Australia has taken a major step in strengthening its relationship with Pacific neighbours by formalising a historic defence alliance with Papua New Guinea while unveiling a $250 million investment to expand rugby league across the region. The twin announcements reinforce Canberra’s long-term commitment to regional security, development and people-to-people connections.
The newly activated Pukpuk Treaty officially establishes Australia and Papua New Guinea as formal defence allies. It marks Papua New Guinea’s first alliance with any nation and Australia’s first new defence alliance in more than seven decades, reflecting growing strategic cooperation between the two neighbours.
Under the treaty, both countries have pledged to consult, cooperate and respond together should either nation face an armed attack. Leaders from both sides emphasised that the agreement respects national sovereignty while promoting peace, stability and shared security across the Pacific region.
Alongside the security agreement, Prime Minister Anthony Albanese announced a $250 million commitment over the next decade to support the Pacific Rugby League Partnership. The funding forms part of a broader $600 million regional rugby league initiative aimed at strengthening ties through sport.
The partnership will work with Papua New Guinea, Fiji, Samoa and Tonga to develop grassroots competitions, youth participation, elite pathways and women’s rugby league. Governments believe sport can create opportunities for education, leadership, employment and stronger community engagement across the Pacific.
A significant component of the broader investment also supports the entry of the Papua New Guinea Chiefs into the National Rugby League competition in 2028. Australian officials view the expansion as both a sporting milestone and a long-term investment in regional cooperation.
The announcements were made during a series of high-level meetings in Brisbane attended by leaders from Papua New Guinea, Samoa and Tonga. Discussions covered regional security, economic cooperation and the importance of building stronger partnerships throughout the Pacific at a time of increasing geopolitical competition.
Analysts view Australia’s latest initiatives as part of a broader Pacific engagement strategy that combines defence, diplomacy, development and cultural connections. Recent agreements with Fiji, Vanuatu and Papua New Guinea demonstrate Canberra’s focus on becoming the region’s preferred long-term partner.
With security cooperation expanding alongside investments in sport and community development, Australia is seeking to strengthen relationships that extend well beyond defence. The latest commitments signal a long-term vision centred on shared prosperity, regional resilience and closer ties with Pacific nations for decades to come.
