Australia and Papua New Guinea (PNG) on Monday signed a landmark mutual defense agreement, marking Canberra’s first such pact in 70 years and underscoring efforts to bolster regional security amid growing geopolitical tensions in the Pacific.
The treaty commits both nations to recognize an armed attack on either as a threat to the peace and security of both, effectively binding them closer in defense cooperation. It also opens doors for joint military recruitment and training initiatives, a first in PNG’s history.
According to the joint statement, consultations will soon begin on a recruitment pathway allowing PNG citizens to serve in the Australian Defence Force (ADF). Starting January 1, 2026, eligible permanent residents of Australia who are also PNG citizens will be able to apply to join the ADF — a move aimed at deepening defense and cultural ties between the two neighboring nations.
“This alliance is built on generations of mutual trust,” said Australian Prime Minister Anthony Albanese, adding that the agreement reflects both countries’ “commitment to ensuring the Pacific remains peaceful, stable, and prosperous.”
The deal represents a major step in Australia’s broader strategy to enhance regional security partnerships across the Pacific, aligning with similar defense cooperation efforts with the United States, Japan, and other Indo-Pacific allies.
