Last week the preliminary auction clearance rate across the combined capitals climbed to its highest level in eleven weeks, and a fair chunk of the property press treated it as the first green shoot of the spring. I'd hold off on the celebration. The clearance rate isn't rising because more homes are selling well. It's rising because the vendors most likely to produce an embarrassing result have quietly stopped turning up.
That's not a conspiracy — it's arithmetic. The clearance rate is a percentage, and percentages are only as honest as the pool they're drawn from. Right now three separate filters are stripping the weakest results out of that pool before anybody counts them.
Filter one: the vendors who never book an auction at all
This is the big one, and it's had almost no coverage. According to Cotality, the share of new listings taken to auction has collapsed from close to 45% in November 2025 to just above 30% by June 2026. The long-run average sits near 28%, so we've gone from an unusually auction-heavy market back to the floor in roughly seven months.
Gerard Burg, Head of Research at Cotality Australia, put the logic plainly: "During times of strong demand, vendors clearly favour auctions as competition between multiple bidders can result in a higher price." They have, he noted, "been shying away more recently in this weaker demand environment."
Crucially, Cotality found auction numbers in Sydney and Melbourne have fallen more steeply than the overall decline in new listings. That rules out the comfortable explanation. This isn't fewer people selling — it's the same people selling differently.
Filter two: the auctions that get pulled before auction day
Of the campaigns that do get booked, an unusual number never make it to the hammer. The withdrawal rate averaged 11.8% across 2025. Through mid-2026 it has run between roughly 17% and 24%, peaking near a quarter of all scheduled auctions in the week ending 21 June.
Cotality's head of research Tim Lawless tracked the swing: "Withdrawn auctions rose to 24% ... but have since reduced back to 17.4% this week." Withdrawn auctions are excluded from the clearance calculation entirely. Every campaign pulled because it was heading for a passed-in result is a bad number that simply never gets recorded.
Filter three: Sydney's quiet pre-auction market
Sydney shows the third filter most clearly. In the week ending 26 July, Sydney posted a respectable-looking 56.1% clearance from 433 auctions. Underneath it: a withdrawal rate around 30%, and 63.4% of the successful results were deals done before auction day.
So the "auction market" that produced that 56.1% was, for the most part, not an auction market. It was private negotiation wearing an auction's clothes — vendors taking a certain offer on Wednesday rather than risking silence on Saturday. Sydney auctioneer Tom Panos, three decades in the job, has been describing back-to-back weekends with zero registered bidders and calling conditions the weakest he's seen since 1991.
What the unfiltered numbers actually say
Strip the flattery away and the picture is consistent. In the week ending 2 August, the combined capitals finalised at 48.9% — down from 67.1% in the same week a year earlier, a fall of 18.2 percentage points. Volumes came in at 1,257 auctions against 1,575 a year ago. Cotality noted every capital city is now holding below its decade-long average.
City by city, the spread is wide: Melbourne 54.7%, Adelaide 45.7%, Sydney 45.6%, Canberra 43.4%, and Brisbane at 37.5% — which has now spent nine consecutive weeks below 40%, in the city that spent five years being sold as the affordable escape route.
Meanwhile total listings are running about 20% higher than a year ago, and the median vendor discount across the combined capitals has widened to roughly 3.6%. More stock, softer prices, fewer auctions. Those three facts belong together, and none of them are visible in the headline clearance number.
What this actually means if you're buying
The practical consequence is that the opportunity has moved house. If you've been watching clearance rates to time your run, you've been watching the shrinking end of the market.
- Spend your Saturdays differently. Roughly 70% of new listings are now private treaty. That's where the stock is, and it's where there's no crowd, no deadline and no auctioneer working the room.
- Treat a withdrawn auction as a lead, not a dead end. A campaign pulled last weekend is a motivated vendor with a property still to sell and no public deadline left to hide behind.
- Ask when the campaign started. Days on market is doing the work the clearance rate used to do. A listing that has quietly rolled over from an auction campaign into a private treaty has more history than the ad suggests.
- Have your finance genuinely settled first. Pre-auction offers are won on certainty as much as price. An unconditional buyer with formal approval beats a higher offer that's still waiting on a lender. Our borrowing power estimator is a starting point, but a real approval is the thing that closes these deals.
- Re-check your number before you offer. Three rate rises this year have moved borrowing capacity meaningfully. The budget you were approved for in February is not the budget you have in August.
None of this says the market is about to turn. It says the single statistic most buyers use to read the market has quietly become the least reliable one in the set — and the buyers who understand why are shopping somewhere less crowded.
Frequently Asked Questions
What is a good auction clearance rate in Australia?
A clearance rate above 70% generally signals a strong seller's market, 60-70% is balanced, and below 60% indicates weak conditions. In the week ending 2 August 2026 the combined capitals finalised at 48.9%, down 18.2 percentage points from 67.1% a year earlier, with every capital city sitting below its decade average.
Why is the auction clearance rate rising if the property market is falling?
Because the pool being measured has shrunk. Vendors likely to fail are increasingly not going to auction at all, withdrawing before auction day, or selling privately beforehand. The clearance rate only counts properties that reach the hammer, so removing the weakest campaigns lifts the percentage without the market improving.
What is an auction withdrawal rate and why does it matter?
The withdrawal rate is the share of scheduled auctions pulled before auction day. It averaged 11.8% across 2025 but has run between 17% and 24% through mid-2026, reaching about 30% in Sydney in late July. Withdrawn auctions are excluded from the clearance rate, so a high withdrawal rate flatters the headline figure.
Are more Australian homes selling by private treaty in 2026?
Yes. Cotality data shows the share of new listings taken to auction fell from close to 45% in November 2025 to just above 30% by June 2026, against a long-run average near 28%. Vendors are choosing private treaty to avoid the risk of a publicly failed campaign.
Is it better to buy at auction or by private treaty in a weak market?
In a weak market private treaty typically offers more room to negotiate, because there is no public deadline and no competing bidders in the room. Most stock now sits in private treaty campaigns, and the median vendor discount across the combined capitals has widened to around 3.6%.
