South Australia offers more affordable property than the eastern seaboard, but lower median incomes mean the rate hikes hit proportionally harder. Adelaide has seen steady price growth, and the city's northern and southern suburbs have higher concentrations of mortgage stress. The recent state election brought a Labor landslide, with cost of living cited as a dominant issue for voters.
At the average SA mortgage of $445,000 on a 6.5% variable rate over 30 years, monthly repayments are approximately $2,813. Against the state median household income of $79,000, that represents roughly 42.7% of gross income — above the 30% stress threshold.
