$450 a month was wiped from discretionary spending for Australian families with a mortgage and two cars in the March quarter, the sharpest quarterly fall in household spending power since 2004.
Two Reserve Bank rate hikes and petrol prices above A$2.50 a litre after late-February attacks on Iran drove the squeeze, erasing almost all budget gains households made in 2024 and 2025.
The hit was uneven: renter couples lost A$180 a month, outright homeowners A$140, while the lowest 20% of earners faced essential costs exceeding income by about A$81 a week.
A$782 was stripped from the average household's non-essential spending over the year to March 2026, and Polis Partners said a May rate rise and renewed Middle East conflict could deepen the pressure.
