and close collaboration across government and industry.
For those in the Defence infrastructure sector, now is the time to engage. Henderson is not just another project – it is a generational program that will test, and showcase, the best of Australia’s infrastructure delivery capability.
