Queensland Auction Law Changes: What Every Agent and Auctioneer Needs to Know in 2026
Your vendor wants to know what the property might sell for. Your buyer asks if there’s a reserve. Your bidder registration form is sitting on the table ten minutes before the hammer drops. If any part of that scenario makes you pause, the compliance landscape for Queensland auction law in 2026 deserves your full attention.
In Queensland, the conduct of property auctions is regulated under the Property Occupations Act 2014 (Qld) and its supporting regulations — legislation designed to protect consumers and applied to property agents, resident letting agents, auctioneers, and their employees. That framework remains the primary regulatory instrument in 2026, but it now operates alongside a sweeping overhaul to broader property law that directly reshapes how auction campaigns are prepared and how disclosure obligations are met before a single bid is called.
The Property Law Act 2023 (Qld) was proclaimed and commenced on 1 August 2025, representing the most comprehensive set of changes to Queensland’s property laws in approximately 50 years. For agents and auctioneers, that commencement date is not a background legal footnote — it is an operational line in the sand that changed pre-auction workflows for every residential and commercial campaign in the state.
The Regulatory Framework: Two Acts, One Campaign
Understanding Queensland auction law in 2026 means holding two pieces of legislation in mind simultaneously. They serve different functions but interact at every stage of the auction process.
The Property Occupations Act 2014 (Qld) (the POA) regulates the conduct of property auctions, applying to property agents, resident letting agents, auctioneers, and their employees. It governs who may conduct an auction, how bidder registration must be handled, how vendor bids must be disclosed, what an auctioneer may or may not say about price, and the licence requirements separating an auctioneer’s role from a general real estate agent’s role. These provisions have not changed in their fundamental structure since the POA replaced the old Property Agents and Motor Dealers Act 2000 (PAMDA), but regulatory enforcement expectations have sharpened considerably.
The Property Law Act 2023 (Qld), which came into effect on 1 August 2025, replaces the Property Law Act 1974 and introduces a new legal framework for real estate transactions, modernising conveyancing, creating greater transparency, and imposing new responsibilities on both sellers and buyers. Its most consequential change for auction practitioners is the mandatory seller disclosure scheme, which now expressly applies to sales by auction.
The seller disclosure scheme applies to the sale of freehold land, including auctions, mortgagee or receiver sales, and sales resulting from the exercise of an option — subject to specified exceptions. For agents managing auction campaigns, this means the pre-auction period now carries disclosure obligations that did not previously exist in statutory form. The old caveat emptor framework that once placed the burden of investigation almost entirely on buyers has been substantially displaced.
The Price Guide Prohibition: Still Absolute, Still Enforced
The prohibition on price guides for auction properties is among the most misunderstood obligations in Queensland real estate. Agents who have worked in Victoria or New South Wales — where statutory price guide systems exist — sometimes bring assumptions that do not apply here.
Under the Property Occupations Act 2014, a real estate agent is prohibited from giving any type of price guide to potential buyers when a property is going to auction in Queensland. This is not a prohibition on misleading price guides. It is a prohibition on price guides entirely, in any form, written or verbal, formal or casual. A real estate agent must not distribute misleading price guides in marketing and advertising material, or through written or verbal communication with prospective buyers — and in practice, this means an agent must not give a price guide that is less than the asking price, less than the reserve price at auction, or less than the likely sale price of the property. But the Queensland position goes further: for auction properties, no estimate is permissible at all.
The rationale is worth understanding because it explains why the prohibition has survived lobbying from some industry quarters. As an agent cannot know how high the final bid will be, it is misleading to give a price guide — and providing one prevents agents from artificially heating up an auction by drawing in bidders who have no realistic prospect of being the successful purchaser. The policy is market integrity, not bureaucratic caution.
The penalty exposure is significant. A breach of Australian Consumer Law can be punished by a penalty for an individual of up to $500,000 per offence. An agency is liable for a fine of either $10 million or three times the value of the accrued benefit — or, if no benefit can be calculated, 10% of the agency’s previous annual turnover. These are not theoretical figures. The Office of Fair Trading actively monitors auction marketing campaigns, and the evidentiary standard matters: underquoting can be difficult to prove because the disparity between an estimate and sale price can be attributed to market demand or vendor change of mind, making written evidence of the misleading pricing necessary to sustain a complaint.
The contrast with other jurisdictions is stark. Victoria will soon require auction reserve prices to be published at least a week before auction day under new laws to be introduced in 2026, with the reform aimed at curbing underquoting and giving buyers more transparency. Queensland’s approach is architecturally different: rather than mandating price disclosure, it prohibits it entirely for auction properties, allowing the market to set value through competition. Agents advising interstate investors or interstate buyers attending Queensland auctions must make this distinction explicit.
In practical terms: do not quote a range. Do not say “the vendor is expecting mid-sevens.” Do not let a DM from a buyer’s advocate asking “what’s the reserve?” go unanswered with anything other than a lawful deflection. Your social media presence, your email threads, and your verbal conversations are all within scope.
