Auction vs Private Treaty in Brisbane: Which Suits Your Property?
If you’re preparing to sell your property in Brisbane, you may be deciding between auction and private treaty. The two methods differ in how buyers make offers, prices are communicated and contracts are negotiated.
This guide compares their advantages, costs and contract conditions to help you consider which approach may suit your property and selling plans.
Auction vs Private Treaty: What’s the Difference?
The main difference is how buyers make offers. At auction, registered bidders compete publicly at a scheduled event. With private treaty, the seller considers and negotiates individual offers, usually through a real estate agent.
How Does Selling at Auction Work?
The auction process begins with a marketing campaign leading to a scheduled event where an auctioneer invites registered bidders to compete for your property. Before auction day, you and your agent discuss the selling strategy and may set a reserve price in writing.
If bidding reaches the reserve and the property is sold under the hammer, the highest bidder signs the contract. Auction terms generally require buyers to complete relevant checks and arrange finance before bidding. There is no buyer cooling-off period for a sale at auction.
For more information about bidder registration, reserves and auction contracts, see the Queensland Government’s auction guidance .
How Does a Private Treaty Sale Work?
In a private treaty sale, also known as a private sale, interested purchasers submit offers for you to consider, usually through your agent. Your property may be advertised with an asking price or price range, and negotiations can cover the sale price, deposit, settlement date and contract conditions.
For example, a buyer may request conditions for finance approval or building and pest inspections. You can assess the offer as a whole and decide which terms you are willing to accept.

Selling at Auction: Pros and Cons
An auction provides a scheduled event and the possibility of competitive bidding when several interested buyers are prepared to participate.
However, some buyers may prefer to negotiate conditions rather than bid under auction terms. There is also no guarantee that bidding will reach your reserve, so it’s worth discussing a post-auction plan with your agent.
When Might an Auction Suit Your Property?
An auction may be worth considering when your property is expected to attract several buyers prepared to bid under the auction terms.
For example, a well-presented family home in Brisbane’s Inner West might attract multiple interested purchasers. Whether an auction suits that home will still depend on competing listings, likely buyers, price expectations and local market conditions.
A scheduled auction provides a clear focus for the campaign, but it does not guarantee a sale on the day.
What Happens If Your Property Is Passed In at Auction?
A property may be passed in when bidding does not reach the reserve price and it is not sold under the hammer.
If this happens, you and your agent can consider negotiating with interested buyers or reviewing the ongoing marketing strategy.
Cooling-off rules can differ for a post-auction sale. See the Queensland contract section below for the relevant exemptions, and seek advice from your solicitor or conveyancer before accepting an offer.
Selling by Private Treaty: Pros and Cons
Private treaty allows you to assess offers individually and negotiate terms that matter to you. These may include the purchase price, finance conditions, settlement arrangements or other agreed requirements.
This flexibility can be useful when potential buyers have different financial or moving circumstances. An offer with a higher price may also include conditions or a settlement date that you need to consider carefully.
On the other hand, there is no single scheduled bidding event. The length of the campaign depends on the interest received, the offers made and the decisions taken during negotiations.
A private treaty campaign can still attract competition between buyers, but offers are generally handled through individual negotiations rather than public bidding.
When Might a Private Treaty Sale Suit Your Property?
Private treaty may suit sellers who prefer to consider offers as they arrive and negotiate a combination of price, settlement arrangements and contract conditions.
For example, a buyer interested in a family home may need time to arrange finance or a building and pest inspection. You can consider those conditions alongside the offered price and other terms.
A property appealing to a smaller or more specialised buyer pool may also benefit from a campaign that allows individual enquiries and negotiations to develop over time.
How to Choose Between Auction and Private Treaty in Brisbane
The choice between auction and private treaty should start with your property and your selling priorities, rather than an assumption that one method always achieves a better result.
Consider what comparable homes have recently sold for, who is likely to be interested in yours, how those buyers may prefer to purchase and what flexibility you need around your sale.
Property Type and Likely Buyer Pool
Think about the buyers your property may attract and what they are likely to need before making an offer.
For example, a family home in Ashgrove, a character property in Paddington and a townhouse in Alderley may appeal to different buyer groups. Property condition, price range, size and features can influence both the level of interest and how prepared prospective buyers are to proceed.
If several buyers are expected to be ready to bid under auction terms, a public bidding event may be considered. If buyers are more likely to seek negotiated conditions, private treaty may provide a suitable framework for assessing their offers.
These are possibilities to discuss with your agent, not rules that apply to every property in a particular suburb.
