Australia’s pool of households at risk of mortgage default has reached a record in the OurTop10 Default Loan Report. Digital Finance Analytics estimated that 24,546 households across 70 postcodes could default within the next 12 months, 24 per cent more than a year earlier.
The quarterly rise slowed to 3 per cent, but the direction of travel matters more than that single measure. According to realestate.com.au, pressure is extending beyond the growth corridors that absorbed the first phase of the squeeze.
Key facts:
- The estimated at-risk population is 24,546 households across 70 postcodes.
- That is 24 per cent higher than a year ago and the highest reading in the series.
- Victoria has the largest number of at-risk households across its 10 ranked postcodes.
- Queensland has the second-largest total, while South Australia recorded the fastest quarterly rise.
- The figures model future default risk over 12 months; they are not counts of loans already in arrears.
Where the pressure is concentrated
Victoria remains the largest hotspot in the dataset. Cranbourne, in Melbourne’s south-east, is the country’s biggest centre of concern, with 1364 households considered at risk after an 8 per cent quarterly increase.
South Australia recorded the fastest state and territory increase. Its ranked postcodes rose 13.6 per cent in the quarter to 1874 households. Encounter Bay had the largest quarterly jump nationwide, climbing 78 per cent from 93 to 166 at-risk households.
Queensland’s statewide total appeared nearly unchanged, rising 0.6 per cent to 5139 households across 10 ranked postcodes. The underlying movement was less comfortable. Manunda in Cairns increased 25 per cent from 359 to 448 households, while Craignish on the Fraser Coast rose 17 per cent to 499. Yatala on the Gold Coast reached 560 after an 11 per cent quarterly increase.
Toowoomba had Queensland’s biggest total at 616 households, although its figure fell 5 per cent for the quarter. New South Wales recorded 3782 at-risk households across its ranked postcodes, down 1.2 per cent, but Blacktown rose 27 per cent during the quarter and 76 per cent year over year.
These mixed readings show why a single statewide number can be misleading. The signal is uneven.
Why the slowdown offers little comfort
OurTop10 research head Mansour Soltani said a slower quarter did not mean conditions were better. At the same time, reported hardship requests are increasing, according to his assessment. Many households have used up the savings buffers that helped them withstand earlier rate rises.
The report’s figures are modelled estimates rather than recorded defaults. That distinction matters for real estate news because the metric represents households expected to face default within 12 months. It offers a forward-looking warning, not a count of completed foreclosures.
Higher interest rates and living costs continue to squeeze household cash flow. The report also did not yet fully reflect September’s rate increase, nor any possible later move. The current reading may therefore understate the pressure still working through household budgets.
Soltani compared Cairns and the Fraser Coast with earlier episodes in Melbourne and Perth’s outer suburbs. His sequence is grim but familiar: cash-flow stress appears first, savings are drawn down, and defaults follow later. If that pattern holds, weak readings now may precede larger losses later.
Our analysis
For property investors, the relevant change is geographic. Mortgage stress is no longer confined to the areas that experienced the sharpest early pressure. It is appearing in places once treated as more resilient, including regional Queensland and parts of South Australia.
That shifts the lens for investors and analysts. Market-wide indicators can obscure local deterioration, while a national headline can imply either broad uniformity or insignificant variation. Neither is useful. The relevant question is whether arrears and hardship pressures are appearing in postcodes where borrower buffers, employment conditions and housing liquidity differ from the earlier hotspots.
The figures also distinguish affordability stress from property-price weakness. A household can become distressed without its home immediately losing value. Stress may first reduce transaction volumes, force longer negotiations or leave owners unable to refinance on acceptable terms. Investment-property owners should examine tenant arrears and rent affordability rather than assume every stressed postcode will produce an immediate price decline.
Commercial real estate is not directly measured here, but housing credit conditions can still matter. Persistently stressed borrowers may hold property longer, accept lower yields or delay upgrades. Banks dealing with more problem loans may also become more cautious on lending. Those effects would arrive through capital availability and investor sentiment rather than the report’s household counts.
The quarterly slowdown should therefore be read cautiously. A 3 per cent increase in a much larger pool can still mean materially more households entering the risk group. The question is whether subsequent data confirms that stress is broadening or begins to stabilize.
A practical investor check
Say you are assessing a residential rental portfolio concentrated in a regional Queensland postcode. The statewide risk figure is almost flat, but one nearby suburb has jumped 25 per cent in a quarter. Should that change your decision?
Not automatically. It should change the questions you ask. Review arrears and hardship requests, inspect the tenant mix and test rent-to-income sensitivity. Identify whether units are held by owner-occupiers or investors, since their responses to financial pressure may differ.
For direct property ownership, include a stress case in the model. Assume slower leasing, more renewal concessions or a tenant requiring a payment plan. For a fund or REIT, assess how concentrated exposure affects portfolio liquidity and refinancing. The report does not prove that prices will fall in Manunda or Encounter Bay. It does show where households may struggle to meet mortgage commitments.
What to watch next
Watch hardship requests, arrears, refinancing activity and actual defaults in the postcodes driving the increase. Those measures will show whether the modelled risk is becoming realized stress.
The next report should reveal whether the 24 per cent annual increase is stabilizing. Victoria still carries the largest total, but the sharper recent movements in Manunda, Blacktown and Encounter Bay suggest that the map of stress is changing.
For Australian property investors, there is no basis for treating the slowdown as an all-clear. Assume mortgage stress is broadening, examine exposure postcode by postcode and stress-test income, leasing and refinancing assumptions before relying on stable aggregate figures.
Key takeaways
- The estimated pool of households at risk within 12 months has reached 24,546, a series high.
- Recent pressure is broadening into regional Queensland and South Australia despite a slower quarterly increase nationally.
- Modelled default risk is not the same as loans already in arrears.
- Investors should stress-test local exposure using hardship, arrears, leasing and refinancing data.
