It is 2am on East Arm Wharf, and a crane operator is loading manganese ore onto a bulk carrier bound for China. The crane above the container stacks carries the logo of Shandong Landbridge Group, a private company from the Chinese port city of Rizhao. Fifteen kilometres away at Robertson Barracks, several hundred United States Marines are settled into their dry-season rotation, the latest instalment of a defence partnership that has brought American forces to Darwin every year since 2012. The two facts sit a short drive apart: a commercial wharf under 99-year Chinese lease, and a garrison hosting the forces of Australia's closest ally. For a decade that proximity has driven a Senate inquiry, three separate federal security reviews, an unhappy phone call from a US president to an Australian prime minister, and, in 2025, a bipartisan pledge from Canberra to buy the lease back. None of that changes what happens most nights on the wharf: cargo moves, invoices are raised, and the port that Darwin's economy depends on keeps working, largely indifferent to the argument raging about who should own it.
What the government did
In October 2015, the then Country Liberal Party government of the Northern Territory, led by Chief Minister Adam Giles, granted Shandong Landbridge Group a 99-year lease over the Port of Darwin for $506 million, the result of a competitive tender run through the Territory's Department of Treasury and Finance. The deal covered the East Arm and Fort Hill wharves and handed Landbridge control of day-to-day port operations, though the Territory Government kept a minority ownership interest, reported at around 20 per cent (approx.), in the port's corporate structure.
The lease was struck under the Commonwealth's Asset Recycling Initiative, a scheme the Abbott Government introduced in 2014 to pay states and territories a bonus for privatising public assets and reinvesting the proceeds in new infrastructure. Canberra paid the Northern Territory an incentive of roughly $18.56 million (approx.) for privatising the port, on top of the $506 million Landbridge paid up front. Landbridge separately committed to spend $200 million on port upgrades over the following 25 years.
Because the port was a state or territory asset rather than an operating Australian business, its sale fell outside the formal jurisdiction of the Foreign Investment Review Board (FIRB) under an exemption written into the Foreign Acquisitions and Takeovers Act 1975. The Department of Defence and ASIO examined the transaction informally through 2015 and did not object on security grounds — but Defence itself learned of the completed deal only a few hours before Giles announced it publicly on 13 October 2015, and the federal National Security Committee first discussed the arrangement after the fact, noting there was little the Commonwealth could have done to stop it even had it objected.
The current Northern Territory government, led by Chief Minister Lia Finocchiaro since a landslide election win in August 2024, inherited the lease; it did not write it. Nearly a decade, and one full change of NT government from Labor back to the CLP, separates the 2015 decision from the administration now managing its consequences. Finocchiaro has publicly backed the federal push to return the port to Australian ownership, and in 2026 her Treasurer, Bill Yan, wrote to Landbridge seeking information about its financial position after an independent audit flagged doubt about the company's ability to continue as a going concern.
The strongest case
A loss-making asset, a tight budget, and an open tender
In 2015, the Port of Darwin was a marginal asset. It had run at a loss for years, needed capital upgrades the cash-strapped Territory could not fund, and sat inside a Budget under real pressure once the mining-construction boom faded. Asset recycling was federal orthodoxy at the time, promoted by Canberra as a way to turn dead capital into new roads, schools and hospitals without raising debt or taxes — and $506 million, plus the Commonwealth's incentive payment, was a large sum of money for a jurisdiction of roughly 250,000 people. The tender was open and competitive, Landbridge's bid was comfortably the highest received, and the government of the day did what governments are usually praised for doing before a major sale: it sought advice from the security agencies before signing. Defence and ASIO reviewed the transaction and did not object. A decade on, Darwin Port is no longer loss-making — it reported earnings before interest, tax, depreciation and amortisation of roughly $45 million (approx.) in the 2025 financial year — and Landbridge did deliver on at least part of its promised capital works. Judged only as a piece of state financial management, against the information available in 2015, the deal met the tests usually applied to public asset sales: a competitive process, an independent security clearance, and a price above the port's underlying commercial value.
The evidence
The primary record shows a lease that has been examined for national-security risk more times than almost any other single piece of Australian infrastructure — and cleared every time, until the politics changed.
Set out chronologically, the pattern is stark. Defence and ASIO's informal 2015 assessment found no reason to object. A formal review ordered by the Morrison Government, reporting in 2021 amid rapidly deteriorating relations with Beijing, again found no sufficient national-security ground to unwind the lease. A third review, run by the Department of the Prime Minister and Cabinet in consultation with Defence, Foreign Affairs and Trade, the Attorney-General's Department, Home Affairs, the Office of National Intelligence and ASIO, and finalised in October 2023, reached the same conclusion: existing regulatory and monitoring mechanisms were judged sufficient, and officials stated Australians' safety was not being compromised by the arrangement.
