In Whitlam, one of the newest suburbs cut into the Molonglo Valley, the government's land auctions still draw a crowd: bidders under a marquee watching the price of a bare block climb before a single brick has been laid. Standard house blocks in Canberra's newer estates have been selling for well over $500,000 before construction even starts (Suburban Land Agency sales results, approx., 2025). Ten minutes away in Gungahlin, a family renting a three-bedroom house is paying close to $700 a week — a record high for the city — while Canberra's rental vacancy rate has tightened to below one home in a hundred (Domain Rental Report, March-2026 quarter; SQM Research, 2026). Both households are living inside the same fact: in the Australian Capital Territory, and nowhere else in the country, almost every block of land beneath every one of those homes is owned, at the root of the title, by the government itself.
That is not a figure of speech. Since the Territory was separated from New South Wales in 1911, no residential land in Canberra has ever been freehold. All of it is Crown land, leased to occupiers for terms of up to 99 years — a deliberate design choice, drawing on the land-value ideas of the economist Henry George, written into the law that founded the national capital: "no Crown lands in the Territory shall be sold or disposed of for any estate of freehold" (Seat of Government (Administration) Act 1910, Cth). When the ACT won self-government in December 1988, the Commonwealth's Australian Capital Territory (Planning and Land Management) Act 1988 handed the new Territory government control of releasing that land. The result is a housing market found nowhere else in Australia: the government is not only Canberra's planning regulator, but its only land developer and the seller of every new residential block.
What the government did
The ACT government releases land through a rolling, five-year plan — now called the Housing Supply and Land Release Program and previously the Indicative Land Release Program — published by the City and Environment Directorate and delivered by the Suburban Land Agency (SLA), a Territory-owned corporation created under the City Renewal Authority and Suburban Land Agency Act 2017 to take over the land-development role of the former Land Development Agency. The SLA prepares blocks — greenfield estates such as Whitlam and Jacka, and infill sites closer to the centre — and sells them by public auction, ballot or direct tender. It is, in effect, both the master planner deciding how many homes Canberra gets each year and the vendor collecting the proceeds.
The 2025-26 ACT Budget set out the largest land release program the Territory has published: land intended to support almost 26,000 new homes over five years, with 3,184 dwellings targeted for release in 2025-26 alone, and a minimum of 20 per cent of new releases now reserved for affordable and social housing, up from 15 per cent previously (ACT Budget 2025-26, Treasury; Property Council of Australia, 2025-26 ACT Budget Analysis). The Barr government has also struck a deal with the Commonwealth worth $250 million to help deliver about 4,900 homes in the Territory, including more than 1,700 reserved for first home buyers (CMTEDD media release, 2026), on top of an existing commitment to add 5,000 public, community and affordable rental dwellings by 2030.
The strongest case
Planned growth beats land banked by private speculators
The government's defence of the monopoly model is coherent, and worth stating in full before it is tested. A single public land developer can stage new suburbs so that roads, schools, water, power and public transport arrive with the houses, rather than years behind them — something private, competing developers holding scattered parcels have less incentive to coordinate. The Suburban Land Agency's own account of its role stresses exactly this: land release is planned "in a coordinated and sustainable way" across greenfield growth areas such as Molonglo and infill precincts, giving builders certainty about supply rather than a scramble of unrelated private releases (Suburban Land Agency, "What we do", 2026). Because the Territory owns the land outright, it can also require a fixed share of every release to go to affordable, public and community housing — the 20 per cent floor set in the 2025-26 Budget — a lever no state government has over private land it does not own.
The revenue argument is real, too. Land sale proceeds and the related general rates base are among the largest single contributors to the ACT's own-source revenue — general rates revenue alone is budgeted at $910.3 million in 2025-26, up from $813.5 million the year before (ACT Budget 2025-26, Aggregate Land Value paper, Treasury) — and the government's case is that this revenue funds the schools, health services and transport links that make new suburbs liveable rather than merely profitable. On this reading, an orderly, government-controlled land supply is not a device to inflate prices but the mechanism preventing 1980s-style leapfrog sprawl on one hand and underfunded infrastructure on the other. It is a genuine trade-off, not a fig leaf, and any critique of the model has to reckon with the alternative: a Territory with no coordinated land supply and no lever over affordable-housing quotas at all.
The evidence
Set against that case, the record the ACT government has built for itself is mixed at best. Canberra's median house value reached $1,035,828 in July 2026, with the median unit at $597,430 and the combined dwelling median at $885,254 — among the highest in the country outside Sydney (approx.) (Cotality Home Value Index, Jul-2026). Median asking rent for a house sat at a record $700 a week over the March-2026 quarter, with units at a record $580, and the rental vacancy rate tightened to 0.8 per cent — the lowest since mid-2022 — even as rents stopped climbing further, suggesting affordability rather than raw supply is now the binding constraint (Domain Rental Report, Mar-2026 quarter).
