Australian house prices fall in every capital city for first time in 15 years

Domain's September Quarter 2026 report shows house prices declined in all Australian capital cities, the first such synchronized fall in 15 years and only the second on record. Sydney led the decline with a 4.7% quarterly drop to A$1.66m, a two-year low. The breadth of the decline signals a broad-based housing downturn, likely reflecting higher interest rates and affordability constraints, with implications for household wealth and consumption.
