During a September 2 testimony at the Aukus Public Inquiry—an independent, crowdfunded review of the trilateral security pact—Michael Pezzullo, a former deputy secretary of strategy in Australia’s Department of Defence, used Indonesia as a hypothetical example of an 'aggressive' regional actor. Pezzullo’s comments were intended to illustrate the strategic necessity of the Aukus agreement, which involves Australia, the United Kingdom, and the United States.

Analysts have characterized the remarks as 'clumsy diplomacy,' warning that they could revive historical suspicions between the two nations. Indonesia and Australia have been working to bolster their security ties, and observers suggest that framing Indonesia as a potential threat—even in a hypothetical context—undermines these diplomatic efforts. The incident highlights the delicate balance Australia must maintain as it navigates its commitment to the Aukus alliance while simultaneously fostering a stable relationship with its closest northern neighbor.

While the Aukus pact is primarily viewed by its proponents as a counterweight to broader regional power shifts, the specific inclusion of Indonesia in a scenario regarding regional aggression has caused unease. The controversy underscores the sensitivity of regional security discourse, where hypothetical strategic scenarios can have tangible impacts on bilateral trust. As of now, the Australian government has not formally commented on the potential fallout from Pezzullo’s testimony, but the reaction from regional experts suggests that the comments have created an unnecessary hurdle in the ongoing dialogue between Canberra and Jakarta.
