Families are staring down a debt nightmare, with a record number of homeowners now at risk of defaulting on their loans after falling behind on their repayments, new industry data has revealed.
The figures showed the number of households at risk of default jumped 18 per cent nationally over the past three months, marking the steepest rise since risk tracking records began in 2001.
It’s raised fresh alarm over the pressure facing borrowers after three interest rate hikes this year, plus previous years of soaring living costs and stubborn inflation.
The research by Digital Finance Analytics, done for comparison group OurTop10, indicated households were running out of a buffer of emergency funds, leaving them vulnerable to more rate hikes.

Digital Finance Analytics director Martin North said this pressure was most acute for those who bought homes in recent years. Recent buyers had often stretched themselves too far to pay lofty house prices, he said.
Many of these buyers had spent years burning through savings after purchasing their homes and had reached a “tipping point”, Mr North explained.
“This is more about time in cash flow stress than anything else,” he said.
“More households are net monthly underwater … Banks have been actively intervening – through hardship schemes, interest only and refinance schemes – to avoid registering a default.
“However, despite this, some segments, including those with bigger loans, and those funded by small business, are emerging problems.
“We are seeing more hotspots now, and this looks more serious because there is no short-term exit from the current adverse economic settings.”
The OurTop10 reporting pointed to a differing reality for mortgage holders across states:
VICTORIA
Victoria’s most stretched postcodes with highest default risk
Three rate hikes since the start of 2026 have added more than 74,000 Victorian households to the hundreds of thousands already struggling with mortgage stress.
DFA mortgage surveys showed 611,311 homeowners across the state were battling to keep their residence as of July, following Reserve Bank hikes in February, March and May, compared to 536,984 in January.

Victoria’s top 10 postcodes at risk of mortgage default were dominated by Melbourne’s outer suburbs.
These areas lead Australia’s list of hotspots where people were in danger of losing their homes.
Mr North said a significant chunk of Melbourne homeowners susceptible to defaulting on their mortgages would have bought when the market peaked in 2021.
But they’ve since experienced no or little capital growth, especially in high population growth corridors, which would mean a forced sale could be catastrophic.
QUEENSLAND
Queensland’s new mortgage default hotspots
Thousands of Queensland families have been plunged into severe mortgage stress, sparking warnings of an impending wave of loan defaults and forced sales.
More than 9,500 households sank into negative cash flow in just three months — the second-highest net jump in the country behind Western Australia.
Years of soaring housing entry costs have dialled up the risk for mortgage holders in Brisbane.
The surge brings Queensland’s total number of stressed households across its top-ranked postcodes to 74,649.
Financial stress levels in the Sunshine State were third nationally behind Victoria and NSW for total volume of distressed borrowers. The outer suburbs of Brisbane bore the brunt of the squeeze.
Mr North warned today’s cashflow pressure lit the fuse for tomorrow’s loan failures, with recent buyers facing the heaviest strain.
“In Brisbane in particular, we saw a massive price rise, so debt-to-income is high and two incomes are now the norm,” Mr North said.
“Recent first-time buyers and people who traded up recently are under the most pressure.”
NEW SOUTH WALES
NSW postcodes with highest default risk revealed
NSW saw a 25 per cent jump in mortgage default risk in the three month period.
The Default Loan Report by OurTop10 estimated almost 4,000 NSW households were close to defaulting in just the 10 most stretched postcodes alone.
OurTop10 director Mansour Soltani said: “stress tells you who is struggling this quarter. Default risk tells you who may not make it through the cycle”.

Sydney’s most stretched areas tended to be outer suburbs. “Defaults are higher in high-growth corridors where households have bought with larger mortgages,” Mr North said.
“In high growth corridors, leverage is extended, and 40 to 45 per cent of incomes go on mortgage repayments in some areas.”
SOUTH AUSTRALIA
SA’s emerging default risk hotspots exposed
Cost of living pressures are biting South Aussies harder than ever, with the data revealing the risk of residents in one particular suburb defaulting on their mortgages had increased by 39 per cent this quarter.
Morphett Vale had the greatest number of households on the cusp of losing their home, with experts warning default risk was rising in many other areas.
