How the Offer and Acceptance Process Works in Western Australia (and Why It Is Different to the Rest of Australia)

By Brendan Leahy, Naked Real Estate®

Buying or selling a home is one of the biggest financial decisions most people ever make. Yet the document that controls the whole thing is often the one people understand the least.

In Western Australia, almost every residential sale is done using an Offer and Acceptance contract, usually just called the O and A. If you have spoken to friends or family in the eastern states, their buying process probably sounded completely different. That is because it is.

I have sold more than 1,500 properties across more than two decades in the same handful of suburbs. In that time I have watched the same misunderstandings cost people money and sleep, almost always because nobody explained the process in plain English before they signed. This is my attempt to do that.

This article is general information, not legal advice. Every transaction is different. If you are unsure about your rights or obligations, get independent legal advice before you sign anything.

Why Western Australia is different

There is a common belief that WA works differently because we have a different land title system. That is not really the case. Australia’s registered land systems are predominantly based on the Torrens model, which began in South Australia in 1858 and was adopted across the country. Each state and territory has its own legislation and procedures, but WA’s simpler contracting process is not explained by a fundamentally different system of land ownership. It is explained by how the sale is put together and who does what.

What actually makes WA simpler is how the sale is put together and who does what:

• In WA, the real estate agent commonly prepares the standard Offer and Acceptance contract and negotiates it between buyer and seller.
• Once both parties agree on the terms, the contract is signed and acceptance is communicated. At that point it is binding.
• After that, a separately licensed settlement agent, or a lawyer, handles the settlement, which is the legal transfer of the property.

In much of the eastern states, a solicitor or conveyancer is involved much earlier, often preparing the contract and a stack of disclosure documents before the property is even advertised. That front-loading is a big part of why their process feels heavier.

WA has a dedicated licensed settlement agent profession that takes over once the contract is formed. That is the practical difference, and it is why selling here can feel refreshingly straightforward.

I will be straight about the flip side of that, because it matters. A simpler process for the transaction also means more of the responsibility sits with you before you sign. That is the honest trade, and the rest of this article is really about how to carry that responsibility well.

The two documents that make up the contract

Most people think they are signing one document. In reality the standard WA contract is usually made up of:

• The Offer and Acceptance (the O and A)
• The Joint Form of General Conditions
• Any annexures
• Any special conditions

The O and A is the part everyone looks at. The Joint Form of General Conditions is just as important, because it carries a large part of the legal rights and obligations that are not written on the front page. Most people never read it. You do not have to read every clause, but you should understand it exists and that it forms part of your agreement.

Page one: the scheduleThe first page holds the commercial terms:

• Property address
• Purchase price
• Deposit
• Settlement date
• Finance details, if any
• Chattels included in the sale
• Buyer and seller details

It looks simple. It is not. Every completed part of that page can affect the parties’ legal rights and practical obligations, and a small error, even a misspelled name, can cause real problems at settlement.

One decision buyers make without realising it: how you hold the title

Look at the first page of the contract and you will see three boxes: sole owner, joint tenants, or tenants in common. If you are buying with someone else, which one you tick matters enormously, and a lot of people tick it without being told what it means.

If you are buying a home with your partner, it is normally done as joint tenants. In simple terms, you both own the whole property together. If one of you passes away, the property automatically stays with the surviving owner. It happens by law and does not depend on what a will says.

Tenants in common works differently. Here, each owner holds a defined share, and those shares do not have to be equal. If one owner passes away, their share does not automatically go to the others. It is dealt with according to their will.

That difference makes tenants in common a useful structure in some situations. Say you are helping one of your children into a property. You might hold it as tenants in common with a third each to you, your partner, and your child. If something later happens to one owner, their third is dealt with by their will, not simply absorbed by the others. It can also offer your child some protection. If they buy with a partner down the track and that relationship later ends, their defined share is the share in play, not the whole home. Sadly that situation comes up more often than it used to.

Blended families are another common reason. If you and your partner each have children from earlier relationships, tenants in common lets each of you leave your own share to your own children through your will.

This is one of those decisions that is simple to tick and hard to unwind. Before you decide how to hold the title, get legal advice, and speak to your accountant too, because there can be tax and estate consequences that are not obvious at the time.

When the contract becomes binding

This is the single most important thing to understand about buying and selling in WA.

The signed O and A becomes a binding contract once acceptance is communicated to the buyer. Not when the deposit is paid. Not after a few days of thinking it over. When acceptance is communicated.

And there is no cooling-off period in Western Australia. Once you are in a binding contract, you are in it. The only way out is through the conditions written into the contract itself, and if all of those are satisfied, you are committed to settling.

