Perth property listings have hit a three-year high, with 6,121 properties on the market as of June. This marks a significant shift from the frenzied buying activity earlier in the year. According to new data from the Real Estate Institute of Western Australia, the number of properties available for sale has increased by 14.8 per cent in the past month.

And it's not just the number of listings that's increased - the time it's taking to sell properties has also gone up. As of June, houses were spending 18 days on the market, which is four days slower than May and five days slower than a year ago. Units were selling in a median of 18 days, five days slower than May and five days slower than in June 2025.

So what's behind the increase in properties on the market? Suzanne Brown, president of the Real Estate Institute of Western Australia, believes it's due to investors selling their properties in response to the federal budget. 'We're probably seeing investors, in particular, potentially selling some of their investments due to the budget,' she said.

'We have also seen a noticeable change to demand in the wake of the Federal Budget and the back and forth over the taxation legislation. Despite there being more properties on the market, sales activity decreased in June, more so than you would expect at this time of year,' Brown said.

Brown also pointed out that the increase in listings is partly due to homeowners being more willing to sell their properties as there are more options available for them to buy a new home. 'I always said before when there were less listings, it was a catch-22. There were a lot of people wanting to sell, but ... they weren't selling until they found a new property,' she said.

The suburbs that have seen the greatest percentage increase in new listings from the March to June quarter are Warwick (up 140 per cent), Gwelup (up 128.6 per cent), Huntingdale (up 126.3 per cent), Kallaroo (up 125 per cent), and Darlington (up 122.2 per cent). The suburbs that have seen the greatest percentage increase in the number of new unit listings are Crawley (up 133.3 per cent), Westminster (up 122.2 per cent), Osborne Park (up 113.3 per cent), Morley (up 100 per cent) and Northbridge (up 70 per cent).

Leading the way for the suburbs with the most active property listings as of June 30 are Baldivis, Perth and East Perth. Brown believes that the increase in listings is a sign of a more balanced market, where buyers have more choice and are no longer racing to secure a property.
