At Darwin's East Arm wharf, cranes are pouring concrete into a 200-metre dry dock large enough to lift an 8,000-tonne warship clean out of the harbour — the Territory's new Ship Lift, budgeted to cost about $850 million to build and around $1.8 billion once decades of maintenance and financing are added in (approx.). It is exactly the kind of asset only a government can build: a bet that Darwin becomes a hub for the Australian Defence Force's build-up in the north, sold to Territorians as jobs, sovereign capability and strategic relevance. But almost none of that $850 million was raised from taxes paid in the Northern Territory. It sits on the same ledger as every school, clinic and police station the Territory runs — a ledger that carried $10.5 billion in audited net debt at the last count, and is still climbing.
That ledger survives on money the Territory does not raise itself. On the government's own figures, Commonwealth funding — chiefly the GST — supplies around 72 per cent of total Territory revenue in 2026-27, with GST alone budgeted to provide roughly 47 per cent of revenue across the four-year budget cycle. Taxation and royalties, the only genuine revenue levers a Territory government controls, make up about 12 per cent. No other Australian jurisdiction runs this reliant on a formula it does not vote on.
What the government did
Lia Finocchiaro's Country Liberal Party (CLP) won a landslide victory at the 24 August 2024 Territory election, taking 17 of 25 Assembly seats from an eight-year Labor government, and Finocchiaro was sworn in as Chief Minister four days later. She inherited a budget already in deficit and a net debt track Labor had set climbing years earlier. What her government has chosen to do with that inheritance is the more relevant question for Territorians today.
Treasurer Bill Yan handed down the CLP's first budget on 13 May 2025, forecasting a $1.31 billion deficit for 2025-26 — more than three times the $410 million Labor had projected before the election — and net debt climbing toward $12.3 billion by the end of that year. Yan was explicit about the government's choice: "Despite the crisis and Labor's failure, now is not the time for austerity," he told the Assembly, favouring growth measures — payroll tax relief for small business, a bigger first home owner grant, cost-of-living rebates — over spending restraint. Budget repair was limited to around $20 million a year in departmental savings targeting consultancies and discretionary spending, a fraction of the deficit it was meant to help close.
A year on, the government's second budget, handed down on 5 May 2026, continued the same approach: the Ship Lift and other capital works kept building, cost-of-living and law-and-order commitments kept flowing, and net debt kept climbing, even as the government pointed to a smaller-than-forecast deficit as evidence of improvement. The Territory's fiscal strategy, reset in the 2025-26 Budget as required under the Fiscal Integrity and Transparency Act, commits the government to eventually stabilising debt — but sets no fixed year by which that must happen.
The strongest case
Running a jurisdiction one-sixth the size of Australia, for 265,000 people, is genuinely expensive
The case for the Northern Territory receiving the largest GST share of any state or territory is not a CLP invention, and Territorians did not choose their circumstances. The Territory covers roughly 1.35 million square kilometres — about one-sixth of the Australian mainland — for an estimated resident population of only about 265,000 people (approx., ABS, Sep-2025). Around 31 per cent of Territorians are Aboriginal or Torres Strait Islander, and close to three-quarters of that population lives in remote or very remote communities (ABS, 2021 Census-based estimate) — places where a clinic visit, a police response or a barge of school supplies costs multiples of the equivalent service in a capital city, simply because of distance. The Commonwealth Grants Commission, the independent statutory body that recommends how the national GST pool is split, assesses exactly this: in its most recent relativity update it specifically cited the Territory's higher-than-average need for community health, family and child protection services, driven by that population profile, as a reason its share rose again. The Territory can also raise only a fraction of the property and land tax revenue per person that larger states can, because it has a comparatively small, low-value property market. Horizontal fiscal equalisation exists precisely to stop a jurisdiction like this being forced to either tax its residents far harder for the same services, or give them visibly worse ones, purely because of where in Australia they happen to live. On the Commission's own published methodology, the Territory is not gaming the system — it is receiving what an independent, needs-based formula says a remote, disadvantaged, sparsely populated jurisdiction requires.
The evidence
The scale of that reliance is visible in the Commission's own numbers. The Territory's GST relativity — the ratio determining its share of the national pool, where 1.00 would be an equal per-capita share — sits at 5.15112 for 2025-26, rising to 5.24149 for 2026-27 (Commonwealth Grants Commission; NT Budget Paper No. 2, 2026-27). That is, and has for years been, the highest relativity of any Australian state or territory; Western Australia, by contrast, is guaranteed a floor of only 0.75 under the 2018 legislation that ended its own GST dispute. On one Commonwealth Treasury estimate, the Territory was already receiving around 466 per cent of its population share of GST by 2017 — the highest ratio in the country (approx.; Commonwealth Treasury, Review of GST Distribution, 2019).
