Australia’s Strategic Ambiguity Is Running Out of Road

Washington wants allies to spend more on defense, while Beijing judges Australia by what it does, not what it says. Canberra needs to take stock of its own interests.

U.S. Secretary of War Pete Hegseth delivers his speech to the IISS Shangri-La Dialogue 2026 in Singapore, May 30, 2026,

At the 2026 Shangri-La Dialogue in Singapore, U.S. Secretary of War Pete Hegseth delivered a message Australia cannot afford to ignore. He sounded what he called a “rightful alarm” over China’s rapid military buildup, warned against any single power dominating the Indo-Pacific, and urged regional allies and partners to lift their defense spending.

At the same time, Hegseth struck a more measured tone toward Beijing, despite China sending only a lower-level delegation to the Shangri-La Dialogue for the second year in a row. He spoke of strategic stability, military-to-military contact, and the need to avoid miscalculation. He made no direct mention of Taiwan and, when asked about future arms sales, declined to give a firm commitment.

For Australia, the speech could mark a turning point. Canberra is being asked to spend more and align more closely with U.S. strategy just as Washington’s commitments look less predictable and Beijing becomes less patient with Australia’s strategic ambiguity.

In Hegseth’s framing, Australia sits among Washington’s model allies, alongside Japan, South Korea, and others. Facing a more contested strategic environment, Australia needs greater military capability, more resilient supply chains, and a larger defense-industrial workforce.

But beyond the question of whether Australia should spend more is the question of whether Canberra has a clear strategy for what that spending is meant to achieve.

Australia’s 2026–27 defense budget is about A$62.6 billion, or 2 percent of GDP – well below the 3.5 percent level being urged by Washington. Meeting that target would have serious economic consequences. Every additional dollar committed to submarines, missiles, bases, and sustainment must be weighed against productivity, infrastructure, universities, and industrial policy.

AUKUS illustrates the dilemma facing Canberra. The latest announcements streamline Australia’s pathway to acquiring three in-service Virginia-class submarines from the United States and expand cooperation on undersea technologies. 

This is where Australia’s strategic autonomy is narrowing. More of its security choices are being locked into allied systems, platforms, and assumptions. AUKUS ties Australia’s future submarine capability to U.S. and U.K. industrial capacity, training systems, and nuclear stewardship. Meanwhile, deeper force-posture cooperation, intelligence sharing, and defense-industrial integration reinforce operational dependence. 

On the other hand, Australia’s choice is made........
