Australia and Vanuatu Sign Pact Expanding Canberra’s Pacific Role

Australia and Vanuatu signed the Nakamal development and security agreement on June 29, 2026, expanding Australia’s role in infrastructure, security and policing arrangements in the Pacific island country.

Under the agreement, Vanuatu will consult Australia on third-party investment in critical infrastructure. The provision gives Canberra a formal role when outside investors seek involvement in projects considered important to Vanuatu’s infrastructure network.

The agreement also confirms Australia as Vanuatu’s preferred security and policing partner. It links cooperation on infrastructure investment with a broader security relationship between the two governments.

What the pact provides

The consultation requirement applies to investment by third parties in Vanuatu’s critical infrastructure. The agreement therefore creates a process for Australia to be involved in discussions about outside participation in that sector.

The reported terms do not describe the arrangement as a military alliance. They establish Australia as Vanuatu’s preferred partner for security and policing and give Canberra a consultation role on third-party infrastructure investment.

Australia had previously announced A$500 million over 10 years for the agreement. The funding commitment is intended to support the wider partnership, alongside the security and infrastructure provisions set out in the pact.

The agreement’s full implementation timetable and the precise legal scope of Australia’s consultation power were not detailed in the reported announcement. The confirmed changes are the consultation requirement for third-party investment in critical infrastructure and Australia’s preferred-partner status in security and policing.

A delayed agreement amid regional competition

The pact had been delayed for months after Vanuatu raised concerns that its investment provisions could limit investment from other countries. The signing shows that the two governments reached an agreement on the delayed arrangement, although it does not establish how every provision will operate in practice.

The deal comes as Australia seeks to increase its influence across the Pacific amid competition with China for regional relationships. Infrastructure and security cooperation are important parts of that wider contest, particularly in Pacific island countries where outside governments are seeking stronger partnerships.

For Vanuatu, the agreement connects Australian funding and security cooperation with a formal consultation process over outside infrastructure investment. For Australia, it establishes a defined role in decisions involving a sector with both economic and security significance.

The pact does not, in the reported terms, exclude investment from any particular country. Nor do the reported terms establish that Chinese investment is barred. Instead, the agreement gives Australia a consultation role while confirming Canberra’s preferred position in Vanuatu’s security and policing cooperation.

The signing marks the completion of a process that had been held up by Vanuatu’s concerns about limiting other investment. The next practical question is how the governments will apply the consultation arrangement and distribute the announced funding over the agreement’s 10-year period.
