House prices fell in all but two of the nation's capital cities over the three months to the end of June amid confirmation consumer confidence has yet to be buoyed by tax cuts or falls in official interest rates.

The Australian Bureau of Statistics (ABS) on Tuesday reported residential property prices fell 0.7 per cent nationally in the June quarter to be 7.4 per cent down over the past 12 months. Prices in Melbourne and Sydney dropped 0.8 per cent and 0.5 per cent respectively for the quarter, to be 9.3 per cent and 9.6 per cent lower since June 2018.

ABS chief economist Bruck Hockman said there were different factors at play in the nation's two largest property markets. "The falls in Melbourne were driven by detached dwellings, while attached dwellings drove the fall in Sydney," he said.

Only one capital, Hobart, reported higher prices over the past 12 months, with prices up 2 per cent. The biggest quarterly drop was in Darwin, where prices fell 1.8 per cent to be 5 per cent lower over the past year. Prices fell 0.7 per cent in Brisbane (to be 2.7 per cent lower over the year), 0.6 per cent in Adelaide and 1.4 per cent in Perth.
