By Global Leaders Insights Team | Nov 12, 2025
Australia and Indonesia have signed a new bilateral security treaty to strengthen defence cooperation and regional stability. The deal was announced on Wednesday in Sydney by Australian Prime Minister Anthony Albanese and Indonesian President Prabowo Subianto.
The treaty commits both countries to consult each other if either nation’s security is threatened and to consider joint or individual responses. It expands on earlier agreements made nearly 30 years ago and aims to formalise security coordination between the two neighbours.
Prime Minister Albanese called the pact a “major extension” of the defence relationship, saying it reflects both nations’ shared interest in maintaining peace in the region. President Prabowo said the agreement underscores their “determination to maintain the best of relationships” and to improve mutual security.

The treaty also introduces regular high-level security talks, moving from occasional meetings to structured dialogue. It focuses on practical cooperation, including military training, intelligence sharing, and joint responses to emerging threats.
Although it does not include a mutual defence clause, analysts say the agreement represents a step forward in building trust and closer defence ties between Australia and Indonesia.
