The Defence Infrastructure Panel – Major Contractors (DIP-MC) isn’t just for the 18 panel contractors – it creates real opportunities for subcontractors, suppliers and consultants. Here’s how you can get involved.
1. Track Projects and Engage Early
DIP-MC covers all major Defence projects over $200M. While EOIs may no longer be announced on AusTender, many are flagged in Defence’s Integrated Investment Program and listed on DECNet.com.au. If you’re a subcontractor or consultant, find out which projects are coming and which panel contractors are likely to bid. If, for example, a project is planned in WA, reach out early to panel members licensed in that state. Head contractors often start forming delivery teams and pricing supply chains well before tenders go out.
2. Network Where It Counts
Attend Defence and industry events, including DECNet briefings, to meet panel contractor reps. Come prepared – know their current projects and explain how you can add value. Whether you bring local knowledge, an innovative solution, or past performance with the panel, those relationships matter. Familiarity and trust often influence which subs get invited to quote.
3. Align Your Pitch with Panel Goals
Panel contractors must meet Defence objectives – Indigenous participation, local content, sustainability and skills development. Position your offering to help them deliver on those goals. For example, if you’re an Indigenous-owned firm or have sustainability credentials, highlight it. If you can save time or cost in design or delivery, frame your pitch around that. The more your value aligns with what panel contractors need, the more appealing you’ll be.
4. Be Defence-Ready
Defence projects demand high standards. Ensure your WHS systems are strong, clearances are in place (or underway), and that you understand the security and compliance obligations (including DISP membership if relevant). Defence work often involves tight terms, insurance requirements, and strict reporting. Having these things in order removes barriers to working with panel contractors.
5. Be Flexible and Collaborative
Success on panel projects often depends on being responsive. Participate early, contribute ideas (not just quotes), and be willing to work within evolving scopes and deadlines. If you’re a smaller business, team up with others to offer a broader solution. Panel contractors value subs and consultants who help them de-risk and deliver.
6. Share Your Wins
If you’ve contributed to a panel project, promote it (with permission). Case studies and internal referrals carry weight. Let other panel members know about your successful contributions – it might help you win the next job.
In short, even if you’re not on the panel, you can still play a key role in delivering its projects.
Security, Safety, and Other Reminders
All participants in DIP-MC projects – panel contractors, subcontractors, and consultants – must meet high standards for security, safety, and compliance. Here are key reminders:
Security & Clearances:
Panel contractors should hold DISP membership (ideally Level 2+ for classified work, or at least Level 1). Subcontractors can sometimes operate under the head contractor’s security umbrella, but having your own DISP status is advantageous and may be required. Personnel may also need Baseline or NV1 clearances depending on the project. Start clearance processes early – waiting until award is too late.
Work Health and Safety (WHS):
All DIP-MC projects exceed $4M, so head contractors must be accredited under the Federal Safety Commissioner’s WHS Scheme. While subcontractors aren’t required to hold accreditation, they must comply with equivalent standards. A strong, documented WHS system is essential. If you’re delivering large or complex packages, consider seeking accreditation to stay competitive.
Training and Skills Compliance:
Personnel working on Defence sites must complete mandatory training – this could include security, cultural heritage, environmental awareness, or explosive ordnance protocols. Keep qualifications current and maintain a workforce plan that supports the Australian Skills Guarantee, including tracking apprentice and trainee hours.
Administration and Audits:
DIP-MC simplifies paperwork but doesn’t eliminate it. Be prepared to maintain full records, submit regular reports, and support audits from Defence or ANAO. Use of systems like CEMAR or PMKeys may be required. Clear documentation and transparency help avoid problems and build trust.
Being prepared in these areas reinforces your reliability and boosts your chances of future work.
Ready to Succeed with DIP-MC?
In summary, while the DIP-MC panel may appear exclusive at first glance, it opens the door to significant opportunities for subcontractors and consultants who are ready to engage strategically. By understanding the panel’s priorities, maintaining high compliance standards, and building relationships early, non-panel firms can become essential partners in delivering Defence’s largest infrastructure programs. The key is to align with the panel ecosystem – not just in capability, but in values, responsiveness, and readiness. Defence projects are complex and demanding, but for those who are prepared, the DIP-MC offers a clear and scalable pathway into the heart of Australia’s Defence infrastructure pipeline.
