The Reserve Bank of Australia raised the cash rate to a 15-year high of 4.6 per cent, triggering widespread market adjustments that have pushed national home prices down by 5.2 per cent from their March peak, according to data from Cotality.
RBA Rate Hike Drives Property Prices Down Across Capital Cities
Following the central bank’s decision—its fourth rate increase of the year—property values contracted across almost every capital city in September. Cotality data shows Brisbane recorded a 1.5 per cent drop in home values during September alone, bringing the median price down to $1.05m after a $59,000 decline since May. Sydney median values dropped 1.4 per cent in the month, sitting 8.6 per cent below their record March high, which equates to a $112,000 reduction. Melbourne property prices fell 0.7 per cent in September, marking a $53,000 decrease for the median home since March. Darwin stood as the sole exception, posting a 0.4 per cent rise in September.
Construction Sector Grapples With Surging Costs and Debt Pressure
Higher interest rates have increased the cost of financing debt-funded construction projects, reducing project feasibility and slowing the pipeline of new housing. Equifax Australia general manager commercial Brad Walters said that a 4.6 per cent cash rate erodes household financial buffers and magnifies the impact of construction delays. iCIRT Construction Index data indicates that 35 per cent of Australians managing a build or renovation cannot absorb a project cost increase of 1 to 5 per cent, while only 23 per cent of new builds or renovations finish on schedule. Equifax data shows small construction business exits surged 58 per cent in the second quarter of 2026 against a 19 per cent drop in new entrants, as subcontractor capacity stalls under rising material and labour costs.
Housing Industry Warns of Deepening Supply Crisis
According to the ABC, Western Sydney home owner Chris Shaw noted that half of his household income goes toward mortgage repayments following the rate increases. Conversely, some recent buyers like 26-year-old Parramatta owner Jonathon Noujaim expressed optimism that falling prices would help other young people enter the market. Meanwhile, the federal government reported on Thursday that over 102,000 people have been supported by the expanded 5 per cent deposit scheme in the year since its expansion, helping maintain entry-level demand despite broader market headwinds.
