NAB Just Issued Major Warning for Australian Property. Most People Aren’t Ready For What Comes Next
By: Niro Thambipillay
August 31, 2026
NAB expects Australian capital-city property prices to fall about 7% from peak to trough, with the adjustment potentially continuing through late 2026. That sounds severe in a headline, but the bank’s forecast is smaller than Australia’s 2022 to 2023 downturn and does not describe every city or suburb.
In this article, Niro Thambipillay examines NAB’s warning, the lending and listings data behind the slowdown, the housing-supply constraints supporting prices, and the early signals that buyer demand may already be returning.
TL;DR
NAB is forecasting a roughly 7% capital-city decline, led by Sydney and Melbourne, while growth in Brisbane, Adelaide and Perth is expected to cool rather than reverse. Buyer uncertainty, not distressed selling, is driving the slowdown. Listings remain below average, mortgage arrears are under 1%, housing construction is falling short, and early broker inquiries suggest demand could strengthen before the official data shows it.
Key Takeaways
- NAB forecasts a 7% correction: smaller than the 8.1% capital-city fall recorded from April 2022 to January 2023.
- Sydney and Melbourne face the greatest weakness: NAB expects growth to cool, not necessarily turn negative, in several smaller capitals.
- Buyers have stepped back: new home lending fell 5.4% in the June quarter, including an 8.6% investor decline.
- Forced selling remains limited: listings are below their five-year average and mortgage arrears remain under 1%.
- Supply is still the long-term pressure: approvals are below the monthly target while construction costs and builder failures restrict new housing.
What Did NAB Warn About?
NAB says Australian capital-city dwelling prices could fall about 7% from peak to trough. Its economists believe the downturn is roughly one-third complete in both time and price terms, with the adjustment potentially taking the better part of a year.
1. NAB’s Forecast Is a Correction, Not a Historic Collapse
Prices had already fallen about 3% during 2026 when NAB issued its forecast. On a $1 million property, that represents roughly $30,000, leaving a value near $970,000.
The comparison matters. Australia’s largest capital-city correction in the previous 40 years ran from April 2022 to January 2023, when capital-city prices fell 8.1% and national prices fell 7.5%. NAB’s 7% forecast would not exceed that downturn. Sydney and parts of Melbourne are expected to record the largest falls, while Adelaide, Perth and Brisbane may continue growing at a slower rate.
2. Buyers Are Hesitating, but Sellers Are Not Being Forced Out
New home loans fell 5.4% in the June quarter. Investor lending was down 8.6%, owner-occupier lending fell 3.3%, and first-home-buyer lending declined 2.9%. The slowdown is therefore broader than investor tax changes alone.
The other side of the market does not resemble distress. New listings are 7% below their five-year average, Sydney listings are 14% below average, and mortgage arrears remain under 1%, around their long-term norm. Those figures do not show the conditions a genuine Australian property crash would need. They show nervous buyers waiting for clarity.
3. Rate Certainty Could Bring Buyers Back Before a Rate Cut
Barrenjoey expects the downturn to run toward late 2026, followed by price stabilisation and possible appreciation in early 2027. If fewer owners list during the spring selling season, reduced supply could support clearance rates and prices.
Ray White chief economist Nerida Conisbee describes three phases: uncertainty while buyers wait, renewed activity once another rate rise looks unlikely, and a stronger recovery when the RBA eventually cuts. The market may not need a cut to improve. Greater certainty alone could bring buyers back.
4. Australia Is Still Not Building Enough Homes
Dwelling approvals have trended lower since 2017. June recorded about 18,300 approvals, below the roughly 20,000 per month needed to meet the government’s housing target, before accounting for the existing shortfall.
NAB’s survey found 77% of property professionals now regard construction costs as the main barrier to new projects, up from 65% in the previous quarter. The Bathla Group’s voluntary administration reportedly left as many as 15,000 Western Sydney homes in limbo, while 1,522 construction firms failed in New South Wales during the last financial year.
With population still growing, constrained construction limits how quickly housing supply can respond. That places renewed pressure on established property once buyer confidence returns.
5. Early Demand Signals Can Lead the Published Data by Six Months
Mortgage brokers and conveyancers are beginning to report more inquiries. These are early-stage signals because buyers often speak with a broker or lawyer before searching seriously or making an offer.
Niro estimates that the average buyer may take about three months to purchase, while quarterly market data can arrive another three months later. By the time broad statistics confirm stronger activity, informed buyers may have been competing for months.
The Verdict: The Warning Is Real, but the Headline Misses the Opportunity
NAB is not predicting a nationwide collapse. It is forecasting a moderate correction concentrated in Sydney and Melbourne, slower growth elsewhere, and stabilisation once interest-rate uncertainty eases.
For owners: low listings and low arrears mean there is little evidence of widespread forced selling. Track local stock, clearance rates and comparable sales rather than reacting to a national headline.
For buyers and investors: the opportunity is not everywhere. Focus on affordable markets where owner-occupier demand exceeds available supply, and use suburb-level evidence when choosing the right suburbs to invest in.
Summary
- NAB forecasts a roughly 7% capital-city fall from peak to trough
- The forecast is smaller than the 8.1% capital-city correction of 2022 to 2023
- Sydney and Melbourne face greater weakness, while growth may merely cool elsewhere
- New lending fell 5.4%, but listings remain below average and mortgage arrears are under 1%
- Price stabilisation could begin once the prospect of another rate rise fades
- Monthly dwelling approvals remain below the level needed to meet the housing target
- Broker and conveyancer inquiries may reveal returning demand months before official data
Frequently Asked Questions
NAB forecasts capital-city dwelling prices to fall about 7% from peak to trough. It expects Sydney and Melbourne to experience greater weakness, while growth in Adelaide, Perth and Brisbane may cool rather than turn negative.
Watch mortgage-broker inquiries, new listings, auction clearance rates, days on market and owner-occupier demand in individual suburbs. These leading indicators can improve months before quarterly price data confirms a recovery.
Dwelling approvals remain below the monthly level needed to meet the national housing target. High construction costs, builder failures and project delays make it difficult for new supply to keep pace with population growth.
NAB and other economists expect greater stability toward late 2026, with possible appreciation in early 2027. The timing depends heavily on interest-rate certainty and whether spring listings remain constrained.
The data points more strongly to buyer hesitation than forced selling. New listings are below their five-year average, Sydney listings are 14% below average, and mortgage arrears remain under 1%, close to their long-term norm.
