Buying at auction: what survives the hammer.
Auctions in Victoria are unconditional and offer no cooling-off period. A comprehensive buyer's guide to due diligence, bidding, deposit, finance and everything that must be completed before the hammer falls.
Buying at auction in Victoria is an unconditional purchase. There is no cooling-off period. The successful bidder is legally bound to buy on the fall of the hammer — usually with no finance clause, no inspection clause, and no opportunity to "add conditions later". Everything that protects the buyer must be done before the auction, not on the day.
This guide explains what a buyer should do before bidding, how auctions are conducted in Victoria, what happens if the property is passed in, when the transaction becomes binding, and what happens if the buyer cannot settle.
Auction day is not the start of the process. It is the end of it.
Why preparation must be completed before auction day
An auction contract is generally unconditional. Under the Sale of Land Act 1962 (Vic) and Consumer Affairs Victoria guidance, the three clear business days cooling-off period does not apply to a property bought at, or within three clear business days before or after, a publicly advertised auction. The buyer cannot add a finance clause, a due-diligence clause, a subject-to-inspection clause or any other protective condition after they have won.
Every legal, financial and physical enquiry that matters must therefore be completed before the auction. This includes the contract, the Section 32, finance, inspections, insurance, ownership structure, purchaser identity and — where relevant — foreign investment approval.
Reviewing the contract and Section 32 before bidding
The vendor's Section 32 statement must be available for inspection before the auction, and the contract of sale should be reviewed in the same sitting. A property lawyer or conveyancer should be engaged before the auction to read both documents and explain their combined effect.
The review should identify anything unusual — special conditions, non-standard deposit terms, extended settlement, adjustments beyond the standard general conditions, sunset dates for off-the-plan, land tax adjustment clauses, or GST provisions in commercial or vacant-land sales.
Title, planning, owners corporation and disclosure issues
The Section 32 must disclose title particulars, easements, covenants, planning zone and overlays, building permits in the last seven years, outgoings and — for apartments — owners corporation certificates and prescribed documents. Buyers should read the plan of subdivision against what they saw at inspection, and check for special levies, cladding rectification and other capital works in owners corporation minutes.
Building and pest inspections
A pre-auction building and pest inspection is normal, not optional. It is not part of the vendor's disclosure. Buyers should obtain their own inspections early enough to consider the report before deciding to bid and to walk away without financial loss if the report is unfavourable.
Finance and lender valuation
The buyer should have a firm understanding of their borrowing capacity, deposit position and the property's likely valuation before bidding. Most lenders require a formal valuation before releasing funds. A pre-approval is not a guarantee — it is an indicative offer subject to satisfactory valuation, verified income, unchanged circumstances and property type.
A shortfall between the contract price and the lender's valuation is a common cause of settlement failure at auction. Buyers should keep a realistic buffer, not stretch to the top of an indicative approval, and confirm the property type is acceptable to the lender (some lenders decline small apartments, serviced apartments, student housing or heritage-restricted properties).
Setting a bidding limit
Set a maximum before you arrive. Include duty, adjustments, legal fees, moving costs and a buffer for a valuation shortfall. Once at auction, emotion runs against buyers; a written limit is a disciplined defence.
Who can bid — and in what name
The name in which the property is bought has legal, duty and lending consequences. Individuals, joint owners, tenants in common with defined shares, companies, trusts and SMSFs each raise different issues. The purchaser name should be settled before the auction and used at bidding registration.
- Joint purchasers — joint tenants or tenants in common; the difference matters for estate planning and shares.
- Companies — director signing, ACN on the contract, GST and CGT treatment.
- Trusts — trustee name signs, trust deed in place, foreign-purchaser status of any beneficiary considered.
- SMSFs — bare-trust structure normally required for a borrowed acquisition; must be established before signing.
Changing the purchaser after the contract is signed can trigger sub-sale duty and other issues. Do it in advance.
Bidding through an authorised representative
A buyer who cannot attend may authorise another person to bid on their behalf, usually through a written authority to bid provided to the auctioneer before the auction. The authorised bidder should be someone who can be trusted to hold to the buyer's written limit and to sign the contract immediately on the fall of the hammer.
Identification and purchaser-name issues
The successful bidder will need to provide identification and the full purchaser name at the moment of signing. Ensure the exact legal name, spelling and structure match the intended title.
Auction rules and mandatory announcements
Auctions in Victoria are conducted under rules made by the Estate Agents Act 1980 (Vic) and enforced by Consumer Affairs Victoria. Before bidding starts, the auctioneer must make prescribed statements — including whether vendor bids will be made, whether co-owner bids are permitted, and that the auction is being conducted in accordance with the rules. Copies of the auction rules should be displayed at the auction.
Vendor bids and co-owner bids
A vendor bid is a bid made by or on behalf of the seller, permitted below the reserve price. The auctioneer must clearly announce each vendor bid — usually by calling out the words "vendor bid". Co-owner bids are permitted where one of several joint owners wishes to buy the others out; they must be pre-announced.