Vendor Bid Disclosure: What the Law Actually Requires
Queensland permits vendor bids at auction — but only within a controlled framework that demands transparency before bidding commences. The seller may bid, either personally or by a representative. What they cannot do is engage in dummy bidding, which is categorically different.
A dummy bid involves increasing bidding at an auction by the seller, a family member or friend, or any other individual who is not a serious buyer. Unlike vendor bids, dummy bids are illegal in Queensland and across Australia, and should be reported because they artificially inflate a property’s price at auction.
The Property Occupations Act 2014 now contains a dedicated provision — inserted by the Property Law Act 2023 — at section 229A dealing with the disclosure of a seller’s right to bid at auction. The auctioneer is required to disclose to prospective bidders, before the auction commences, that the vendor or their representative may submit bids. This disclosure obligation exists precisely to ensure that participating bidders understand the bidding environment they are entering. An auctioneer who fails to make this disclosure before the event, or who accepts vendor bids without having made the disclosure, faces regulatory exposure under the POA.
When a vendor bid is made, the auctioneer must announce it clearly as a vendor bid at the time it is made. The bid must be distinguished from genuine bidder competition. Failing to announce vendor bids as such is not a minor procedural lapse — it is conduct that actively misleads participants about the state of competition on the floor. While a bid accepted in breach of registration requirements can be treated as binding between buyer and seller, this does not shield the auctioneer from regulatory consequences. The same principle applies to vendor bid disclosure failures.
Practically, auctioneers should embed vendor bid disclosure into their standard auction preamble — the structured address delivered before bidding opens. The REIQ’s best practice guidelines, updated as at early 2026, address this in their auction conduct recommendations. Before bidding begins, the auctioneer must ensure that their name is displayed prominently at the auction site and/or announced, and must display and announce the conditions of the auction, including the auction process, the deposit payable, all other pertinent terms of the contract of sale, and any other information material to potential bidders.
Bidder Registration Requirements: No Registration, No Bid
Queensland’s mandatory bidder registration scheme is among the most operationally consequential compliance obligations in the auction process. It is not optional, and it is not satisfied by an informal sign-in sheet.
Before an auction starts, everyone who wants to bid must register by giving the auctioneer their name, address, and proof of identity such as a driver’s licence or passport. Each registered bidder receives a numbered card, and only people with these cards can make bids. The auctioneer is required to maintain the register in accordance with Queensland Government regulations. The auctioneer is required to keep a register of all bidders at the auction in accordance with Queensland Government regulations, and bids will only be accepted from registered bidders.
The registration obligation extends to bidders acting as representatives. Any person bidding on behalf of another person must provide the auctioneer with a copy of their written authority before the auction, otherwise the bidder will be taken to be acting on their own behalf. This matters for corporate buyers, trustees, and buyers’ agents — all common in the Queensland market. If a buyers’ agent holds up a paddle without having lodged written authority, they bid in their own name. The consequences — including deposit liability and potential contract complications — fall on them personally unless the sale is quickly unwound.
Failure to comply with bidder registration and record-keeping obligations can result in serious consequences for auctioneers including monetary penalties, disciplinary action, suspension or cancellation of the auctioneer’s licence, and regulatory enforcement action.
The post-hammer scenario also requires attention. A situation occasionally encountered in practice is where a successful bidder advises — after the fall of the hammer — that they were bidding on behalf of another person. In Queensland, non-disclosure by a bidder that they are not the prospective buyer does not automatically invalidate the sale. The contract may still proceed in the name of the undisclosed person. However, if the bidder’s representative capacity was disclosed but not recorded at registration, the auctioneer may be exposed to regulatory action for failing to comply with bidder record requirements. Document everything. The register is your audit trail.
The New Seller Disclosure Obligation for Auctions
This is the change that has most significantly reshaped auction campaign workflows since 1 August 2025. The mandatory seller disclosure scheme under the Property Law Act 2023 now applies to auction sales, and it changes what must happen before the first bid is called.
One of the important reforms Queensland’s new Property Law Act 2023 introduces is a new mandatory seller disclosure scheme, under which anyone selling residential or commercial property or vacant land in Queensland is required to disclose specific information to a prospective buyer before the buyer enters into a contract. For auction sales, a contract is formed at the fall of the hammer — which means disclosure must be provided to registered bidders before the auction commences.
In auctions, a buyer is legally bound as soon as the sale is confirmed. Now, before an auction, sellers must give all disclosure documents to every registered bidder. The Property Law Act 2023 also makes a specific provision for late registrants: for a buyer registered as a bidder before the start of the auction, disclosure documents must be given to the buyer before the start of the auction; and for a buyer registered as a bidder after the start of the auction who was not given the documents before the start of the auction, the auctioneer must comply with the requirements of section 103 — for example, by displaying the disclosure documents at the auction.
The disclosure statement itself must be in the approved form and contain prescribed information. Before a buyer signs a contract of sale, the seller must provide a signed disclosure statement containing prescribed information in the approved form. The practical implication for agents is that the disclosure package — including certificates required for community title properties — needs to be assembled and distributed as part of the auction campaign preparation, not as an afterthought before the hammer drops.
