Australia and the Philippines have signed a new Defence Cooperation Arrangement, strengthening bilateral defence ties and maritime security cooperation during Prime Minister Anthony Albanese’s visit to Manila on Sunday (15 Nov).

The agreement updates the existing defence cooperation framework, expanding collaboration on maritime domain awareness, information-sharing, strategic dialogue, training, interoperability and defence infrastructure. It coincides with the 80th anniversary of diplomatic relations between the two countries.

Key developments

  • The arrangement enhances cooperation on maritime security, defence planning and military interoperability.
  • Australia will expand investment in its Southeast Asia Maritime Partnerships, supporting maritime awareness, cyber resilience and regional security capabilities.

The agreement reflects a broader trend of closer defence cooperation between Australia and the Philippines as both countries expand practical security collaboration across the Indo-Pacific. 

While Australian officials said the arrangement is intended to strengthen regional stability, maritime resilience and cooperation with ASEAN partners rather than target any specific country, it comes amid continued regional focus on maritime security, freedom of navigation and adherence to international law.
