Auction day: what actually happens, step by step

Auctions are theatre, and if you're at your first few the choreography can feel like everyone knows the rules but you. This is part of our buying process guide, and you can run the preparation with our auction day checklist. Here's what actually happens, in order.

Before you go

If you plan to bid, you should already have pre-approval, your building and pest results (auction sales are unconditional, so inspect in advance), your conveyancer's review of the Section 32 and contract, a written maximum you won't exceed, your deposit ready (10% on the day), and your bidder registration done. In Victoria you must register to bid, with photo ID, so do it early because the queue is slow.

Arriving and the pre-auction phase

Auctions usually run at the property. Arrive 20 to 30 minutes early to walk through one last time, hand over your registration, read the crowd, and position yourself where the auctioneer can see you. Bring an umbrella, hat, and water, since they run rain or shine. In the 15 minutes before kick-off the agent works the crowd, gauging interest. A crowd of 50 doesn't mean 50 bidders, most are onlookers; watch for people inspecting carefully or carrying themselves like buyer's agents.

The opening and bidding

At the scheduled time the auctioneer gives their spiel (sales talk, ignore it), makes the required legal disclosure that the Section 32 is available, and invites an opening bid. The reserve, the vendor's secret minimum, is not disclosed. The first bid often takes a while: a bidder may open $50,000 to $100,000 below the expected price, or the auctioneer makes a vendor bid (which in Victoria must be announced) to get things moving.

Bids are made with a hand, eye contact, or a paddle, and the auctioneer sets the increments, often $25,000 to $50,000 early, shrinking to $5,000 or $10,000 near the reserve, then $1,000 to $2,000 at the end. You can bid the called increment or call your own number; a big jump ("$1,030,000") can intimidate other bidders. At some point the auctioneer signals whether the property is on the market (above reserve, it will sell) or still in conference (below reserve, often followed by a quiet word with the vendor). Once it's on the market, the next highest bid wins.

Going once, and what comes after

When bidding slows, the auctioneer calls "going once, going twice," pauses, and either brings the hammer down ("Sold!") or, if the reserve wasn't met, declares it passed in to the highest bidder, who gets first right to negotiate with the vendor immediately, where the reserve is often revealed. Passed in, you can accept the reserve, counter, or walk (losing the first-right advantage).

If you win, you sign the contract on the spot and pay the deposit; the cooling-off period does not apply to auctions, so you're committed, and your conveyancer takes over settlement. Bring photo ID, your registration, deposit means, your conveyancer's number, a notebook, and a steady friend.

What people get wrong

The common first-timer mistakes: bidding too early or too eagerly (it pushes the price up, so many experienced bidders wait); dragging the auction up in tiny increments rather than a confident jump that unsettles others; not registering early; and forgetting the property might pass in, so plan for both. The biggest one is going over your limit. Auctions are engineered social pressure, the eye contact, the pace, the build to "going once", all designed to extract one more bid. Write your maximum down and hold it. There will be other properties; the one you bid up $50,000 in the moment is the one you pay for over 25 years.
