Australian Prime Minister Anthony Albanese and Fijian Prime Minister Sitiveni Rabuka signed a mutual defence treaty in Suva, Fiji, on Monday, July 6, 2026 [1].
The agreement represents a strategic shift in Pacific security as Australia seeks to counter the expanding influence of China in the region [2].
The pact, titled the Ocean of Peace Alliance, establishes a formal commitment where both nations agree to aid one another in the event of an attack [3]. This treaty marks the fourth formal defence alliance established by Australia [4].
Officials said that two agreements were signed during the summit in Suva [5]. The move is intended to strengthen regional security cooperation, and ensure stability across the Pacific islands [2].
The alliance comes amid increasing geopolitical competition for influence in the South Pacific. By formalizing this security tie, Australia reinforces its role as a primary security partner for Pacific Island nations while creating a collective deterrent against external pressures [2].
The signing ceremony took place in the Fijian capital, where both leaders said the importance of regional sovereignty and mutual support [5].
“The Ocean of Peace Alliance commits both nations to provide military aid if either is attacked.”
The Ocean of Peace Alliance signals a hardening of Australia's security posture in the Pacific. By moving from general cooperation to a mutual defence treaty, Canberra is establishing a more concrete military framework to limit Chinese strategic expansion. This shift suggests that Australia views the current security environment as requiring formal deterrents rather than just diplomatic engagement.
