Australia has invested heavily in the language of the rules-based order. It is a practical middle-power promise: sovereignty matters, coercion is constrained, and legitimacy is built through law, institutions, and restraint. Just as importantly, it speaks to a broader strategic equilibrium – an Indo-Pacific in which no country dominates, and no country is dominated in the oft-repeated words of Foreign Minister Penny Wong.
In Southeast Asia, that promise does real work. It reassures neighbours that Canberra’s posture is meant to steady the region, not sharpen it, and that alliance commitments do not automatically become a blank cheque for force.
That is why the Albanese government’s response to US–Israeli strikes on Iran is worth unpacking calmly, not because Iran is an easy case, but because it is a hard one.
Prime Minister Anthony Albanese’s has said Australia “supports the United States acting” to prevent Iran obtaining a nuclear weapon and to prevent Iran continuing to threaten international peace and security. This statement, made soon after the strikes commenced, also framed solidarity with the Iranian people’s struggle against oppression. Read together, the message landed as more than concern about proliferation; it sounded like early political validation of kinetic action, offered with fewer visible legal guardrails than Australia usually puts forth when speaking about order.
Iran is not a minor detail in this story. Tehran’s nuclear trajectory has long generated fear and instability, and its domestic repression is real. Australia is also right to warn citizens when escalation increases risks, including travel disruption. Wong, in her remarks, drew pointed reference to the non-proliferation architecture – IAEA findings and long-running international concerns about compliance – which is where the debate should sit if the objective is to prevent proliferation without widening conflict.
But the ordering of emphasis matters. In Southeast Asia, the first line that a leader chooses is rarely treated as incidental. It is taken as a clue to instinct: whether a government reaches first for legality and de-escalation, or for alliance affirmation and moral messaging. The region’s policy community is attuned to hierarchy and reflex because the costs of misreading great-power dynamics are not abstract. “Rules” matter in part because they can still, sometimes, restrain power.
Does that discipline show up when it is inconvenient, or only when it is cost-free?
I teach Australian politics and foreign policy in Indonesia, and the most persistent challenge in explaining Canberra to Southeast Asian audiences is not hostility to Australia; it is how quickly crisis moments revive old shorthand. The “deputy sheriff” stereotype has endured for decades not because nuance is impossible, but because nuance is hardest to sustain when leaders move fast. When endorsement appears to come first, and legal or de-escalatory framing is left implicit, the stereotype hardens into “common sense” – and it becomes a ready-made lens through which everything else is interpreted.
That matters because reputation is not decoration in the Indo-Pacific. The view of a country shapes room to manoeuvre. Australia’s influence in Southeast Asia rests not only on capability but on persuasion, and credibility depends on whether Australia’s conduct matches the story it tells. A government can insist it upholds the rules-based order, but regional audiences ask a sharper question: does that discipline show up when it is inconvenient, or only when it is cost-free?
A coherent case can be made for Australia’s approach. Iran’s nuclear program is destabilising, allied credibility is not costless, and rapid statements in moments of escalation are shaped by consular concerns, deterrence logic, and the desire to reduce uncertainty among partners. Those considerations are real. The problem is not that Australia values its US alliance – it should – but that the public posture risks overwhelming Australia’s distinct middle-power pitch. It leaves a simpler, less flattering reading: alliance first, rules second.
This is an awkward moment because strategic flux in the region coincides with unpredictability in American domestic politics. If Australian leaders want to sustain trust in Southeast Asia, the country’s anchor cannot be the shifting temperament in Washington. It must instead be the habits Australia claims as its own – discipline in favouring rules, careful framing, and a visible preference for de-escalation and process.
The fix does not require Australia to abandon its US alliance or pretend that Iran is not dangerous. It requires an emphasis on the rules-based order, especially at times under stress.
The credibility gap narrows when Canberra makes its guardrails visible early. That means spelling out the legal frame it is relying on, keeping de-escalation pathways in view from the outset, and avoiding language that can be read as open-ended validation of force. Moral clarity about repression does not have to be tied to endorsement of kinetic action.
Australia will always face moments when alliance obligations and regional credibility pull in different directions. The skill of middle-power diplomacy lies in refusing the false choice. Alliance solidarity can be expressed without closing off the options for diplomacy. Deterrence can be pursued without giving the impression that rules become optional when friends are acting.
Australia has built a reputation in Southeast Asia on the promise that it is more than an extension of someone else’s strategy, and that it supports a regional equilibrium where no country dominates and no country is dominated. In a sharper, less predictable world – including inside the United States itself – that promise is not one to be discarded. It is one of the few assets that consistently makes Australia persuasive in the region. If Canberra wants its rules-based story to survive the moments that test it, the discipline to stick to the message has to be the first instinct.
