Gazumping in NSW: What It Means and How to Reduce the Risk
A verbally accepted offer does not guarantee that a property is secured. Until contracts are exchanged, another buyer can make a stronger offer, leaving the original buyer at risk of losing the property and any money already spent on inspections or legal advice. For a buyers agent in Sydney, understanding how gazumping works is important in navigating competitive property negotiations.
BMC Buyers Agency approaches the process with a clear strategy, from assessing an offer to moving towards contract exchange. Knowing when a seller can accept another offer and what steps can reduce this risk allows buyers to respond quickly without making rushed decisions.
Gazumping can occur at different stages of the buying process, but the risk exists before contracts are exchanged. Knowing how the process works, what protections apply and how to prepare can help buyers move towards a secure purchase more efficiently.
What Does Gazumping Mean in NSW?

Gazumping in New South Wales occurs when a seller verbally accepts one buyer’s offer but later accepts a higher or more attractive offer from another buyer before contracts are exchanged. The original buyer can lose the property and may also be left out of pocket for costs such as building inspections, legal advice or finance-related expenses.
A verbal agreement, accepted offer or holding deposit does not provide the same protection as an exchanged contract. Until exchange, the seller can consider other offers and choose which buyer to proceed with.
The period between offer acceptance and contract exchange is therefore the main risk period. Buyers who have finance, legal advice and due diligence organised early can reduce the amount of time a property remains unsecured.
Understanding what happens after an offer is accepted can help buyers prepare for contract review, finance and due diligence before delays leave the property exposed to competing offers.
Is Gazumping Legal in NSW?
Yes, gazumping is legal. A seller can accept another offer before contracts have been formally exchanged, even if an earlier offer has been verbally accepted or the buyer has already spent money on inspections or legal advice. Until exchange, the seller is not usually legally bound to proceed with the first buyer.
NSW Government guidance on gazumping explains that sellers may negotiate with other buyers before contracts are exchanged and that buyers are not generally reimbursed for inspection, legal or finance-related expenses if they are gazumped.
Once contracts are exchanged, the situation changes. The buyer and seller are bound by the contract, subject to any applicable cooling-off rights and the terms of the agreement. The seller cannot simply accept a higher offer from another buyer and disregard the existing contract.
Selling agents must still comply with their legal obligations, including passing offers on to the seller and avoiding misleading or deceptive conduct. Buyers benefit from moving from an accepted offer to contract exchange as quickly as practical.
When Can a Buyer Be Gazumped?
A buyer can be gazumped at any point before contracts are formally exchanged. The greatest risk is usually after an offer has been accepted but while the buyer is still arranging finance, reviewing the contract or completing due diligence.
Delays during this stage can give another buyer an opportunity to make a more attractive offer. Once contracts have been exchanged, the seller is bound by the agreement, so accepting another buyer’s higher offer does not normally allow the original contract to simply be replaced.
At auction, the circumstances are different because there is no cooling-off period. Similarly, a buyer who exchanges under a Section 66W certificate gives up the standard cooling-off period. These options should only be considered after appropriate legal advice.
Before waiving the cooling-off period, buyers should complete the necessary legal, finance and property checks because the contract may become unconditional immediately after exchange.
When Does a Property Purchase Become Legally Binding?
A property purchase becomes legally binding when contracts are formally exchanged. Before exchange, an accepted offer, holding deposit or completed inspection does not usually prevent the seller from considering another buyer.
At exchange, the buyer and seller enter into a binding contract for the property. The contracts are signed and exchanged by the parties’ legal representatives, with the deposit paid according to the contract arrangements. From this point, the seller cannot simply accept a higher offer and disregard the existing contract.
For most eligible private treaty residential purchases, the buyer may have a five-business-day cooling-off period after exchange, subject to applicable exceptions. This does not mean the contract only becomes binding after cooling-off. Instead, the buyer has a limited statutory right to rescind during that period, subject to a 0.25% penalty.
Auction purchases do not include a cooling-off period. Buyers should therefore have the contract reviewed by a solicitor or licensed conveyancer before exchange and understand the applicable terms and rights before proceeding.
What Happens If a Seller Accepts Another Offer?
If a seller accepts another offer before contracts have been exchanged, the original buyer may still have an opportunity to proceed. The seller can choose the offer that best suits their circumstances, considering factors such as price, finance certainty, settlement terms and how quickly the buyer can proceed.
The original buyer can consider the following steps:
- Confirm the contract status: Ask the selling agent whether contracts have been exchanged with the competing buyer. If exchange has not occurred, there may still be an opportunity to negotiate.
- Reassess the offer: A higher price, preferred settlement terms or evidence of finance readiness may make the original offer more attractive. Any revised offer should remain within the buyer’s budget and reflect the property’s value.
- Move quickly: If the seller remains open to the original buyer, having legal advice, finance and key due diligence ready can help move towards exchange without unnecessary delays.
- Avoid emotional bidding: Being gazumped can create pressure to offer more than the property is worth. Comparable sales, finances and the property's suitability should remain the basis for any revised offer.
- Know when to walk away: If contracts have already been exchanged or the revised terms no longer represent good value, pursuing another property may be the more sensible option.
If contracts have already been exchanged with another buyer, the seller is bound by that agreement. A solicitor or conveyancer should advise on the specific circumstances and any available options.
Can a Deposit Protect a Buyer From Gazumping?
