Auction vs private treaty: which method of sale suits your property

The method of sale is the second decision you make after choosing an agent, and a good agent will have a firm view. The right answer depends on your property, your suburb's habits and the state of the market in the month you list. This guide explains how each method works, what the current data says, and the questions that decide it.

How each method works

Private treaty (also called private sale) is the default across most of Australia. The property is advertised with a price, a range or "contact agent", buyers make offers through the agent, and you negotiate until you accept one. Contracts are exchanged or signed, and in most states the buyer then has a short cooling-off period: five business days in New South Wales and Queensland with a penalty of 0.25 per cent of the price if they withdraw, and three business days in Victoria with a penalty of $100 or 0.2 per cent, whichever is greater, according to Canstar's state summary. Check your state's regulator for current terms; the Victorian figure in particular is reported differently by some sources.

Auction is a public sale on a set date after a marketing campaign, usually three to four weeks. Buyers bid openly, the property is sold to the highest bidder if the reserve is met, and the contract is unconditional on the fall of the hammer. There is no cooling-off period for a buyer at auction. If bidding stops short of the reserve the property is "passed in" and the agent negotiates with the highest bidder first, then the market, usually that afternoon.

A third option, expressions of interest or a fixed-date sale, invites written offers by a deadline and then negotiates. It is common for prestige and unusual properties and borrows the campaign discipline of an auction without the public bidding.

What the 2026 data says

Auctions concentrate in Sydney, Melbourne, Canberra and Adelaide. Brisbane and the rest of Queensland, Perth and regional Australia sell mostly by private treaty. Cotality's long-run average for the auction share of new capital-city listings is around 28 per cent; the share climbed to nearly 45 per cent in November 2025 and fell to just over 30 per cent by June 2026 as the market softened (Cotality, monthly housing chart pack July 2026). An older RP Data estimate put auctions at about 19 per cent of all capital-city sales, with the rest sold by private treaty (Property Update).

Clearance rates tell you how the method is performing right now. For the week ending 11 October 2026 Cotality reported a combined-capitals final clearance rate of 44.1 per cent, against 68.2 per cent in the same week of 2025. Melbourne cleared 49.8 per cent of 703 auctions, Sydney 45.6 per cent of 632, and Brisbane only 21.8 per cent of 197, close to an 18-year low (Cotality, final clearance rates week ending 11 October 2026). Domain has reported that more than half of auction-launched listings across the five main auction cities were converting to private treaty during 2026 (Property Update).

The lesson is not that auctions are bad. It is that auctions work when there are several motivated buyers competing on the day, and in late 2026 there often are not. Check the clearance rate for your city in the fortnight before you decide, not the figure from last spring.

When an auction suits

• Hard-to-price properties. Unique homes, development sites, deceased estates and anything with no close comparables. The market sets the price in public.
• Strong buyer depth. Suburbs with consistent clearance above about 60 per cent and multiple registered bidders per auction.
• A need for certainty on a date. The unconditional contract on the day suits vendors who have bought elsewhere or need to settle by a deadline.
• A rising market. Competition on the day captures price growth that a fixed asking price would leave behind.

When private treaty suits

• Markets with thin demand. When clearance rates sit under 50 per cent, an unsuccessful auction can mark the property as stale.
• Properties with a clear price. A three-bedroom house in a street with five recent comparable sales does not need an auction to find its value.
• Buyers who need finance conditions. Many buyers cannot bid unconditionally. Private treaty lets them make conditional offers and widens the pool.
• Vendors who want privacy or flexibility. No public reserve, no public result if the campaign is slow, and the ability to adjust the price quietly.

Costs and risks

An auction campaign carries an auctioneer's fee, commonly around $600 to $1,000 according to LocalAgentFinder's 2026 selling costs guide, and usually a larger, front-loaded marketing spend because the campaign is compressed into four weeks. If the property passes in, that spend is sunk and the subsequent private treaty campaign starts with a public "passed in" result attached. In Victoria, the reserve must now be published at least seven days before the auction for sales from 16 October 2026 (Consumer Affairs Victoria), which removes the old practice of setting the reserve on the morning.

Private treaty's risk is the opposite: no deadline. An overpriced private treaty listing can sit for months, and days on market is the metric buyers watch most closely. Our guide to how long a sale takes covers what a realistic campaign looks like.

Questions that decide it

Ask your agent, and compare the answers between the three agents you interview:

1. What proportion of your sales in this suburb in the past year were by auction, and what was your clearance rate?
2. What was the clearance rate for this suburb or region last month?
3. How many registered bidders did your last three auctions here attract?
4. If we go to auction and pass in, what is the plan for the following week?
5. If we go private treaty, what is the offer deadline and what happens if we have no offers at the four-week mark?

An agent who answers with numbers is giving you advice. One who answers with a preference is giving you their business model.

Compare agents near you

Our suburb pages show each ranked agent's sales by method, so you can see who actually runs auctions in your suburb and how their results compare. The auction share and median days on market for the suburb appear in the market snapshot on each page, with the date the data was last updated.

Frequently asked questions

Is an auction better than private treaty?+

Neither is better in general. Auctions suit hard-to-price properties in markets with deep buyer demand; private treaty suits properties with clear comparables and markets where clearance rates are under about 50 per cent.

What is a good auction clearance rate?+

Above 60 per cent generally indicates a market where auctions are working. For the week ending 11 October 2026 the combined capitals cleared 44.1 per cent, with Brisbane at 21.8 per cent.

Is there a cooling-off period at auction?+

No. A buyer who wins at auction signs an unconditional contract on the day. Cooling-off periods apply only to private treaty contracts, and the terms vary by state.

What happens if my property passes in?+

The agent negotiates with the highest bidder first, then with other interested parties, usually the same day. If no sale results, the campaign typically converts to private treaty.