Be honest with yourself about what that means. There is no cooling-off period to fall back on if you get cold feet, and WA has no mandatory vendor statement handed to you before you commit the way some states do. That is not a reason to be nervous. It is a reason to do your homework, ask your questions, and get your advice before you sign, not after. It is a very different world to the eastern states, and we will come back to it.

Why the deposit still matters

Here is something that surprises people. The deposit does not create the contract.The contract is formed when acceptance is communicated. The deposit is then payable under that existing contract, usually within a set number of days. If a buyer fails to pay it on time, they are not tearing up a contract that never existed. They are in breach of one that already does.

That is why, when something goes wrong, one of the first questions a settlement agent or lawyer asks is whether the deposit has been paid. The answer tells them whether the buyer is already in default, whether a notice can be issued, and how much money is sitting in trust.So while the deposit does not form the contract, it does several important jobs:

• It shows the buyer is committed.
• It is held in trust and gives the seller security.
• It forms part of the purchase price at settlement.
• If the buyer defaults, it may be forfeited under the contract.

On that last point, there is a rule worth knowing. A deposit of up to 10 percent is a standard and recognised genuine deposit that a seller can keep if the buyer defaults. Push much beyond that and a court may treat the excess as a penalty and refuse to enforce it. Ten percent is the standard for a reason.

Finance, cash and subject-to-sale offers

One of the most common conditions in a WA contract is finance approval. If finance is included, the contract will usually name the lender or broker, the amount required, and the date by which finance must be approved.

The wording of a finance clause matters more than people think. “Subject to finance” is not a simple phrase. Whether a buyer can walk away, and whether a seller can end the contract, depends on exactly what the clause says and whether the buyer has met their obligations under it.

A cash offer removes that whole layer of risk, which is part of why a clean cash offer can be so attractive to a seller even when it is not the highest number on the table. For more information, please see our ‘Subject to Sale’ guide.

Building and pest inspections are not automatic

This one catches a lot of first home buyers.

A building inspection is not automatically included in a WA contract. Neither is a timber pest inspection. If you want either, you generally need to have a proper condition included before your offer is accepted.

Once the seller has accepted, you cannot simply decide you would now like to add a building inspection or a longer finance period. Any change after that needs both parties to agree. If you want a protection in the contract, ask for it before you sign, not after.

Why the selling agent cannot choose your protections for you

There is a reason your seller’s agent will not build your offer’s protections for you, and it is worth understanding.

I act for the seller. The seller is my client, so I cannot advise a buyer which conditions to include, or design an offer around the buyer’s interests. I can explain what the standard parts of the form do, and I can accurately record the terms a buyer instructs me to put forward. But deciding what legal protections a buyer needs is a matter for the buyer and their own settlement agent or lawyer. While the real estate agent acts strictly for the seller and cannot provide legal or strategic advice to the buyer or design conditions for the buyer’s benefit, the agent remains legally bound to act with honesty, fairness, and accurate disclosure toward all parties.

None of that means I get to play you. I will always be straight with you and I will never mislead you. But I am not your representative in the deal, and you should not expect me to be. That is not a gap in the service. It is the same single-minded representation you would want on your own side the day you are the one selling.

Which is why my best advice to any buyer is simple. If you are in any doubt about a condition, or about anything you are signing, speak to your own settlement agent or solicitor before the offer is written, not after. Once your offer is accepted there is no cooling-off period in Western Australia and no easy way to add a protection you left out. The time to get that advice is before you sign, and the call costs you very little.

What we have to tell you, and what you should ask

People from the eastern states often assume that because WA has no vendor disclosure statement, there is no disclosure here at all. That is wrong, and it is worth understanding properly.

Two duties sit over every sale. Agents must not mislead buyers, and they may be required to disclose known facts that would be material to a buyer’s decision, even where the seller would prefer the information not to be raised. Alongside that sits the Australian Consumer Law, which says we cannot engage in conduct that is misleading or deceptive. The second duty is broader than most people realise.

In WA this is not just general law that applies to everyone. The Code of Conduct that agents work under here spells out that an agent must act honestly and must not engage in conduct that is misleading or deceptive, and that Code is legally enforceable under WA’s real estate regulatory framework. So the duty to be straight with you is written into the rules of my licence, not only into consumer law generally.

Under that law, you do not have to intend to mislead someone to be caught by it. The test is the effect on the buyer, judged by what a reasonable person would take from it, not whether the agent meant any harm. And conduct can mislead by silence or by omission, by leaving something out that creates a false impression, not only by an outright false statement, where the circumstances reasonably called for it to be disclosed.

