Thinking about buying or selling at auction, but not sure how it all works? Whether you're attending your first auction or considering listing your property this way, understanding the process is key to success. In this guide, we’ll explain how auctions work in Australia, what to expect on auction day, and how to prepare—whether you're buying or selling.

What Is an Auction?

Defining Auctions

An auction is a public sale where a property is sold to the highest bidder. It’s a fast-paced, transparent method commonly used in Australia’s real estate market. The auction takes place at a set time and location (often onsite or online), with buyers competing in real-time to purchase the property.

Why Auctions Are Popular in Australia

Auctions offer a clear timeline, drive competitive bidding, and create urgency among buyers. For sellers, this often leads to strong sale prices and unconditional contracts. For buyers, auctions provide transparency and a fair shot at securing the property.

Common Auction Terminology Explained

Understanding these common auction terms will help you feel more confident at the auction:

• Reserve Price – The minimum price a seller is willing to accept. If bidding doesn’t reach this, the property may not be sold.

• Passed In – If the highest bid doesn’t meet the reserve price, the property is “passed in” and may go to post-auction negotiation.

• Opening Bid – The first bid made to kick off the auction. It can come from the crowd or the auctioneer.

• Vendor Bid – A bid made on behalf of the seller, often used to start or guide bidding. It must be clearly declared.

• Unconditional Sale – A binding contract with no cooling-off period. Common for auction purchases.

• Hammer Price – The final price when the auctioneer brings down the hammer, indicating the winning bid.

• Bidders Guide – A document or brochure provided before the auction to help buyers understand terms, rules, and property details.

• Auctioneer – The licensed professional who conducts the auction and oversees the bidding process.

Pro tip: Ask your agent for clarification on any terms before auction day to avoid surprises.

How property Auctions Work in Australia

Step-by-Step Auction Process for Buyers

1. Inspect the Property - Attend opoen and building/pest inspections ahead of time
2. Review the contract and Get Legal Advice - Contracts are final and binding once the hammer falls.
3. Ensure Finance and Pre-Approval - Have home loan pre-approval in place
4. Register to Bid - Provide ID to receive a bidder number from the agent
5. Bid with Confidence - Bidding begins, the reserve is announced, and the hammer falls to close the sale.

Home Loan Pre-Approval: Why it's Essential

• Unconditional Contract: Once the hammer falls, there's no cooliing-off-desposit (~10%) and contract exhange are immediate
• Finance Must be Ready: Without pre-approval, you may lose your deposit or face legal consequences, including forfeiture of the despooit and claims for damages.

What Sellers Should Know

Benefits of Selling by Auction

• Creates urgency with a fixed sale date

• Sparks competitive bidding

• Delivers unconditional sales when sold on the day

Setting the Reserve Price

The reserve is the undisclosed minimum you're willing to accept. If not reached, the property is passed in, and negotiations may continue.

Tips for Bidding at Auction

• Do Your Research – Investigate comparable sales in the area.

• Stay Within Budget – Write down your top bid beforehand.

• Know the Rules – Seek clarity on deposit, bidding increments, ID.

• Bring ID and Deposit – Have identification and a bank cheque/Cheque ready.

What Happens If a Property Is Passed In?

If the auction doesn't reach the reserve:

• The property is passed in and auction ends.

• The highest bidder usually has first negotiation rights.

• It may later be listed privately.
