Indonesia and Australia are expanding their security cooperation to include Japan and Papua New Guinea (PNG). Indonesian Defence Minister Sjafrie Sjamsoeddin announced the planned trilateral arrangements following a meeting with his Australian counterpart Richard Marles on March 12, 2026. This expansion builds upon a recent security treaty signed between Indonesia and Australia, which committed both nations to joint military training and increased information sharing. The potential development of a joint defense training facility on Morotai Island in Indonesia was also discussed. These moves aim to support a secure and peaceful Indo-Pacific region, leveraging existing defense pacts Australia has with both PNG and Japan.
