Australia is falling behind on housing supply
Annual completions versus the National Housing Accord target of 240,000 dwellings per year (1.2 million over 5 years).
Every year, Australia falls tens of thousands of homes short
The red zone is the gap between what we build and the 240,000/yr National Housing Accord target. It hasn't closed once this decade — and forecasts show it widening again by 2028–29.

The shortfall compounds — every year we dig the hole deeper
Cumulative gap between target and delivery. By 2028–29, Australia will be roughly 498,000 homes behind where the Accord said we needed to be.
Cumulative shortfall = sum of (240,000 − annual completions) over the period shown.
