AUKUS Pillar II is an industrial coordination challenge, not just a technology opportunity

Western Australia enters the AUKUS era with genuine strategic advantages. AUKUS, the trilateral security partnership between Australia, the United Kingdom and the United States, presents a significant opportunity for Western Australia's defence industry. HMAS Stirling, Australia's most strategically significant naval base, is the home of the Australian submariner community. The Submarine Rotational Force – West is already ramping up. The Australian Marine Complex at Henderson sustains an established Defence and commercial shipbuilding and sustainment industry. WA's resources sector has spent three decades developing autonomous systems, remote operations and logistics engineering capability that is at the core of the AUKUS Pillar II advanced capabilities agenda.

 A foundation however, is not the same thing as a coherent defence industrial ecosystem. The gap between the two is a place of challenge and opportunity, and the West Australian Government’s new Western Defence Forge concept represents an important step forward in how this space can be bridged.

 Technology isn't the constraint

AUKUS Pillar II is the advanced technology component of the Australia-UK-US defence partnership, designed to accelerate collaboration on next-generation defence capabilities. It targets advanced capabilities across undersea warfare, artificial intelligence and autonomy, electronic warfare, cyber, quantum and hypersonics. The conventional answer to the question of how WA captures this opportunity runs along familiar lines: more funding, more innovation programs, more direct Defence contracts. That answer is not wrong, but it misidentifies where the binding constraint actually sits.

WA's defence-tech firms are not short of technology nor innovative capacity. Autonomous systems capability developed for mine sites and offshore energy is directly applicable to undersea and air domain programs. Signals and communications expertise built for remote resource operations translates readily to electronic warfare and contested environments. The critical challenge is translating these innovations into delivered Defence capability at the scale and pace the Defence Integrated Investment Program demands.

The missing middle

The entire Australian defence industrial base has a structural problem that WA shares. Shaped like an hourglass, at the apex sits a small number of international prime contractors, sophisticated and capable of integrating complex systems. At the base sit tens of thousands of small, technically capable firms. Between them sits a missing middle.

That missing middle tier is not a minor inefficiency. It is the structural gap that determines whether Defence investment produces enduring national capability capable of strategic resilience, or a succession of promising innovations, then prototypes, that never reach operational service.

Mid-tier companies are the industrial layer that integrates components into subsystems, manages complex supply chains, absorbs technical risk, and provides the scalable manufacturing and logistics capacity that converts a successful test into a sustained program. Without a credible mid-tier, the pathway from AUKUS Pillar II investment to fielded capability remains broken at precisely the point where it matters most.

The capability gap beyond funding

The language of “the valley of death”, that commercial funding gap between R&D and revenue, looms large in all technology and innovation discussions. Rarely said however it that the valley of death has two walls, not one.

Many firms that secure initial investor or even direct Defence funding subsequently stall not because they run out of capital, but because they lack the program management discipline, supply chain maturity and delivery controls capability that Defence requires as a customer. Earned value management, schedule performance measurement, contract reporting obligations, and subcontractor flow-down requirements are not bureaucratic impositions. These are the commercial language that Defence contracting requires industry to speak. Firms that cannot speak it do not scale in the defence sector. The capability maturity gap is at least as significant a barrier as the funding gap, and considerably less discussed.

Building WA's defence industrial ecosystem

Closing that gap requires deliberate investment in industrial infrastructure alongside investment in technology. Structured programs are needed to build supply chain and project controls capability across the Tier 2 and Tier 3 industrial base. Collaborative contracting mechanisms should give emerging mid-tier firms the sustained program exposure needed to develop systems integration capability, without asking them to carry risks beyond their scale. Workforce development must build program management and logistics engineering disciplines alongside the technical skills that already attract investment and attention.

Here WA has a specific advantage that is frequently underestimated: a dual industrial heritage. The resources sector has produced a generation of engineers, project managers and supply chain professionals accustomed to operating in remote, high-consequence environments under rigorous schedule and cost discipline. That workforce competence is directly transferable to defence programs. But bridging mechanisms must exist to make the transfer.

Building those mechanisms deliberately, rather than waiting for them to emerge organically, is the industrial policy work that WA's defence-tech ambitions now require.

This means treating AUKUS Pillar II as an industrial development challenge, not primarily a technology funding opportunity. Western Defence Forge is the right mechanism at the right time to capture this opportunity by addressing all facets of the missing middle challenge on an integrated basis. The technology exists. The strategic demand is clear. The enabling policy, business and productivity models are available. Advancing Western Defence Forge as industrial architecture will connect them.
