The Supply Side of the Answer
The "build more homes" consensus is half right. The other half is doing the work the slogan was supposed to do.
Supply is the right answer to the wrong question.
The supply argument on housing is correct. This needs saying clearly, because the people making it have spent a decade being told they were heartless, market-fundamentalist, or both, and the people making it the loudest right now are economists and central bankers who have stopped caring about being liked.
Australia has not built enough houses. This is a measured statement against a measured target. The National Housing Accord — agreed by all levels of government in August 2023 — set the goal at 1.2 million new well-located homes between July 2024 and June 2029. As of the National Housing Supply and Affordability Council's first quarterly report (March 2026), 219,000 dwellings had been completed across the first five quarters. That is 18% of the target with 25% of the period elapsed. The Council itself, in its 2025 State of the Housing System, forecasts only 938,000 completions across the full Accord window: a shortfall of 262,000, or roughly 22%. Productivity Commission Chair Danielle Wood, speaking on the ABC's That's Business podcast in April, was direct: the target "is not going to be met."
The Council is right about why. Approval timeframes have stretched. Construction productivity has fallen 12% over thirty years, even after adjusting for larger and higher-quality homes. Project feasibility — the simple test of whether a building can be sold for more than it costs to build — has collapsed in many higher-density markets. Public infrastructure has crowded out private residential construction; the NSW Productivity and Equality Commission, under Peter Achterstraat, found in August 2024 that NSW completions had fallen from around 75,000 in 2018 to just over 45,000 by March 2024, while the average development application timeline expanded from 22 months in 2015 to 30 months in 2023. Planning regimes are real costs; design rules unrelated to safety are real frictions. The economists pointing at these things are not making them up.
So when a government minister says we need to build more houses, the sentence is correct.
It is also incomplete in a way that does specific political work.
It does not say what kind of homes. The Council's own forecast has detached houses constituting nearly two-thirds of new supply through 2029. Higher-density dwellings — the kind that make for cities people can afford to live in close to work — are projected to remain at roughly half their 2017 peak. A 1.2 million target met overwhelmingly by detached houses on the urban fringe is a different policy from a 1.2 million target met by mid-rise apartments near transit. The slogan does not distinguish between them. The shortfall does.
It does not say where. The Council's table of state-by-state expected completion dates has Tasmania finishing its share in September 2033 and the Northern Territory after 2034. NSW is forecast to complete its share by June 2031, two years late. Sydney, where the demand pressure is strongest, is forecast to deliver less than half its target. We are building 1.2 million homes is a national number; the experienced number is a postcode.
It does not say who. The construction industry has been at capacity for several years. Skilled labour is scarce. Public infrastructure pipelines bid against residential. Build more is a sentence; who is going to build it, with whose tools, on which sites, against which competing demands for the same workers is a policy. One can be announced. The other has to be built.
And it does not say how fast. The Institute of Public Affairs ran the numbers on February 2026 approvals: 19,022 dwellings approved nationally, 978 short of the 20,000 monthly minimum the Accord requires. Cumulative approvals since July 2024 stood at 322,338, leaving a 77,662 shortfall against the period's pro-rata target. The Accord has never once hit its minimum monthly target. There are forty-five months left until June 2029. Recovering the missed approvals while continuing to hit the monthly minimum — itself never achieved — would require an additional four months of full-target approvals stacked on top of every remaining month delivering its full ration. This is not an aggressive plan. This is a wish list arriving in the post.
The supply argument and the supply slogan are doing different things. The argument identifies the binding constraint — Australia builds too few homes, slowly, in the wrong places, at falling productivity — and points at where pressure should be applied. The slogan takes the argument and uses it to say: we are doing the thing the argument calls for. Then the figures arrive — 18% built, 25% of the period gone, 12% productivity decline over thirty years, 30-month approval timelines — and the slogan is asked to do work it cannot do.
This is the move worth watching. Supply arrived in Australian housing politics as a corrective: a reminder that you cannot tax-credit your way out of a constraint that is, fundamentally, about how many things get built. Used that way, it is a useful word. Used as the entire content of a policy — we hear you, we are building more homes — it is doing the opposite of what the economists who introduced it wanted. They wanted the question opened. The slogan closes it.
The Productivity Commission's Chair has said in public that the target will not be met. The Council's own modelling agrees. The figures are not contested. What is being defended is not the supply argument, which is sound. What is being defended is the use of the supply argument as proof that someone is doing something — that something being, primarily, the use of the supply argument.
A useful question for the next election: which homes, where, by whom, by when. The supply slogan does not answer any of these. The supply argument does, when anyone is asked.
