On 12 November, Australia and Indonesia concluded negotiations on a new bilateral security treaty in Sydney, jointly announced by Australian Prime Minister Anthony Albanese and Indonesian President Prabowo Subianto. The treaty commits both nations to regular consultations at the leader and ministerial levels on security matters, and to consult and consider joint or individual measures if either nation’s security is threatened. This agreement, which builds on the 2024 Defence Cooperation Agreement, significantly enhances defence cooperation and signals a deeper partnership aimed at maintaining regional stability amidst geopolitical competition. The treaty is expected to be formally signed in January 2026.
