The housing shortfall is now measurable. What it means for NSW buyers
Sydney values are 7.1 per cent below their February peak while Australia has fallen about 124,000 homes behind its National Housing Accord target and NSW is building at roughly half its required pace. Falling prices and deepening undersupply in the same market, and what each half means for a buyer deciding whether to move now or wait.
Two sets of numbers landed over the past week that sit oddly next to each other. Sydney dwelling values are 7.1 per cent below their February peak (Cotality, September 2026), auction volumes have thinned and clearance rates are scraping along under 50 per cent. At the same time, new figures show Australia is falling further behind its national housing construction target, and NSW is building at roughly half the pace its own share of that target requires.
Falling prices and deepening undersupply, at the same time, in the same market. For a buyer deciding whether to move now or wait, it helps to understand both halves.
What the National Housing Accord is
The National Housing Accord is the agreement between the federal government, the states and territories to build 1.2 million new, well-located homes over five years from mid-2024 to mid-2029. Each state carries a share of the target. NSW’s share is 377,000 new homes by July 2029, which works out to a required pace of more than 88,000 completions a year (Property Council of Australia, July 2026).
The Accord is a supply target, not a price policy. Its relevance to buyers is simple: how much new housing actually gets built over the next three years shapes the level of competition for the existing stock, both to buy and to rent.
How far behind the target is
At the national level, 47,170 homes were completed in the June 2026 quarter (Australian Bureau of Statistics, October 2026). That brought total completions over the first two years of the Accord to 355,820, against roughly 480,000 needed to be on track, a shortfall of about 124,000 homes. The Urban Development Institute of Australia projects that the gap could grow to around 310,000 homes by the end of the Accord period if current conditions persist (UDIA, October 2026).
NSW is running at roughly half its required pace. Completions in the 12 months to March 2026 were 44,700, against the 88,000-plus a year the state’s 377,000-home target implies. The March 2026 quarter was weaker again, with 10,227 completions, down 15 per cent on the previous quarter, and commencements fell 29 per cent to 11,841 (Property Council of Australia, July 2026). Commencements matter because they are the completions of 2027 and 2028. A falling commencement number today locks in a thin delivery pipeline for the next two years, whatever happens to approvals in the meantime.
The UDIA points to the mechanics behind the gap: it estimates that financing capacity for new projects and buyers’ spending power have each been eroded by about 10 per cent through the rate cycle (UDIA, October 2026). Projects that were viable at a 3.60 per cent cash rate are marginal at 4.60 per cent, and builders do not start marginal projects.
Why prices are falling anyway
If the state is short of homes, why are values down 7.1 per cent from the peak? Because in the short run, prices are set by borrowing capacity and sentiment, not by the dwelling count. The Reserve Bank of Australia lifted the cash rate to 4.60 per cent on 29 September 2026, the fourth increase in eight months, and every rise cuts what buyers can borrow and what they are willing to pay. Advertised stock is up roughly 24 per cent on a year ago (Cotality, September 2026), so more sellers are competing for fewer funded buyers.
Supply shortfalls work on a longer clock. They show up first in the rental market, where national vacancy is 1.9 per cent and rents are up 5.7 per cent year on year (Cotality, September 2026), and then in price competition once borrowing capacity recovers. The current downturn and the structural shortage are not in contradiction. They are two different timeframes.

Common questions
What is the National Housing Accord target for NSW?
NSW's share of the National Housing Accord is 377,000 new homes between mid-2024 and July 2029, a required pace of more than 88,000 completions a year. In the 12 months to March 2026 the state completed 44,700 homes, roughly half the required rate, and the March 2026 quarter saw 10,227 completions and 11,841 commencements, both down on the previous quarter (Property Council of Australia, July 2026).
How far behind is Australia on the 1.2 million homes target?
Completions over the first two years of the Accord totalled 355,820 nationally, against roughly 480,000 needed to be on track, a gap of about 124,000 homes (Australian Bureau of Statistics, October 2026). The Urban Development Institute of Australia projects the shortfall could reach around 310,000 homes by mid-2029 if current conditions persist (UDIA, October 2026).
If housing is undersupplied, why are Sydney prices falling?
Short-run prices follow borrowing capacity and sentiment. The cash rate has risen four times in eight months to 4.60 per cent (Reserve Bank of Australia, 29 September 2026), cutting what buyers can borrow, while advertised stock is up about 24 per cent on a year ago (Cotality, September 2026). Undersupply works on a longer clock, showing up first in rents and vacancy rather than prices.
Does the shortfall mean buyers should hurry?
Not by itself. The shortfall is a medium-term pressure, not a reason to skip due diligence in a falling market. It does mean the current combination of price falls and wide choice may not persist once borrowing capacity recovers. Whether to act now depends on your finance position, which is a conversation for your broker or adviser. Foleo does not give financial, credit or tax advice.
Where is the undersupply most acute in NSW?
Completions and commencements are reported statewide (Property Council of Australia, July 2026), but delivery varies by council area and dwelling type, and that detail is not in the headline figures. Suburb-level pipeline analysis, matched against population growth and rental vacancy, is the kind of work an investor-specialist buyer's agent does when building an area shortlist.
