Evidence QCAT Accepts in Queensland Real Estate Commission Disputes

A seller refuses to pay. The sale completed, the contract is signed, the property has settled — and now they’re claiming the commission was never properly earned. You know the work you did. The question is whether you can prove it to a tribunal that operates by its own rules and doesn’t take kindly to agents who show up with a folder of half-organised emails and verbal assurances.

QCAT can resolve disputes between agents and clients regarding commission payments or other fees, and it does so on the evidence placed before it. Understanding precisely what evidence carries weight — and what gets you nothing — is the difference between recovering what you’re owed and writing off months of work.

How QCAT Approaches Evidence in Commission Disputes

The Queensland Civil and Administrative Tribunal is an independent tribunal established under the Queensland Civil and Administrative Tribunal Act 2009 (Qld). It resolves a wide range of civil disputes and administrative reviews, and its primary purpose is to provide a forum that is accessible, efficient, and affordable for people across Queensland.

That accessibility cuts both ways. The informality that makes QCAT approachable also means parties sometimes underestimate how seriously the tribunal treats evidence. Evidence describes, explains, demonstrates or supports a party’s claims about what happened in the matter. It is the body of facts and information you collect and submit to support and prove your argument. QCAT will make a final decision in the matter based on the evidence presented. The tribunal does not investigate on your behalf. It decides based on what is in front of it.

All information and material to be considered by QCAT in civil matters must be submitted in writing and also provided to each other party in the matter. This procedural requirement has real consequences. Failure to provide copies of your evidence to other parties involved with your matter will result in delays, adjournments, evidence not being considered by QCAT at hearing and in some instances, orders for you to pay another party’s costs, for example, costs of legal representation.

In addition to the application and response, parties may wish to file submissions or other material to support their claim or response. This may include filing statements of evidence, witness statements, expert reports, electronic evidence, documents and submissions. In a commission dispute, each of these categories has a specific role to play.

The Foundation: The Form 6 Appointment

Before any commission claim succeeds, one threshold question dominates: was the agent validly appointed? Without a compliant appointment, the evidence of what the agent actually did is largely irrelevant.

The general requirements which must be satisfied in order for the PO Form 6 Appointment to be valid are listed in section 104 of the Property Occupations Act 2014 (Qld). It is important that agents are aware that section 112(4) of the PO Act mandates that any appointment is ineffective from the time it is made if the appointment does not comply with section 104 of the PO Act.

The consequences of non-compliance are binary and severe. Without a valid appointment in place, an agent is not entitled to claim its commission for services they purport to provide and face penalties of 200 penalty units. QCAT has applied this principle without mercy. QCAT dismissed an agent’s claim for commission in 2016 because the agent used the outdated PAMDA Form 22a appointment of real estate agent (and should have used the POA Form 6). QCAT held the failure by the agent to use the appropriate POA Form 6 required under the current legislation meant the agent was not formally appointed by the client and was not entitled to claim any commission.

When lodging a commission dispute at QCAT, the signed Form 6 must be the first exhibit in your bundle. The signed version — not a template, not an unsigned copy — bearing both parties’ signatures and clearly identifying the property, the agency type, the commission rate (inclusive of GST), and the term of the appointment. It is critical that the Form 6 is filled out correctly. An incomplete form may impact the real estate agent’s ability to claim commission for the sale of the property.

The agency type specified in the Form 6 matters directly to what you then need to prove about your conduct. Under an exclusive agency agreement, the agent has the right to claim the agreed commission for the sale of the property, whether or not they are the effective cause of the sale. For example, under an exclusive agency agreement, the agent can claim commission even if the seller sells the property themselves, or it is sold through another agent. By contrast, under an open listing agreement, only the agent who is the effective cause of sale can claim commission for the sale.

This distinction shapes the entire evidentiary burden. An exclusive agency agent needs to prove the Form 6 was valid and in force at settlement. An open listing agent needs to prove causation as well.

Documentary Evidence QCAT Relies On

The Signed Contract and Settlement Confirmation

The contract for sale — fully executed, identifying the parties, property address, and sale price — establishes that a transaction occurred. This is the baseline. Without a settled contract, there is no commission trigger.

Alongside the contract, agents should file the settlement confirmation from the conveyancer, solicitor, or PEXA settlement statement. This establishes that completion actually occurred and confirms the final sale price from which commission is calculated. Where a deposit was forfeited without settlement, the contract termination notice and any correspondence confirming the forfeiture event will be the relevant documents.

The calculation itself must also be documented. Present a clear, itemised commission calculation derived from the final sale price as specified in the Form 6. QCAT does not assume the arithmetic — agents should show it explicitly, including whether the figure is GST-inclusive, consistent with the appointment.

Marketing and Activity Records

In disputed matters — particularly open listings and “effective cause” arguments — the agent’s working file is the evidence that proves the connection between the agent’s actions and the eventual sale. This includes:

• Marketing materials: signed or dated versions of any online listing, print advertising, or signboard copy confirming the agent’s involvement from a specific date
• Inspection records: open home registers, private inspection logbooks, or CRM-generated visit logs showing the buyer’s attendance at the property
• Correspondence: emails or text messages between the agent and the eventual buyer, demonstrating communication before any competing agent became involved
• Offers and negotiations: written offers, counter-offer records, and any notes from price negotiation

In most transactions, the commission rate is specified in the Form 6 appointment signed by the seller. But the activity log tells the story of how the sale came about — and in a contested effective-cause dispute, that story is what QCAT weighs.

Written Statements and Affidavits

In most minor civil dispute cases, evidence should be lodged in writing as soon as possible prior to the hearing, and a copy must be given to the other party. The primary vehicle for personal accounts at QCAT is the written statement or affidavit.

