What Is Flood Disclosure in Queensland Real Estate? Definition and Agent Guide

Your seller has just accepted an offer on a Rocklea home. The buyer’s solicitor is reviewing the Form 2. You know the property backs onto a drainage easement and the suburb sits within a Brisbane City Council flood overlay. Here is the question every agent working in flood-affected Queensland needs to be able to answer with confidence: what are the actual flood disclosure obligations in this state — and exactly where does your professional exposure sit?

Flood disclosure in Queensland real estate refers to the obligations on sellers, and the agents who act for them, to communicate information about a property’s flood risk, flood history, and flood overlay status to prospective buyers. The mechanics of this obligation are more nuanced than most agents realise, and the gap between what the new statutory seller disclosure scheme mandates and what common law and the Australian Consumer Law require is where professional risk quietly accumulates.

How Flood Disclosure Works in Queensland Real Estate

The Seller Disclosure Regime from 1 August 2025

The Property Law Act 2023 (Qld) came into effect on 1 August 2025, introducing one of the most significant overhauls of Queensland’s property laws in decades, including the establishment of a comprehensive seller disclosure regime designed to modernise property transactions and enhance transparency for buyers.

Under this regime, a seller must provide a buyer with a completed and signed Form 2 Seller Disclosure Statement and all prescribed certificates relevant to the property before the buyer signs a contract. These documents must be accurate and up to date at the time they are given to the buyer. The regime applies to all contracts entered into on or after 1 August 2025, regardless of when the property was listed for sale.

This is the framework. Now here is the critical detail that every Queensland agent must internalise: flood history and flood overlay information are not mandatory disclosures under the Form 2 Seller Disclosure Statement.

What the Form 2 Does — and Does Not — Require on Flooding

One significant omission from the mandatory disclosure list is flooding information. Despite Queensland’s well-documented flood history and the financial and safety risks associated with flood-prone properties, there is currently no requirement for sellers to disclose whether a property has previously experienced flooding or is located within a designated flood zone.

The disclosure regime does not require sellers to reveal everything. The REIQ explains that the disclosure statement does not cover flooding or natural hazard history, structural soundness or pest infestation, building or development approvals, asbestos presence, and utility connections. The Form 2 is comprehensive across title, encumbrances, planning notices, and body corporate matters — but flooding sits expressly outside its mandatory scope.

Buyers should be aware that the disclosure statement does not cover everything. Buyers are encouraged to conduct their own due diligence, including building and pest inspections, flood searches, planning checks and searches on any other relevant matters. The REIQ makes this explicit in its guidance to the industry: flood risk remains a buyer-initiated inquiry.

Where Flood Information Comes From in Queensland

FloodCheck gives access to historic flood information and data developed as part of the Queensland Flood Mapping Program. However, agents and buyers need to understand the limitations of this tool. FloodCheck should not be used to determine the potential for flooding at the property level. The purpose of FloodCheck is to provide information on the existence of flood studies over properties. The existence of a flood study over any property does not indicate any potential for flood risk. To determine potential flood risk at the property level, contact the relevant local government who is responsible for information at the property level.

The Queensland Floodplain Assessment Overlay (QFAO) map layer identifies potential floodplains that may be at risk of inundation from riverine flooding, but it is not intended to predict riverine flooding for specific land parcels. For property-level flood risk, the relevant council’s planning scheme overlays are the authoritative source. Councils identify flood-affected land using historical data and hydraulic modelling based on the Annual Exceedance Probability (AEP) of different flood events. This represents the statistical likelihood of flooding occurring in any given year. For example, Brisbane City Council classifies flooding as high likelihood at 5% AEP, medium likelihood at 1% AEP, low likelihood at 0.2% AEP, and very low likelihood at 0.05% AEP. These categories are incorporated into planning schemes through flood and overland flow overlays, which guide how land can be used and developed.

Why Flood Disclosure Matters for Queensland Agents

The Gap Between Mandatory and Necessary

The fact that flooding is not a mandatory Form 2 disclosure does not mean agents can treat it as irrelevant. The two obligations operate on completely different tracks, and confusing them is where agents get into trouble.

Interestingly, there is currently no obligation to disclose any history of flooding related to the property, which is surprising given the potential impact a flood event could have on a buyer. That observation from a legal commentary reflects genuine industry unease — and the professional risk for agents flows directly from it. A buyer who later discovers their property sits in a high-AEP flood zone, or that it was inundated in 2011, will ask one question first: did the agent know?

Under the Australian Consumer Law (ACL), both vendors and agents are legally required to disclose known information or material facts that are crucial to a buyer when deciding whether or not to purchase a property. That means it is considered a legal offence to omit information, mislead or deceive parties to a contract. Non-disclosure can lead to termination of contract, fines, or a potential lawsuit.

