Australia’s housing boom is grinding to a sudden halt, as a massive wave of property listings floods the market, distressed sales spike, and asking prices begin to fall across five of the nation’s major capital cities.
Data released by property analytics firm SQM Research reveals that total national residential listings spiked by 10.4% in May to 258,803 dwellings.
Crucially, overall available housing stock is now 0.8% higher than it was this time last year, marking the first annual increase in housing supply in over a year and signalling a dramatic shift in market power toward buyers.
The figures point to a market abruptly losing steam under the weight of persistent inflation and high interest rates.
“May’s data points to a market that is losing momentum,” said Louis Christopher, Managing Director of SQM Research.
“National listings recorded their strongest monthly rise in some time and have moved back into positive annual territory for the first time in over a year. When supply returns this quickly while prices stall, it is usually an early sign that the market is at turning point, keeping in mind April recorded a seasonally low level of listings.”
Prices fall in key capitals
While the aggregate national combined asking price appeared flat with a minor 0.1% monthly tick upward, the headline figure masks a deepening pullback across Australia’s primary wealth centers.
Five of the eight capital cities – Sydney, Melbourne, Brisbane, Perth, and Adelaide – recorded monthly declines in combined asking prices as buyers balked at stretched valuations.
Sydney property values eased by 0.3% over the month, though they remain 5.6% higher year-on-year. Melbourne fell further, recording a 1.1% monthly drop to sit just 4.4% higher than May 2025. Adelaide recorded the sharpest monthly correction with a 1.7% slide in combined asking prices.
Even the previously unstoppable resources-driven markets showed signs of exhaustion, with combined asking prices dipping 1.0% in Brisbane and 0.8% in Perth.
“The flat national price reading masks what is actually happening across the major capitals,” Mr. Christopher said.
“Sydney, Melbourne, Brisbane, Perth and Adelaide all recorded monthly falls in combined asking prices. The only markets still rising are the three smallest – Canberra, Darwin and Hobart. With five of the eight capitals now declining month-on-month, the moderation we flagged earlier this year is broadening.”
Mortgage stress begins to surface
Compounding the supply influx is a worrying 5.1% monthly jump in distressed property listings nationwide to 3,847 homes.
The spike was led by a near 9% surge in forced sales across Western Australia (+9.1%), South Australia (+9.0%), and Queensland (+8.9%). In the ACT, while the monthly increase was 6.8%, distressed stock has skyrocketed by 38.2% compared to May last year.
Analysts warn that while national distressed listings are still lower than last year’s levels on a year-on-year basis (-16.2%), the annual data is a lagging indicator that is concealing a sharp, real-time shift in economic pain.
“Distressed listings jumped 5.1% over the month, led by Western Australia, South Australia and Queensland, all up around 9%,” Mr. Christopher warned.
“The annual figure is still negative, but year-on-year comparisons lag – the monthly trend is what matters here, and it is rising. The ACT is already 38% above where it was a year ago. We are watching this closely as an early indicator of mortgage stress.”
A tsunami of supply
The sudden build-up of properties comes from two fronts: a 5.0% national lift in brand-new listings entering the market, and a heavy 10.5% accumulation of older stock (properties on the market for longer than 180 days) as buyers sit on their hands.
Brisbane led the total supply influx with an 18.5% month-on-month surge in listings, followed closely by Perth at 16.0% and Sydney at 14.8%. For Perth, which has suffered from chronic under-supply, May marked the third consecutive month of substantial listing growth, offering long-awaited relief to desperate buyers.
With the Reserve Bank of Australia expected to keep interest rates higher for longer to combat sticky inflation, property experts warn that the balance of risks has firmly tilted against homeowners.
“This is consistent with the more cautious view we have held since March,” Mr. Christopher said.
“With inflation sticky and rate relief pushed further out, the larger capitals – Sydney and Melbourne in particular – remain the most exposed. The balance of risk has clearly shifted to the downside, and the next few months will confirm whether May was the inflection point.”
