Auction Rules Victoria: What First Home Buyers Must Know Before Bidding

Melbourne is one of the most auction-intensive property markets in the world. For first home buyers, auctions are not just a different way to buy a property — they are a fundamentally different legal event, with different rules, different finality, and different risks than a private sale. Getting these rules wrong, even once, can be catastrophically expensive.

The Defining Feature: No Cooling-Off Period

In Victoria, a standard private sale gives buyers a three-business-day cooling-off period. If you sign a contract and change your mind, you can withdraw (losing a penalty of $100 or 0.2% of the purchase price — whichever is greater), but the purchase does not proceed.

Auction contracts have no cooling-off period, at all.

Under the Sale of Land Act 1962, a property purchased at a publicly advertised auction is an unconditional sale from the moment the hammer falls. You cannot withdraw because you could not get finance. You cannot withdraw because a subsequent building inspection revealed serious structural defects. You cannot withdraw because you had a night's sleep and reconsidered. Once the contract is signed on auction day, you are legally obligated to settle.

The three-business-day cooling-off prohibition also extends to contracts signed within three clear business days before or after a scheduled auction. A private sale signed on the Thursday before a Saturday auction, or the Monday after one, is also unconditional — no cooling-off.

This has a specific practical consequence: all due diligence must be completed before you bid. The checklist includes unconditional finance pre-approval confirmed, conveyancer review of the Section 32 and contract completed, and building inspection done. Only once all three are settled is it safe to register to bid.

The 10% Deposit Requirement

If the hammer falls in your favour, you are required to sign the contract immediately and pay the deposit on the day. The standard deposit in Victoria is 10% of the purchase price, paid by bank cheque or electronic transfer. In some cases, you may be able to negotiate a 5% deposit before the auction — but this requires the vendor's agreement in writing before auction day.

You need to have this money available in liquid form — not as part of your home loan drawdown, not tied up in a term deposit you cannot access until next week. The deposit is paid directly to the selling agent and held in their trust account until settlement.

Vendor Bids: What They Are and Why They Matter

Victorian auction law permits the auctioneer to place bids on behalf of the vendor — these are called vendor bids. They are legal, regulated, and explicitly disclosed.

The rules:

• The auctioneer must announce at the start of the auction that they are authorised to make vendor bids
• Every vendor bid must be explicitly declared as a "vendor bid" at the time it is made
• Vendor bids can only be placed below the reserve price
• Once the reserve is met, the auctioneer cannot place further vendor bids

The purpose of vendor bids is to simulate competition when genuine bidding is slow, or to signal the vendor's price expectations when buyers are anchored below the reserve. A series of vendor bids without genuine bidder response tells you the room is well below the reserve. A vendor bid that prompts genuine bidder responses tells you buyers are engaged.

Recognising vendor bids gives you information: if the auctioneer has bid three times and nobody else has moved, you know where the market genuinely is relative to the vendor's expectations.

"On the Market" — What This Declaration Means

During an auction, the auctioneer may pause and announce they are seeking instructions from the vendor. They disappear inside (metaphorically or literally) and return after a brief consultation.

When the auctioneer returns and declares the property is "on the market," it means the reserve price has been met and the property will sell to the highest bidder. From this moment, the sale is certain — the vendor has irrevocably committed to sell at whatever price the bidding reaches. There is no more negotiation, no reserve adjustment, and no ability for the vendor to withdraw.

If you are in the bidding when "on the market" is declared, you are competing for a property that is definitively selling. This is the moment when bidding fever — the psychological drive to "beat" the other bidder rather than adhere to your own price limit — most frequently results in overbidding.

"Passed In" and the Right of First Negotiation

If the bidding does not reach the vendor's reserve and the vendor refuses to lower their expectations, the property is "passed in." Under Victorian auction law, the highest bidder at the time of passing in is granted the exclusive first right to negotiate with the vendor privately.

This is an important strategic point. If you suspect a property may be passed in — because the bidding stalled well below what you estimate the vendor wants — you should ensure you hold the highest bid at the point of passing in, even if that bid is below your true limit. The first right of negotiation means no other buyer can approach the vendor until you have had your negotiation. You are not locked into the passed-in bid; it is simply the opening position for a private negotiation that follows.

Registering to Bid

Victoria requires all bidders to register before bidding. You need to provide proof of identity (driver's licence or passport) to the agent before the auction begins, and you will receive a bidder's number. You cannot bid without registering.

Registration does not commit you to buy. It simply identifies you as a bidder. You can register and choose not to bid if you arrive and something feels wrong.

Bidding Psychology: What to Watch For

Melbourne auctioneers are professionals. The best ones move quickly, create momentum, and use specific techniques to induce bidding:

Low opening bids. Auctioneers frequently start the auction well below the reserve to get buyers psychologically engaged. Once you have made a bid, you are psychologically invested.

Fast increments. Auctioneers call for large bid increments ($10,000 or $25,000) to create momentum and discourage small bids that slow the pace. You are entitled to bid any amount you choose. Bidding an unusual odd number (like $12,500 rather than $10,000) can disrupt rhythm and signal a deliberate strategic buyer rather than an emotionally reactive one.

Anchoring. The numbers called — whether vendor bids or genuine bids — set an anchor for participants. If the first bid is $650,000 and your independent research suggested $600,000 was fair value, you are now psychologically pulled toward $650,000 as a reference point, not $600,000.

The counter-strategy is simple to describe and difficult to execute: determine your maximum price before the auction, in writing, based on your own comparable sales research, your budget, and the specific attributes of the property — not the auction atmosphere. Do not exceed it.

The Statement of Information

Before the auction, the selling agent must provide a Statement of Information (Section 47AF of the Estate Agents Act 1980). This document contains three components: a comparable sales analysis, a median price for the suburb, and an indicative price range for the property being sold.

Agents are legally required to set the indicative price range based on genuinely comparable sales. Advertising below the indicative range constitutes underquoting, which is monitored by Consumer Affairs Victoria. However, the Statement of Information is a useful starting point for your own research — compare the agent's comparable sales selection with your own research to assess whether the price range is realistic.