Dummy bidding is illegal
Dummy bidding — a bid made without disclosing that it is on behalf of the vendor, or a fictitious bid — is unlawful and attracts significant penalties. Buyers who suspect dummy bidding should raise it with Consumer Affairs Victoria.
The reserve price and "on the market"
The reserve is the minimum price the vendor is prepared to accept. Vendor bids can be used to progress the auction below the reserve. When bidding reaches or passes the reserve, the auctioneer will typically declare the property "on the market", meaning the property will sell to the highest bidder. Bids above the reserve are the ones that carry legal purchase risk for the bidder.
Late bids and disputed bids
The auctioneer has discretion to accept late bids before the hammer falls and to resolve disputed bids. Once the hammer falls, the sale is made to the person the auctioneer identifies as the highest bidder.
If the property is passed in
If bidding does not reach the reserve, the property is passed in. Under Victorian auction rules, the highest bidder at the time of passing in is normally given the first opportunity to negotiate with the vendor. A sale negotiated immediately after a publicly advertised auction is still treated as an auction sale, and no cooling-off period applies.
A buyer negotiating post-auction should apply the same discipline as during bidding — signing the contract remains unconditional.
When the transaction becomes legally binding
On the fall of the hammer, the successful bidder becomes bound to sign the contract of sale on the terms disclosed before the auction. Both parties must sign — the buyer and a person authorised to sign for the vendor — immediately after the hammer, and the contract is then dated. The deposit is paid at signing.
Auction contracts are unconditional
Buyers cannot add a finance, inspection or due-diligence clause after winning at auction. Special conditions that were in the contract before the auction remain part of the contract; the buyer cannot introduce new ones.
No cooling-off period
Section 31 of the Sale of Land Act excludes cooling-off for sales at, or within three clear business days before or after, a publicly advertised auction. If a private-sale contract is signed inside this window, cooling-off will not apply.
The deposit
The standard deposit at auction is ten per cent of the purchase price, usually paid by bank cheque, direct deposit or approved electronic transfer at signing. Some vendors will agree to a smaller pre-auction deposit (for example five per cent) in exchange for a written commitment to pay the balance shortly after. Any reduction should be agreed before the auction and endorsed on the contract.
Settlement periods, inclusions and exclusions
The settlement period is set by the contract — commonly 30, 60 or 90 days. Inclusions (dishwasher, blinds, air-conditioners, sheds) and exclusions must be listed accurately in the contract before the auction, not verbally agreed afterwards.
Foreign purchasers
Foreign persons should obtain foreign-investment approval or verify a developer's exemption certificate covers the intended purchase before bidding. From 1 April 2025 to 30 June 2029 foreign persons are generally prohibited from purchasing established dwellings, subject to limited exceptions. Foreign-purchaser additional duty and land tax surcharges may also apply.
What happens if the successful bidder cannot settle
If the buyer cannot complete the purchase, the vendor may serve a default notice, terminate the contract, forfeit the deposit and — if the property is later resold for less — recover the shortfall from the defaulting buyer as damages, together with resale costs and interest. Termination and damages proceedings are common enough to be a real risk, not a theoretical one.

Frequently asked questions.
- Is there a cooling-off period after buying at auction in Victoria?
- No. Cooling-off does not apply to a sale at a publicly advertised auction, or to a private-sale contract signed within three clear business days before or after such an auction.
- Can I add a finance clause to an auction contract?
- Only if the special condition is in the contract before the auction. Once you win, the contract is fixed — you cannot introduce new conditions.
- What deposit is payable at auction?
- Ordinarily 10 per cent of the purchase price on the fall of the hammer. A smaller deposit is sometimes negotiated before the auction and endorsed on the contract.
- What is a vendor bid?
- A vendor bid is a bid by or on behalf of the seller, made below the reserve to progress the auction. The auctioneer must clearly announce each vendor bid.
- What does 'on the market' mean?
- It means the reserve has been reached and the property will sell to the highest bidder. Bidding above this point carries genuine purchase risk.
- What happens if the property is passed in?
- If the reserve is not reached, the property is passed in. The highest bidder is normally given the first opportunity to negotiate. A resulting sale is still treated as an auction sale, with no cooling-off.
- Can I bid without attending?
- Yes — an authorised representative can bid for you under a written authority to bid provided to the auctioneer before the auction.
- Do I need to arrange finance before bidding?
- Yes. You should have a firm pre-approval, a realistic view of valuation risk, and a buffer for a shortfall. Winning without finance is a serious default risk.
- What if my finance falls through after auction?
- You are still bound. The vendor may terminate, forfeit the deposit and recover any resale shortfall as damages. Obtain legal advice immediately.
- Do foreign buyers need FIRB approval before bidding?
- Yes. Approval or a valid exemption certificate covering the intended purchase should be in place before bidding, because the auction contract will be unconditional.
- Is dummy bidding legal?
- No. Dummy bidding is unlawful in Victoria and attracts significant penalties. Report suspected dummy bidding to Consumer Affairs Victoria.
- Should I have a lawyer review the auction contract?
- Yes. A pre-auction review of the Section 32 and contract is the single most cost-effective legal step a buyer can take.
