Cooling-off periods by state: how long you have to walk away after signing

You signed the contract on Saturday afternoon. Sunday morning the building inspector calls back with a list of problems you didn't see at the open home. The question that decides whether you lose $2,000 or $85,000 is a simple one: which state is the property in, and was it sold under the hammer.

Cooling-off is the statutory right to terminate a signed property contract within a defined window, usually for a small penalty. It is not the same thing as a subject-to-finance clause, and it doesn't exist at all in two states. Here is the honest map across all eight jurisdictions.

The state-by-state table

Every state and territory writes the rules into its own statute. The numbers below are the headline cooling-off window for a private-treaty residential purchase, plus the penalty if the buyer pulls out inside the window.

• NSW: 5 business days. Section 66S Conveyancing Act 1919. Penalty if the buyer rescinds: 0.25% of the purchase price. Auction sales have no cooling-off period.
• VIC: 3 business days. Section 31 Sale of Land Act 1962. Penalty: $100 or 0.2% of the price, whichever is greater. No cooling-off on auctions, or on private sales signed within 3 clear business days before or after a scheduled auction.
• QLD: 5 business days. Property Occupations Act 2014. Penalty: 0.25% of the price. Auction contracts (signed on the day or within 2 clear business days afterwards) have no cooling-off.
• SA: 2 clear business days.Land and Business (Sale and Conveyancing) Act 1994. The clock only starts when the Form 1 vendor's statement is correctly served on the buyer, which is the quirk that catches people out. Bid at auction and you have no cooling-off; sign post-auction and you do.
• WA: none.No statutory cooling-off period exists in Western Australia. The contract is binding from the moment both parties sign. Buyers rely entirely on negotiated "subject to" clauses for protection.
• TAS: none. Tasmania removed its statutory cooling-off period in a 2007 reform and has never reinstated it. Same posture as WA: negotiate your conditions into the contract before you sign.
• ACT: 5 business days. Civil Law (Sale of Residential Property) Act 2003. Penalty: 0.25% of the price, with a cap of $1,000 applying in some instances. Auctions are excluded.
• NT: 4 business days. Law of Property Act. Penalty: 0.25% of the price.

A worked example: Sydney, $850,000, day-four cool-out

A buyer signs an unconditional NSW contract on a Friday afternoon for $850,000. The cooling-off period is 5 business days, so the window closes the following Friday at 5pm. On Wednesday (day four) the building-and-pest report lands and flags structural movement in the rear wing that the agent never mentioned at the open.

The buyer instructs their solicitor that evening to serve a written notice of rescission on the vendor's representative. Notice is served Thursday morning, well inside the window. The buyer forfeits 0.25% of the purchase price as the statutory penalty.

• Purchase price: $850,000.
• Penalty: 0.25% × $850,000 = $2,125.
• Deposit returned: balance of the 0.25 deposit, less $2,125.
• Total cost of walking away: $2,125.

Compare that against the alternative of going through to settlement and discovering the same structural issue with the keys in hand. $2,125 is a rounding error against a remediation quote that could easily start at $40,000. That is what the cooling-off mechanism is for.

What "business day" actually means

A business day excludes Saturdays, Sundays, and public holidays in the relevant state or territory. The fiddly bit is when the clock starts. Most states count from the day after the contract is signed and exchanged, but the precise trigger and the treatment of the day of signing varies, and a national public holiday landing mid-window (think Easter or ANZAC Day) pushes the deadline out.

Two days in SA is genuinely two days. Five days in NSW with a King's Birthday Monday in the middle is closer to a week. Don't assume the agent or the vendor knows the count better than your conveyancer does, and put the deadline in your calendar in writing the same day you sign.

How to invoke it

Rescission has to be in writing, served on the vendor or the vendor's agent or solicitor, and delivered before the cooling-off window closes. A phone call doesn't count. A text message is risky. The clean path is a letter or email drafted by your conveyancer or solicitor and served per the contract's notice clause.

Keep the proof of service. If the vendor disputes that notice was delivered in time, the burden falls on the buyer to show the email timestamp, the registered-post receipt, or the courier's delivery confirmation. A "subject to" clause is private contract law between the parties; cooling-off is a statutory right that the vendor cannot waive away in the fine print.

Cooling-off vs subject-to clauses

These are different tools, and buyers conflate them constantly. Cooling-off is a default statutory right that exists the moment you sign (in six of eight jurisdictions). It is short, it has a penalty, and it goes away the day you pass the window.

Subject-to-finance, subject-to-inspection, and subject-to-sale clauses are negotiated contract provisions. They run for whatever period the parties agree (often 14 to 21 days for finance, 7 to 14 for inspection), they usually have no penalty if the condition genuinely isn't satisfied, and they survive past the cooling-off window. In WA and Tasmania they are the only protection you get; everywhere else they layer on top.

Why auctions have no cooling-off

The bidding process is treated as the negotiation. The winning bidder commits unconditionally on the fall of the hammer, the contract is signed in the room, and there is no walking away the following Monday. That is the trade you accept when you raise a paddle.

It also explains why pre-auction due diligence is non-negotiable. Building-and-pest, strata report, contract review, and finance pre-approval all have to be done before bidding day, not after. For the deeper case on whether the auction format itself is even the right call, the auction vs private treaty comparison is worth a read. The building-and-pest guide covers what an inspection actually catches and what it doesn't.

Extending the window

In NSW, VIC, QLD and the ACT the buyer's solicitor can request an extended cooling-off period (commonly 10 business days instead of the statutory 3 or 5) and write it into the special conditions before exchange. It requires vendor agreement, which is rare in a hot market and routine in a soft one. If the property has been on for six weeks with no offers, ask. If it has had four inspections in five days, don't expect a yes.

The other lever is a section 66W certificate in NSW, which intentionally waives the cooling-off period rather than extending it. Vendors sometimes demand a 66W as a condition of accepting your offer, especially on competitive listings. Signing one means surrendering the statutory right entirely, so do it with eyes open and only after due diligence is finished.

WA and Tasmania: the no-cooling-off states

Half the country has a safety net. The other half doesn't. In WA and Tasmania the contract binds from signature, full stop. The practical workaround is to negotiate every protective condition you need (finance, inspection, valuation, sale of existing property) into the contract before you sign. Once your name is on the page, the only way out is to satisfy the agent that a condition you wrote in has failed.

Two consequences. First, WA and TAS buyers should never sign on the bonnet of a car at the open home. The contract goes to the conveyancer or settlement agent first, who marks it up, then to the agent, then back to the buyer. Second, building-and-pest needs to be either ordered as a condition of the contract or completed before signing. There is no five-day grace period to discover the slab is cracked.

The full upfront-cost stack

Cooling-off is one of several things that decides whether a signed contract is actually a deal. The other big ones are stamp duty and the total cash you need on day one. The buying-cost calculator rolls duty, LMI, conveyancing and inspections into a single number, and the conveyancer vs solicitor breakdown is useful for picking who serves the cooling-off notice if you ever need to.

The right to walk away is short and it isn't free, but it exists for a reason. Use the window for proper inspections and proper legal review, and the 0.25% penalty stops looking expensive the moment the inspector finds something worth $40,000.
