Perth house prices rose 82 per cent in five years. Then the market turned, and the latest fall is the largest the city has ever recorded. Reports of a burst bubble are early, but the direction is clear.
This was the story of the national upswing. Perth started from a low base, looked cheap next to Sydney and Melbourne, and drew interstate buyers and investors chasing yield. A move that big, that fast, leaves a market exposed once borrowing costs bite.
Why a record fall follows a record run
Big rises and big falls often share the same cause. Perth’s climb was driven by affordability: lower entry prices, strong rental returns and a tight supply of homes for sale. Affordability stops working as a driver once prices catch up with incomes.
At that point the market leans on credit. Buyers borrow close to their limit, and a change in interest rates hits them first. We have covered how house prices, downturns and auctions interact, and Perth is following a familiar pattern: fewer buyers at auction, more withdrawn listings, and then price cuts.

How this compares with earlier WA cycles
Western Australia has been here before, though the trigger differed. Earlier busts followed the end of mining investment booms, when jobs and population growth slowed sharply. This time the economy is not in a comparable slump. The pressure is coming from the cost of money and from prices that ran ahead of wages.
That matters for the outlook. A downturn driven by lost jobs tends to be deeper and longer. One driven by rates can stall quickly if borrowing costs ease, but it can also run on if buyers stay stretched. The honest answer is that the data does not yet say which path Perth is on.
Testing how far a correction could run
Price-to-income ratios are the cleanest yardstick. After an 82 per cent rise, the ratio in Perth sits well above where it started the cycle. Prices do not have to fall back to the old ratio, because wages have risen and lending standards differ. But the gap between today’s ratio and the pre-boom level shows how much room there is to fall.
A rough rule of thumb: the further prices have run beyond income growth, the more a market relies on cheap credit to hold its level. Remove that support and the adjustment tends to come through price rather than volume.
The sellers who feel it first
Not every owner is exposed. Those who bought before the boom hold large equity buffers. The pressure lands on recent buyers who borrowed heavily near the peak. We looked at this in our piece on negative equity as another rate rise nears, and the same risk applies in Perth if falls deepen.
Investors are the other group to watch. Many were drawn by yields. If rents flatten while prices fall, the return that justified the purchase weakens.
What we still do not know
- How steep the monthly falls are, and whether they are widening or narrowing
- Whether the fall is broad or concentrated in the dearer suburbs
- How listings and clearance rates are moving behind the headline index
- Whether interstate buyers are retreating or simply pausing
Price indexes also lag sales. Our look at why price data is the last to know explains why the first reported falls often understate what is happening on the ground.
For buyers waiting on the sidelines
A record fall will tempt some buyers to wait for the bottom. That is a legitimate strategy, but it carries its own risk, which we unpack in Perth property prices: is waiting for the bottom really a gamble?. The practical step is to test your own repayments against a higher rate before deciding, rather than guessing the market low.
