An Auction Day Checklist for Buyers
Published 15 August 2025
What to prepare before you register to bid, how to approach the auction itself, and what happens legally the moment the hammer falls.
Buying at auction is unlike any other property purchase in Australia, because there is no cooling-off period and a winning bid creates an immediately binding contract. Everything that would normally happen after exchange, from finance approval to contract review, needs to happen before you register to bid. This checklist works through what to organise in the lead-up to auction day and what to do once the auction itself begins.
Get the Contract Reviewed Before Auction Day
Request the contract of sale and any vendor disclosure documents (a Section 32 statement in Victoria, or the equivalent in other states) as early as possible, and have your conveyancer review them well before the auction date. Because there is no cooling-off period to fall back on, this review needs to happen properly, checking for special conditions, easements, encumbrances and anything unusual about the title, before you commit to bidding at all. If your conveyancer flags a concern, you still have time to ask questions or negotiate changes before the auction, which is not possible once the hammer falls.
- Have your conveyancer review the contract and any vendor disclosure statement in advance.
- Confirm your finance is unconditional or that you have sufficient cash to complete without it.
- Arrange building and pest inspections before auction day, not after.
- Bring photo identification and the required deposit method to register as a bidder.
Arrange Unconditional Finance in Advance
Because a successful bid is binding immediately, your finance needs to be unconditional, or you need to be confident you can settle in cash or through an already-approved facility, before you register. A pre-approval that is still subject to valuation or further conditions is not the same as unconditional approval, and this distinction matters far more at auction than in a private treaty sale. Speak with your lender or broker about exactly what "unconditional" means for your specific loan, since terminology can vary between lenders. The MoneySmart guide to buying a house outlines general steps for getting finance in order before you commit to a purchase.
Complete Inspections and Searches Beforehand
Arrange a building and pest inspection, and any other checks you would normally do during a cooling-off period, in the days before the auction rather than after. If several buyers are considering the same property, ask the agent whether a group building inspection has already been arranged, since this can save the cost of a separate inspection while still giving you the same information. Your conveyancer can also run preliminary title and planning searches ahead of auction day so any red flags are identified while you can still walk away without consequence.
Set Your Limit and Register to Bid
Decide your maximum bid in advance, in writing if it helps, and treat it as a firm limit rather than a starting point for negotiation with yourself on the day. Auctions are designed to create competitive pressure, and having a number decided beforehand, with your finance and inspections already sorted, is the best protection against bidding beyond what you can genuinely afford. Bring photo identification to register as a bidder, along with whatever deposit method the agent has specified, since registration requirements vary between agencies and states.
Understand What Happens the Moment You Win
As soon as the auctioneer's hammer falls on your bid, a binding contract exists, and you will typically be asked to sign the contract and pay the deposit immediately, on the spot. There is no cooling-off period to change your mind afterward in most states when a property sells at auction. Some states allow the vendor and buyer to agree a short period to arrange finance if it fell through unexpectedly, but this is not guaranteed and should never be assumed going in.
What to Do If the Property Passes In
If bidding does not reach the vendor's reserve price, the property is passed in, and the highest bidder is often given the first opportunity to negotiate privately with the vendor immediately afterward. This negotiation can move quickly, so having your conveyancer reachable by phone on auction day, even if they are not physically present, means you can get a fast answer on any contract question before agreeing to terms.
Attend a Few Auctions Before You Bid
If you have not bought at auction before, attend several auctions in your target area as an observer before you plan to bid seriously. This helps you get comfortable with the pace, the way auctioneers manage bidding increments, and how competitive a particular market segment is, all of which is harder to judge from the outside than it looks. It also gives you a realistic sense of how prices compare with agent guides, since quoted price ranges are not always a reliable predictor of where bidding will actually finish.
Consider bringing a friend, family member or buyer's agent along on the day, both for a second opinion during any last-minute negotiation and simply to help you stay level-headed once bidding starts. Auctions are designed to create urgency, and having someone beside you who is not emotionally invested in winning that specific property can be a useful check on your own decision-making in the moment.
Line Up Your Conveyancer Before You Bid
Because everything at auction happens on a compressed timeline with no cooling-off safety net, the single most useful thing you can do is engage a conveyancer before you start attending auctions seriously, not after you have already won one. Getting a fixed-fee quote and having your conveyancer on standby for contract review means you can move confidently when the right property comes up, whether it is a standard residential purchase or your first time buying at auction.