The ACL operates independently of the Property Law Act 2023 regime. Where a seller or agent possesses knowledge of flood history and fails to disclose it, that omission can constitute misleading conduct under the Competition and Consumer Act 2010 (Cth), regardless of whether that information was technically required in Form 2.

Financial and Market Consequences for Buyers

A hidden cost associated with flood zones is insurance. Properties within mapped flood areas often face higher premiums or limited availability of cover, which can in turn affect finance approvals and resale value. Lenders are also alert to flood risk, and most mortgage covenants require borrowers to maintain adequate insurance and comply with all planning controls. Where insurance is unavailable or restricted, or where a property sits within a flood hazard overlay, this can create difficulties in meeting those obligations and may impact the lender’s willingness to advance funds.

These are material considerations. A buyer who cannot obtain flood insurance at a viable premium — or who discovers post-contract that planned development is constrained by a flood overlay — has a legitimate grievance. Depending on the identified level of risk, overlays may dictate minimum floor levels, require flood-resilient materials, or, in some cases, prevent new building work altogether. For a buyer with development intentions, this is potentially deal-ending information.

Brisbane’s 2025 update added thousands of properties to higher flood-risk categories, while improved modelling removed others. The Sunshine Coast has refined its overland flow mapping to better reflect the intensity of modern rainfall events and the influence of climate change. Flood mapping is not static, and what was accurate at listing may have shifted by the time a buyer conducts their own search.

The Ongoing Legislative Debate

This exclusion has been the subject of ongoing public and industry debate. Critics argue that buyers should not be expected to independently source flood data — often from multiple, inconsistent sources — and that this information should be a core part of the seller’s legal obligations. As climate risks increase, it is likely this issue will remain a contentious topic in property law reform discussions.

Queensland agents operating in flood-exposed markets — Brisbane’s western suburbs, Ipswich, the Lockyer Valley, Townsville, Cairns, and many parts of the Darling Downs — should expect that legislative reform may eventually bring flood disclosure into the mandatory Form 2 framework. The current position reflects the state the law is in now, not necessarily where it will be.

The Legal Exposure Framework: What the Law Actually Requires

Section 99 and Section 104 of the Property Law Act 2023

Significant consequences may arise if a seller fails to comply with the disclosure obligations under section 99 of the Property Law Act 2023 (PLA). Under section 104 of the PLA, the buyer may terminate a contract any time before settlement of the contract, by giving written notice to the seller terminating the contract, if the seller fails to give the buyer a Form 2 for, or prescribed certificate applicable to, the property before the contract of sale is signed by the buyer.

Critically, the termination right also applies where the Form 2 contains inaccurate or incomplete information. Generally, a buyer may terminate a contract at any time before settlement if a seller provides a disclosure statement or a prescribed certificate that is inaccurate or incomplete in relation to a material matter affecting the property, the buyer was unaware of the true state of affairs at the time they signed the contract, and if the buyer had known, they would not have proceeded to sign the contract.

If the contract is terminated, the buyer is entitled to a full refund of all money paid, including any interest accrued on that amount. The legislation leaves the term ‘material matter’ open for interpretation, with the exception that it excludes information relating to the property’s council and water rates. Given the consumer protection focus of the new regime, it is anticipated that courts will take a buyer-friendly approach when interpreting these provisions.

Where Flood Information Could Become a “Material Matter”

Although flood history is not a mandatory Form 2 disclosure, an agent’s conduct around flood-related information can still generate liability under a separate but overlapping framework. Failure to provide accurate information with the disclosure statement amounts to a misrepresentation or misleading and deceptive conduct, giving the buyer a right to compensation or other remedies at common law or under the Australian Consumer Law.

Consider a scenario: an agent is aware — through prior conversations with the seller, through their own knowledge of the area, or through a council planning certificate — that the property experienced significant inundation in the 2011 Brisbane floods. If that agent makes representations in marketing materials about the property’s suitability as an investment, or its location in a “low-risk” precinct, and fails to disclose the flood history, the ACL exposure is real and independent of what Form 2 requires.

Sellers are not required to disclose flooding information unless providing misleading information. Buyers should conduct their own enquiries, especially in flood-prone areas. That framing — “unless providing misleading information” — is the hinge. The Form 2 does not require proactive flood disclosure, but it does not immunise against misleading conduct where flood-related knowledge is withheld.

The Agent’s Role in Preparing the Form 2

If an agent is preparing the Form 2, they must have written instructions from the seller and follow a strict workflow. Agents are not permitted to provide legal advice or interpret search results. This is a bright line. Agents who prepare the Form 2 on behalf of sellers — which the REIQ’s Seller Disclosure Tool facilitates — must understand the boundaries of that role. Flagging to a seller that council flood mapping exists, and directing them to seek legal advice before making representations, is well within scope. Interpreting what that mapping means for disclosure purposes is not.

