Strategy

By Robbin Laird

Australia is unlikely to be the public face of Pax Silica, but it may prove to be one of its most consequential enabling powers. The emerging United States-led architecture suggests that the states best positioned to shape the next international order will not be limited to those building frontier AI systems. They will also include states that control the minerals, energy, logistics, and strategic geography on which the entire compute stack depends.

Architecture, Not Isolated Deals

The central insight animating the current strategic debate is that a series of apparently separate diplomatic and commercial moves now fit together as components of a coherent design. In this reading, the Abraham Accords provide the diplomatic chassis; Pax Silica and AI ‘factories’ supply the infrastructure layer; F-35 sales and regional security integration furnish the hard-power lock-in; and dollar-linked digital rails may yet become the monetary backbone of an AI-centered international order.

This framework matters for Australia because it shifts analysis away from a narrow conversation about trade policy or critical-minerals exports. It positions Canberra inside a larger American effort to organize trusted technology ecosystems among allies and partners—linking industrial policy, supply chains, defense alignment, and digital infrastructure into a single strategic system.

Where Australia Fits

Australia’s role in such an order is not to replicate Silicon Valley, Taiwan, or South Korea. Its real value lies deeper in the stack: critical minerals, reliable energy, secure geography, maritime access, and proximity to the Indo-Pacific theater where supply-chain resilience has become a strategic imperative rather than merely a commercial preference.

This makes Australia a foundational state in Pax Silica rather than a symbolic one. If the twenty-first century runs on compute, then compute still depends on the physical conditions that make chip production, data infrastructure, and trusted logistics possible—and Australia possesses several of those conditions in unusually concentrated form.

A Supplier of the Bottom Half of the Stack

One way to understand Australia’s contribution is to view it as a supplier of the bottom half of the AI stack. Pax Silica is not, in the narrow sense, only about semiconductors. It encompasses a larger system of cloud platforms, security ecosystems, critical-minerals processing, and the physical infrastructure required to operationalize American technological leadership.

Australia already sits near the center of that supporting system. It holds reserves of critical minerals essential across advanced manufacturing chains, possesses the land and energy potential relevant to large data and industrial facilities, and commands alliance relationships that make it a trusted node for long-horizon industrial commitments in ways that most other resource states cannot match.

The key policy question for Canberra is whether Australia remains a mere upstream extractor or uses the Pax Silica framework to move into processing, refining, energy-intensive industrial activity, and secure infrastructure. If Australia supplies ore while others capture processing, compute, and defense-industrial leverage, it will matter to the order without fully shaping it.

Australia as an Indo-Pacific Anchor

Pax Silica is best understood as a growing network of carefully selected states chosen for their place in the AI supply chain and their broader strategic relevance. In that context, Australia is an Indo-Pacific anchor: a state whose geography and alliance position allow it to connect the American technology order to maritime Asia and the wider Southern Hemisphere.

This role reaches well beyond minerals policy. Australia can contribute to secure undersea cable networks, trusted port and shipping corridors, energy supply for AI-related infrastructure, and the strategic depth that a coalition requires if it is to be resilient against disruption or coercion.

From this perspective, AUKUS, critical-minerals diplomacy, and participation in technology coalitions should not be treated as separate policy files. They are better understood as interlocking components of a common...
