Western Australia's strong mining and resources sector means household incomes are among the highest nationally, which has kept mortgage stress relatively contained at 25.5%. However, Perth property prices have risen sharply since 2023 with limited new supply, and those outside the mining sector — retail, hospitality, education workers — are feeling rate rises more acutely. Regional WA towns like Karratha and Port Hedland have unique dynamics tied to mining cycles.
At the average WA mortgage of $480,000 on a 6.5% variable rate over 30 years, monthly repayments are approximately $3,034. Against the state median household income of $102,000, that represents roughly 35.7% of gross income — above the 30% stress threshold.
