Australian property prices have now fallen for six months in a row, and the cash rate that is driving the slide has not stopped moving. The Reserve Bank has lifted rates four times in 2026, in 25 basis point steps in February, March, May and September. The increase lifted the cash rate to 4.60 per cent, up from 3.60 per cent and the highest level since 2011.
The obvious question is whether a fifth hike is coming. The more useful question is what happens to prices even if it does not.
Property prices and interest rates: the lag is the story
Rate rises do not hit prices on the day they are announced. They work through a chain. The cash rate lifts lender variable rates. Higher repayments eat into household budgets. Lenders then assess borrowers against the higher rate, which shrinks how much people can borrow. Smaller borrowing capacity means lower bids, and eventually lower sales prices.
That chain takes months, and in some parts of it, years. Fixed-rate borrowers only feel the change when their term rolls off. Buyers who were pre-approved before the hikes still carry old assessments. So the full effect of 100 basis points of tightening is not yet in the numbers.
National dwelling values fell 1.1 per cent in September alone and now sit 5.2 per cent below the March 2026 high. That is a meaningful drop, but it reflects only part of the pipeline.
Key numbers
- Cash rate: 4.60 per cent, up from 3.60 per cent in 2026
- National values: down 5.2 per cent from the March peak
- September monthly fall: 1.1 per cent nationally
- RBA modelling: a sustained 200 basis point rise could eventually lower prices by about 30 per cent
Where the damage started, and where it has spread
Prices first fell in the pricier markets, and the decline then spread more widely. September’s monthly falls were broad:
- Brisbane: 1.5 per cent
- Sydney: 1.4 per cent
- Adelaide: 1.3 per cent
- Perth: 1.2 per cent
- Melbourne: 0.7 per cent
Darwin was the exception and bucked the trend.
The pattern makes sense. Higher-priced homes need bigger loans, so they are more sensitive to a drop in borrowing capacity. Upper-quartile houses in Sydney and Melbourne are already more than 10 per cent below their peaks. Cheaper stock and units look more resilient so far, because buyers priced out of larger loans tend to shift down the market rather than leave it.
Which borrowers carry the most downside
Not everyone is equally exposed. The people with the most unrealised downside are likely to be:
- Recent buyers at or near the peak. They bought at the highest prices with the smallest equity cushion, and they face the largest gap if values keep sliding.
- Borrowers coming off low fixed rates. Their repayment shock has not arrived yet. When it does, some will be forced to sell or refinance into a tougher assessment.
- Owners of higher-priced houses in Sydney and Melbourne. This is where the biggest falls have already landed.
Borrowers with long-held, low-debt properties have a buffer. A 10 per cent fall is uncomfortable for them, but it rarely forces any decision.
How far could this go?
The Reserve Bank’s own modelling suggests a sustained 200 basis point rise could eventually leave prices about 30 per cent lower. That is a long-run estimate, and the adjustment is slow. Population growth and housing supply can bend the path in either direction, so treat it as a scale of sensitivity rather than a forecast.
The next possible steps are a cash rate of 4.85 per cent, or 5.10 per cent if the Bank opts for a larger move. Either would likely reduce buyer demand and sales volumes further. Economists are split on whether another hike arrives before year’s end.
Here’s the catch: even if the Bank holds from here, the existing 100 basis points still has to flow through. A pause does not mean prices stabilise straight away.
What history says about timing
Rate cycles do turn. The late 1980s peak came near 18 per cent in 1989, with cuts starting in early 1990. The 2022-23 tightening cycle is a more recent reminder. Neither tells you when the bottom is, but both show that the pressure eventually eases once the economy absorbs the squeeze.
For buyers, a falling market with fewer competing bidders can create negotiating room. For sellers who do not have to sell, waiting may beat selling into weakness. For anyone refinancing, it is worth checking your repayment against our guide to RBA interest rates and repayments, and reading how some suburbs held up in why 70% of suburbs are still rising as rate fears build.
The practical take
Do not anchor on the RBA’s next decision. Stress-test your own budget at 5.10 per cent today, check how much equity you hold against the 5.2 per cent fall already recorded, and decide whether you could hold through a further 10 per cent drop without being forced to sell.