The REIQ has launched the Seller Disclosure Tool in Realworks — a purpose-built solution to help residential and commercial agents prepare the Form 2 Disclosure Statement on behalf of their clients. The Seller Disclosure Tool offers two flexible options to suit your workflow, including a self-complete option from $99, which centralises documentation, automates key tasks, and pulls in relevant property data — helping agents save time, reduce risk and remain compliant.

What Queensland Agents Need to Know About Flood Disclosure

Building a Consistent Flood Due Diligence Practice

Every Queensland agent working in a region with known flood exposure — which, given the state’s geography, means most agents — should have a consistent internal practice for handling flood information. This is not about legal compliance alone. It is about professional integrity and protecting your sellers from post-contract disputes that derail settlements.

Before listing a property, agents should obtain and review the relevant council planning scheme flood overlay data. The FloodCheck interactive map provides access to flood mapping products and data developed to improve understanding of flood behaviour on a regional scale, including historic floodlines (in years 1893, 1974, 2010 and 2011) and the likely extent of floodplains, as well as technical reports and flood studies including the broadscale Queensland Floodplain Assessment Overlay. For property-level accuracy, however, agents should direct sellers and buyers directly to the relevant local council, whose planning scheme overlays carry the authoritative data.

Over the past year, councils and state agencies have updated their flood mapping and modelling. Properties that once appeared safe may now fall within a flood overlay or overland flow path. Agents who relied on searches conducted months earlier — or who assumed a suburb’s historical flood-free status still holds — are operating on potentially stale information.

What Agents Should Tell Sellers

When taking a listing, agents should inform sellers clearly that the Form 2 does not currently require flood disclosure, but that existing knowledge of flood history cannot be used to mislead buyers. Sellers who are aware their property experienced inundation — whether in 2011, 2022, or at any other time — need to understand that volunteering this information, or ensuring it is available through the due diligence process, reduces their legal exposure rather than creating it. A buyer who discovers flood history after settlement and can demonstrate the seller knew is in a far stronger position to pursue a remedy.

Direct sellers to their solicitor or conveyancer for advice on whether specific flood information they hold ought to be disclosed. That is not a conversation agents should be having on their own. What agents should be doing is creating the conditions for that conversation to happen early — before the Form 2 is signed, before marketing begins, and well before a buyer’s solicitor starts asking questions.

What Agents Should Tell Buyers

Buyers should continue due diligence — building inspections, pest reports, and flood searches are still recommended regardless of what the Form 2 contains. Queensland agents working with buyers — particularly those from interstate or overseas who may not understand the state’s flood geography or the current disclosure framework — have a professional responsibility to communicate this plainly. The Form 2 is a starting point for due diligence, not the end of it.

Buyers should carefully review the Form 2 and all attachments. Buyers are encouraged to conduct their own due diligence, including building and pest inspections, flood searches, planning checks and searches on any other relevant matters.

For buyers in flood-exposed areas, a specific flood search through council — separate to FloodCheck, which is regional in scope — and a review of the relevant planning scheme overlay should be treated as non-negotiable due diligence steps, not optional extras.

Auction Sales and the Timing Obligation

For auction sales, sellers must give the disclosure to registered bidders before the auction starts. This timing requirement is absolute, and the absence of a cooling-off period for auction contracts makes it more consequential. Where flood overlay information is relevant to bidders’ assessments — and in many Queensland markets it is — agents preparing auction campaigns should factor in the lead time required to obtain council flood certificates and ensure all registered bidders have access to any relevant flood data that, while not mandated by Form 2, may be material to a bidder’s decision.

What This Means for Queensland Agents

The current position on flood disclosure in Queensland real estate is one of layered obligation. Since 1 August 2025, sellers must provide comprehensive disclosure documents to buyers before they sign the contract — a fundamental shift from the traditional “buyer beware” approach. But flooding remains conspicuously absent from the mandatory disclosure list, creating a zone of professional risk that agents must navigate with care.

The practical takeaway operates on three levels. First, know the Form 2 accurately: flooding is not a prescribed disclosure under the Property Law Act 2023, and you should not represent it as such to sellers or buyers. Second, know where your ACL exposure sits: if you have knowledge of flood history or flood overlay status and you make representations — or remain strategically silent — in circumstances where a reasonable buyer would consider that information material, you face real liability independent of what Form 2 requires. Third, direct every party to appropriate professional advice: sellers to their solicitors on disclosure strategy, buyers to council flood search tools and their own conveyancers before signing.

As climate risks increase, it is likely this issue will remain a contentious topic in property law reform discussions. Queensland agents who build sound flood due diligence practices now — standard council flood searches for listings in exposed areas, clear buyer guidance documentation, and consistent seller conversations about the limits of Form 2 — will be positioned ahead of the curve when legislative reform eventually arrives, and protected against claims in the meantime.

Flood disclosure in Queensland is not just a legal technicality. It is one of the defining professional obligations of operating in one of the most flood-exposed property markets in the country.
