Call her Renee. She rents a three-bedroom house in Adelaide's northern suburbs on a Low Income Health Care Card, raising two primary-school-aged children on a part-time wage topped up by family payments. Her budget has learned a rhythm: the SA Water bill lands on a fixed quarterly schedule she can plan around, the power bill swings harder than she would like each winter, and every February she has to find two lots of sports registration fees before the season starts or her kids sit it out. Renee is a composite, not one named household, but the pattern she stands in for is real and measurable, because South Australia has spent four state budgets building programs aimed squarely at people in her position: a concession payment, a water rebate, vouchers for junior sport, a cheaper student bus pass. What none of those programs can do is lower the price she is being partly compensated for. That gap — between money handed back and the underlying cost of living in a small, gas-exposed, GST-dependent state — is the real story of South Australian cost-of-living policy since Peter Malinauskas became Premier in March 2022.
What the government did
South Australia is Labor's most fiscally constrained mainland jurisdiction: a population of roughly 1.9 million, a shrinking share of GST redistribution as its relative fiscal capacity is assessed to improve, and no mining royalty base to match Western Australia's or Queensland's (ABS, National, state and territory population, Sep-2025 quarter). Its principal lever on cost of living is not price control. Electricity, as in New South Wales and south-east Queensland, is capped under the Australian Energy Regulator's (AER) national Default Market Offer (DMO), not set by the state; South Australia deregulated its own retail electricity and gas prices on 1 February 2013, handing price-setting to the AER and leaving the state's Essential Services Commission of South Australia (ESCOSA) with a monitoring role only (ESCOSA, Energy pricing, accessed 2026). What the state government can decide is who receives help and how much, largely through the Cost of Living Concession (COLC) — a single annual cash payment that in 2016 replaced a patchwork of separate council-rate rebates and energy concessions (SA Government, Cost of living concession, sa.gov.au, accessed 2026).
The Malinauskas government has used four budgets to build on that base. The 2023-24 Budget partnered with the Commonwealth on a $254 million Energy Bill Relief Plan, cutting up to $500 off 2023-24 electricity bills for around 420,000 eligible households and up to $650 for 86,000 small businesses, on top of that year's base COLC of $263.15 for homeowners (SA Department of Treasury and Finance, State Budget 2023-24 — Budget Statement, Jun-2023). It also funded a one-off additional COLC payment of $243.90, paid to more than 210,000 recipients in June 2024 — more than doubling the concession that tenants and Commonwealth Seniors Health Card holders received that year, up from a base of $122 (Premier of South Australia, media release, 2024). From August 2024 that equalisation was made permanent: tenants and Commonwealth Seniors Health Card holders now receive the same ongoing COLC as homeowners, worth up to $255.60 in 2024-25, $261.90 in 2025-26 and $270.60 in 2026-27 (Department of Human Services SA, Cost of Living Concession, 2025). In September 2024 the government layered a separate $64.8 million water and sewerage concession on top, lifting the average concession recipient's relief to $412 a year off their SA Water bill and holding their 2024-25 quarterly increase to about $8, against roughly $21 for an equivalent non-concession household (Premier of South Australia, Additional water concessions to flow to customers, 5-Sep-2024). Two longer-running programs sit alongside the cash concessions: Sports Vouchers, giving every South Australian child from Reception to Year 9 two $100 vouchers a year toward sport, active recreation or music fees, and free 24/7 public transport for the state's roughly 430,000 Seniors Card holders, in place since 1 July 2022 (Office for Recreation, Sport and Racing, Sports Vouchers, accessed 2026). The 2025-26 Budget added a fourth measure, cutting the price of a 28-day student metroCARD pass from $28.60 to $10 — a $20.7 million commitment over four years — and continuing a $200 cut to the public-school "materials and services" charge, worth $96 million over four years (SA Department of Treasury and Finance, State Budget 2025-26 — Cost of Living Support, Jun-2025).
The strongest case
A small state with no price lever has targeted its money at the people who need it most
A fair reading starts with what Adelaide does not control. The DMO is a federally administered price cap; the wholesale gas and electricity shock that drove the 2023-24 spike was an east-coast market event that began before Labor took office, not a state policy failure, and South Australia has neither a mining royalty stream nor a population base anywhere near New South Wales' or Victoria's with which to fund open-ended relief. Given that constraint, the design choices are defensible. Doubling the tenant and Commonwealth Seniors Health Card concession to match homeowners closed a genuine equity gap: renters are, on average, more income-constrained than owner-occupiers, and paying them roughly half as much for the same living costs never had a strong logical basis. Folding the old itemised rebates into a single cash Cost of Living Concession gives recipients the flexibility to direct the money wherever the pressure is greatest that quarter, rather than have the government guess for them. And the smaller, cheaper measures — the sports vouchers, the $10 student pass, the school materials cut — are simple, low-friction, and reach precisely the working families with school-aged children that a concession payment tied to a card tends to miss. None of it lowers the AER's price cap or Adelaide's housing costs, but a government with no lever over either of those things is, on this reading, doing the two things left to it: targeting the money at documented need, and keeping the process simple enough that people actually claim it.
The evidence
The concession side of the ledger shows real, measurable movement. Tenants and Commonwealth Seniors Health Card holders went from a base concession of $122 in 2023-24 to full parity with homeowners — $255.60 that same payment year via the one-off top-up, then $261.90 in 2025-26 — more than doubling the ongoing payment for one of the state's more financially exposed groups in under two years (Department of Human Services SA, 2025; Premier of South Australia, 2024).
