Median home values in Perth fell by 1 per cent in August, while there was little movement across other capital cities, new research shows.
Hobart mirrored Perth with a one per cent fall, while there was little price movement in Sydney, Melbourne and Brisbane, the RP Data-Rismark August Index showed.
Adelaide and Canberra prices increased more than one per cent, while Darwin home values fell half a per cent.
The index posted a 1.6 per cent increase in Australian home values over the past three months but a fall of 2.4 per cent over the year to August.
During the quarter to August, Darwin was the best performing capital city, registering 5.2 per cent growth.
This was followed by Melbourne at 2.5 per cent, and Sydney at 2.4 per cent.
Perth and Brisbane recorded marginal growth of 0.2 per cent and 0.6 per cent respectively over the three-month period.
RP Data research director Tim Lawless said Sydney dwelling values increased in five of the past eight months, helping to provide a cumulative capital gain of 1.9 per cent over the year to date.
"Sydney is proving to be one of the most consistent performing capitals this year," he said.
A rebound in Melbourne was also encouraging, given more worrying signals earlier in the year.
"Improved affordability since June has helped dwelling values rise across every capital city over the three months ending August 2012, apart from Adelaide," Mr Lawless said.
"The big question is, can this growth be sustained?"
Mr Lawless said the spring selling season would be a good litmus test.
The highest rental yields for houses in the quarter were in Darwin at 5.8 per cent and the lowest yield were in Melbourne at 3.6 per cent.
