Cooling Off Period When Buying a Home and How It Works

You signed the contract on a Friday afternoon, and by Saturday morning the doubts arrived: the building report is not back, your broker has gone quiet, and you are no longer sure about the street. The cooling off period when buying a home exists for exactly this moment, but it is shorter, narrower and more expensive to use than most buyers assume.

This guide explains how the cooling off period works across Australian states, what it costs to walk away, when you do not get one at all, and how to use those few days properly rather than just waiting them out.

What the cooling off period actually is

A cooling off period is a short window after you sign a contract for a residential property during which you can cancel, usually without needing a reason. It applies to the buyer only. The seller cannot use it to back out because a better offer turned up.

Three details trip people up:

It starts when the contract is exchanged or signed, not when you made the offer or when the agent rang to say it was accepted.
It counts business days, so public holidays and weekends do not count, and the deadline is usually 5:00 pm on the last day.
Cancelling is not free. In most states you forfeit a small percentage of the price.

Cooling off period rules by state

The rules differ across Australia, and they change from time to time, so always confirm the current position with your conveyancer. As a general guide:

State or territory	Length	Cost to cancel
New South Wales	5 business days	0.25 percent of the price
Victoria	3 business days	0.2 percent of the price or 100 dollars, whichever is more
Queensland	5 business days	0.25 percent of the price
South Australia	2 clear business days	Up to 100 dollars
ACT	5 business days	0.25 percent of the price
Northern Territory	4 business days	Generally no penalty
Western Australia and Tasmania	No statutory period	Depends on contract conditions

On an 850,000 dollar house in Sydney, the 0.25 percent penalty is 2,125 dollars. That is real money, but far less than the deposit you could lose by failing to settle later.

When you get no cooling off period at all

This is the part that catches people. In most states there is no cooling off period if:

You buy at auction. The fall of the hammer is final.
You sign on auction day, or within a set window before or after it, in some states. In NSW and Victoria, buying a property that was passed in at auction on the same day usually has no cooling off.
You waive it. In NSW, your solicitor can issue a certificate that removes the cooling off period, often to make your offer more attractive. Some agents push for this.
The buyer is a company, in certain states.

If any of these apply, every check you would normally do during cooling off has to happen before you sign. That means building and pest reports, strata records and finance approval all need to be done first. Our guide to the building inspection items that actually matter shows what to prioritise when time is short.

How to use the cooling off days well

Five business days goes quickly. Treat it as a deadline for specific tasks, not as thinking time.

Day 1: Book the building and pest inspection immediately. Good inspectors are often booked two or three days out.
Day 1: Send the contract to your conveyancer or solicitor if you have not already, and ask them to flag any special conditions.
Day 2: Confirm with your lender that formal approval is on track, and ask whether they need a valuation. If the valuation might come in short, you need to know now.
Day 2 to 3: For apartments and townhouses, order or read the strata report. Look for special levies, defect claims and low sinking funds.
Day 3 to 4: Review reports with your conveyancer. Decide whether to proceed, renegotiate or cancel.
Before 5:00 pm on the last day: If cancelling, deliver written notice in the exact way the contract requires.

The case against waiving your cooling off period

In a hot market, agents often suggest that waiving the cooling off period will help your offer win. Sometimes that is true. But the usual advice to "waive it to look serious" is overrated, for one practical reason: the seller rarely gains much.

From the seller's side, a buyer who uses the cooling off period to cancel pays a penalty and leaves. The property goes back on the market a week later. Annoying, but not a disaster. From your side, waiving means losing your safety net on a decision worth hundreds of thousands of dollars.

A better tactic is to finish your checks before you sign: get the inspection done, read the contract with your conveyancer, and have finance approval in hand. Then offer a shorter cooling off period or a clean contract with no extra conditions. You look just as serious, and you have actually done the work. Our list of questions to ask before making an offer helps you do that groundwork fast.

How to cancel properly

If you decide to walk away, the method matters. Most contracts require written notice delivered to the seller or the seller's agent or solicitor before the deadline. Email may or may not count, depending on the contract and the state. Let your conveyancer send it, keep proof of delivery, and do not rely on a phone call to the agent. The penalty is usually taken from your deposit, and the balance is refunded.

Timing is unforgiving. Notice that arrives at 5:05 pm on the last day is generally too late, and you are then bound by the contract. If the deadline falls on a day your conveyancer is unavailable, arrange a backup the day you sign. And if you only paid a small holding deposit during cooling off, check how the penalty is calculated, because you may owe the difference.

Frequently asked questions

Can the seller pull out during the cooling off period?

No. In Australian states with a statutory cooling off period, it protects the buyer only. Once contracts are exchanged, the seller is bound unless a condition in the contract allows them to end it.

Do weekends count in the cooling off period?

Generally not. Cooling off periods are counted in business days, so weekends and public holidays are excluded. A contract signed on a Thursday in NSW typically runs until 5:00 pm the following Thursday.

Can you negotiate a longer cooling off period?

Yes, the buyer and seller can agree to extend it, and this is common when an inspection or strata report cannot be done in time. Ask for the extension in writing before you sign, as sellers rarely agree once the clock is running.
