Six of the suburbs with the biggest average annual growth are huddled just over the West Gate Bridge.
Braybrook topped the list, with house prices rising an average of 8 per cent a year to a median of $462,500.
RP Data figures show it beat top-end suburb Armadale, which was second place with 7.8 per cent.
Ripponlea was the best performer for units, with average annual growth of 9 per cent.
And Junortoun, east of Bendigo, was the country winner.
Prices in the little town rose an average of almost 10 per cent every year from 2001 to 2011.
Barry Plant Sunshine director Jason Allen is not surprised the western suburbs performed so strongly.
"It's always been affordable, which allows first-home buyers to get into the market and, in the past year, a lot of investors have jumped in," he said.
"They are still affordable, they are big blocks, there are period houses that you can renovate."