The new disclosure regime significantly strengthens buyer protection. Buyers can now terminate a contract before settlement if the seller fails to provide disclosure documents before signing, the documents are inaccurate or incomplete or misleading, or if material facts are withheld that would have influenced the decision to purchase. For agents, this is the key operational risk: an undisclosed or inaccurately disclosed matter discovered post-auction creates a termination right that can unwind what appeared to be a clean sale.
Post-Auction Private Treaty: The 48-Hour Rule
When a property passes in at auction, the clock starts immediately. Queensland’s post-auction private treaty window is tight, and agents who misunderstand it expose their vendor clients to deals that unexpectedly include a cooling-off period.
The cooling-off period does not apply to contracts formed on a sale by auction. In addition, the Property Occupations Act 2014 provides that a cooling-off period will not apply to contracts entered into within two clear business days following an auction with a registered bidder for the auction.
The precision of this rule matters. No cooling-off period applies to a contract entered into no later than 5:00 pm on the second clear business day after the property was passed in at auction with a registered bidder for the auction. The bidder must have been registered at that auction — buyers who simply attended without registering do not qualify for the exemption. This is a common source of error: agents sometimes assume any person they spoke to at or near an auction is treated as a registered bidder for the purposes of the exemption. They are not.
Buyers who make pre-auction offers also waive their cooling-off period if the offer is accepted less than 72 hours before the scheduled auction. This creates a third scenario — the pre-auction sale — that deserves its own process discipline. Document the time of acceptance, not just the date. A verbal acceptance that cannot be timed may be difficult to rely upon if the buyer later claims the 72-hour window was not triggered.
For agents working post-auction negotiations, the practical discipline is to get a signed contract from a registered bidder before 5:00 pm on the second clear business day, to advise the vendor that the cooling-off-free window closes at that time, and to communicate clearly to the prospective buyer that conditions on the contract are generally not appropriate within the post-auction window where the parties are seeking a clean, unconditional result.
Auctioneer Licensing: A Distinct Obligation
It bears stating clearly because it is regularly misunderstood by agents transferring from other states: in Queensland, conducting a real estate auction requires an auctioneer’s licence — not merely a real estate agent’s licence.
An auctioneer is specifically defined as a person who holds an auctioneer licence. An auctioneer licence is separate and distinct from a real estate agent licence, and it authorises the auctioneer, in the course of business or as an employee, to sell or attempt to sell or offer for sale any real property or interest in real property by way of auction as an agent for others for reward, and to sell the property by any means during the auction period.
The authority the auctioneer holds at the point of sale is significant. At the fall of the hammer, a binding contract is formed. At that point, the auctioneer has authority to sign the contract of sale on behalf of both the seller and the successful bidder. This authority arises automatically from the auction process and cannot be withdrawn by either party once the hammer has fallen. That is a substantial authority — and one that justifies the separate licensing pathway.
Agents who wish to call auctions must hold an auctioneer’s licence issued under the POA. Agencies that regularly run auction campaigns under the hammer should satisfy themselves that every person calling bids is properly licensed. The liability that attaches to an unlicensed person calling an auction falls squarely on the agency.
What This Means for Queensland Agents
The Queensland auction law changes in 2026 are not abstract compliance updates. They affect what your campaign checklist looks like, what you say on the phone to a buyer’s agent, and what paperwork must be assembled before auction day.
On the price guide prohibition: maintain zero tolerance. The prohibition on price guides for auction properties is complete. No ranges, no hints, no “what the vendor has in mind.” If buyers — particularly those from interstate or overseas — ask for guidance, explain the Queensland framework and direct them to conduct their own due diligence through comparable sales data. That is a service, not a deflection.
On vendor bid disclosure: embed the disclosure statement into your auction preamble as a standing practice. Announce that the vendor may bid before any bid is called. If a vendor bid is made, call it clearly and distinctly. Document it in the bidder register.
On the seller disclosure scheme: treat the disclosure package as part of your listing preparation, not your pre-auction checklist. Assemble the disclosure statement and all required certificates when you take the listing. For community title properties, allow adequate lead time to obtain body corporate certificates. Distribute documents to all registered bidders before the auction commences. For late registrants, have a displayed copy available at the auction venue.
On bidder registration: arrive at every auction with a compliant registration system in place. Verify identity. Record representatives’ written authority before the auction begins. Retain your register — it is an audit document.
On post-auction private treaty: advise your vendor immediately when a property passes in. Identify which registered bidders remain in play. Work within the two-clear-business-day window and document the time of any accepted offer. Know that a buyer who was not a registered bidder at the auction does not qualify for the cooling-off exemption.
The compliance burden in this environment is real, but it is also manageable with the right systems. Agents who treat auction compliance as operational discipline — rather than legal risk-avoidance — build the kind of professional reputation that earns repeat listings and withstands regulatory scrutiny. The framework exists to protect buyers. Working within it well is how you protect your licence, your agency, and your vendor’s result.
