Highlights

  • Preliminary capital-city auction clearance fell to 48.2% across 1,223 auctions in early October 2026.
  • The result followed the Reserve Bank’s 29 September increase in the cash rate to 4.60%.
  • Unsold housing stock remained elevated, giving buyers more choice and extending selling periods.
  • Property tax changes scheduled from 1 July 2027 may further influence investor participation in established housing.
  • Future auction outcomes will help show whether the latest weakness is temporary or part of a broader slowdown.

Australia’s housing market entered October 2026 with softer auction conditions as higher borrowing costs and a larger pool of unsold properties weighed on buyer activity. The preliminary combined-capital clearance rate dropped below 50% on the first auction weekend after the latest cash-rate increase, placing renewed focus on borrowing capacity, housing Supply and the tax settings that will apply to Investment property from July 2027.

Auction Activity Softens After the September Rate Increase

Across the combined Capital cities, the preliminary clearance rate was 48.2% from 1,223 auctions. Auction volumes were 12.8% lower than the previous week. Sydney recorded 304 auctions, while Melbourne hosted 670, highlighting different activity levels across the two largest markets. Preliminary results can change as additional outcomes are reported, so final clearance figures remain important for assessing the depth of the slowdown.

The Reserve Bank raised the cash rate from 4.35% to 4.60% on 29 September 2026. Higher rates reduce borrowing capacity and increase repayment costs for buyers using debt, which can affect bidding behaviour and the number of properties that sell under the hammer.

Unsold Stock Gives Buyers More Choice

About 276,000 homes were reported as unsold in early October, with a growing share of properties remaining on the market for longer periods. A larger stock of available homes can reduce urgency among buyers and place more pressure on sellers to adjust timing or price expectations.

Distressed sales were also reported to have increased in September. While this does not by itself indicate broad financial stress, it adds another measure to watch as higher interest rates flow through Mortgage repayments and refinancing decisions.

Property Tax Changes Add Another Variable

From 1 July 2027, rental losses on established residential properties acquired after 7:30pm AEST on 12 May 2026 are set to be quarantined. Those losses will be available against residential property income and gains rather than salary or other income. Properties held before the Budget announcement are grandfathered, while qualifying new builds retain access to negative gearing.

The same reform package also changes the Capital Gains Tax treatment applying from 1 July 2027. These rules may alter after-tax Cash Flow calculations for some investors considering established dwellings, even though the changes do not take effect until the 2027–28 income year.

What the Next Data May Show

Final auction results for the first weekend of October, future monthly housing data and the next round of lending statistics will provide a clearer picture of whether buyer Demand continues to weaken. The interaction between interest rates, available housing stock and investor tax settings is likely to remain important for market activity through the remainder of 2026.

Key Insights

The sub-50% preliminary auction clearance rate points to a more cautious housing market at the start of October 2026. Higher interest rates are affecting borrowing conditions at the same time that buyers have more properties to choose from. Upcoming tax changes for established investment property add another Factor that may influence demand, but the direction of the market will depend on how these pressures interact with housing supply, Credit conditions and subsequent auction results.
