To bid at a real estate auction, you must first register with a valid photo ID to receive a bidding paddle. Ensure you have finance pre-approval and a strict budget. Call out bids confidently. If you are the highest bidder and meet the reserve price, you win the property.

Buying a house at auction can be an unnerving experience for first home buyers and seasoned investors alike. With the auctioneer’s rapid monotone and intense competition, entering without a solid plan can lead to costly mistakes.

To succeed, you need to understand the rules, evaluate the market, and execute strategic bidding tactics. Below is our chronological guide to mastering property auctions in Australia.

Phase 1 – Pre-Auction Preparation Checklist

Preparing before auction day is critical. Because auctions are fast-paced and legally binding, having your finances, legalities, and paperwork perfectly aligned is your foundation for success.

Secure Finance Pre-Approval

You must secure formal finance pre-approval before bidding. Bidding at an auction is unconditional, meaning you cannot include a “subject to finance” clause. Knowing your exact borrowing power, required deposit, and LVR (Loan-to-Value Ratio) prevents you from defaulting on a legally binding contract.

Complete Building and Pest Inspections

Always order independent building and pest inspections before auction day. Because there is no cooling-off period, you are purchasing the property “as is.” Identifying structural issues or severe pest damage beforehand ensures you don’t inherit a financial burden.

Review the Contract of Sale

Have a licensed solicitor or conveyancer review the contract of sale prior to the auction. If you require specific terms, such as a longer settlement period or a varied deposit percentage, your solicitor must request and negotiate these variations with the vendor’s legal team before auction day.

Register To Bid

You are legally required to register to bid at an Australian property auction. Arrive at least 30 minutes early to complete this process.

Pre-Auction Registration Checklist:

Item NeededPurpose
Valid Photo IDDriver's license or passport to verify your identity.
Proof of ResidencyA recent utility bill or bank statement proving your current address.
Letter of AuthorityRequired only if a proxy, friend, or buyer's agent is bidding on your behalf.
Bidding NumberProvided by the agent post-registration to legally track your bids.

Phase 2: Proven Auction Bidding Strategies

Understanding the auctioneer’s tactics and reading your competitors gives you a massive strategic advantage. Use these actionable bidding tactics to take control of the environment.

Set a Cut-Off Range, Not Just a Price

Instead of picking a single round number (e.g., $800,000), set a strict maximum budget range (e.g., $803,000). Bidding just $1,000 or $2,000 over a competitor’s round-number limit is a proven tactic to win the auction. However, discipline is paramount—be prepared to walk away if the price exceeds fair market value.

Bid Early and Go Strong

Starting with a strong, confident bid can immediately intimidate competitors. This aggressive strategy clears out bargain hunters quickly and signals to the crowd that you are a serious buyer with strong financial backing.

Use Odd-Numbered Increments

Slow down the auctioneer’s momentum by using odd-numbered bid increments. For example, instead of raising the bid by $10,000, increase it by $7,500 or $11,000. This forces the auctioneer to do the math, breaking their rhythmic chant and disrupting your competitors’ flow.

Call Out Your Bids Confidently

Body language and vocal tone are critical. Call out your bids loudly, instantly, and without hesitation. A confident, emotionless demeanor tricks competitors into believing your budget is limitless, often causing them to fold early.

Understand and Counter the “Vendor Bid”

A vendor bid is a bid placed by the auctioneer on behalf of the seller, which must be legally announced. Understand that this is just a tool to keep momentum going and push the price closer to the reserve. It is not a real competing buyer, so do not let it trigger a bidding war against yourself.

Scenario A: The Property is “Passed In”

If the bidding fails to reach the seller’s reserve price, the property is passed in. Crucially, the highest bidder is legally given the exclusive first right to negotiate the purchase price with the seller. Therefore, even if the reserve isn’t met, fighting to be the highest bidder gives you a massive strategic advantage.

Scenario B: You Are the Successful Bidder

When you place the highest bid and it surpasses the reserve price, the auctioneer’s hammer falls. At this exact second, you are legally bound to complete the purchase. There is no turning back.

Phase 3: What Happens When the Auction Ends?

