Cooling-off periods explained: what home buyers need to know
Signing a contract to buy a home is a significant commitment, and in most parts of Australia, buyers who purchase through private treaty get a short legal window afterwards to reconsider — known as a cooling-off period. Understanding exactly how long that window lasts, and what it costs to walk away, matters before you sign anything.
In New South Wales, the standard cooling-off period is 5 business days after the contract is exchanged, and if a buyer withdraws during that window, they forfeit a penalty of 0.25% of the purchase price to the vendor. In Victoria, the cooling-off period is shorter, at 3 business days, with a penalty of whichever is greater between $100 or 0.2% of the purchase price — and notably, in Victoria this cooling-off right cannot be excluded or waived by the contract, making it a mandatory protection for buyers. Queensland's cooling-off period runs for 5 business days as well, with a penalty of 0.25% of the purchase price if the buyer withdraws, broadly mirroring the New South Wales approach.
One rule holds true everywhere in Australia without exception: there is no cooling-off period once a property sells at auction, in any state or territory. The moment the hammer falls at or above reserve, the contract is binding immediately, with no window to reconsider — which is one of the real trade-offs buyers take on when they choose to bid at auction rather than negotiate through private treaty.
It is also worth understanding what a cooling-off period is, and is not. It is a short, unconditional right for the buyer to walk away from the contract, at a cost of the relevant penalty percentage. It is not the same thing as a subject-to-finance or subject-to-building-and-pest clause, which are separate conditions that can sometimes be negotiated into a contract and may allow withdrawal without the standard cooling-off penalty if the specific condition is not met — whether those clauses are available, and on what terms, depends on the contract your solicitor or conveyancer negotiates on your behalf.
Business days for cooling-off calculations exclude weekends and public holidays in every state that offers the right, which matters more than it might seem — a contract exchanged late in the week can mean the cooling-off period effectively extends into the following week once weekends are excluded from the count.