That relativity is not fixed, and it has moved sharply before. In 2015-16 it stood even higher, at 5.57053, before a wave of population and methodology revisions cut it through the following years — a shift the Territory government of the day put at roughly $2 billion in lost GST share over four years, with other estimates as high as $3.4 billion cumulatively between 2017-18 and 2021-22 (approx.; NT Government estimates, cited in Commonwealth Treasury's Review of GST Distribution, 2019). That collapse, layered on an already deteriorating budget, is what forced the then Labor government to establish the Fiscal Strategy Panel in November 2018, chaired by economist John Langoulant. Its interim report that December found the Territory was "borrowing to fund recurrent activities and interest costs" — a textbook description of spending beyond a sustainable structural means. Its final report the following April, A Plan for Budget Repair, made 76 recommendations; the government of the day accepted 68 in full.
The debt trajectory
The Fiscal Strategy Panel's 2018-19 diagnosis has not been cured; on the numbers, it has worsened. The Territory's audited net debt reached $10.543 billion in 2024-25, up $1.525 billion in a single year, and its net debt-to-revenue ratio — a measure of how large the debt is relative to the income available to repay it — rose to 116 per cent, up from 108 per cent the year before (Treasurer's Annual Financial Report 2024-25, audited by the NT Auditor-General, Oct-2025). The 2026-27 Budget Papers, handed down 5 May 2026, put net debt at about $11.35 billion for 2025-26 and forecast it will reach roughly $12.56 billion in 2026-27 and pass $13 billion by 2029-30 — an improvement on the $14 billion the CLP's first budget had forecast for the same year a year earlier, but still a debt track rising every year across the forward estimates.
The cost of servicing that debt is the clearest evidence the trajectory matters. Annual interest payments were running at around $586 million when the CLP handed down its first budget in May 2025; by its second budget a year later, that figure had risen to $679 million for 2025-26, and total interest costs are projected to pass $1 billion a year in 2026-27 (approx.; NT Budget Papers, May-2025 and May-2026). On analysis of the Budget Papers by the Territory outlet NT Independent, that debt load equates to roughly $61,800 for every Territorian in 2026-27, up from about $58,000 the year before — a secondary calculation, but one consistent with the government's own published aggregates. Separately, EY's September 2025 analysis of S&P Global credit data placed the Territory's gross debt burden at around 43 per cent of gross state product, among the highest of any Australian jurisdiction (approx.; EY, Sep-2025, a clearly labelled secondary source).
A billion dollars a year in interest is a billion dollars the Territory does not have for the clinics and classrooms its own GST case rests on.
The dependence trap
None of this erases the legitimate case set out above — the Territory's costs of remoteness and disadvantage are real, and the Commission's formula exists to answer them. But a government receiving the largest GST top-up in the country while its own debt-to-revenue ratio climbs past 116 per cent has effectively made a choice: to keep borrowing rather than bring recurrent spending into line with what even a generously assessed revenue base can sustain. That was the Fiscal Strategy Panel's central warning in 2019, phrased as borrowing "to fund recurrent activities" rather than infrastructure — and the CLP government's own Treasurer has said openly that closing that gap through spending restraint is not this term's priority.
The deeper risk is that the Territory has almost no lever of its own to fall back on if the settlement it depends on ever moves against it. Own-source revenue — the taxes and royalties a Territory government can actually raise or cut — covers only around 12 per cent of the budget, the smallest genuine fiscal capacity of any state or territory. That means the Territory's fiscal fate turns overwhelmingly on two things it does not control: the size of the national GST pool, and the Commonwealth Grants Commission's annual reassessment of what the Territory needs. Both have moved sharply against the Territory before — the relativity swing of the mid-2010s wiped out an estimated $2-3.4 billion in GST share within a few years and helped trigger the last debt crisis. There is no structural reason it could not happen again.
The risk to the future
A formula the Territory doesn't control, and a debt load it can't easily reduce
The Northern Territory is not exposed to a single dramatic cliff-edge, in the way a lapsing guarantee or a legislated sunset clause creates elsewhere in the federation. Its risk is quieter and arguably harder to manage: a structural mismatch between a spending base set by remoteness and disadvantage that is not going away, and a revenue base that is almost entirely outside its own hands. If national GST pool growth slows, if the Commission's methodology shifts against the Territory as it did through the mid-2010s, or if interest rates stay elevated long enough to keep pushing the Territory's own $600-700 million-plus annual interest bill higher still, the Territory has little room to absorb the shock: own-source revenue cannot realistically be doubled, and a net debt-to-revenue ratio already above 116 per cent leaves shrinking headroom to borrow more without credit and market consequences. A Territory that receives the most generous GST settlement of any Australian jurisdiction, and has still let its debt-to-revenue ratio climb every year on the audited record, has used its strongest fiscal advantage to delay a reckoning rather than to avoid one.
