Auction Clearance Rates Explained: What This Key Market Indicator Tells Property Investors in Australia

If you've ever watched property market news, you'll have heard auction clearance rates mentioned as a barometer of market health. Weekend reports breathlessly announce that "Sydney recorded a 72% clearance rate" or "Melbourne's clearance rate dropped below 60%." But what do these numbers actually mean, how are they calculated, and — most importantly — should they influence your investment decisions?

This guide breaks down everything you need to know about auction clearance rates: how they're measured, what they tell you (and what they don't), and how to use them alongside other data when evaluating property markets in Australia.

Key Takeaways

• Auction clearance rates measure the percentage of properties that sell at or before auction on a given weekend, with rates above 70% generally indicating a strong seller's market
• The preliminary clearance rate reported on Saturday evening is typically 5–8 percentage points higher than the revised rate published the following week
• Clearance rates vary dramatically by city — Sydney and Melbourne auction over 30% of sales, while Brisbane and Perth auction fewer than 15%
• According to Picki data, suburbs with consistently high clearance rates often correlate with strong demand fundamentals including low vacancy rates and above-average population growth
• Clearance rates are a lagging indicator of buyer sentiment, not a predictor of future price movements

What Is an Auction Clearance Rate?

An auction clearance rate is the percentage of properties that sold at auction on a given weekend, out of the total number of properties that were scheduled or reported to be auctioned. The calculation is straightforward:

Clearance Rate = (Properties Sold at Auction ÷ Total Properties Scheduled for Auction) × 100

A property is counted as "sold" if it sells under the hammer at auction, or if it sells prior to the scheduled auction date. Properties that are passed in (fail to meet the reserve price) or are withdrawn from auction before the event are counted in the denominator but not as sales.

For example, if 800 properties were scheduled for auction on a Saturday in Sydney and 576 of them sold (either under the hammer or prior), the clearance rate would be 72%.

How Clearance Rates Are Collected and Reported

Understanding the reporting timeline matters because the numbers change significantly between the preliminary and final figures.

Preliminary vs. Revised Rates

On Saturday evening, data providers like CoreLogic and Domain publish preliminary clearance rates based on the results they've collected so far. These preliminary figures are always incomplete — not all agents have reported their results yet, and some auctions are still in progress or negotiating post-auction.

The revised clearance rate, published the following Wednesday or Thursday, includes a much larger sample of reported results. Historically, the revised rate is 5–8 percentage points lower than the preliminary figure. So a preliminary clearance rate of 75% on Saturday might settle at 68–70% once all results are in.

This matters because media headlines typically report the preliminary figure — the one that makes the market look stronger than it actually performed. Savvy investors always wait for the revised number.

Who Reports and How

CoreLogic and Domain are the two primary sources of auction clearance data in Australia. Both rely on agents voluntarily reporting their results. There's a well-known reporting bias: agents who achieved a sale are more likely to report promptly than agents whose properties passed in. This creates a systematic upward bias in preliminary figures.

Neither source captures 100% of auctions. CoreLogic typically achieves a reporting rate of 85–90% for revised figures in Sydney and Melbourne, but coverage drops in smaller markets. This means clearance rates for cities like Brisbane, Adelaide, or Canberra should be interpreted with more caution — smaller sample sizes make them more volatile.

What Different Clearance Rate Levels Mean

While there's no magic number that defines a "good" or "bad" clearance rate, decades of market data suggest some useful benchmarks:

Above 75%: Strong seller's market. Properties are attracting multiple bidders, selling above reserve, and vendors have significant pricing power. In these conditions, prices typically rise.

65–75%: Balanced to moderately strong market. Properties are generally selling, but buyers have some negotiating room. Price growth tends to be moderate.

55–65%: Balanced to softening market. A meaningful proportion of properties are passing in. Buyers have more power, and vendors may need to adjust expectations.

Below 55%: Buyer's market. Sellers are struggling to achieve their reserve prices, many properties are passing in, and vendors may shift away from auction as a selling method. Prices are likely flat or declining.

For property investors, understanding where your target market sits on this spectrum helps contextualise other data points. A suburb showing strong rental yields in a market with sub-55% clearance rates may represent a buying opportunity — or it may signal deeper demand problems that require investigation.

Why Clearance Rates Vary by City

One of the most misunderstood aspects of auction clearance rates is that they're not comparable across cities. The auction culture varies dramatically between Australian capitals:

Melbourne is Australia's auction capital. Approximately 30–35% of all residential sales in Melbourne go to auction. The city has a deep auction culture, and clearance rates are a genuinely useful market barometer because the sample size is large enough to be statistically meaningful.

Sydney also has a strong auction culture, with roughly 25–30% of sales occurring at auction. Sydney's clearance rate is the second-most reliable capital city indicator.

Brisbane, Perth, and Adelaide have much lower auction rates — typically 10–15% of sales. In these markets, clearance rates are based on smaller samples and are less reliable as market indicators. A single weekend with a handful of high-profile auctions can skew the numbers significantly.

This means comparing Sydney's 72% clearance rate with Brisbane's 45% clearance rate is misleading. Brisbane might have a perfectly healthy market — it's just that fewer properties go to auction, and the ones that do are often higher-end or unusual properties that face different demand dynamics.

For investors analysing markets like Blacktown in Sydney versus Point Cook in Melbourne, understanding the local auction culture helps you interpret the numbers correctly rather than making apples-to-oranges comparisons.

