South Australian Treasurer Tom Koutsantonis steps into the spotlight on Thursday to reveal his long-anticipated budget amid the state's finances looking dramatically different from when he delivered a budget almost a decade ago.
In 2026, the treasurer stares down a future debt load approaching $50 billion, driven in part by massive infrastructure projects and rising interest rates. The Liberal opposition claims the annual interest bill of such a debt is topping $3 billion annually.
This year's budget is expected to be another cautious, steady-handed document, shaped by surging operational costs, infrastructure blowouts, and a national economic climate that leaves little room for new spending.
Infrastructure pressures mount
The state's most expensive commitments — including the multibillion-dollar North-South Corridor — remain under intense pressure from rising material costs, labour shortages and construction delays. The Government has already set aside significant contingency funding for overruns, but now faces pressure to rein in those costs too.
Operational costs surge across government
Beyond infrastructure, the government is grappling with sharp increases in day-to-day running costs across health, education, transport and frontline services. Energy prices, wage pressures and service demand have all climbed faster than expected, tightening the budget's room to move.
ABC reporting in 2025 showed health spending was already being swallowed by demand, with $1.7 billion of a $1.9 billion package simply covering rising activity. That trend is expected to continue, with no new funding to fix ramping or help bolster healthcare workers numbers.
Treasury insiders told 7NEWS that this year's budget would focus on "stability over splash", with the government determined to protect its AA+ credit rating and avoid new taxes.
Last year's winners set the benchmark
Last year's budget delivered major investments in SA Police, Whyalla Steel, housing, and health, with SAPOL alone receiving more than $170 million for new officers, equipment and infrastructure. Whyalla secured nearly $2 billion to stabilise steel production, while housing and health saw multi-billion-dollar commitments.
This year, those portfolios are again expected to feature — but with a sharper focus on managing existing commitments, not launching new ones.
Political stakes rise
The Opposition is already accusing the Labor government of having the wrong "priorities" with the states debt levels ballooning, State Liberal Leader Ashton Hurn said it was critical the government demonstrates it's serious about reining in debt.
"Every taxpayer dollar spent is taken from somebody's pocket — money that could pay electricity bills, buy groceries or be saved for a rainy day. That money needs to be respected," Hurn said in a statement. "This government pats itself on the back for budget overspends — but they set the budget. So they are either completely negligent in setting their own targets, or have utter disregard for budget discipline."
What households can expect
A flagship first homebuyer's neighbourhood will be established in Adelaide's north, in the suburb of Munno Para. The Playford Alive precinct is being developed exclusively for first homebuyers and will be fast-tracked with a $50 million budget investment. The project will bring 400 homes to the suburb.
The state government also announced a new initiative for victims of domestic, family and sexual violent to no longer have to pay stamp duty on new or established homes. No costing has been provided.
Last year delivered cheaper student transport, school fee relief and major investments in police. This year, expectations are more modest. Any cost-of-living support is likely to be targeted, not broad-based.
Koutsantonis hands down the budget on Thursday.