Here is the kind of thing that catches agents out. A home is advertised as exceptionally quiet, a whisper quiet cul-de-sac with photos of a peaceful backyard, while a nearby source of substantial and regular noise, say a main flight path, is knowingly left out. Depending on the circumstances, advertising the peace while withholding the noise can create a misleading overall impression, and that can expose the agent to a compensation claim from the buyer and to action from the regulator. “It was just a turn of phrase” is not much of a defence, because the test is the impression the advertising created, not what was intended.

Consumer Protection WA gives an even plainer example of the same idea: advertising “beachfront lots” for land that does not actually front the beach. If the words paint a picture the property does not match, that is misleading, no matter how it was meant.

Direct questions work the same way. If a buyer asks me straight out whether a home is under the flight path, I cannot tell them no when the answer is yes. If the seller has told us about an easement on the title, asbestos, an unapproved structure, or something that is not in working order, that gets disclosed in writing too.

A common example is an unapproved structure. Say a previous owner built a granny flat or a large patio without council approval. We disclose in the contract that the structure is unapproved, so the buyer goes in with their eyes open. But disclosure is not the end of it. An unapproved structure can still carry an obligation with the local council that a contract clause does not make disappear. So we disclose it, and we tell the buyer plainly to make their own enquiries with the council and their settlement agent about what it means for them before they commit.

What the law does not do is turn your seller’s agent into your adviser, or ask us to guess at things we do not know. So the responsibility runs both ways. We will declare what we are required to declare, and we will answer your questions honestly. You should ask your questions, all of them, and get your own advice from your settlement agent or solicitor before you sign. Never assume that not asking is the same as there being nothing to find.

How special conditions work

The standard contract covers most ordinary sales. Special conditions deal with everything else, and this is where each transaction becomes unique.

Special conditions can address almost any lawful matter the buyer and seller agree on. But “almost anything” is not “anything.” A special condition still has to be lawful, clear, capable of being carried out, and consistent with the rest of the contract. Careless wording is where disputes are born.

One point that trips up even some agents. The Joint Form of General Conditions applies except where it is varied by the special conditions. That means a special condition can deliberately override a general condition, which is fine when it is done on purpose and clearly. Where a special condition is intended to alter or replace a standard general condition in the Joint Form of General Conditions, the special condition should explicitly state which standard clause is being varied or overridden, to prevent contractual ambiguity. The danger is the accidental contradiction, where it is unclear which clause was meant to win. That is where deals fall over.

A good special condition answers four questions:

• What has to happen?
• Who has to do it?
• By when?
• What happens if it does not?

Get those four right and the condition protects everyone. Get them wrong and it creates the exact fight it was meant to prevent. When a condition is unusual or commercially serious, it is worth having a property lawyer draft or review the wording.

The strangest condition I have ever written

After more than 1,500 sales, you see some unusual requests.

One stands out.A buyer wanted the property to settle at exactly 11:45 in the morning on a particular day, because in her belief that was the moment the moon and stars aligned and the home would bring her peace. Normally that might sound far fetched. But contracts are not there to judge why people want things. They are there to document what has been agreed.

The seller was happy to accommodate it. The risk was obvious though. If the buyer did anything to delay settlement, by their own actions, the exact time could be missed. So we tied the deposit directly to the settlement timing obligation. Both parties agreed that if the buyer caused settlement not to occur as agreed, the deposit was at risk. It was a standard ten percent deposit and a cash purchase with no finance involved, so the chance of an outside delay was very low.The property settled exactly as agreed. The lesson is not that unusual conditions are a good idea. It is that a condition does not have to be common. It has to be clear, and for anything this specific, drafted with care and ideally a lawyer’s eye. It is worth being plain about the risk, too. Specifying a settlement time down to the exact minute creates real practical and legal risk under modern electronic conveyancing, where administrative and banking delays of minutes or hours are common. Trying to trigger an automatic forfeiture of a 10 percent deposit over a minor timing delay is vulnerable to challenge as an unenforceable penalty, particularly since standard contract terms require default notices and cure periods before termination.

Why more conditions usually means a weaker offer

Buyers often assume that adding conditions makes their offer safer, and therefore stronger. Usually the opposite is true.

Every extra condition is another way the contract can fall over, and sellers know it. Imagine two offers at the same price:

• Offer A: finance, building inspection, timber pest inspection, subject to the sale of another property, and an extended settlement.
• Offer B: finance only.

All other things being reasonably equal, most sellers will take Offer B. Not because the price is better, but because there are fewer ways for it to collapse.

