Purchasing a home at auction in Victoria can be fast-paced and competitive, but it is also a public sale governed by strict legal rules. Unlike a private sale, which allows for more controlled and less public negotiations, an auction creates a high-pressure environment where decisions must be made swiftly. Because of the transparency and competitive nature of the process, it is vital to understand the auction rules when buying property at auction in Victoria to avoid unnecessary legal complications.
How property auctions work in Victoria
An auction is generally conducted by an estate agent acting as an auctioneer at a specific time and place. The process typically follows a several-week advertising campaign that includes multiple open house inspections.
Auction conditions explained
By law, the auction contract in Victoria, the auction rules, and the information statement must be on display for at least 30 minutes before the bidding starts. It is critical to review these early, as by placing a bid, you are legally accepting the terms of the contract on display. Once the hammer falls, you will not be able to negotiate terms, such as requesting a longer settlement period, unless the seller has agreed to them in writing beforehand.
Before the bidding begins, the auctioneer is legally required to make several announcements, including that the auction will follow the established rules, that bids will not be accepted after the hammer falls, and that bidders must be identified upon request. They must also warn attendees that disrupting the auction or making false bids is illegal and carries substantial fines.

Vendor bids and reserve prices
The seller sets a reserve price, which is the minimum amount they are willing to accept. If bidding reaches or exceeds this price, the auctioneer will declare the property is ‘on the market’, and it will be sold to the highest bidder. If the reserve is not met, the property is ‘passed in’, and the highest bidder earns the first right to negotiate a price with the seller.
During the process, the auctioneer may make a vendor bid on behalf of the seller if they are unsatisfied with the current bid amount, provided this right was announced before bidding commenced. This must be clearly announced by the auctioneer when the bid is made. In contrast, ‘dummy bidding’, where false bids are made by non-genuine bidders to drive up the price, is illegal and attracts significant penalties.
Key legal differences between auction and private sale
The legal obligations for buying property at auction in Victoria are much more rigid than those of a private sale.
No cooling-off period
The most significant difference is that there is no cooling-off period when buying property at auction in Victoria. This means there is no option for a ‘change of mind’ once you are the successful bidder. Crucially, this rule also applies if your offer is accepted less than three clear business days before or after the scheduled auction date. In a private treaty sale, a holding deposit might be returned if a buyer changes their mind before exchange, but at an auction, the sale is binding immediately upon the fall of the hammer.
Unconditional contracts
When you buy ‘under the hammer’, the contract is unconditional. You are agreeing to the property in its current state, like it or not, regardless of whether you have thoroughly read the contract. You cannot make the contract “subject to finance” or “subject to a building inspection” after the auction has concluded.
Major legal risks buyers face at auction
Finance and valuation risks
A common risk when buying property at auction is assuming that a ‘pre-approval’ is a guaranteed loan. Pre-approval is subject to conditions, most notably the lender’s requirement for a satisfactory property valuation. If you are successful at the auction and the bank’s valuation comes in lower than the purchase price, the lender may reject the loan or offer a smaller loan amount. In this scenario, the buyer is legally obligated to bridge the financial gap or risk losing their entire deposit.
Deposit and settlement risk
Buyers will generally have limited remedies unless the damage involves misrepresentation, fraud, or a failure to disclose required information. Additionally, buyers must be wary of hidden easements or restrictive covenants in the Section 32 that could prevent them from extending the home or installing a swimming pool in the future. To help identify these issues, sellers must make the due diligence checklist available to prospective buyers, and buyers are strongly encouraged to review it carefully. The due diligence checklist highlights risk like owner’s corporation rules, and flood zones.

What happens if you win an auction?
Signing the contract
If you are the successful bidder, you must immediately sign the contract of sale to make your formal offer, which the seller accepts by also signing. The contract becomes binding immediately upon both parties signing on auction day.
Paying the deposit
Upon signing, you must pay the deposit specified in the contract, which is usually 10% of the purchase price. It is essential to confirm the accepted payment method (such as electronic transfer or bank cheque) with the agent beforehand.
To pay a partial deposit on auction day, you must get the seller’s written consent to amend the contract before the auction starts. By law, the deposit is held in a trust account by an agent or legal representative until settlement, unless you formally agree to an early release.
Prior to participating in a property auction in Victoria, obtain unconditional finance approval from your lender, not just pre-approval, as auction contracts are binding with no “subject to finance” clauses. Conduct a professional valuation of the property in advance to avoid post-auction discrepancies where the bank’s valuation falls short of your bid, potentially leading to loan rejection and loss of your deposit. This preparation mitigates the risk of financial penalties, including penalty interest or legal action if settlement fails.

What happens if a buyer can’t settle after auction?
Failing to settle is a breach of contract with severe financial and legal consequences.
Financial penalties
As the buyer if you cannot provide funds by the fixed settlement date you can always ask the seller for a penalty free extension. However, the seller may not agree and can potential issue a Notice of Default, typically providing 14 days to rectify the breach. During this delay, you may be charged penalty interest, commonly set at 12% per annum.
Legal consequences
If the buyer remains in default, the vendor can rescind the contract and retain the entire deposit. Furthermore, the vendor can sue the buyer for damages, which may include:
- The difference between your winning bid and the eventually achieved resale price;
- Any losses the vendor suffered if they were relying on your funds to purchase another property, and
- Legal fees incurred due to the breach.
- Expert Tip
Always review the Contract of Sale, Section 32 Vendor Statement, and due diligence checklist well before auction day, ideally with a solicitor or conveyancer, to identify hidden issues like easements, restrictive covenants, flood risks, or owners corporation rules that could impact your plans for the property. Negotiate any necessary amendments, such as settlement dates or deposit amounts, in writing prior to bidding, as changes are impossible after the hammer falls and the unconditional contract binds you immediately.
Why pre-auction contract reviews matter
Because the contract of sale cannot be changed after the auction, getting a professional contract review well before auction day is essential. A solicitor or conveyancer can identify hidden special conditions, such as costs associated with delaying settlement or other hidden costs which have not been disclosed by the selling agent upfront.
Furthermore, having the contract reviewed early allows your legal representative to negotiate amendments on your behalf before the auction starts, such as requesting a smaller deposit or a different settlement date. Combined with professional building and pest reports, a pre-auction review ensures you understand exactly what you are legally committing to before you put your hand up to bid.
