Buying at auction in Victoria is fundamentally different from buying via private sale. The rules change, the protections shrink, and the financial commitment is immediate. If you're not prepared, you can make a very expensive mistake.
This guide covers everything you need to know — and do — before bidding at a Victorian property auction.
How Victorian auctions work
A property auction is a public sale where the property is sold to the highest bidder. The auctioneer opens proceedings, bidding takes place, and if the reserve price is met, the property is sold “under the hammer.” The highest bidder becomes the purchaser immediately — there is no further negotiation, no conditions, and no going back.
The auction is governed by the Sale of Land Act 1962 (Vic) and the Estate Agents (Contracts) Regulations, which set rules around conduct, vendor bidding, and disclosure obligations.
No cooling-off period
This is the single most important difference between auction and private sale. When you buy at auction, there is no cooling-off period. Once the hammer falls and you sign the contract, you are legally bound to complete the purchase.
This also applies if you buy within 3 business days beforea scheduled auction — the law treats pre-auction purchases the same way. For more on how cooling-off works in private sales, see our cooling-off period guide.
No subject-to-finance
At auction, the contract is unconditional. There is no subject-to-finance clause, no building inspection clause, and no get-out provisions. You are committing to buy the property as-is, at the price you bid, with no conditions attached.
This means you must have your finance pre-approved and confirmed before auction day. If you win at auction and your loan falls through, you will forfeit your deposit (typically 10% of the purchase price) and potentially face legal action from the vendor for breach of contract.
Review the Section 32 before auction day
Because there's no cooling-off period and the contract is unconditional, all your due diligence must happen before the auction. This includes:
- Reading and understanding the Section 32 Vendor's Statement
- Reviewing the Contract of Sale and all special conditions
- Completing a building and pest inspection
- Having your solicitor review and approve the documents
- Confirming your finance is unconditionally approved to your maximum bid amount
A Pre Contract Review is particularly valuable before an auction because it highlights issues you might otherwise miss — and gives you time to investigate them before auction day, when it's too late to back out.
Setting your maximum bid
Before the auction, decide on your absolute maximum price — and commit to it. Factor in:
- Your pre-approved loan amount
- All buying costs — stamp duty, legal fees, and inspections (see our stamp duty guide and hidden costs guide)
- Any renovation or repair costs identified during your pre-auction inspections
- A financial buffer for unexpected expenses after purchase
Auction environments are designed to create excitement and urgency. The number you set calmly at home, with all the facts in front of you, is a better number than the one you come up with in the heat of competitive bidding.
What happens when you win
If you're the highest bidder above the reserve price, the property is sold to you on the spot. You will:
- Sign the contract immediately— right there at the auction venue. The contract is unconditional.
- Pay the deposit— typically 10% of the purchase price, paid on the day. Bring a bank cheque or confirm with the agent in advance what payment methods they accept. Personal cheques are rarely accepted.
- Settlement follows— the standard settlement period applies (usually 30–90 days, as stated in the contract).
Passed-in properties
If bidding doesn't reach the vendor's reserve price, the property is “passed in.” In this scenario:
- The highest bidder gets first right of negotiation — you go inside with the agent and negotiate directly with the vendor on price and conditions.
- If you reach an agreement, you sign the contract. Note there is still no cooling-off period, as the sale is within 3 business days of the scheduled auction.
- If no agreement is reached, the property may go to private sale. At that point, the cooling-off period is restored for any new buyers.
Vendor bidding rules
In Victoria, vendors are allowed to make bids at their own auction — but there are strict rules governing this practice:
- The auctioneer must declare vendor bids clearly and audibly
- Only one vendor bid is permitted per auction
- The vendor bid must be below the reserve price
- A vendor bid cannot be the final (winning) bid — a genuine bidder must exceed it
Vendor bids are used to move the bidding along when genuine bids stall. If you notice a bid that seems to come from nowhere with no visible bidder, it may be a vendor bid — listen carefully for the auctioneer's declaration.
Auction day checklist
Before you attend the auction, make sure you have completed every item:
- Reviewed the Section 32 and Contract of Sale in full
- Had your solicitor review the documents and provide clearance to bid
- Obtained unconditional finance pre-approval for your maximum bid amount
- Completed building and pest inspections
- Checked the Owner's Corporation certificate (if buying an apartment or townhouse)
- Set your absolute maximum bid and committed to not exceeding it
- Arranged the deposit payment (bank cheque or confirmed alternative method)
- Brought valid photo identification
- Registered to bid with the agent before the auction begins
Be prepared, not pressured
Auctions favour prepared buyers. The vendors and agents have done their homework — make sure you've done yours. Start with a Pre Contract Review to flag any issues in the Section 32 and contract, then bring those findings to your solicitor. It's the fastest way to go into auction day with confidence rather than uncertainty.
