What is the cooling-off period when buying property in New South Wales?

A cooling-off period is a set window after signing a contract in which a buyer can withdraw. In New South Wales it lasts five business days (ten for off-the-plan contracts), starting the first business day after the contract date and ending at 5pm on the fifth business day (tenth for off-the-plan).

The cooling-off period is a consumer protection mechanism letting you withdraw within the window without major penalty — time to review the contract, seek legal advice, and confirm the decision suits your best interests. If you rescind during the period, you forfeit 0.25% of the purchase price to the vendor, with the balance of your deposit refunded. You can shorten or extend the period by agreement with the vendor (best done in writing). You can also waive it entirely by providing a Section 66W certificate — this must be signed by your own licensed conveyancer, solicitor or barrister, who has to explain to you the effect of the contract, of giving the certificate, and of waiving the cooling-off period. It doesn't apply if: you've waived it via a 66W certificate; the property is sold by public auction; the contract is entered into the same day the property was passed in at auction; or the contract is formed by exercising an option to purchase. To cool off: notify the vendor before 5pm on the last day — telling your conveyancer alone isn't enough, they need time to pass it on. Don't leave it until the last minute.

NSW · Section 66W Certificate

Cooling-off period in practice (NSW)

In our New South Wales matters, the cooling-off period is one of the most misunderstood parts of a purchase. The most common one is buyers assuming it always applies. It doesn't at a public auction, or where a contract is signed the same day a property is passed in — so buyers who plan to "cool off if needed" can find there's no window at all.

The other is leaving it too late. To rescind, notice has to reach the vendor before 5pm on the last day. We regularly remind buyers that telling us alone isn't enough — we need time to pass it on — so the final afternoon is not the moment to decide.

What we do is confirm early whether a cooling-off period applies, explain the effect before any Section 66W waiver, and act well inside the deadline if you want out.

The takeaway: check whether cooling-off applies to your contract, and never leave the decision to the final hour.
