House values fall – but homes are not getting more affordable

Home values across the nation’s capital cities have suffered their biggest fall in almost four years, led by sharp drops in Sydney and Melbourne as interest rate settings, expensive dwellings and the federal government’s property tax changes combine to slow the market.

As new figures show the nation’s housing market has never been less affordable, data compiled by Cotality, released on Wednesday, showed national dwelling values dipped by 0.4 per cent in June. It was the largest single monthly fall since December 2022.

Sydney house values alone tumbled by 1.5 per cent in the month to be 4.2 per cent lower since the start of the year. In Melbourne, house values fell another 1.3 per cent with values 1.2 per cent down over the past 12 months.

Some cities continue to grow, with house values in Perth lifting another 0.7 per cent to be 23.6 per cent up over the past year, while in Brisbane they lifted by 0.2 per cent to be 16.8 per cent higher than this time in 2025.

The government has come under attack from the Coalition over the strength of the property market, with claims the budget’s changes to negative gearing and capital gains tax have left some people in so-called “negative equity” – where a person owes more on a property than it is worth.

Cotality research director Tim Lawless said three factors were weighing on the property market, including the government’s tax changes and the Reserve Bank’s three interest rate hikes between February and May.

“Even before interest rates rose by 75 basis points, we were seeing affordability hurdles weighing on buyer demand,” he said.

“Higher cost-of-living pressures, deeply pessimistic sentiment and a further dampening of demand via property taxation changes announced in the federal budget are all contributing to weaker housing conditions.”

Over the past three months, total dwelling values in Sydney (minus 3.2 per cent), Melbourne (minus 2.6 per cent) and Canberra (minus 1.3 per cent) have all gone backwards. But they have lifted in every other capital city market, led by Darwin’s 5 per cent and Perth’s 2 per cent.

Year-on-year, Melbourne dwelling values have fallen by 0.9 per cent. They have climbed everywhere else, although both Sydney (0.3 per cent) and Canberra (2.9 per cent) have experienced increases well short of the inflation rate.

Despite the drop in values, the median house value in five capitals – Sydney ($1.6 million), Brisbane ($1.2 million), Adelaide ($1.01 million), Perth ($1.1 million) and Canberra ($1.04 million) – remains above the $1 million mark.
