The Scale of the Ask
Around 10,000 jobs over two decades — that is the workforce projection attached to the Henderson Defence Precinct and associated submarine sustainment activity at HMAS Stirling. The WA Government has been explicit about its ambition: defence is to become the state's second-largest industry within ten years, trailing only mining and resources. The 24 August 2026 site announcement turned that ambition into a program with a boundary, a budget and a clock.
The problem is that Western Australia already runs one of the tightest labour markets in the country. The Henderson build-out will draw on the same pools of boilermakers, welders, marine engineers, project managers, electricians and ICT specialists that keep the resources sector running — and it will do so while the resources sector is itself expanding.
Competing with Resources — on Salary and on Security
Defence does not just compete with mining on wages. It competes with an additional friction the resources sector does not carry: security. Precinct work requires DISP-member employers, AGSVA-cleared personnel for classified roles, and — for AUKUS packages — export control screening that can exclude workers on nationality grounds alone. A tradesperson choosing between a mine site and a shipyard faces higher pay and fewer hurdles at the mine.
Commonwealth engagement around the announcement has explicitly acknowledged the need to protect the resources sector from disruption caused by AUKUS-related activity — a rare public admission that the two sectors are drawing from a finite labour and contractor base, and that growing the pool matters more than poaching from it.
The Clearance Bottleneck
The least discussed constraint is not labour scarcity at all — it is clearance throughput. AGSVA Baseline and NV1 processing takes months under normal conditions, and demand across the AUKUS enterprise is rising sharply. A business that wins a Henderson package and then begins clearance processing for its workforce has already lost months. The businesses that will mobilise fastest are the ones initiating clearances and DISP membership now, during the concept design phase, rather than after contract award.
For employers, personnel security is not an administrative afterthought — it is a DISP domain in its own right, with obligations around clearance sponsorship, foreign contact reporting and ongoing suitability assessment. Our guide to DISP requirements sets out what the personnel security domain actually demands.
The Training Pipeline Is Real but Slow
The pipeline response is underway. Western Australia launched its first naval nuclear foundations training course earlier this year — accredited by Curtin University and backed by HII and Babcock — as we covered in our AUKUS workforce briefing. Apprenticeship programs, tertiary partnerships and skilled migration pathways are all part of the precinct's long-term workforce strategy. But training pipelines take years to produce cleared, experienced tradespeople, and the concept design phase is happening now.
What Employers Should Do Now
- Plan workforce as a delivery risk, not an HR issue. Labour availability and cost escalation belong in your tender pricing and program timing from day one.
- Initiate clearances early. Identify the staff who will hold classified roles and start AGSVA processing before you need them cleared.
- Get your own house in order. DISP membership, Essential Eight ML2 and a documented personnel security framework are prerequisites for precinct work — and differentiators in a market where many competitors will not be ready.
- Use the pipeline. Engage with the vocational and tertiary programs being stood up for the precinct rather than competing solely for experienced hires.
Serious Defence helps WA businesses build the compliance foundation that precinct work demands — from DISP readiness programs to the DISPulse platform that keeps personnel security and clearance tracking audit-ready. The workforce race has started; the compliance race started earlier.
