It’s a Saturday morning in Terrigal. A crowd is standing on a front lawn, the auctioneer is calling for an opening bid, and you have a few seconds to decide whether to raise your hand. Most people who ask us how to bid at auction aren’t worried about the mechanics. They’re worried about that moment: getting carried away, paying too much, or freezing and watching someone else walk off with the house.
The good news is that almost everything that decides an auction happens before the auctioneer opens their mouth. Here’s how we prepare buyers for auction day, and what we watch for once bidding starts.
The auction is won or lost in the week before
An auction sale in NSW is unconditional. When the hammer falls and you’re the highest bidder above the reserve, you sign the contract and pay the deposit on the spot. There’s no cooling-off period for a property bought at auction, and you can’t make the sale subject to finance or a building report afterwards.
That changes the order you do things in. With a private treaty sale you can make an offer and sort out the details later. At auction, the details have to be sorted first. Before we let a client bid, we want four things done.
- Finance confirmed. Not just a pre-approval sitting in your inbox, but a conversation with your lender about this specific property and whether they’ll value it at your price.
- The contract reviewed by your solicitor or conveyancer, including the deposit amount and settlement terms. Ask the selling agent early whether they’ll accept a smaller deposit, because that has to be agreed before the auction, not after.
- Building and pest inspections completed. You’re paying for these on a property you may not win, which stings, but buying without them is a bigger risk.
- Deposit funds ready in a form the agent will accept on the day.
If any of those isn’t done, you’re not ready to bid. It really is that simple.
Your limit is a number, not a feeling
Every buyer walks in with a budget. Far fewer walk in with a limit, and the difference matters.
A budget is what you’d like to pay. A limit is the figure where you stop, even if the other bidder is one increment away from giving up. We ask clients to set it using recent sales of genuinely comparable homes nearby, what the property is worth to them specifically, and what their lender will actually lend. Then we write it down.
The price guide is useful, but don’t anchor on it. NSW agents can’t legally quote below what they genuinely expect a property to sell for, yet a guide is still an estimate. Your own research on comparable sales is what should set your number. On the Central Coast that research needs to be hyper local. A home a street back from the water in Avoca Beach and one on a busy road in the same suburb can sell for very different money, and a suburb average hides all of it.
How the bidding actually runs
You’ll need to register as a bidder with the selling agent before the auction starts. Bring photo ID. You’ll get a bidder number, and you can’t bid legally without one.
The auctioneer reads out the conditions of sale, then asks for an opening bid. From there they’ll suggest increments, and bids usually get smaller as the price climbs. You don’t have to accept the increment they call. You can offer a smaller amount, and the auctioneer can accept or refuse it.
You may hear the auctioneer announce a “vendor bid”. This is a bid made on behalf of the seller, and in NSW the auctioneer has to say clearly when a bid is a vendor bid. It’s there to move a slow auction towards the reserve. It isn’t a real buyer, so don’t read it as competition.
At some point the auctioneer will say the property is “on the market”. That means bidding has passed the reserve and the home will sell to the highest bidder. The mood shifts at this point, and it’s where most overspending happens.
Tactics that help, and some that are just folklore
There’s a lot of auction advice floating around. Some of it works. Some of it is more about looking confident than being effective.
Bid clearly and quickly. Hesitation tells the room you’re close to your limit. A firm, immediate bid in a clear voice suggests you have room to keep going, even if you don’t.
Know where to stand. We like a spot where we can see the auctioneer and the other bidders. Watching body language tells you a lot. A couple conferring before every bid is usually near the end of their budget.
Don’t open unless it helps you. Opening the bidding can set the tone, but it also gives away that you’re keen. We decide this case by case.
Knockout bids are overrated. A big jump can rattle other buyers, and it can also just hand the seller money you didn’t need to spend. If you use one, use it once and with a reason.
Emotion is the real opponent, and it’s why many buyers choose to have someone else bid for them. A professional bidder doesn’t fall in love with the kitchen. If you’d rather not be the one on the lawn, our auction bidding service puts one of our team in that spot, working to the limit you’ve set together.
Pre-auction offers: sometimes the smarter move
You don’t always have to wait for auction day. Many sellers will consider an offer beforehand, especially if it’s strong and clean. Signing before the auction takes your competition out of the picture entirely.
There’s a catch. The agent will usually ask you to waive the cooling-off period so the deal is as firm as an auction sale. That means your finance and inspections need to be finished before you sign, exactly as they would for the auction.
A pre-auction offer tends to make sense when the property has had modest interest, when you’d genuinely pay a premium to stop other buyers getting a shot, or when you know you’d struggle in a crowded auction. It works less well when an agent is using your offer to push other buyers. Some homes on the Coast never reach an auction at all; if you’d like to see more of those, our guide to finding off-market homes on the Central Coast covers how that side of the market works.
If it passes in, the real negotiation starts
When the highest bid doesn’t reach the reserve, the property is “passed in”. Being the highest bidder at that point usually gives you the first chance to negotiate with the seller, although that’s convention rather than a rule.
This is a good position to be in. Nobody else is bidding against you, and the seller has just watched the market tell them what it thinks. The agent will often share the reserve or a figure the seller would accept. You don’t have to meet it.
One point that catches people out: in NSW, a contract signed on the day of the auction, even after it passes in, generally has no cooling-off period either. Treat a post-auction deal with the same care as a hammer sale.
Getting help without paying for more than you need
Some buyers want someone for the whole search. Others have found the house themselves and just want a steady hand for the bidding. Both are reasonable. Our team works on flat fees, so you know the cost up front, and if you’re weighing that up our breakdown of what a buyers agent costs on the Central Coast sets out how the fees compare.

Common questions about bidding at auction
How do you put in an offer on a house in NSW that’s going to auction?
Tell the selling agent in writing that you’d like to make a pre-auction offer, and state your price and any terms. Expect to be asked to exchange contracts with the cooling-off period waived, so have your finance, inspections and legal review done first. The seller can accept, counter or decide to go ahead with the auction.
What happens if the property is passed in?
If bidding stops below the reserve, the property is passed in and the highest bidder normally gets the first chance to negotiate privately with the seller. It isn’t a legal right, but most agents follow it. Any contract signed that day usually carries no cooling-off period.
What is the typical settlement period for an auction in NSW?
The settlement period is written into the contract, and the seller sets it before the auction. Check it with your conveyancer when you review the contract. If you need a longer or shorter settlement, ask the agent before auction day, because you can’t change the terms once the hammer falls.
Can someone else bid at auction on my behalf?
Yes. A buyers agent, friend or family member can bid for you, as long as they register as a bidder and hold written authority from you. Many buyers prefer it because it keeps emotion out of the bidding.
What are common mistakes buyers make at auction?
The big ones are bidding without finance or inspections sorted, having a budget but no hard limit, and reacting to vendor bids as if they were real buyers. Another is forgetting that there’s no cooling-off period, so there’s no way back if you overreach.
Do I have to bid in the increments the auctioneer calls?
No. You can offer a smaller increase than the one called. The auctioneer can accept or refuse it, but smaller bids are common late in an auction when the price is close to where most buyers stop.
