How Darwin Port ended up under a Chinese lease — and why it still hasn't been resolved

Cargo ships are still loading and unloading at Darwin Port's Fort Hill Wharf this week, and Landbridge Group — the Shandong-based conglomerate that holds a 99-year lease over the facility — is still collecting fees. That is the operating reality nearly a decade after a deal that has become one of the most scrutinised infrastructure transactions in Australian history, and one that successive federal governments have so far failed to fully unwind.

The scrutiny matters right now because the AUKUS submarine pathway is entering its most consequential phase. The first rotational presence of US Virginia-class submarines is expected to begin moving through HMAS Cuyper and the broader Darwin Harbour precinct by the late 2020s. Defence planners in Russell Offices have been explicit, in budget submissions and Senate estimates hearings, that port access and security arrangements in Darwin are inseparable from those commitments. A commercially operated wharf, leased to a company with documented links to the Chinese Communist Party, sitting adjacent to the most significant allied military build-up in the Top End's history, is not an abstract concern.

The 2015 deal and the decade of second-guessing

The Northern Territory government signed the lease in October 2015. The Country Liberal Party administration, led at the time by Adam Giles, transferred a 99-year operating licence over the Darwin Port Corporation's commercial operations to Landbridge for $506 million. The sale went through without a Foreign Investment Review Board assessment — FIRB rules at the time did not capture port leases of that structure — and without any formal national security vetting process. The Defence Department was not formally consulted before the contract was executed, a fact that emerged in subsequent Senate inquiries and that has shaped every policy debate about critical infrastructure since.

The Obama administration expressed concern directly to Canberra within weeks. The US Pacific Command flagged the lease to Australian counterparts, noting Darwin's role hosting Marine Rotational Force – Darwin, which had been operating out of Robertson Barracks in Palmerston since 2012. By 2016, the federal government had begun a post-mortem that eventually produced the Security of Critical Infrastructure Act 2018 and its 2021 amendments — legislation that now gives the government powers it simply did not have when Landbridge signed on the dotted line.

The NT Labor government that replaced the CLP in 2016 inherited both the revenue from the deal and the political liability. Darwin Waterfront precinct, Stokes Hill Wharf and the surrounding hospitality strip have continued operating commercially through all of this, largely insulated from the regulatory argument playing out in federal corridors. But the freight terminals at East Arm Port — where bulk mineral exports, live cattle shipments and general cargo move through — are directly under the Landbridge operating agreement, and that is where the tension sits.

Why buying it back is harder than it sounds

The federal government announced a review of the lease under the critical infrastructure laws in 2021. That review has never produced a public outcome. Landbridge has consistently maintained it operates the port commercially and transparently, and its Australian subsidiary has met its licence obligations. The complication for any forced divestiture is the valuation. Infrastructure analysts have estimated the lease buyback could cost the Commonwealth between $1.5 billion and $2.5 billion, depending on how future revenue streams and remaining lease tenure are assessed — Landbridge paid $506 million in 2015 for what is now a more strategically valuable asset in a tighter market.

The NT government, which receives a dividend stream from the original sale proceeds, has a direct financial interest in how any transition is structured. Chief Minister Eva Lawler's administration has called for federal funding certainty before committing to any renegotiated arrangement, and Territory officials have been in discussions with the Department of Infrastructure through much of 2025 and into this year.

The practical upshot for businesses operating out of the East Arm Logistics Precinct on the Stuart Highway is that freight operations are stable and not under immediate threat of disruption. But the regulatory question is not going away. AUKUS submarine rotation timelines and the expanded US Marine presence mean that by 2028 at the latest, Canberra will need a settled answer about who controls the infrastructure surrounding Darwin Harbour — and the clock is running faster than the negotiations.
