Australia’s mortgage burden exceeds 1989 levels despite lower interest rates
Consensus Summary
Australian households are currently facing a heavier mortgage burden than during the late 1980s, when interest rates peaked at 17.5%, according to KPMG economist Terry Rawnsley. While current home loan rates average 8.3%, households now dedicate 5.4% of their income to servicing mortgages and consumer debt, compared to 5.7% in early 1990. Rawnsley’s analysis shows that despite lower nominal rates, rising home values and increased borrowing have made mortgage stress worse in recent years. The global financial crisis saw the highest interest burden on Gen X households, with repayments peaking at 7.9% of income in 2008. Victoria’s households now face the highest interest repayment burden at 6.9%, driven by increased homeownership among first-time buyers. Economists disagree on future interest rate movements, with the RBA balancing inflation control against economic slowdown and rising unemployment. Both sources agree that housing affordability remains at record lows, with recent price declines offering only temporary relief.

Points of Difference
Details reported by only one source:
- Terry Rawnsley described his research as a 'myth-busting' exercise to rebut claims that previous generations faced harder mortgage conditions.
- Climbing interest rates, rising cost of living due to the Middle East conflict, and recent tax reforms triggered a dip in Sydney and Melbourne home prices over recent months.
- Tim Reardon, chief economist at the Housing Industry Association, said housing affordability is at its worst on record since 1994.
- Reardon criticized Labor’s reforms to capital gains tax (CGT) and negative gearing, stating they would reduce much-needed housing supply.
- Reardon suggested that keeping rental vacancies above 3% would stabilize home prices, calling it a success in housing policy.
- Gen X households faced the heaviest interest rate burden during the global financial crisis, with total interest payments peaking at 7.9% of household income in June 2008.
- Between September 2005 and March 2013, interest repayments averaged 6.6% of household income, with central banks losing control of rates during the GFC.
- Victoria’s higher debt burden is due to more affordable homes lifting homeownership rates, increasing average interest repayments.
- Victoria saw the largest increase (3.8 percentage points) in interest repayments as a share of household income from 2021-22 to 2024-25.
- The RBA has signaled willingness to control inflation but is conscious of a weakening economy and rising unemployment.
Contradictions

- The Guardian states that home prices in Sydney and Melbourne have dipped over recent months, while the ABC notes that national home values are still 7.3% higher than a year ago despite a 1% fall in June 2026.
- The Guardian mentions that the total debt burden figure will push towards 6% once the full impact of 2026’s three interest rate hikes flows through, while the ABC states that another rate rise would push repayments towards 6% of household income without specifying the exact current figure.
