US Delegation Urges Australia to End Darwin Port Lease, Raise Defense Spending

The American pressure signals that the 99-year Chinese-linked lease on a strategically positioned Australian port remains a live diplomatic friction point under the current US administration.

A United States congressional delegation visiting Canberra has formally pressed Australian officials to terminate a long-running lease on the Port of Darwin held by a Chinese-linked company and to increase overall defense expenditure, according to The Age.

Republican congressman Michael McCaul, co-chair of the US-Australia relations group in the US Congress, described the Darwin lease as a security concern following the delegation's visit. "It's an issue," McCaul said, according to The Age report published on September 16, 2026.

The Port of Darwin lease was granted in 2015 by the Northern Territory government to Landbridge Group, a Chinese company with reported ties to the Chinese Communist Party. The lease runs for 99 years. The port sits near Darwin, a city that hosts rotational deployments of US Marines under an arrangement established in 2011 under the Obama administration's Asia-Pacific rebalance strategy.

The proximity of a Chinese-linked commercial operator to a US military rotation base has drawn concern from American officials across multiple administrations. As far back as 2015, then-US President Barack Obama said he would have preferred more advance notice before the lease was signed, according to prior reporting by Australian Broadcasting Corporation.

Australia's federal government has reviewed the Darwin lease on prior occasions. The Australian Foreign Investment Review Board examined the deal, and successive Australian governments have declined to move to cancel it, citing legal and contractual complexities. The current status of any formal review process initiated by the Albanese or subsequent government is not confirmed in the available source material.

The US delegation's defense spending request reflects a broader pattern of American pressure on treaty allies to meet or exceed the NATO guideline of two percent of gross domestic product allocated to defense. Australia's current defense budget is approximately 2.1 percent of GDP, according to the Australian government's 2024 defense budget documentation, placing it marginally above that threshold, though US officials have at times argued for higher spending given the Indo-Pacific security environment.

The Darwin pressure comes at a moment when US-Germany defense talks are also focused on alliance burden-sharing. Pentagon chief Pete Hegseth met with German Defense Minister Boris Pistorius in Washington, DC to discuss what officials described as "NATO 3.0" and broader defense cooperation, according to Anatolia Agency. The parallel conversations suggest a coordinated US effort to realign alliance defense commitments across both the Atlantic and Indo-Pacific theaters.

The Darwin port issue is also relevant to the AUKUS trilateral security partnership among Australia, the United Kingdom, and the United States, announced in September 2021. That agreement includes provisions for Australian acquisition of nuclear-powered submarines and deeper integration of Australian defense infrastructure with US and UK operational requirements. Critics of the Darwin lease have argued it creates an inconsistency within AUKUS commitments, though no formal AUKUS document reviewed publicly addresses the Darwin situation by name.

What remains unknown is whether the Australian government has received a formal written request from the US side in connection with this delegation visit, or whether the pressure has remained at the level of oral diplomatic exchange. A formal written request, if it exists, would likely require disclosure under Australian parliamentary transparency rules or through a freedom of information process.

Landbridge Group has previously stated that its operations at Darwin are purely commercial and do not involve any intelligence or security activities. The company has not issued a public statement in response to the most recent US pressure as of the publication date of the source report.

The delegation's visit and McCaul's comments add congressional weight to executive-branch concerns that have been expressed periodically since 2015. Whether the Australian government will act on the request, and on what timeline, has not been stated publicly by Australian officials as of September 16, 2026.
