Mortgage stress hit 450,000 households this week — the postcodes behind it aren’t ours
Two reports landed within days of each other pointing the same way: more households are falling behind on their mortgage than at any point since either index began tracking it. The number doing the rounds, 450,000, is worth unpacking before it gets repeated as a national total, because it isn’t one — and where the stress is concentrated tells a more useful story than the headline does.
OurTop10 Mortgage Stress Report (Digital Finance Analytics) · September 2026 quarter
| Households in stress, 77 tracked postcodes | 450,539 |
| Quarterly increase | +31,318 (7.5%) |
| Consecutive quarterly rises | 3rd straight |
| Annual increase, those postcodes | 21% |
| Postcodes (of 77) that rose this quarter | 61 |
A specific set of postcodes, not a national total
The 450,539 figure is a count across the 77 postcodes the OurTop10 report tracks nationally — the areas with the highest exposure to mortgage stress, not every household in Australia. It’s a genuine and continuing rise, the third straight quarterly increase since the index began, but it’s a different thing to a national figure. Separately, Roy Morgan’s broader measure puts 32.3% of all mortgage holders nationally “at risk” of stress in the three months to August, up 8.4 percentage points since January and just below an 18-year high.
Where it’s actually concentrated
Victoria’s tracked postcodes added more stressed households than any other state — 104,325, up 11.2% — and some of the sharpest individual rises are in wealthier, heavily-leveraged suburbs rather than the usual outer-suburban story. Sydney’s Drummoyne went from 224 to 1,591 severely stressed households in three months. Nationally, the groups most exposed are recent first home buyers who bought with small deposits, including users of the government’s 5% deposit scheme, and families in outer-suburban growth estates.
The postcodes driving the headline number aren’t the ones we work in — but a tighter household budget nationally still feeds into what every buyer can borrow and offer.
The two Queensland names in the report
Queensland gets two specific mentions. Manunda, in Cairns, recorded the single largest postcode rise in the country — up 156% in three months — and Toowoomba is flagged as a regional hotspot. Neither Thornlands, Victoria Point nor any other Redlands postcode appears anywhere in either report.
The Redlands read
Selling, buying or holding
If you’re selling, the households showing up in this data aren’t the ones making offers in our market. A clean, well-priced home here should still move on its own merits.
If you’re buying, a tighter household budget nationally still shapes bank serviceability settings and borrowing capacity everywhere, even where your own postcode isn’t named.
If you’re holding, a report naming Victoria, Sydney, Cairns and Toowoomba isn’t a signal about your own street. It’s useful mainly for knowing where the broader risk actually sits.