Local Market Conditions and Buyer Interest
Conditions in the local property market, including demand and competing listings, can affect either sale method.
Where multiple buyers are actively seeking similar homes, a scheduled bidding event may bring that interest together. In a quieter market, a seller may prefer the flexibility of reviewing individual offers without relying on a particular auction day.
However, market conditions alone should not determine your strategy. A property can attract strong interest in a quieter market or receive fewer enquiries than expected when broader demand is high.
Ask your agent to review recent comparable sales, competing listings, inspection feedback and the interest shown in properties similar to yours.
Price Guidance, Campaign Costs and Selling Timeline
Before choosing a method, discuss your property’s market position and proposed pricing strategy with your agent.
For an auction, this includes understanding the reserve-price process and Queensland’s restrictions on disclosing auction price guides to prospective buyers. For private treaty, it includes discussing an appropriate advertised price or price range and the strategy for reviewing offers.
Request an itemised marketing proposal so you can compare the activities and fees associated with each approach. An auction may involve an auctioneer’s fee and event-specific advertising, while a private treaty campaign also has agreed marketing and selling expenses.
Consider your preferred moving and settlement dates as well. An auction date is not the same as settlement, and neither method guarantees that your property will sell within a particular number of days.
Queensland Contract Conditions and Seller Disclosure Requirements
Regardless of your chosen selling method, it’s important to understand the contract requirements before launching a campaign.
The following is a general overview for residential sellers. Your solicitor or conveyancer can explain how the rules apply to your property and proposed contract.
Cooling-Off Periods and Conditional Offers
In Queensland, eligible residential buyers generally receive a five-business-day cooling-off period under a private treaty contract. The period begins when the buyer receives the contract signed by both parties, subject to the rules for weekends and public holidays.
Auction sales are exempt from the cooling-off period. A follow-up sale after an unsuccessful auction is also exempt if the buyer was a registered bidder and the contract is entered into before 5 pm on the second business day after the auction. Other exemptions apply, and an eligible buyer may waive or shorten the cooling-off period in writing.
Cooling-off rights are separate from negotiated contract conditions. A finance or building and pest condition, for example, operates according to the terms agreed in the contract; it is not the same as a cooling-off period.
You can review the exceptions and timing requirements in the Queensland Government’s residential cooling-off guidance .
Seller Disclosure Requirements for Auctions and Private Treaty
Queensland’s seller disclosure scheme commenced on 1 August 2025. Subject to applicable exemptions, sellers must provide buyers with a completed Form 2 seller disclosure statement and the prescribed certificates relevant to the property.
For a private treaty sale, the required documents must be given to the buyer before they sign the contract. Different rules apply at auction. Buyers who register to bid before the auction starts must generally receive the disclosure documents before it begins. Separate rules apply to bidders who register after the auction has started, including requirements for making the documents available.
The documents required and the way they must be provided depend on the property and the circumstances of the sale. Engage your solicitor or conveyancer early to prepare the relevant information and confirm the appropriate disclosure process.
See the Queensland Government’s seller disclosure guidance for an overview of the requirements and exemptions.
Frequently Asked Questions
Does Selling at Auction Always Achieve a Higher Price?
No. Neither auction nor private treaty guarantees a higher sale price.
The outcome depends on factors such as the property’s characteristics, buyer interest, competing listings, local market conditions and the offers received.
Public bidding may create competition when several buyers are prepared to bid, but this does not guarantee that the final price will exceed what might have been negotiated through private treaty.
Can You Set a Reserve Price at Auction?
Yes. You may set a reserve price in writing with your agent before the auction. This is the minimum price you agree to accept under the auction terms.
Queensland’s rules restrict the disclosure of the reserve and auction price guides to prospective buyers. These restrictions do not prevent you from discussing comparable sales, pricing expectations and reserve strategy with your agent.
If bidding reaches the reserve and the property is declared on the market, the auction proceeds towards a sale under its terms.
Is Selling at Auction More Expensive Than Private Treaty?
Not necessarily. The overall cost depends on the agreed agency fees, advertising package and activities included in your campaign.
An auction may involve an auctioneer’s fee and event-specific expenses. A private treaty campaign can also involve substantial marketing costs.
Ask your agent for an itemised proposal and compare what is included, rather than assuming one method will always cost more.
Can You Change Selling Methods if Your Property Doesn’t Sell?
You may be able to change your strategy after an unsuccessful auction. For example, you and your agent might continue negotiating with interested buyers or market the property through private treaty.
The next steps will depend on your agency agreement, existing campaign arrangements and any contractual obligations. Discuss your options with your agent and obtain legal advice where needed before making changes.