Then, in the lead-up to the May 2025 federal election, both major parties reversed course and promised to return the port to Australian ownership regardless of what the reviews had found. The reversal did not come from a fresh security finding. It followed the 2023 Defence Strategic Review, which reframed Australia's northern base network — including Darwin — as central to the country's ability to project and sustain military force, sharpening political sensitivity to any Chinese commercial presence nearby, even one three separate reviews had already cleared.
The critique: a strategic blind spot
Set against the strategic reality of 2015, the deal still reads as a serious misjudgement — not because the security agencies got their narrow assessment wrong on the facts in front of them, but because the process asked the wrong question. Each review tested a specific transaction: did this deal, on its own, present an unacceptable security risk today? Nobody was ever formally required to ask whether it made sense, as a matter of long-run national strategy, for a private company from a strategic rival to hold a 99-year lease over the only deep-water port serving Australia's most exposed coastline — a coastline that already hosted a growing US military presence and sits at the front of any future contest for maritime access to South-East Asia. A 99-year term outlasts the operational life of most defence planning documents several times over; it locks in an arrangement that will still be running in 2114, regardless of how the strategic environment evolves between now and then. The FIRB exemption that let a state-asset sale bypass formal foreign-investment screening was a drafting gap, not a deliberate national-security judgement — and it meant the one body actually built to weigh sovereign risk in these transactions never formally ruled on the largest single piece of critical port infrastructure in northern Australia. Comparable allied ports, including several in the United States and Britain, are subject to standing restrictions on foreign state-linked ownership of exactly this kind of asset; Australia had no equivalent guardrail for a state-owned port lease in 2015, and the gap was closed only after the fact, through tighter critical-infrastructure legislation passed later in the decade.
The critique: process, and a decade of drift
The process around the announcement compounded the problem. Defence was told of the finished deal only hours before the Northern Territory made it public, leaving no real window for Canberra to raise the transaction with allies before it became fact. When the United States found out, reportedly from press coverage rather than from the Australian government, President Obama raised it directly with Prime Minister Turnbull — a pointed reminder of how badly the sequencing had gone for a partner whose forces train a short drive from the wharf. The episode also helped prompt a 2015–16 Senate inquiry into the foreign-investment framework, which examined the gap that had let the sale proceed without formal FIRB review. That inquiry, and the public argument that followed it, ran in parallel with the port's day-to-day operation for years: cattle, fuel and mineral concentrate kept moving across the wharves while Canberra argued, in successive Parliaments, about whether the original decision could or should be undone.
Three reviews found no security problem. The fourth verdict was political, not intelligence-based.
What followed was close to a decade of institutional indecision. Two further formal reviews upheld the lease; successive federal governments of both colours, and successive Territory governments of both major parties, left it in place; and then an election campaign settled in a matter of months what three formal reviews had spent eight years examining. That is not evidence the earlier reviews were wrong on their own terms. It is evidence that the decision to reverse the deal was ultimately made on political grounds rather than fresh intelligence — which matters, because Australia is now negotiating an exit that could cost more than it ever collected for the asset, from a weaker legal position than if security concerns had been the stated basis from the start. Landbridge's 2026 arbitration claim leans directly on the fact that Canberra's own reviews repeatedly found nothing wrong.
The risk to the future
A costly, contested exit — and a Territory with limited leverage
Unwinding a lease that three official reviews found no legal basis to cancel is now Canberra's problem more than the Northern Territory's, but the Territory is not insulated from the outcome. Landbridge has signalled it may seek compensation approaching $1 billion (approx.) — roughly double what it originally paid — and in 2026 lodged arbitration against Australia at the International Centre for Settlement of Investment Disputes, arguing the forced return breaches Australia's obligations under the China–Australia Free Trade Agreement. If that claim succeeds, or a negotiated buyout lands near the sums reported, Australian taxpayers will pay a large premium to reverse a transaction the security agencies themselves repeatedly cleared, and the diplomatic cost with Australia's second-largest trading partner will be real regardless of the legal outcome. For the Territory, whose net debt is already forecast to exceed $12 billion in 2025-26 and approach $14 billion by 2029 (NT Budget, approx.), a protracted dispute over the port's ownership or value adds uncertainty to the asset that carries the bulk of the Territory's trade, at a time it can least afford it. The lesson for future asset sales is not that foreign investment is inherently unsafe, but that a 99-year strategic lease deserves a strategic-level test, not merely a transaction-level one — and that once a security question becomes a campaign promise, walking it back gets expensive.
