Mortgage Stress Hits 421,725 Households: Is Your Postcode on the List?

Key takeaways

• 421,725 households across 80 postcodes were in mortgage stress in June 2026, up 18% year on year.
• The conventional threshold is housing costs above 30% of gross household income.
• Stress has appeared in higher-income postcodes, where large loans magnify each rate rise.
• Hardship assistance is available before you default, and applying early preserves more options.

What does the measure actually capture?

The 30% threshold is a screen, not a diagnosis. It compares housing costs to gross income without regard to what else a household must pay, which is why it both over- and under-states hardship depending on circumstances.

A household on $250,000 spending 35% on housing may be entirely comfortable. A household on $80,000 spending 28% may not be, once childcare, transport and energy are counted. A better personal test is what remains after every fixed cost, not the ratio itself.

Why is it spreading to higher-income postcodes?

Because the dollar impact of a rate rise scales with the size of the loan, not with income. The same 0.75 points that added $249 a month to a $500,000 loan added $498 to a $1,000,000 loan.

Households in higher-priced suburbs typically carry proportionally larger mortgages, so a given percentage-point move consumes a larger dollar share of their budget. Add the fixed-rate cliff — borrowers rolling off 2023 fixed loans onto 2026 variable rates — and the increase arrives as a single step rather than gradually.

What to do if you are in the numbers

1. Ask your lender to reprice. Free, fast, and existing customers frequently pay more than new ones.
2. Review the loan structure. Extending the remaining term reduces the repayment, at the cost of more total interest.
3. Apply for hardship early. Under the National Credit Code and the Banking Code of Practice a lender must genuinely consider a hardship request — and you do not need to be in arrears to make one.
4. Get free financial counselling. The National Debt Helpline (1800 007 007) is independent and free.

The single most common mistake is waiting. Options narrow sharply once arrears accumulate and a default is recorded.

Frequently asked questions

Is mortgage stress the same as being behind on repayments?

No. It measures the share of income going to housing, so a household can be classified as stressed while still meeting every repayment — often by cutting spending elsewhere or drawing on savings.

Does asking for hardship affect my credit file?

A hardship arrangement may be recorded as a financial hardship indicator for a limited period. That is considerably less damaging than missed payments or a default, which stay on file for years.

What if my lender refuses to help?

Use the lender's internal dispute resolution process, then escalate free of charge to the Australian Financial Complaints Authority. A lender generally cannot commence enforcement while a properly lodged AFCA complaint is open.