Winning the auction is just the beginning. The post-auction process requires immediate financial and legal execution.

Signing the Unconditional Contract

If you are the highest bidder at the fall of the hammer, you must immediately sign the contract of sale. Because auction sales in Australia are strictly unconditional, there is no cooling-off period. You cannot change your mind or renegotiate terms once the hammer has fallen.

Paying the 10% Deposit on the Spot

You are required to pay the property deposit (usually 10% of the final purchase price) immediately. Acceptable payment methods typically include a bank cheque or electronic funds transfer (EFT).

Warning: If you plan to pay via EFT, you must contact your bank at least 48 hours before the auction to permanently raise your daily transfer limits, ensuring the transaction is not blocked on a weekend.

Arranging Immediate Building Insurance

In many Australian states, the buyer assumes legal risk for the property from the moment the hammer falls. You should arrange building insurance immediately to protect your new asset and satisfy your lender’s ongoing serviceability requirements.


Are you familiar with common auction terms?

There are several jargons associated with property auctions. Understanding these auction terms will make your life a lot easier, if you are planning to buy a property at auctions.

Some of the commonly used auction terms are:

Bidder’s Guide

It’s a document that the auctioneer provides potential buyers before the auction. A bidder’s guide contains details about registration, necessary paperwork, the rules and bylaws of the auction, and privacy laws.

Reserve Price

Set by the vendor or seller prior to the auction, reserve price refers to the minimum price that the vendor is willing to accept for the property. When the bidding fails to meet the reserve price, the property is ‘passed in’, and the vendor has the right to either decrease the reserve price or pull the property off the auction.

Vendor Bid

It’s the bid placed by the auctioneer on behalf of the vendor, usually before the property reaches its reserve price. A vendor’s bid can only be made once and must be announced by the auctioneer.

Dummy Bid

It’s a dishonest bid made by a non-genuine buyer aimed at pushing the bid price up. If proven, dummy bids attract severe legal penalties to the vendor, the bidder, or the agent, whoever is deemed responsible.

Rises and Advances

Generally decided by the auctioneer, it is the amount of money by which the biddings increases at the auction.

On the market

It’s that point during the auction when the bids reach the reserve price, and the auctioneer formally announces that the auction is ‘live’ or the property is ‘on the market’.

Passed In

It refers to the situation where price bids fail to reach the reserve price. As a result, the vendor or auctioneer either withdraws the property from the auction or gives the highest bidder a chance to negotiate the sale of that property.

Successful Bidder

A successful bidder is the one who has placed the highest bid at the ‘fall of the hammer’, and is then obliged to sign the contract of sale.

Fall of the Hammer

The auctioneer will call for final bids at the end of the auction. When potential buyers stop bidding, the auctioneer will count down the ‘fall of the hammer’, after which no further bids can be accepted, and the highest bidder gets to buy the property.


What to do after an auction?

An auction, if there’s no dispute, ends with the fall of the hammer.

The highest bid when the hammer falls is considered the final value of the property, and the buyer who made that bid, now, has a legal obligation to purchase the auctioned property.

If you’re the successful bidder at an auction, you will immediately have to:

Sign and exchange the contract of sale with the seller

You may want to take a final look at the contract before you sign it. Generally, you may not make additional changes to the terms on the contract.

But, say, you want a slightly longer settlement period. This is the time when you want to make that request to the seller. Usually, the sellers don’t accept last minute changes but you never know when it’s your lucky day.

Pay the deposit amount

It’s typically 10% of the final property value, which you can pay with a cheque or a deposit bond. Some may even prefer cash payment.

Get your new property insured immediately

You may want to check with the seller if they are willing to continue the insurance title on the property. If they don’t, you might want to get your new house insured right away.

After exchanging the signed contract and paying the deposit, you will have to:

Get a formal approval

Sit down with your mortgage broker and get formal approval from your lender as soon as possible. You normally have 28 days from the auction date to settle your new house.

Settle the property

On the day of settlement, you will need to pay the balance of the purchase, stamp duty, and legal fees, after which the property is formally, and finally, yours.
