Australia locks in Vanuatu security pact, further constraining China's Pacific influence

We are in a permanent contest in the Pacific, a permanent contest for influence.
Australia's Foreign Minister acknowledges the strategic competition with China over influence in Pacific island nations.

In the long arc of Pacific history, where great powers have always sought footholds among scattered islands, Australia and Vanuatu have signed the Nakamal Agreement — named for a traditional gathering place — formalizing a security partnership that quietly but deliberately closes the door to Chinese military and infrastructural expansion in the region. Signed in Canberra by Prime Ministers Albanese and Napat, the treaty forbids foreign military bases on Vanuatuan soil and requires Australian consultation before any third party may engage with the nation's critical infrastructure. It is, at its core, a declaration that the Pacific's security future will be shaped from within the Pacific family — on terms that favour those already at the table.

  • Australia and Vanuatu have signed a binding treaty that explicitly bars foreign military bases and requires Canberra's sign-off on any third-party access to Vanuatu's power grids, ports, and communications networks — a direct constraint on Chinese ambitions.
  • China's measured response, urging that cooperation not 'target any third party,' signals Beijing's clear-eyed recognition that it is the unnamed subject of the agreement's most consequential clauses.
  • Australia is moving fast: just weeks after the Nakamal Agreement, Solomon Islands Prime Minister Wale visited Canberra, and negotiations for a parallel treaty are already underway, even as a secret China-Solomon Islands security pact from 2022 looms as a potential obstacle.
  • Foreign Minister Penny Wong stripped away diplomatic ambiguity entirely, declaring on national television: 'We are in a permanent contest in the Pacific, a permanent contest for influence' — framing the treaty not as a gesture of friendship but as a strategic imperative.
  • Beyond security, the agreement weaves in climate commitments, disaster relief protocols, and renewable energy transitions, giving Australia the posture of a comprehensive partner rather than merely a military counterweight.

On a Monday in late June, Australia and Vanuatu signed the Nakamal Agreement in Canberra — its name drawn from the Vanuatuan word for a traditional meeting place. Prime Ministers Anthony Albanese and Jotham Napat put their names to a document that, on the surface, outlines policing training, maritime support, intelligence sharing, and cyber defence. Beneath that surface lies the agreement's real architecture: no foreign military bases on Vanuatuan soil, no militarisation of critical infrastructure, and a requirement that any third-party engagement with Vanuatu's essential systems — ports, power grids, communications networks — be cleared with Australia first. The target of these provisions is never named, but the effect on China's regional ambitions is unmistakable.

The treaty also commits Vanuatu to prioritising security cooperation within the Pacific Islands Forum — a body where Australia holds considerable influence — rather than pursuing arrangements with distant powers. Australia will provide additional police training and equipment, maritime security support, infrastructure assistance, and cyber defence. Humanitarian aid during natural disasters will flow first from Australia, New Zealand, and France. Climate change is acknowledged as an existential threat, and both nations commit to a renewable energy transition.

Albanese framed the agreement in the language of shared heritage and Pacific kinship, calling it proof that Australia intends to be the region's security partner of choice. When pressed on third-party infrastructure concerns, he acknowledged sovereign rights while making clear the treaty gave Australia certainty on the points that mattered most.

The Nakamal Agreement is one piece of a larger pattern. Weeks earlier, Solomon Islands Prime Minister Matthew Wale visited Canberra, and both leaders agreed to negotiate a similar treaty. Australia pledged an additional $200 million for cyclone recovery and energy support. A complication looms: a secret China-Solomon Islands security pact signed in 2022, whose contents even the current Prime Minister says he has not seen and cannot legally release.

China's foreign ministry urged that regional cooperation not target third parties or serve geopolitical ends. Australia's Foreign Minister Penny Wong offered no such diplomatic cushioning. 'We are in a permanent contest in the Pacific,' she said plainly. The Nakamal Agreement is one brick in what is becoming a deliberate strategic wall — a series of pacts designed to define who shapes the Pacific's future, and who does not.

On a Monday in late June, Australia and Vanuatu signed a treaty designed to reshape the security architecture of the Pacific. The Nakamal Agreement—named after the Vanuatuan word for a traditional meeting place—was inked in Canberra by Prime Minister Anthony Albanese and his Vanuatuan counterpart Jotham Napat. On its surface, it reads as a straightforward security partnership: Australia will train Vanuatu's police, bolster maritime defenses, share intelligence, and strengthen cyber capabilities. But the agreement's real weight lies in what it forbids. No foreign military bases may be established on Vanuatuan soil. No other nation may militarize the country's critical infrastructure. And any third-party engagement with Vanuatu's essential systems—power grids, ports, communications networks—must first be cleared with Australia. The effect is unmistakable: China's ability to expand its footprint in Vanuatu has been substantially constrained.

