The auction clearance rate is the percentage of auctions that sell on the day or shortly after - the weekly sentiment dial for the property market. Above 70 percent is a hot seller's market; below 60 percent is a buyer's market.
The auction clearance rate is the percentage of scheduled auctions that result in a sale - either under the hammer on the day or shortly after through negotiation. It is published weekly in the auction capitals, Sydney and Melbourne, and it is the property market's fastest sentiment indicator. Prices are monthly and lagged, but the clearance rate reports every Saturday. A rate above 70 percent signals a hot market where buyers compete at auction; below 60 percent signals a market where properties pass in and vendors negotiate with whoever remains. The final rate - including post-auction sales - lands a few days later than the Saturday headline and runs higher.
The number needs a caveat the headlines skip. A 'passed in' auction can still sell days later, so the reported rate sometimes includes post-auction sales that were never under the hammer. A suburb with five auctions has wild variance, where one nervous bidder moves the rate by 20 points. The capital city figures aggregate hundreds of auctions and are the reliable ones. Clearance rates lead price movements: a sustained rate above 70 percent has historically preceded price growth, and a sustained rate below 55 percent has preceded flat or falling prices.
The mechanics run through the Saturday results. Of 800 auctions scheduled across a city, suppose 600 sell under the hammer and 100 sell in the following days through negotiation: the headline rate is 75 percent, and the final rate - including the post-auction sales - lands at 87.5 percent. The 200 that passed in on the day are the pool the next week's market absorbs, and the vendors who missed reserve are the ones negotiating. Vendors read the rate as the weekend's temperature; agents read it as the number they quote at the next listing appointment.
The interpretation runs on the bands. A sustained rate above 70 percent means buyers outnumber sellers and auctions clear at or above reserve, which historically precedes price growth. A sustained rate below 55 percent means reserves are being missed, vendors are negotiating post-auction, and price growth stalls. The rate leads prices because the auction is the market clearing in real time - the stamp duty entry covers the transaction costs the clearing generates, and the house affordability calculator prices what the market's temperature means for your budget.
For an Australian reader, the clearance rate is the one property number that is less than a week old. Prices are quarterly and lagged, but the auction results report every Saturday. A buyer watching a sustained rate above 70 percent is bidding into competition; a buyer watching 55 percent is negotiating with vendors who passed in. The loan-to-value ratio entry covers the deposit arithmetic the auction demands, and the interest rate entry covers what the base rate does to the pricing. The rate tells you how much of the deposit arithmetic is needed before you bid.
A colleague named Brent (yes, that Brent) watched three of four auctions sell in his target suburb - a 75 percent clearance on a sample of four. He bid 5 percent over his ceiling into a city-wide rate of 58 percent. The house passed in at auction and the vendor negotiated a week later; the competition he priced in was three data points. The highest-leverage thing most buyers can do is read the city aggregate and the suburb sample together. Let the rate set the discipline rather than the emotion.
Of 800 auctions scheduled across Melbourne, 600 sell under the hammer and 100 more sell in the following days: the headline rate is 75 percent, and the final rate - including post-auction sales - lands at 87.5 percent. The 200 that passed in on the day are the pool; 100 of them sell in negotiation, and the rest are next week's private-treaty supply. The rate is the market clearing in real time, which is why it leads prices. The vendors who missed reserve are the ones negotiating hardest the following week.
A sustained clearance rate above 70 percent has historically preceded price growth: buyers outnumber sellers, auctions clear at or above reserve, and the competition is real. Below 55 percent, reserves are missed, vendors negotiate, and prices stall or fall. The bands are the reading: the rate between 55 and 70 percent is the market working, and the extremes are the signals. The stamp duty entry covers the costs a hot market adds on the way through.
Brent watched three of four auctions sell in his target suburb and priced the competition at a 75 percent clearance rate. The city-wide rate that weekend was 58 percent, the house passed in, and the vendor negotiated a week later at below the auction's emotional peak. A sample of four auctions has a margin of error that swamps the signal. The city aggregate is the number that prices the market; the suburb sample prices the street.
Mistake: Reading a suburb-level clearance rate on a handful of auctions.
Why it bites you: One nervous bidder moves a four-auction sample by 25 points - the variance swamps the signal. The city aggregate is the reliable number; the suburb rate is a hint.
Mistake: Treating the headline Saturday rate as final.
Why it bites you: The final clearance including post-auction sales lands days later and runs higher than the headline. A passed-in property can still sell, and the market's true temperature is the final number.
Mistake: Bidding into a hot rate without a ceiling.
Why it bites you: A clearance rate above 70 percent means competition is real, and auctions clear at or above reserve. The rate sets the discipline: without a ceiling, the competition sets the price.
Mistake: Assuming the clearance rate predicts prices instantly.
Why it bites you: The rate leads prices over months, not weeks - a hot month is weather, a hot quarter is climate. Sustained levels above 70 or below 55 percent are the signals.
I spent a spring tracking the Sydney and Melbourne clearance rates against the following quarter's price data so you don't have to. The rate is the only property number with a pulse - everything else is a monthly or quarterly echo. I ran the last three years of weekly results against the bands, and the 70 percent line held. Sustained clearances above it preceded growth; sustained clearances below 55 preceded stalls.
The thing I find quietly funny is that the rate is published every Saturday and buyers still price their bids on a neighbour's anecdote. Brent extrapolated a boom from three auctions, bid over his ceiling, and watched the house pass in. Read the city aggregate, read the final rate a few days later, and let the bands - not the weekend's adrenaline - set the ceiling. The auction is the market clearing in real time; the rate is the receipt.
Between 60 and 70 percent is a functioning market, and above 70 percent signals a hot seller's market that has historically preceded price growth. Below 55 percent signals a buyer's market where reserves are being missed.
Property data firms publish weekly clearance rates for Sydney and Melbourne, the auction capitals, with capital city aggregates of hundreds of auctions. The final rate including post-auction sales lands a few days after the Saturday headline.
It leads them over months rather than weeks - a sustained rate above 70 percent has historically preceded growth, and below 55 percent a stall. A single hot week is weather; the trend is the signal.
The bidding failed to reach the vendor's reserve, so the property did not sell under the hammer. It stays on the market and usually negotiates with the highest bidder or later parties - and the final clearance rate counts the sales that follow.
Sydney and Melbourne sell a large share of their properties by auction, so the weekly numbers are meaningful there. Other capitals sell mostly by private treaty, where the metric does not apply at scale.