That does not mean strip out protections you actually need. It means every condition should earn its place. A seller comparing offers is not only weighing the price. They are weighing finance risk, inspection risk, settlement timing, the size of the deposit, and how many ways the buyer could walk. The cleanest offer often wins, even when it is not the highest.

A warning most sellers never hear

Here is one that has caught good people out over the years.

If you are selling in order to buy your next home, and you need finance to buy that next place, sort your finance out and get your approval in hand before you sign a contract to sell.

I have seen sellers accept an offer, then discover they cannot get the finance to buy their onward property, and try to pull out. Unfortunately the contract does not work that way. As long as the buyer keeps meeting their obligations through to settlement, the seller cannot terminate simply because their own next purchase has fallen through. The finance clause protects the buyer. There is no equivalent escape hatch for a seller who has not sorted their own funding.

Accepting an offer is a commitment. Make sure your side of the puzzle is in place before you make it.

This touches on financial matters. Speak to your bank, broker or financial adviser about your own situation before you commit.

How WA compares to the rest of Australia

The table below is a general guide to a typical residential private-treaty sale in each state and territory. Processes vary within each jurisdiction, so treat it as a starting picture, not a rule for your own transaction. The biggest practical differences are when a contract becomes binding, whether there is a cooling-off period, and how much disclosure and legal preparation happens before you sign.

Cooling-off figures below were current as at July 2026. These rules change, so check the current position for your state before relying on them.

State or territory	Who typically prepares the contract	Cooling-off period (private treaty)	Who typically handles settlement
Western Australia	Real estate agent (standard O and A)	None, unless the parties insert one	Licensed settlement agent or lawyer
New South Wales	Solicitor or conveyancer, before marketing	5 business days	Solicitor or conveyancer
Victoria	Solicitor or conveyancer (with a section 32 statement)	3 clear business days	Solicitor or conveyancer
Queensland	Agent completes a standard contract; solicitor-led conveyancing	5 business days	Solicitor (conveyancers less common)
South Australia	Conveyancer or solicitor (with a Form 1 statement)	2 clear business days	Conveyancer or solicitor
Australian Capital Territory	Seller’s contract pack prepared before sale	5 business days	Solicitor or conveyancer
Northern Territory	Agent, conveyancer or solicitor (approved form)	4 business days, unless waived, reduced or extended by agreement	Conveyancer or solicitor
Tasmania	Property agent or legal representative	No general statutory cooling-off period identified for ordinary private-treaty sales; check the contract terms	Conveyancer or solicitor

Two things stand out from that table for anyone used to the eastern states.

First, cooling-off. Most eastern jurisdictions give a buyer a few days to change their mind after signing a private treaty sale. WA does not. Here, once your offer is accepted and acceptance is communicated, you are bound.

Second, and this is the part people rarely connect, that lack of cooling-off is part of what makes auctions attractive over east. In states where private-treaty buyers ordinarily receive cooling-off rights, those rights generally do not apply at auction. An auction therefore gives the seller an unconditional contract with no cooling-off period once the property is knocked down to the successful bidder. That is one practical attraction of auctions in those markets, alongside others like market culture, competition and local pricing customs. WA already provides no general statutory cooling-off period on an ordinary private-treaty contract, so we reach that same certainty without needing an auction to get it, although auction and private-treaty sales still differ in other ways.

Disclosure is the other divide. Victoria has its section 32 statement, South Australia it’s Form 1, and Queensland now has a mandatory seller disclosure regime. WA has no universal vendor disclosure statement of that kind. As covered earlier, sellers and agents here still have a real duty to disclose known material facts and to avoid misleading conduct, but the process carries less compulsory paperwork before signing.

This catches people from interstate, and it catches people from overseas even more. If you have bought a home in England, the United States, or anywhere else, the process there almost certainly worked differently again. Different contract, different protections, different timing. That is the point worth holding onto. Whatever you are used to, at home or interstate, do not assume it carries over here. Western Australia has its own way of doing things, and the smartest thing any buyer from outside the state can do is treat the WA process as new, ask how it works, and get local advice before signing rather than after. That is not a criticism of how it is done anywhere else. It is simply the reality of buying here.

Final thoughts

The Offer and Acceptance contract is far more than paperwork. It records the agreement between buyer and seller. Every figure, every date, every condition, every obligation.

In Western Australia, that agreement becomes binding the moment acceptance is communicated, with no cooling-off period to fall back on. That makes understanding the contract before signing especially important in WA.

After more than two decades and more than 1,500 sales, I can tell you that most contract problems do not happen because someone was dishonest. They happen because someone did not fully understand what they were agreeing to before they signed.

If you are buying or selling in the Perth Hills and you would like someone to walk you through the process in plain English before you sign anything, get in touch. Happy to help.