The agreement also commits Vanuatu to prioritize policing cooperation with members of the Pacific Islands Forum, a regional body where Australia holds considerable sway, rather than pursuing bilateral security arrangements with distant powers. Australia will provide additional training and equipment to the Vanuatu Police Force, greater maritime security support, infrastructure assistance, intelligence sharing, and cyber defense. The pact formalizes Australian support during natural disasters, with Vanuatu agreeing to approach Australia, New Zealand, and France first for humanitarian aid. It also acknowledges climate change as an existential threat to Pacific island nations and commits both countries to transitioning toward renewable energy.

Albanese framed the agreement as a natural expression of shared history and cultural ties between Australia and Vanuatu—connections rooted in Melanesian, South Sea Islander, and First Nations communities. He called it a demonstration of Australia's commitment to being the region's security partner of choice. "We have concluded a balanced agreement that will protect our collective and individual security and our sovereignty," he said, emphasizing that the pact reflected a consensus that security in the Pacific should be a shared responsibility among Pacific Island Forum members. When asked about Australia's concerns regarding third-party investments in Vanuatu's critical infrastructure, Albanese acknowledged the right of all nations to make sovereign decisions about their international engagement. But he made clear that the agreement provided Australia certainty on key points: no foreign military bases, prioritized policing cooperation within the forum, consultation on third-party infrastructure deals, and protection of critical systems from militarization or foreign interference.

The Nakamal Agreement is not an isolated move. Just weeks earlier, Solomon Islands Prime Minister Matthew Wale visited Australia, and the two leaders agreed to negotiate a similar treaty. During that visit, Albanese committed an additional $200 million to support Solomon Islands recovery from Tropical Cyclone Maila and to address ongoing energy challenges. Australia also pledged to study how it could assist with education and skills development. Albanese reiterated his vision: "We want Australia to be the security partner of choice in our region and we want the Pacific family to look after our security in this region." A potential obstacle to an Australia-Solomon Islands treaty is the existing China-Solomon Islands Security Pact, signed in April 2022, whose details remain secret. When Solomon Islands Prime Minister Wale visited Australia, he told media he had not seen a copy of the document and that legislation left by his predecessor made it legally impossible for him to release it.

China's response was measured but pointed. Foreign ministry spokesman Guo Jiakun said China hoped the cooperation would support development and stability in the Pacific Islands region, but cautioned that such cooperation should not target any third party or serve as a pretext for geopolitical competition. The statement reflected Beijing's awareness that Australia is systematically working to limit Chinese influence across the Pacific. Australia's Foreign Minister, Senator Penny Wong, was more direct. Speaking to ABC News Breakfast, she said plainly: "We are in a permanent contest in the Pacific, a permanent contest for influence." That candor captures the stakes. The Nakamal Agreement is one brick in what amounts to a strategic wall—a series of security pacts designed to keep China at arm's length from the Pacific island nations that sit at the crossroads of regional power.

Why does Australia care so much about preventing China from building military bases in Vanuatu? Vanuatu is thousands of kilometers away from Australian territory.

Model

Because geography in the Pacific isn't about distance the way you might think. If China establishes military infrastructure in Vanuatu or other island nations, it gains forward positions that could project power across sea lanes Australia depends on for trade and security. It's about control of the region's future.

Inventor

But Vanuatu is a sovereign nation. Doesn't it have the right to make its own security choices, even if that means working with China?

Model

Technically yes, and Albanese said as much. But the agreement works because Vanuatu requested it. The country faces real threats—climate change, natural disasters, weak institutions. Australia is offering concrete support: police training, maritime security, disaster relief. China's offers have been more opaque. Vanuatu chose the partner offering clarity.

Inventor

What about that secret China-Solomon Islands pact? Why is it secret?

Model

That's the unsettling part. The Solomon Islands Prime Minister himself says he hasn't seen it. His predecessor signed it and locked it away legally. When you can't even read your own country's security agreement, it suggests the arrangement was designed to benefit the signatory more than the nation. That's exactly what Australia is trying to prevent.

Inventor

Is this actually about security, or is it just Australia trying to keep China out of its backyard?

Model

Both. Australia genuinely believes Chinese military presence in the Pacific threatens regional stability. But yes, it's also about influence and competition. Wong said it plainly: this is a permanent contest. The difference is that Australia's offering something tangible—training, money, disaster support—not just exclusion.

Inventor

What happens if China ignores this agreement and tries to invest in Vanuatu's infrastructure anyway?

Model

Then Vanuatu has to consult Australia first. The agreement doesn't give Australia veto power, but it creates friction and transparency. It signals to China that any move will be noticed and discussed. That's often enough to deter action, especially when the island nation has already chosen to align with Australia.