What Clearance Rates Tell You (and What They Don't)

What They're Good For

Measuring buyer sentiment in real time. Clearance rates are one of the few property market indicators that update weekly. While most property data (median prices, rental yields, vacancy rates) is published monthly or quarterly, clearance rates give a near-real-time read on how confident buyers are feeling.

Tracking momentum shifts. A clearance rate that drops from 75% to 62% over four consecutive weekends tells you something meaningful is changing in buyer behaviour — even before it shows up in price data. Conversely, rising clearance rates often precede price increases by 2–3 months.

Identifying seasonal patterns. Auction clearance rates exhibit strong seasonal patterns. Spring (September–November) typically sees the highest volumes and strongest clearance rates. January and early February are quiet. Mid-year is moderate. Understanding these patterns prevents you from misinterpreting seasonal noise as a market trend.

What They Can't Tell You

They don't measure private treaty sales. The majority of Australian property sales occur via private treaty (negotiated sale), not auction. Clearance rates tell you nothing about this larger portion of the market. A declining clearance rate might simply mean vendors are shifting to private treaty rather than the market weakening overall.

They're a lagging indicator. By the time clearance rates reflect market weakness, the conditions causing that weakness — rising interest rates, reduced borrowing capacity, employment concerns — have typically been in play for weeks or months. Clearance rates confirm what's already happening; they don't predict what's coming next.

They don't tell you about price. A property that sells at auction for $50,000 below the vendor's expectations still counts as a "sale" in the clearance rate. High clearance rates don't necessarily mean vendors are achieving strong prices — only that transactions are occurring.

How to Use Clearance Rates in Your Investment Research

Rather than treating clearance rates as a standalone signal, experienced investors use them as one input alongside other market data. Here's a practical framework:

1. Track trends, not single weekends. One weekend's clearance rate is noisy. Look at the four-week rolling average to identify genuine shifts in market momentum. A sustained move above 70% or below 60% is far more meaningful than a single outlier weekend.

2. Compare like with like. Only compare clearance rates within the same city, and ideally within the same season. Comparing Melbourne's spring clearance rate with its winter rate is more useful than comparing Melbourne with Perth.

3. Cross-reference with other demand indicators. Clearance rates gain more predictive power when combined with other data. A rising clearance rate plus declining vacancy rates plus strong cashflow fundamentals tells a much stronger story than any single metric alone.

4. Use them to time your negotiating strategy. In a market with sub-60% clearance rates, you have more leverage as a buyer. Properties that pass in at auction often sell within the following two weeks at a discount of 5–10% below the highest auction bid. In contrast, markets above 75% require buyers to be prepared, pre-approved, and decisive.

5. Don't ignore the volume. A 90% clearance rate from 50 auctions is less meaningful than a 70% clearance rate from 500 auctions. Always check the total number of scheduled auctions alongside the rate itself. Low-volume weekends produce volatile, unreliable clearance rates.

Clearance Rates and Property Investment Strategy

For long-term property investors, auction clearance rates are useful context but should never be the primary driver of investment decisions. Properties held for 10–20 years will inevitably experience multiple market cycles. The suburb-level fundamentals — population growth, employment diversity, infrastructure investment, and rental demand — matter far more than whether this Saturday's clearance rate was 68% or 74%.

That said, clearance rates can help with timing. According to Picki's analysis, investors who purchase during periods of lower clearance rates (below 60%) in fundamentally strong suburbs tend to achieve better entry prices. The key is identifying suburbs where temporary market softness (reflected in clearance rates) doesn't reflect a change in the underlying demand story.

Picki data shows that suburbs with consistently strong fundamentals — low vacancy rates, diversified employment bases, and sustained population growth above the national average — tend to recover faster after periods of market softness. Suburbs like Kirwan in Townsville and Tarneit in Melbourne's west demonstrate how strong underlying demand can persist through market cycle fluctuations.

Frequently Asked Questions

What is a good auction clearance rate for buyers?

Buyers generally have more negotiating power when clearance rates are below 60%. In these conditions, a higher proportion of properties pass in at auction, creating opportunities to negotiate post-auction. Clearance rates above 75% indicate strong competition where buyers need to be well-prepared and may face bidding wars.

Why is the preliminary clearance rate always higher than the revised rate?

The preliminary rate reported on Saturday evening is based on incomplete data. Agents who achieved a sale are more likely to report results quickly, creating a systematic upward bias. The revised rate, published mid-week with more complete data, is typically 5–8 percentage points lower. Always use the revised rate for analysis.

Are auction clearance rates relevant in Brisbane and Perth?

Less so than in Sydney and Melbourne. Brisbane and Perth have lower auction volumes (10–15% of sales vs. 25–35% in Sydney and Melbourne), which means the sample size is smaller and the rates more volatile. In these markets, private treaty listing volumes, days on market, and vendor discounting provide more reliable market indicators.

Can clearance rates predict property price changes?

Clearance rates are a concurrent to slightly lagging indicator, not a predictor. However, sustained trends in clearance rates — such as four or more consecutive weeks above 75% or below 55% — have historically preceded corresponding price movements by 2–3 months. They're best used as confirmation of market direction rather than a forecasting tool.

How do interest rate changes affect auction clearance rates?

Interest rate increases typically reduce clearance rates within 4–8 weeks as borrowing capacity contracts and buyer confidence falls. The RBA's rate increases from May 2022 through late 2023 saw clearance rates in Sydney and Melbourne drop from above 75% to below 55%. Conversely, rate holds or cuts tend to support or lift clearance rates as buyer confidence recovers.
