Real Estate Agent Laws Every Home Buyer in Australia Should Know
Before you make an offer on your next property, understand the legal obligations every real estate agent must follow — and how to use them to your advantage.
Real estate is one of the most heavily regulated industries in Australia, yet most home buyers go into negotiations without knowing the full extent of the rules that govern the agents they deal with. Understanding those rules before you start inspecting properties can save you genuine stress — and potentially tens of thousands of dollars.
Agents Face More Scrutiny Than You Might Expect
As Property Update reports, real estate agents can be secretly monitored by Fair Trading inspectors at auctions, face disciplinary proceedings at civil and administrative tribunals such as NCAT in New South Wales, VCAT in Victoria, and QCAT in Queensland, and receive fines from state Consumer Affairs bodies for conduct such as underquoting or misleading advertising under the Australian Consumer Law. They can also be reviewed by their state's Real Estate Institute over professional conduct matters.
Agents who cross the line tend to get caught, and regulators have strong public interest incentives to make examples of misconduct. The practical outcome is that most agents are operating carefully within the rules — which means, once you know those rules, you can use them to your advantage.
One obligation that catches buyers off guard: agents are legally required to present every offer to the seller right up until the contract of sale has been finalised, unless the seller has specifically instructed the agent not to submit offers below a particular figure. If you put an offer in writing, it must go to the seller.
What Agents Must — and Cannot — Tell You
Agents also have a duty to buyers, not just to the seller who hired them. Under Australian Consumer Law, if an agent knows something about a property that a reasonable buyer would want to know and that the buyer could not otherwise find out, the agent cannot conceal or suppress that information.
That obligation covers a wider range of disclosures than many buyers expect. Council approvals and disputes, body corporate issues, the history of the property — including whether a serious incident such as a murder or suicide has taken place there — all fall within the scope of what must be disclosed if the agent is aware.
Importantly, this obligation covers what the agent knows. It does not remove your responsibility to conduct your own due diligence. Building and pest inspections, strata report reviews, and having a solicitor review the contract remain yours to arrange.
Having a clear sense of your borrowing capacity before you start inspecting also matters here — when you know your limits with confidence, you are less likely to be pushed into a purchase that does not fit your financial position.
Gazumping Is Legal — But You Can Reduce Your Risk
Gazumping occurs when you have reached a verbal agreement with the agent or vendor to buy a property at an agreed price, only for the seller to then accept a higher offer from another buyer before contracts are exchanged. This is legal across all Australian states and territories.
The sale is not binding until both parties have signed and exchanged contracts. Writing a deposit cheque does not secure the property. Nothing is locked in until the contract is signed and dated by both parties.
To reduce your risk, make your offer as attractive as possible — price matters, but flexible settlement terms or a rent-back arrangement for the seller can carry real weight too. If you are told there is a competing offer, Fair Trading NSW recommends asking for confirmation of that in writing. More usefully, ask whether the competing offer is backed by a signed contract of sale. If it is not, you may be competing against a verbal proposal — or nothing at all.
It is also worth being alert to what is known as a Dutch auction, where an agent privately negotiates with multiple buyers and keeps feeding each one information about the others' offers to push them into outbidding each other. Pressing the agent on whether a competing offer is under a signed contract is a direct way to test whether you are in that situation.
Why Your Finance Position Changes Everything
The clearest advantage you can give yourself in any property negotiation is having your finance sorted before you start making offers. Pre-approval gives you certainty about your spending limit, lets you move quickly when the right property comes up, and signals to the vendor that you are a serious buyer.
Whether you are a first home buyer still working out how much you might be able to borrow, or an existing owner looking to upgrade or refinance, understanding your financial position before you start dealing with agents puts you in a far stronger negotiating position.

Understanding the rules agents must follow does not just protect you — it makes you a more confident and better-prepared buyer.
