Cooling-off is the part of a residential purchase that buyers remember from a friend's story and then apply to the wrong contract. The friend's story was probably a private treaty sale in a particular state in a particular year. Your contract is a different document. The method of sale matters more than the suburb, and the state matters more than the method of sale. A buyer's agent can keep you out of the obvious traps. They cannot be your solicitor.

Two high-level facts are worth putting at the top of the fridge. Auctions in Australia generally have no cooling-off period. Once the hammer falls, you are typically bound. Private treaty sales often do have a cooling-off period, and the length varies by state. New South Wales commonly allows five business days on many residential private-treaty purchases. Victoria commonly allows three clear business days. Other states and territories set different rules, and some have no statutory cooling-off at all. Readers must confirm the current position with their conveyancer or solicitor. This article is general information, not advice, and not a substitute for the Act or the contract in your hand.

This guide sits in our buying process hub. It explains how the two methods of sale treat second thoughts, where a licensed buyer's agent fits, and which parts of due diligence you should never park in a cooling-off window that might not exist. For the auction choreography, read using a buyer's agent at auction. For the paperwork you sign with the agent themselves, see the buyer's agency authority in the fees hub.

Private treaty is a conversation with a clock

Private treaty means the property is offered for sale at a price, or in a price guide, and you make an offer. If the vendor accepts, you exchange contracts. In several states that exchange is not the end of your ability to walk away. A statutory cooling-off period, where it exists, gives the buyer a short window to terminate, usually with a small prescribed penalty rather than the full deposit.

The length, the way days are counted, the time of day the window ends, who can waive it, and what it costs to use it are all local. New South Wales commonly uses five business days for many residential private-treaty contracts. Victoria commonly uses three clear business days. Queensland, South Australia and the Australian Capital Territory have their own residential frameworks. Western Australia, Tasmania and the Northern Territory are often described, at a high level, as having no general statutory cooling-off for ordinary residential sales unless the contract itself provides one. That sentence is exactly the sort of sentence that goes stale. Confirm it. Do not quote this paragraph to a selling agent as if it were a ruling.

Counting is where people lose days they thought they had. "Business days" and "clear business days" are not the same phrase. Weekends, public holidays and the hour the clock stops — often 5pm — are easy to get wrong if you are counting on your fingers after a Saturday inspection. Your conveyancer will count. Let them.

Waiving cooling-off is a legal act, not a vibe. In states where a waiver or shortening is possible, it typically requires a certificate from a solicitor or conveyancer in a prescribed form. A selling agent who says "just sign here and we will skip cooling-off" is asking you to give away a statutory protection. A buyer's agent who agrees because it will "win the deal" is working the vendor's timetable. There are situations where a well-advised buyer will waive, usually because due diligence is already finished and the competitive position requires it. That is a conversation with your lawyer, with the inspection reports on the table, not a conversation in a doorway.

Terminating during cooling-off, where the right exists, usually costs a small percentage of the price rather than the whole deposit. The figure is prescribed and it changes. Do not guess it. Do not spend it as if it were a booking fee for a house you have already emotionally moved into.

Auction is designed to remove the clock

An auction is a public competition with a reserve. If you are the highest bidder above the reserve, you have generally bought the property when the hammer falls. You sign, you pay the deposit on the contract's terms, and you proceed to settlement. There is typically no cooling-off. That is not a quirk of one postcode. It is a feature of the method of sale across the country, with local wrinkles your lawyer will name.

The practical consequence is brutal and useful. Everything you would have done during cooling-off on a private treaty file — building and pest inspections, a proper contract review, a finance conversation that matches the limit — has to happen before you bid. Building and pest reports are the buyer's choice. They are strongly advisable. An auction campaign that leaves no time for them is not a reason to skip them. It is a reason to let this one go.

Passed-in properties confuse people. The auction failed. The selling agent now wants to talk. That conversation looks like private treaty, and sometimes it is. Sometimes, especially if you were a registered bidder and you sign on the same day, the contract is still treated as an auction sale for cooling-off purposes. Do not assume a failed auction has gifted you five business days. Ask before you sign on the bonnet.

Off-market stock follows the method of sale, not the absence of a Domain listing. A quiet private treaty may still carry cooling-off. A quiet auction, or a sale on auction terms, generally will not. See off-market properties.

Where the buyer's agent sits — and where they do not

A licensed buyer's agent should know which method of sale they are walking you into, and should schedule due diligence accordingly. On a private treaty file they negotiate price and conditions, including whether the vendor will wait for inspections, and they should not treat cooling-off as a plan A for work that could have been done last week. On an auction file they hold a written limit and they do not bid as if Saturday were a rehearsal.

They cannot give you legal advice about whether to waive. They cannot sign a 66W-style certificate, or its Victorian equivalent, unless they are also your lawyer, which they should not be. They cannot promise that a particular penalty will apply. They can put the contract in front of your conveyancer on Tuesday instead of Friday. That, by itself, is often worth a conversation about fees.

They also cannot fix a bad authority with a cooling-off story. The buyer's agency authority is a different document from the contract of sale. Cooling-off on the purchase, where it exists, does not automatically unwind the fee you agreed to pay the buyer's agent. Ask what happens if you terminate the purchase during cooling-off. Ask what happens if you find the home yourself. Unclear success fees are a red flag, and they live in the authority, not in the Conveyancing Act.

Inspections, finance and the misuse of the window

The worst use of cooling-off is as a substitute for courage. Buyers exchange because the selling agent said another offer was coming, then spend the statutory window trying to assemble a building report, a pest report, a lender and a personality. Sometimes that works. Often it produces a frantic termination and a penalty, or a decision to proceed because the penalty feels like money already spent.

Do the inspections first when you can. If the vendor will not allow them before exchange, that is information about the vendor. If your buyer's agent says there is no time, ask whose diary is being protected. Pressure to skip inspections is one of the oldest tells in the business. Independent reports remain your choice and remain strongly advisable in every state.

Finance is the other misuse. Cooling-off is not a substitute for a pre-approval that matches the price. Lenders move on their own clocks. A statutory window of three or five business days is a poor place to discover that the bank wanted a different valuation.

How to brief the people around the contract

Hire the buyer's agent, the conveyancer and the inspector as a set, not as a sequence you invent on the weekend. Tell the agent, in the brief, that you will not waive cooling-off unless the lawyer has the reports and says the competitive position requires it. Tell the lawyer which state the property sits in, which is obvious until someone starts sending you a New South Wales template for a Victorian house. Tell the inspector when the auction is, because a report delivered on Monday after a Saturday hammer is a souvenir.

Check that the buyer's agent is licensed on the public register in that state. Licence registers exist in each state and territory. REBAA is a professional association, not a regulator, and not a source of cooling-off law. Exclusive buyer agents should not take vendor commission on the same deal; a person paid by the seller is poorly placed to tell you to slow down.

If the whole apparatus feels like more machine than the purchase needs, you may be in a quiet private treaty on a house you already understand. In that case read when you do not need a buyer's agent and spend the fee on a better inspection and a lawyer who answers the phone.

The short version

Auctions generally have no cooling-off. Private treaty often does, and the length is a state rule — commonly five business days in New South Wales and three clear business days in Victoria, with other jurisdictions doing something else, including nothing statutory at all. Confirm the current rule. Do not use the window as a dumping ground for inspections and finance. A buyer's agent can schedule the work. Your conveyancer owns the advice. The contract in your hand beats any article, including this one.