Water bills show a structural pattern underneath that relief. ESCOSA's SA Water Regulatory Determination 2024, covering 1 July 2024 to 30 June 2028, set revenue caps roughly 22% higher for water retail and 28% higher for sewerage retail than the prior four-year determination — a structural rise the $64.8 million concession package softens for eligible households but does not reverse (ESCOSA, SA Water Regulatory Determination 2024, 25-Jun-2024).
Electricity shows the same mismatch, on a shorter and more volatile cycle. The AER's residential DMO for South Australia rose 20.8% to 23.9% on 1 July 2023, fell back roughly 3% on 1 July 2024, then rose again by 2.3% to 3.2% on 1 July 2025 (AER, Final and Revised Final Determinations — Default Market Offer prices, 2023-24, 2024-25 and 2025-26). Underneath that regulated cap sits a wholesale market where South Australia has repeatedly recorded the National Electricity Market's most extreme prices: roughly half of the 54 half-hour price spikes above $5,000 per megawatt-hour recorded across the entire NEM in the third quarter of 2024 occurred in South Australia, and the state's average quarterly wholesale price rose to roughly $144 per megawatt-hour that quarter, against Victoria's $50 — despite South Australia sourcing about 74% of its electricity from wind and solar in 2024 (AER, Wholesale electricity market performance report, Dec-2024).
Housing tells the same structural story without any offsetting concession at all. Adelaide's median house price rose by roughly 79% over the five years to November 2025, reaching about $948,000, and the city was ranked the second-least affordable capital in Australia — behind only Sydney — in the most recent Demographia international housing affordability comparison, a clearly-labelled secondary source (CoreLogic-based market data, Nov-2025; Demographia, International Housing Affordability Report). None of the measures above touch that number: they are relief on bills a household already holds, not supply-side measures that change what a house or a rental costs to begin with. The Slow Decay covers South Australia's housing supply response in a companion piece; it sits entirely outside the cost-of-living toolkit examined above.
The critique
Put next to each other, the two halves of the record show a mismatch in both timing and reach. Concessions and rebates are set once a year in a state Budget; the price they are meant to offset is set by a federal regulator on its own annual cycle, and the wholesale market underneath that regulated cap can move within a single quarter, as it did in the third quarter of 2024. A concession fixed in June cannot respond to a wholesale spike in September. The 2023-24 spike is the clearest illustration: the $500 Energy Bill Relief rebate and that year's COLC were both sized against a price shock that had already happened by the time the money arrived, not against what the following quarter's wholesale market would do.
In South Australia, the government can decide who receives help and how much; it cannot decide how much help is needed.
The state's one genuinely structural energy lever — a plan to lower prices by adding dispatchable, state-backed generation rather than simply compensating for the lack of it — did not survive contact with a bigger emergency. The Hydrogen Jobs Plan was meant to deliver 250 megawatts of electrolysers and a 200-megawatt hydrogen-fired power plant near Whyalla, adding dispatchable capacity to a grid that leans on gas peaking plants and batteries to firm an otherwise renewable-heavy supply. On 20 February 2025, as GFG Alliance's Whyalla Steelworks went into administration under an emergency amendment to the Whyalla Steel Works Act 1958, the government deferred the hydrogen project and redirected its roughly $593 million funding package to steelworks support; the Office of Hydrogen Power SA was formally dissolved on 7 May 2025 (SA Government, Hydrogen Jobs Plan deferral announcement, 20-Feb-2025; Office of Hydrogen Power SA dissolution, 7-May-2025). The project this state most needed for a structural answer on power prices became a casualty of an unrelated industrial collapse — a reminder that even a state with a genuine plan to change its cost structure, rather than just cushion it, can be forced to abandon that plan when a bigger fiscal fire needs putting out.
The state's capacity to keep expanding relief is not unlimited either. General government net debt is estimated at $28.8 billion for 2025-26, rising to a budgeted $33.4 billion for 2026-27, as the government funds a run of major infrastructure — the new Women's and Children's Hospital, the North-South Corridor — alongside its cost-of-living commitments (SA Department of Treasury and Finance, Mid-Year Budget Review 2025-26). South Australia also depends more heavily on Commonwealth GST redistribution than most comparably sized states; every dollar of relief the state funds from its own revenue competes directly with the infrastructure and health spending in the same budget, rather than coming from a separate pool.
The risk to the future
Relief renews on a budget cycle; the cost underneath it does not
The clearest risk is a repeat of the pattern already on the record: a wholesale price shock or a fresh DMO rise landing in a year the state's relief has not been resized to match, as happened through 2023. South Australia's grid remains structurally exposed to that risk — heavily reliant on wind and solar, whose output is not free of firming cost, and now short the one dispatchable, state-backed generation project that had been built into its plan, already shelved once to fund an emergency elsewhere. If a similar industrial or fiscal shock recurs while net debt is already climbing toward infrastructure commitments already locked in, the next round of concessions will have less headroom to expand, even as the bills they offset keep moving on their own timetable. Meanwhile Adelaide's housing costs, which no cost-of-living measure in this budget touches, keep compounding independently of any of it. For the next generation of South Australians, the risk is not that targeted relief stops working — it is that it becomes the whole of the state's cost-of-living policy, indefinitely renewed, while the structural costs underneath it are never actually brought down.
