Supply Can’t Catch Up: Understanding Australia’s Housing Shortage in 2026
Australia’s housing shortage persists because builders finish homes far slower than households form. Approvals are climbing, and migration has eased, yet the National Housing Supply and Affordability Council (NHSAC) now expects the 1.2 million-home target to land in the December quarter of 2030, not mid-2029.
Most investors read that as a simple price tailwind. It isn’t. A disciplined property investment group in Australia reads completions, costs and interest rates first. Here’s how.
Are Rising Approvals Actually Fixing the Shortage?
Not yet, and that’s the trap, as most investors get this backwards: they cheer approvals and ignore completions. The ABS counted 205,249 approvals in 2025–26, up 9.2 per cent and the highest since 2020–21. But July slipped 3.6 per cent to 17,687, and an approval is only permission to build. Nobody lives in it.
Look at completions instead. NHSAC says builders have finished 308,000 homes since the Accord began, roughly a quarter of the target, and completions fell 4 per cent over the past 12 months. Meanwhile, net overseas migration still added 292,100 people in the year to March 2026, per the ABS. That’s down from 309,500 the year before, and it’s still a lot of people to house.
What’s Holding Back Completions?
Four pressures keep choking the pipeline, even with a record 244,000 dwellings under construction in the March quarter:
- Costs: house construction costs rose 2 per cent in the June quarter and now sit 51 per cent above pre-pandemic levels, per NHSAC.
- Interest rates: the RBA has lifted the cash rate three times this year to 4.35 per cent, and NHSAC expects some construction to be deferred.
- Tax: Treasury expects the negative gearing and capital gains changes to trim about 35,000 homes from supply, though NHSAC calls the impact modest.
- Capacity: Cotality points to capacity constraints and feasibility challenges that limit any material lift in completions.
Does a Shortage Mean Prices Will Keep Rising?
No, and anyone promising that is selling something. Cotality’s index fell 0.9 per cent in August, the fifth straight monthly drop, leaving national values 3.6 per cent below the March peak. Sydney sits 7.1 per cent off its February high. A shortage cushions a downturn. It doesn’t cancel one.
The upside is quieter. Rents are up 5.7 per cent over 12 months, and the national gross yield of 3.79 per cent is the highest since September 2019. But Cotality notes that yields in the larger capitals remain well below neutral cash flow for most investors. Rising rent isn’t the same as free cash flow. So speak with property investment brokers about your borrowing capacity before you start shopping.
Which States Are Falling Furthest Behind?
Location matters more than the national average suggests. NHSAC’s August report shows Victoria has built 32 per cent of its Accord share and Western Australia 29 per cent, while New South Wales sits at just 21 per cent. Tasmania is on 16 per cent and the Northern Territory on 9 per cent.
Even the leaders are slipping. Rolling 12-month completions fell 9 per cent in both Victoria and Western Australia, and NSW now tracks to March 2032. So don’t buy a state’s headline. Check the completions record of the specific corridor.

Who Feels the Pressure Most?
Households, and the numbers are blunt. NHSAC found a new lease now takes a record 33 per cent of median household income, while servicing a new mortgage takes 45.9 per cent. Saving for that mortgage now takes 11.2 years.
Cotality adds that inflation-adjusted wages have fallen four quarters running. That caps how far rents and prices can run, even in a shortage. Support such as the 5 per cent deposit scheme should cushion the affordable end of the market, but smart investors plan around household budgets, not just supply.
How Should Disciplined Investors Respond?
Treat the gap as a decade-long tailwind, not a trading signal. In practice:
- Buy where infrastructure funding is committed, and check that area’s approvals against its completions.
- Hold a cash buffer, because rates are unlikely to fall quickly.
- Weigh new builds on their merits. Price, rent and land value come first. Tax is the tiebreaker, never the reason.
- Plan for ten years, not ten months. Undersupply plays out across cycles, and it rewards patience.
Can Government Policy Close the Gap?
Governments are trying, as the federal government points to its $47 billion Homes for Australia plan, including $6.3 billion for enabling infrastructure, and NHSAC says every state and territory has introduced supply reforms since the Accord began.
Reform takes years to reach the slab, though. Before the Middle East conflict lifted costs, NHSAC expected about 980,000 homes across the Accord period, well short of 1.2 million. Policy will narrow the gap, not close it, so build your plan on the slower timeline.
Supply Won’t Catch Up, So Your Plan Has To
Stop asking when supply will catch up. Ask whether your plan survives if it doesn’t. Investors who build wealth here buy sound assets, borrow within their means and hold through the cycle.

FAQs:
When will the 1.2 million-home target actually land?
NHSAC’s August report says the December quarter of 2030, one quarter later than it forecast in April. Higher construction costs, rate rises and softer sentiment drove the slip.
How much has migration really slowed?
Net overseas migration was 292,100 in the year to March 2026, down from 309,500, per the ABS. Population still grew 1.4 per cent to 27.9 million, so demand hasn’t disappeared.
What changes for new-build investors from 1 July 2027?
From that date, established homes bought after Budget night can’t use rental losses against wages, while eligible new builds keep negative gearing. Before comparing house and land packages in Australia, confirm how the rules apply to you with an accountant.
How tight are rentals now that prices are falling?
Cotality puts national vacancy at 1.9 per cent, the highest since January 2025 and up from February’s record low of 1.5 per cent. It’s still well below the pre-COVID average of 3.3 per cent, so rentals remain tight.
