Sydney owners are seeing a more selective market on both sides of the transaction. Rental availability increased in September. Separately, SQM’s asking-rent figures for the 30 days to 12 October showed unit rents easing while house rents rose. In sales, the post-long-weekend auction result was weaker even as volumes recovered.
The practical message is consistent. A city-wide headline is useful context, but the next decision should come from the competing stock, enquiry quality and documented evidence around the individual property.
Sydney vacancy rose to 1.8%
SQM Research reported a Sydney residential vacancy rate of 1.8% for September, up from 1.7% in August and 1.3% a year earlier. The number of available rental dwellings increased to 13,331.
This is a meaningful easing in availability, particularly when compared with last year, but 1.8% is not a broad oversupply signal. The more useful conclusion for landlords is that tenants have more choice and are more able to compare presentation, price and lease terms.
For a current campaign, track direct competing listings, qualified enquiry, inspection attendance, applications and days on market. A rent that looks strong on paper can produce a weaker annual outcome if it creates an avoidable vacancy.
House and unit asking rents moved in different directions
Over the 30 days to 12 October, Sydney’s combined advertised rent rose 0.7% to $915.61 per week. Underneath that headline, house asking rents rose 2.3% to $1,159.28, while unit asking rents fell 1.0% to $749.18.
These are advertised rents, not achieved rents for every property. Even so, the divergence matters: owners should not apply a single city-wide growth assumption across houses and apartments. Unit campaigns need especially close comparison with current local competition, while house performance still depends on location, condition, accommodation and the depth of the relevant tenant pool.
Sydney’s final auction clearance rate fell to 45.6%
Cotality’s final result for the week ended 11 October recorded 632 Sydney auctions and a 45.6% clearance rate. The volume more than doubled from the long-weekend total of 299, but the clearance rate fell 3.7 percentage points from 49.3%.
Compared with the same week in 2025, auction volume was 36.0% lower and the clearance rate was 22.6 percentage points lower. For the week ending 18 October, 688 Sydney auctions were scheduled—8.9% above the prior week but 36.2% below a year earlier.
This is a clearer signal than the holiday-affected result. Buyer demand remains cautious, and the combined-capital clearance rate has now declined for four consecutive weeks. Sellers should use inspection feedback, contract requests, written offers and price-guide engagement to decide whether the auction path is still creating competition.
Termination records are receiving closer scrutiny
NSW released the first results from its mandatory End of Tenancy Survey on 8 October. More than 275,000 landlord and agent responses were collected, covering around 90% of bonds refunded during the reporting period. The government reported that about 85% of tenancies were ended by renters.
Where a landlord ended the tenancy, the leading reasons included the owner or a family member moving in (28%), a proposed sale (20%) and an actual sale (14%). NSW says its Rental Taskforce cross-checks stated termination reasons against rental listings and bond lodgement data.
For owners and agents, the implication is operational: use the correct lawful ground, retain the supporting evidence and observe any re-letting exclusion period. The stated reason and subsequent property activity need to be consistent.
Rates remain a cash-flow constraint
The RBA cash rate target remains 4.60%, effective from 30 September, with the next monetary policy decision due on 3 November. Investors should check the actual rate and repricing date on each loan rather than treating the cash-rate headline as the portfolio’s borrowing cost.
Owner Takeaway
Sydney’s vacancy rate rose to 1.8% in September. Over the 30 days to 12 October, unit asking rents fell 1.0% while house asking rents rose 2.3%. Price each property against its direct competition and compare the cost of a vacancy with the benefit of holding out for a higher rent. For sellers, a 45.6% final clearance rate across 632 auctions confirms that buyers remain selective. If ending a tenancy, keep the lawful reason, evidence, notices and subsequent re-letting activity aligned.
