To avoid being gazumped, a buyer must move the transaction to exchange of contracts as quickly as possible, because gazumping is only possible before a sale becomes legally binding. Under Australian property law, no enforceable rights arise from an accepted offer or verbal agreement. Legal certainty begins only at exchange.
Gazumping is not prevented by goodwill, negotiation strength, or assurances from an agent. It is prevented by legal finality. Buyers who understand this distinction are far better positioned to protect themselves in competitive property markets.
Buyers are legally exposed to gazumping before exchange because Australian property law does not create enforceable rights or obligations until contracts are formally exchanged. An accepted offer, verbal agreement, or negotiation in principle does not bind the seller or prevent the acceptance of a higher offer.
During this pre-exchange period, the buyer has no contractual or proprietary interest in the property, while the seller remains legally free to withdraw or renegotiate. This legal gap between agreement and exchange is what allows gazumping to occur and why buyers who delay legal preparation face increased exposure.
The most effective way to avoid being gazumped is to shorten the period between offer acceptance and exchange of contracts. From a legal perspective, gazumping cannot occur once contracts have been exchanged.
Every delay increases risk. Every day without exchange preserves the seller’s legal freedom to accept another offer. Buyers who prioritise early exchange significantly reduce their exposure.
Avoiding gazumping begins before an offer is made. Buyers who engage legal support early are structurally less vulnerable.
Key legal preparation steps include:
These steps allow a buyer to proceed directly to exchange once terms are agreed, often with guidance from professionals who can find a property lawyer experienced in pre-exchange risk management.

Contracts should be exchanged as soon as legally practicable after an offer is accepted, because the risk of gazumping exists only before exchange occurs. The longer the delay between agreement and exchange, the greater the seller’s legal ability to accept a competing offer.
In competitive markets, exchange often needs to occur within days rather than weeks. Delays caused by late contract review, unresolved finance conditions, or slow legal engagement extend the pre-exchange window and materially increase the risk of gazumping.
Conveyancers play a central legal role in gazumping prevention by enabling early exchange.
Their responsibilities include:
Buyers who delay engaging a conveyancer often lose the ability to exchange quickly, increasing legal exposure.
While only exchange provides legal certainty, certain commercial steps may reduce practical risk.
These include:
These measures do not create legal rights but may discourage competing offers during the pre-exchange phase.
If a buyer is gazumped after an offer is accepted but before contracts are exchanged, the buyer generally has no legal right to force the sale or claim compensation. Because no legally binding contract exists at this stage, the seller is entitled to accept another offer.
In practical terms, the transaction comes to an end, and any pre-exchange costs—such as building inspections or legal advice—are usually unrecoverable. Legal remedies are only available in limited cases involving misleading or deceptive conduct, which require clear evidence.
Yes, gazumping is generally legal because Australian law does not impose obligations until exchange. Ethical considerations vary, but legality is determined strictly by contract law principles, which answer the question is gazumping legal in most circumstances.
Property law prioritises:
Buyers are expected to protect their interests procedurally rather than rely on good faith.

First-time buyers are particularly exposed due to unfamiliarity with legal thresholds.
Common misconceptions include:
Education and early legal advice are the most effective safeguards for first-time purchasers.
Some insurance products may cover limited pre-exchange costs if a buyer is gazumped. However, insurance does not prevent gazumping and does not create enforceable rights.
Insurance should be viewed as cost mitigation only, not legal protection.
Both practices arise from the same legal framework.
Gazumping
Gazundering
Both are lawful because negotiations remain non-binding until exchange.

The following questions address common legal concerns.
By reducing the time between offer acceptance and exchange of contracts through early legal preparation.
Engaging a conveyancer early, reviewing the contract in advance, and moving quickly to exchange.
As soon as practicable after agreement, particularly in competitive markets.
Usually no, unless misleading or deceptive conduct can be proven.
Yes. It is more common where demand is high and exchange is delayed.
To avoid being gazumped, buyers must prioritise legal timing over negotiation comfort. Until contracts are exchanged, no enforceable rights exist, regardless of how firm an agreement appears.
Buyers who engage legal professionals early, prepare contracts in advance, and move decisively to exchange significantly reduce their risk.