The Suburban Land Agency has also missed its own release targets in successive years. In 2024-25 it targeted land release sufficient for 608 public, community and affordable dwellings, but delivered only 451 — a shortfall of 157 — while its income, driven largely by land sales, came in around $50 million below budget and more than $60 million below the year before (SLA Annual Report 2024-25; Canberra Times reporting, 2025). That followed an earlier shortfall in 2022-23, when land was released for only 203 dwellings against a target of 314. The pattern is not new: an ACT Auditor-General performance audit reported in 2020 found that fewer than one in five of the affordable-housing blocks the SLA had released had actually been purchased, and that the mix on offer — mostly one and two-bedroom units — did not match the three-bedroom homes most buyers on the affordable-housing list were seeking (ACT Auditor-General, performance audit reported Jun-2020).
The financial pressure runs in both directions, which complicates any simple "government profiteering" story. In an earlier period, reported around 2019, the SLA sought a $50 million loan amid what internal reporting described as a "dire" financial position; in 2024-25, its revenue again came in well short of budget, on a mix of softer sales and slower settlements (Canberra Times reporting on SLA finances, approx. 2019 and 2025). Former ACT Treasury official Khalid Ahmed has separately calculated that the number of blocks released to market fell substantially over the 2010s even as Canberra's population kept growing, and that as supply tightened, profit margins on land sales rose — analysis that then-Chief Minister Jon Stanhope, who led the Territory's own Labor government from 2001 to 2011, later used publicly to accuse his Labor successors of "price gouging" on land (Canberra Times reporting of Ahmed/Stanhope analysis, approx. 2019).
A former Labor Chief Minister has said the government's profit margin on Canberra land sales is matched by few operators besides outlaw motorcycle gangs — and the Suburban Land Agency has still fallen short of its own housing-release targets in two of the last three years.
The critique
The structural problem is not that the ACT government releases land in stages — most of the steelman case for orderly, serviced release is sound. It is that the same entity decides how much new land enters the market, sets the reserve prices, and then books the proceeds as revenue its own Budget depends on. No private developer anywhere else in Australia can restrict a metropolitan area's entire land supply; the ACT government can, and its Budget position benefits when it does. That is not proof of a deliberate strategy to inflate prices — nothing in the public record establishes intent — but it is a conflict of interest the government's own record has not resolved. An ACT Auditor-General report as far back as February 2011, Residential Land Supply and Development, examined exactly this question of whether the Territory's land release systems reliably matched supply to demand; more than a decade on, the Auditor-General's Performance Audit Program 2026-27 still lists a fresh examination of the SLA's effectiveness in developing and releasing residential land as a live candidate for audit — itself a sign the question was never conclusively settled (ACT Auditor-General, Report No. 2 of 2011; Performance Audit Program 2026-27).
The evidence that does exist points the same way from three different angles. First, the SLA has undershot its own publicly stated release targets in at least two of the past three financial years, for the segment of the market — public, community and affordable housing — the government says it prioritises most. Second, the 2020 Auditor-General finding that most affordable blocks released did not match what affordable-housing buyers actually needed suggests the program has, at times, optimised for moving land off the books rather than for housing the people it was designed for. Third, the swing between a $50 million SLA loan shortfall in one period and a $50 million-plus revenue miss in another shows a revenue model that is neither consistently generous to the Budget nor consistently gentle on buyers — it simply concentrates both the upside and the downside of the Canberra housing market inside one government agency, with no private competitor to test whether its prices and its pace of release are actually efficient.
The risk to the future
A single seller cannot easily be both landlord and referee
If the ACT government continues to be, simultaneously, Canberra's sole supplier of new residential land, its planning regulator, and a Budget that leans on land-related revenue for hundreds of millions of dollars a year, the underlying conflict of interest will not resolve itself. Every year the Suburban Land Agency misses its own release targets for affordable and social housing, as it has in two of the last three years, the gap is filled by fewer entry points into home ownership for the nurses, teachers and young public servants who keep the Territory running — even as median house values sit above $1 million and rents sit at record highs. Independent scrutiny matters more, not less, in a market with only one seller; the fact that the Auditor-General is still weighing a fresh audit of the SLA's effectiveness in 2026-27, a decade and a half after its last major look at residential land supply, suggests that scrutiny has not kept pace with the stakes.
The fiscal risk cuts the other way, too. Because the Budget has grown reliant on land sales and land-based rates revenue, any government response that meaningfully increased supply and cooled prices would also cool the revenue line the Territory depends on to fund services — a structural disincentive to fully solve the affordability problem it is uniquely placed to fix. Until the ACT separates the roles of land seller and land regulator more clearly, or subjects the SLA's release decisions to genuinely independent, real-time scrutiny, Canberrans have limited assurance that the pace of new housing reflects what the market needs rather than what the Budget can absorb.
