Why Registration Matters

Before you can place a single bid at an Australian property auction, you must be registered. This is a legal requirement under state and territory auction regulations. Without registration, the auctioneer will not accept your bids, no matter how enthusiastic you are.

Registration serves several purposes: it confirms your identity, ensures you have the legal capacity to enter a binding contract, and creates a record of all participants. It also gives the selling agent a way to contact you after the auction if needed.

If you are new to the auction process, it helps to first understand how to bid at auction before diving into the registration details.

What Documents Do You Need?

Photo Identification

You will need at least one form of government-issued photo ID. Acceptable documents include:

Australian driver's licence — the most commonly used form of ID at auctions
Australian passport — valid and not expired
Foreign passport — if you are an overseas buyer, bring your passport plus any FIRB (Foreign Investment Review Board) approval documentation
Proof of age card — issued by your state or territory

Some agencies may request two forms of ID, so bringing a backup is always a good idea.

Solicitor or Conveyancer Details

You will need to provide the name, firm, phone number, and email address of your solicitor or conveyancer. This person handles the legal side of the property transfer if you win the auction. You should have a solicitor or conveyancer engaged before auction day — not after.

Your legal representative should have already reviewed the contract of sale, Section 32 (in Victoria), or equivalent vendor disclosure documents. If they have flagged any issues, you need to know about them before you register.

Proof of Funds or Finance Pre-Approval

While not always a strict requirement for registration, most agents will ask about your financial position. Having your finance pre-approval letter on hand demonstrates you are a serious buyer and can settle the purchase.

If you are paying cash, you may be asked to show evidence of funds such as a bank statement.

Deposit Payment Method

The winning bidder must pay a deposit immediately after the auction — typically 10% of the purchase price. You should come prepared with:

A bank cheque made out to the real estate trust account (ask the agent for the exact payee details in advance)
A personal cheque — accepted at some auctions, though bank cheques are preferred
Electronic transfer details — increasingly common, especially for online auctions

Check with the selling agent beforehand to confirm which payment methods they accept.

Step-by-Step Registration Process

Step 1: Arrive Early

Plan to arrive at least 20-30 minutes before the scheduled auction time. Registration can take a few minutes, and there may be a queue if multiple bidders are registering. Arriving early also gives you time to settle in and observe the environment.

Step 2: Find the Registration Desk

The selling agent will have a registration table or desk set up near the auction location. At on-site auctions, this is usually at the front of the property. For auction rooms, look for signage or ask the staff.

Step 3: Complete the Registration Form

You will fill out a bidder registration form that typically asks for:

Full legal name
Current residential address
Contact phone number and email
Solicitor or conveyancer details
Whether you are bidding on behalf of someone else (if applicable)
Acknowledgement that you understand the auction conditions

Step 4: Present Your ID

Hand over your photo ID for verification. The agent will check it against the details on your registration form and may take a photocopy or note the ID number.

Step 5: Receive Your Bidder Number

Once registered, you will be issued a bidder number — usually printed on a card or paddle. This is what you hold up or call out during the auction to place your bids. Keep it visible and accessible throughout the auction.

Registering as a Buyer's Agent or Representative

If you cannot attend the auction in person, or prefer to have a professional handle the bidding, you can have someone bid on your behalf. This requires:

Written authority — a signed letter or authority form naming the person who will bid for you, including their full name and ID details
Your identification — copies of your photo ID must still be provided
The representative's identification — they must also present their own photo ID at registration

Many buyers engage a buyer's agent (also called a buyer's advocate) to bid for them. The buyer's agent registers using their own ID plus your written authority. This is common practice and auction staff are well accustomed to it.

Online vs In-Person Registration

In-Person Registration

The traditional method. You show up on auction day, complete the paperwork, present your ID, and receive your bidder number. This is straightforward but requires you to be physically present before the auction starts.

Online or Pre-Registration

Many agencies and auction platforms now offer online pre-registration. This is especially common for auctions conducted via online bidding platforms. The process typically involves:

Creating an account on the auction platform
Uploading copies of your photo ID
Entering your solicitor or conveyancer details
Agreeing to the terms and conditions of the auction
Receiving confirmation of your registration via email

Online pre-registration saves time on auction day and is essential if you plan to bid remotely. Even for in-person auctions, some agents offer pre-registration to speed up the process on the day.

What Happens After You Register

You Can Now Bid

Once registered, you are legally entitled to bid at the auction. Your bidder number is your ticket to participate.

You Are Not Obligated to Bid

Registration does not commit you to placing a bid. You can register, observe the auction, and choose not to bid if the price exceeds your budget or the competition is too strong. There is no penalty for registering and not bidding.

If You Win

The moment the hammer falls in your favour, you have entered a legally binding contract. You will be asked to:

Sign the contract of sale immediately
Pay the deposit — typically 10% of the purchase price
Exchange details with the selling agent for settlement, which usually occurs 30-90 days later

There is no cooling-off period for auction purchases in any Australian state or territory.

If You Do Not Win

If you were outbid, the selling agent may contact you after the auction. If the property passes in (does not meet the reserve), the highest registered bidder gets first right to negotiate with the vendor.

Tips for First-Time Auction Registrants

Review the contract before auction day. Have your solicitor or conveyancer review the contract of sale well in advance. Do not leave this to the morning of the auction.

Know your budget before you register. Setting a clear maximum bid before you arrive prevents auction fever from taking over. Smart Bid's auction planner helps you define your budget zones — comfort, stretch, and absolute limit — so you walk in with a clear plan.

Bring everything in a folder. Photo ID, pre-approval letter, solicitor details, deposit cheque — organise these the night before. Fumbling for documents at the registration desk adds unnecessary stress.

Ask questions at registration. If anything is unclear about the auction conditions, vendor bids, or settlement terms, the registration desk is the right time to ask. The selling agent is required to answer your questions.

Register even if you are unsure. If you are on the fence about bidding, register anyway. You can always choose not to bid, but you cannot bid if you are not registered. Missing out because you hesitated at the registration desk is an avoidable regret.

Consider a practice run. Attend one or two auctions as a spectator before your first real bid. Watch the registration process, observe how bidders interact with the auctioneer, and get comfortable with the pace and format.

Preparing Beyond Registration

Registration is just one piece of auction-day preparation. To give yourself the best chance of success, combine it with thorough research on comparable sales, a building and pest inspection, and a clear bidding strategy.

Use Smart Bid's auction planner to set up your budget zones and track the live bidding against your limits in real time. Having your numbers locked in before you register takes the guesswork out of the most high-pressure property transaction you will face.
