Australian residential property prices are showing signs of cooling as high interest rates and increased supply weigh on market momentum. According to the CoreLogic Home Value Index, while national values recorded a 20th consecutive month of growth in September 2024, the pace of that increase has decelerated significantly compared to earlier in the year.
Why is the Australian housing market slowing down?
The primary driver behind the current market shift is the restrictive monetary policy maintained by the Reserve Bank of Australia (RBA). Since May 2022, the RBA has kept the cash rate at elevated levels to combat inflation, which directly impacts mortgage serviceability for both new and existing borrowers.
According to Reserve Bank of Australia board minutes, the central bank maintains a “restrictive” stance, noting that inflation remains above the target range. This high-interest-rate environment limits the borrowing capacity of potential buyers, effectively placing a ceiling on how much they can bid at auction. Furthermore, the persistence of these rates has led to a cooling in buyer sentiment, as households prioritize debt management over property acquisition.
How does increased supply affect price growth?
Increased listings have provided buyers with more leverage, shifting the market dynamics in several capital cities. Data from CoreLogic indicates that total advertised supply has trended upward in regions like Sydney and Melbourne.
When inventory levels rise, the “fear of missing out” (FOMO) that characterized the post-pandemic market begins to dissipate. Sellers are finding that properties are staying on the market for longer periods, and clearance rates—a key indicator of buyer demand—have moderated. This balance between supply and demand suggests that the rapid price surges observed in 2023 are unlikely to be repeated in the near term.
What is the outlook for house prices?

Market analysts and financial institutions remain divided on whether the market will experience a sustained correction or a period of stagnation. The Australian Financial Review has reported that major banks are revising their growth forecasts downward, citing stretched affordability as a primary barrier to entry for first-home buyers.
While national prices have not yet entered a broad-based decline, the divergence between cities is widening. Perth and Brisbane have continued to record stronger growth due to lower relative starting prices and tight rental markets, whereas the more expensive markets of Sydney and Melbourne are showing more pronounced fatigue.
Key Factors Influencing Market Direction
* Interest Rates: The RBA’s cash rate trajectory remains the most critical variable; any hint of a rate cut could reignite demand.
* Affordability Constraints: High debt-to-income ratios are preventing many buyers from entering the market at current valuations.
* Rental Market Pressure: A low national vacancy rate continues to provide a floor for property values, as investors remain active despite higher borrowing costs.
* Regulatory Changes: Potential shifts in negative gearing or capital gains tax policies, though currently speculative, remain a point of discussion for long-term market stability.
For homeowners and investors, the current environment suggests a transition from a seller’s market to a more neutral territory. Future price movements will largely depend on when the RBA signals a pivot toward easing monetary policy, which would alleviate the current pressure on household budgets.