No. A deposit alone does not protect a buyer from gazumping. A holding deposit paid before contracts are exchanged does not create a binding sale or prevent the seller from accepting another offer. The key protection comes from exchanging contracts, rather than simply paying money to the selling agent.
Once contracts are exchanged, the buyer and seller are bound by the agreement, subject to any applicable cooling-off rights and contract terms. For eligible private treaty purchases, a buyer may have a five-business-day cooling-off period and can withdraw during that period.
Buyers should focus on being contract-ready rather than relying on a holding deposit to secure the property. Having finance, legal advice and important due diligence organised can help shorten the time between offer acceptance and contract exchange.
What Should Buyers Check Before Making an Offer?
Checking key details before making an offer can help buyers make decisions and move more quickly if the offer is accepted. It can also reduce delays during the period before contracts are exchanged.
Before making an offer, buyers should consider:
- The contract for sale: Have a solicitor or licensed conveyancer review the contract where possible, including title details, easements, restrictions, inclusions, exclusions, settlement terms and special conditions.
- Finance and budget: Confirm borrowing capacity, available funds and a maximum purchase price before negotiations begin.
- Property condition and risks: Arrange appropriate pre-purchase inspection reports and consider strata records, zoning, development restrictions, flood or bushfire risks and other factors that could affect the property’s use or value.
- Comparable sales: Review recent sales of similar properties to establish whether the asking price is reasonable and set an offer limit based on market evidence.
- Key professionals: Have a solicitor or conveyancer, mortgage broker, lender and relevant inspectors ready to act so important checks can progress quickly if the offer is accepted.
Preparing these matters early allows buyers to approach negotiations with a clear budget and a realistic understanding of the property. It also reduces the time needed to move from an accepted offer to contract exchange.
How Can Buyers Reduce the Risk of Being Gazumped?
Buyers cannot completely eliminate the risk of gazumping, but preparation can reduce the time a property remains unsecured. The main priority is to be ready to move from an accepted offer to contract exchange as quickly as practical.
Be Ready Before Making an Offer
Finance should be pre-approved, a solicitor or licensed conveyancer should be engaged and key property checks should be arranged early. Building and pest inspections, strata searches and other due diligence can also be prepared in advance where appropriate.

Having these steps organised allows buyers to respond quickly if an offer is accepted and demonstrates to the selling agent that the buyer is ready to proceed.
Exchange Contracts Quickly
Once an offer is accepted, contracts should be reviewed, signed and exchanged promptly. For eligible private treaty purchases, a buyer can use the statutory five-business-day cooling-off period after exchange.
This period can provide an opportunity to finalise certain matters after exchange, but buyers should obtain legal advice before relying on it, particularly where risks remain outstanding.
Keep Communication Clear
Clear timeframes and prompt communication with the selling agent can help prevent unnecessary delays. Buyers should respond quickly to contract queries, arrange inspections promptly and keep their solicitor, lender and other professionals ready to act.
Regular communication can also provide early warning if another buyer becomes interested. Acting quickly when circumstances change can help reduce the opportunity for a competing offer to overtake the original negotiation.
What Should Buyers Do If They Are Gazumped?
Being gazumped can be frustrating. However, if contracts have not yet been exchanged with the competing buyer, there may still be an opportunity to negotiate.
The first step is to confirm whether the competing offer has progressed to exchange, then decide whether the property is still worth pursuing. Buyers should avoid making rushed financial decisions simply because another offer has been made.
If the property is still available, buyers can:
- Confirm the contract status: Ask the selling agent whether contracts have been exchanged with the other buyer. If exchange has not occurred, the original buyer may still be able to make a revised offer.
- Reassess the offer: Consider whether a higher price, preferred settlement terms or evidence of finance readiness would strengthen the offer. Any revised terms should remain within the buyer’s budget and reflect the property’s value.
- Know when to walk away: If contracts have already been exchanged or the revised offer no longer represents good value, pursuing another property may be the better option.
For future purchases, having finance, legal advice and key due diligence organised early can help reduce delays between offer acceptance and contract exchange.
How a Buyers Agent Can Help Reduce the Risk
A buyers agent cannot eliminate the risk of gazumping because a property is not secured until contracts are exchanged. However, professional support can help reduce delays, strengthen the buyer’s position and keep the negotiation moving towards exchange.
They can help by:
- Strengthening the offer: The agent can assess comparable sales, the buyer’s budget and the seller’s priorities to help structure an attractive offer. Settlement terms, finance readiness and other conditions can be considered as part of the negotiation strategy.
- Coordinating the process: Finance, contract review, inspections and other due diligence can be organised early so potential delays are reduced. Keeping these steps moving can shorten the period between offer acceptance and exchange.
- Managing communication: The buyers agent can maintain contact with the selling agent, monitor competing interests and respond quickly if the seller receives another offer. Where appropriate, the agent can also negotiate for prompt exchange or other terms that may strengthen the buyer’s position.
Any decision involving cooling-off rights, a 66W certificate or other contract terms should be made with appropriate legal advice. The buyers agent’s role is to help manage the negotiation and timing.
Gazumping can be frustrating for property buyers, especially after an offer has been accepted and money has been spent on inspections or legal advice. Since a sale is not binding until contracts are exchanged, having finance arranged, legal advice ready and key checks completed early can help reduce the risk and shorten the period in which another buyer can step in.
BMC Buyers Agency can help buyers navigate competitive negotiations, assess offers and move efficiently towards exchange. With the right preparation and support, buyers can approach the NSW property market with a clear strategy and greater confidence.
