Where prices are
These are the official ABS medians for established houses in Greater Perth: actual sale prices, published quarterly. They lag the monthly private indices by a few months, but they are the public record the model is built on.
Expensive, or about to correct?
People blur two different questions together. We answer them separately.
On affordability — price versus what a typical household can borrow, compared with Perth's own 2002–2019 norm — Perth is 4th most stretched of the five capitals. Every capital is expensive on this measure; the question is who is most exposed.
On the second test — price versus what it costs to build a comparable home, adjusted for population growth — Perth has already cooled to around what it costs to build, so much of the air has come out.
What would hurt most
In our combined-downturn scenario (rates up, migration stalls, wages soften) Perth is 3rd most exposed of the five capitals. Unusually, Perth is more exposed to a migration slowdown than to a further rate rise — population growth is doing more of the work here than anywhere else.
The backdrop is the same for every city: the cash rate is on hold at 4.35%, the 10-year bond is near a 15-year high and core inflation is stuck around 3.6%, so the market has swung from expecting rate cuts to pricing higher-for-longer. Conditions are neutral / transitional on our macro read.
Why trust the read?
We calibrated the model on 2011–2019 data only, so it never saw the 2020s. It still flagged the 2021 boom as over-valued and the 2023 rate-shock correction as back to fair. It also named Adelaide and Brisbane as the most stretched capitals before the 2026 downturn reached them. How the model works →
