Using a buyer's agent at auction

Australian auctions are built to compress a decision that ought to take a fortnight into a few minutes of public theatre. The selling agent wants paddles in the air. The vendor wants a price the campaign photographs were styled to justify. You want a house you can live in at a number you can explain to a lender. Those three aims do not sit in the same sentence, which is why a buyer's agent — a licensed professional paid by you, not by the seller — still earns a living in rooms that look, from the footpath, like a Saturday hobby.

The legal colour around auctions is simpler than the marketing. Once the hammer falls, you have generally bought the property. There is typically no cooling-off period after an Australian auction. That single fact should shape the whole week before the event, not the five minutes of bidding. If you only remember one sentence from this guide, remember that one, then go and read our separate piece on cooling-off periods, private treaty and auction. The rules are state-based and they change. This is not a substitute for advice from your solicitor or conveyancer.

This article is about the practical job: what a buyer's agent actually does at auction, what they cannot do, and how to brief one so the paddle is a tool rather than a mood. It sits in our buying process hub. If you are still deciding whether to hire anyone at all, start with what a buyer's agent does and when you do not need one.

Why the room is a poor place to think

Auction technique is sold as nerve and theatre. The work that matters is duller. A useful agent will have walked the property more than once, read the contract with your conveyancer, booked building and pest inspections, priced the house against recent comparable sales rather than the suburb median, and written down a limit you can live with if you win and a plan you can live with if you lose.

That last point is underrated. Plenty of buyers hire an agent because they freeze on the phone. Plenty of others hire one because they do the opposite: they keep bidding to stay in a story. A written limit, agreed the day before, is the only reliable antidote to both. In New South Wales, a buyer's agent must not exceed the agreed purchase price without your express written authority. Other states have their own agency rules. Ask how the limit will be recorded, who can vary it, and whether a mid-auction call counts as a variation. If the answer is vague, the authority is not finished. See the buyer's agency authority before you sign.

The agent is not there to "win". Winning a bad house at a full price is a very expensive hobby. They are there to buy this house at a defensible number, or to put the paddle down and go to lunch. If that second outcome makes the firm look less impressive on Instagram, you have hired the wrong firm.

The week before is the actual campaign

Treat the auction date as a deadline for due diligence, not as the start of it. Because cooling-off will almost certainly not be available, the inspections that a private-treaty buyer sometimes squeezes into the days after exchange have to happen before you raise a hand. Building and pest reports are the buyer's choice in every state. They are also strongly advisable. An agent who pressures you to skip them because "everyone knows this street" is showing you a red flag, not a shortcut.

Finance belongs in the same week. Lenders do not care that the room was exciting. If your approval is still a conversation, you are not ready to be bound. A careful agent will ask to see the approval, or at least a written pre-approval that matches the limit, and will tell you if the numbers only work if every other cost in the file magically disappears. Stamp duty, the agent's own fee, inspections, and the work your conveyancer will do after the hammer are all part of the ceiling. A limit that ignores them is not a limit. It is a wish.

The contract of sale should already be with your solicitor or conveyancer. Special conditions, inclusions, settlement dates, and any vendor-supplied reports need reading while you can still walk away for free. The buyer's agent can flag issues and chase answers from the selling agent. They cannot replace the lawyer. Do not let the two roles blur because Saturday is coming.

Comparable sales are the unglamorous core of the price. A terrace in Middle Park is not worth "about the same as the one three streets over" if that sale included a parking stacker, a renovated rear, or a vendor who had already bought elsewhere. The agent should show you the sales they are using, not a vibe. If they cannot explain why this house is worth the limit in a sentence you could repeat to a friend, the limit is not ready.

On the day

A professional buyer's agent arrives with the file, not with a pep talk. They will have registered, checked the vendor bid rules with the auctioneer, and confirmed the order of business. Vendor bids are lawful in many campaigns if they are announced. Dummy bidding is not. Your agent should know the difference and should not be impressed by a paddle that materialises from the selling office.

They will usually bid. Some buyers prefer to stand beside them. Some prefer not to be in the room at all. Both are legitimate, provided the authority is clear about who speaks. What is not legitimate is a running commentary designed to lift your limit in public. If you want to raise the ceiling, do it in writing, in private, with a number attached to a reason — a second comparable, a missed inclusion, a settlement date you now like. "I just really want it" is not a reason. It is how auction campaigns are designed to work.

Passed-in properties are a different conversation. If the reserve is not met, the highest bidder often gets the first chance to negotiate. That negotiation is closer to private treaty than to the auction that just failed, but the cooling-off picture can still be unfriendly, especially if you were a registered bidder and you buy on the same day. Do not assume a passed-in house has magically acquired a cooling-off period. Ask your conveyancer before you sign anything on the bonnet of a car. Our cooling-off guide sets out the high-level pattern; the contract in your hand is the one that counts.

What they do after the hammer

If you win, the work is not over. You will usually sign immediately. A deposit is due on the terms in the contract. The file then moves into settlement: coordinating the people you hired, booking a final inspection, and making sure the inspector's list, the conveyancer's requisitions and the lender's conditions are talking to each other. A buyer's agent who disappears at the handshake has sold you a Saturday, not a service.

If you lose, a good agent will debrief without theatre. Was the limit wrong, or was the house? Is there another property already on the shortlist, including off-market stock that will not wait for your disappointment? The point of paying someone is that the campaign continues on Monday. The point is not a post-mortem that makes you feel you should have bid another fifty thousand dollars for sport.

How to brief an auction specialist without wasting a retainer

Write the brief before the first meeting. Suburbs you will actually live in. A property type. Deal-breakers. A budget that includes costs. A timeline that assumes you may lose the first two auctions. Then ask the questions on our interview list. Are they licensed in the state where the property sits? Do they act only for buyers on this deal, or might they also take a vendor commission from the same campaign? Exclusive buyer agents should not take vendor commission on the same deal. Membership of a body such as REBAA is a professional signal, not a licence and not a regulator.

Be precise about the product. A full search that happens to end at an auction is one fee. An auction-only engagement, where you have already found the house, is another. The fees hub is the place to compare those models. The clause to watch is the success fee if you later buy a property the agent never showed you, or if you bid yourself after they have priced the file. Unclear success fees are a classic way a useful Saturday becomes a disputed invoice.

When an auction agent is worth the fee — and when they are not

The role earns its keep when you cannot be in the city, when you freeze or overbid in public, when the contract is denser than your Saturday, or when you need someone who will tell you the house is fully priced before you fall in love with the kitchen. It is less useful when you have already done the inspections, you have a sharp conveyancer, the campaign is quiet, and you can hold a number. In that case, bidding yourself — or paying a tightly scoped auction-only fee — may be the adult decision.

Either way, do not let the absence of cooling-off become a personality test. It is a legal feature of the method of sale. Prepare as if you will be bound, because you generally will be. Hire the person who treats that fact as the brief, not as a thrill.

The short version

At auction you are usually bound when the hammer falls. Building and pest inspections, finance and a contract review belong in the week before. A licensed buyer's agent prices the house, holds a written limit, bids or stands down, and stays on the file through settlement. They must not also be paid by the vendor on the same deal. They cannot replace your inspector or your lawyer. If the room is the only place you plan to think, you are already late.
