Auctions vs Private Treaty — What Buyers Need to Know
In Australia, residential properties are typically sold via two main methods: auction or private treaty. Each has its own rules, advantages, and risks, so understanding how they work and how the process may differ depending on the state you're buying in is important.
What is a Private Treaty Sale?
A private treaty sale is the most common method, especially outside of capital cities. The seller sets an asking price (or price guide), and interested buyers make offers directly to the agent. There's room for negotiation on price, terms, and settlement dates.
Benefits of private treaty
- More time to conduct inspections and review the contract
- Flexibility to include conditions (e.g. subject to finance, building and pest)
- Cooling-off period in most states
Risks
- Sellers can still reject your offer or negotiate with other buyers at the same time
- Properties may be underquoted or priced to attract interest, so due diligence is key
What is an Auction?
An auction is a public sale — held in person or online — where prospective buyers place bids in real time. The highest bidder wins the property, provided the reserve price is met.
Key features of auctions
- Bidding is unconditional — you must have finance ready and complete inspections beforehand
- No cooling-off period applies (in most states)
- If you win, you must sign the contract and pay a deposit (usually 10%) on the spot
- If the property is passed in (doesn't meet reserve), the highest bidder may be invited to negotiate privately afterwards
Benefits of auctions
- Can be quicker and more transparent
- You see who you're competing against
- If you're prepared and confident, you may secure a good deal
Risks
- High-pressure environment — easy to overbid
- No time to include conditions or change your mind
- If you're not successful, you may lose money spent on pre-auction inspections or legal reviews
State-Specific Nuances
NSW
- No cooling-off period applies at auction or contracts entered into on auction day after the property is passed in
- Private treaty sales come with a 5-business-day cooling-off period (unless waived), with limited exceptions (e.g. non-residential land, certain large rural landholdings, and vacant land used for non-residential purposes)
- Gazumping is a risk in private treaty if the contract hasn't been exchanged
QLD
- No cooling-off at auction
- Unable to negotiate the inclusion of conditions such as subject to finance or inspection
VIC
- Auctions or contracts entered into within 3 days before or after a public auction come with no cooling-off
- Private treaty offers a 3-business-day cooling-off period from when the purchaser signs the contract, with limited exceptions (industrial/commercial property, farming properties over 20 hectares, repeat contracts within the same terms, or where the buyer is an estate agent or corporate body)
- If the property is passed in at auction, negotiations usually begin immediately with the highest bidder
Which Option is Right for You?
It depends on your risk appetite and level of preparation. If you need time to sort finance or want to include conditions, a private treaty may be safer. If you're well-prepared and confident, auctions can deliver quicker results.
At Zettle, we recommend always having your contract reviewed — regardless of the sale type — and being clear on your budget, conditions, and obligations before making an offer or raising your paddle.
