Last week Australia’s foreign and defense ministers, Penny Wong and Richard Marles, travelled to Port Moresby in Papua New Guinea (PNG) to lead Australia’s delegation to the 32nd Australia-Papua New Guinea Ministerial Forum. The meeting was the first since the Pukpuk Treaty, which established PNG’s first formal defense alliance with another country, entered into force in July. The forum focused on turning the treaty’s commitments into practical initiatives for defense cooperation, infrastructure, recruitment, and new technologies.

The headline agreement was a new rotation of Australian defense personnel to PNG. A new combat group of 130 Australian Defense Force (ADF) personnel will be based in PNG on three month rotations. The deployment, known as the Magani Rotation, is intended to deepen military cooperation and increase familiarity between the two forces.

A rotation offers greater advantages over occasional military exercises. It allows personnel to develop more consistent working relationships, become familiar with how each defense force works, and be able to coordinate activities over longer periods. For PNG, it provides greater access to Australian military expertise, while for Australia, it strengthens its ability to operate alongside a neighbor whose geography makes it important to the defense of Australia’s northern approaches.

Alongside this, the two governments also announced a $77 million infrastructure investment fund for the PNG Defense Force. This funding is intended to upgrade PNG’s military facilities to be better able to house, train, and sustain additional personnel.

While the Magani Rotation may be a significant step in advancing the integration of the two defense forces, the more radical idea is the opening up of Australian military recruitment to eligible Papua New Guineans. Applications for the first intake will open on November 16, with an initial pilot program starting in 2027. The first two cohorts will comprise roughly 50 recruits each, with candidates initially sought from the University of Papua New Guinea, Pacific Adventist University, and the University of Technology in Lae. The program is intended to expand over time, although the initial recruitment numbers are modest.

In order to address recruitment shortages, Australia has already expanded ADF recruitment to Australian permanent residents from New Zealand, the United Kingdom, the United States, and Canada who are on the pathway to citizenship. However, the new PNG recruitment is different – it has been established under the Pukpuk Treaty and will allow eligible PNG citizens living in PNG to apply directly.

The initial rationale is similar – to overcome persistent personnel shortages – but it comes with a broader strategic goal. These recruits will train and serve alongside Australians, creating personal, cultural and institutional links as part of a longer-term alliance-building objective. Australia citizenship will be an eventual requirement, but this will come via the conventional permanent residency and citizenship application processes.

At the ministerial forum, Australia and PNG also formalized a partnership covering digital governance, network security, and emerging technologies. The agreement builds on a Telecommunications Blueprint designed to improve PNG’s connectivity and digital infrastructure. For Australia, the partnership has strategic as well as economic significance: secure telecommunications networks are essential to military coordination, government resilience, and the protection of critical infrastructure. It also gives Canberra a greater role in shaping the systems connecting PNG to the outside world, while helping the country strengthen its own digital capabilities.

Australia’s alliance with PNG builds on an existing security program. Since 2023, Canberra has committed AU$200 million under the bilateral security agreement to support PNG’s police and justice institutions, including upgraded training facilities, police helicopters, and a National Forensic Science Center. A second phase of support is planned after the current program ends in 2027. Though separate from the Pukpuk Treaty, this work strengthens PNG’s capacity to maintain internal security and exercise authority across its territory.

The challenge for both Australia and PNG is to turn these commitments into lasting capabilities. Australia is investing serious capital in PNG – including across issues like health and other social infrastructure – and hopes to gain a return for its investment. This return for Australia is PNG’s ability to develop its defense, economic, and social capabilities, and to be better equipped to contribute to its own security and regional stability. This also comes with the caveat that it keeps PNG within Australia’s orbit of influence. For Port Moresby, the objective will be whether its alliance with Australia actually increases PNG sovereign capabilities and improves its development objectives, rather than simply accommodating Australia’s strategic priorities.