It is important that the evidence you present to QCAT is clear, concise and understandable. To assist the QCAT decision-maker and other parties to understand your evidence, agents should provide statements or affidavits for each of their witnesses.

An agent’s own statement should address the chronology of events precisely: when the Form 6 was signed, when the property was listed, when the buyer was first introduced, how negotiations progressed, and when the commission obligation crystallised. Vague recollections do not assist a tribunal. Dates, names, and specific interactions do.

If the buyer can confirm in a statement that they first became aware of the property through the agent — rather than through a later agent or the seller directly — that corroboration can be decisive in an open listing dispute.

Electronic Evidence: Emails, Texts, and CRM Records

The majority of real estate transactions are now largely conducted via email and messaging apps. QCAT accepts electronic evidence and agents should ensure it is presented in a usable format. Printed email threads with headers visible (sender, recipient, date, time), or screenshots of text exchanges with identifying information, are routinely submitted and considered.

Parties may file electronic evidence as part of their statements of evidence and supporting material. When filing digitally through QCAT’s online portal, QCase, parties should upload documents as individual documents rather than as one large document or bundle.

CRM-generated reports — particularly those time-stamping buyer enquiries, scheduled inspections, or property alerts — carry more weight than a simple written assertion because they originate from a system record rather than from the agent’s memory. Agents whose agencies maintain disciplined CRM records have a structural advantage at QCAT.

Witness Evidence

If an oral hearing is scheduled, the parties must attend, present their case and bring witnesses to give evidence if required. Written statements should be lodged in advance, but witnesses may also be called to give oral evidence at the hearing itself.

In commission disputes, useful witnesses include:

• The salesperson who conducted negotiations, if different from the principal
• A colleague who was present at a key negotiation or inspection
• The buyer, who may be willing to confirm how they first came to know of the property
• Any third party who can verify specific dates or interactions relevant to the effective cause question

Do not wait until the day of the hearing to give the other party material you wish to rely upon. Ambushing the other side with witness statements on the day undermines your own credibility and may result in an adjournment at your expense.

While Hearing Support Officers may give procedural advice about the presentation of evidence, the decision about what evidence may be received and how it is received is a matter for the QCAT decision-maker hearing the dispute. The member has broad discretion, but is guided by what is probative and what is fair to both parties.

What QCAT Will Not Accept — Common Evidentiary Failures

Agents who lose commission disputes at QCAT frequently do so not because their claim was wrong in substance, but because their evidence was inadequate. The most common failures are:

Reliance on oral representations without supporting documentation. An agent who claims the seller verbally agreed to pay commission regardless of agency type will not succeed on that claim alone. Without written evidence — even a confirmatory email — the tribunal has no basis to prefer one party’s account over another.

An invalid or outdated appointment form. As established above, this is a threshold issue. The Property Occupations Act 2014 states that a property agent is not permitted to act as an agent on behalf of a client in the absence of a valid appointment in the approved form. If you fail to complete a Form 6 correctly, or it’s incomplete, you may not be properly appointed to act, which ultimately could result in a loss of entitlement to commission.

Failing to serve evidence on the other party. Failure to provide copies of your evidence to other parties involved with your matter will result in delays, adjournments, evidence not being considered by QCAT at hearing and in some instances, orders for you to pay another party’s costs.

Submissions exceeding the page limit without prior arrangement. Any submissions or evidence exceeding 30 pages must be filed in hard copy in duplicate. Ignoring procedural requirements creates the impression of a party who does not take the process seriously — which is not how you want to be perceived when asking for a payment order.

Late evidence. Written evidence, submissions and any other applications must be filed in the QCAT registry in accordance with the dates directed in the directions issued by QCAT. Directions issued after an application are deadlines, not suggestions.

The Effective Cause Question and the Evidence It Requires

“Effective cause of sale” is the most contested factual question in open listing commission disputes. The courts and QCAT look at what the agent actually did to bring the parties together and move the transaction to exchange — not merely at who was appointed last or who happens to have a signed Form 6 in force at settlement.

In one notable case, a Gold Coast agency introduced a buyer for a property priced between $1.9 million and $2 million. After the agency’s exclusive period ended, another agent closed the sale at $1.752 million. The first agency claimed commission as the “effective cause of sale.” Initially, the court awarded the commission to the first agency; however, on appeal, the decision was reversed, highlighting the importance of the second agent’s role in finalising the sale.

This case demonstrates that QCAT and the courts do not treat “introduced the buyer” as automatically equivalent to “effective cause.” The evidence must show a direct and substantial causal link between the agent’s actions and the eventual contractual commitment. In practice, this means:

• Correspondence showing the agent introduced the buyer to the specific property and that the buyer’s interest was sustained through the agent’s ongoing efforts
• Evidence that no significant break in continuity occurred between the agent’s involvement and the contract signing
• Records demonstrating the agent’s role in price negotiation, addressing buyer concerns, or facilitating access to the property

Where a second agent later closes a sale at a materially different price after active involvement, that agent’s contribution may displace the first agent’s effective-cause claim — regardless of who initially introduced the buyer. The evidence of what each agent did and when is determinative.

Preparing and Filing Your Evidence Bundle

Whether you are the applicant or respondent, it is important that you understand what evidence is and how best to prepare it appropriately for the QCAT decision-maker.

A well-organised evidence bundle for a commission dispute should be structured logically, not chronologically. Begin with the foundational documents — the Form 6, the contract, the settlement confirmation — then move to the activity evidence, then the written statements. Each document should be clearly identified by a label or index.

QCAT’s online portal, QCase, allows parties to securely file applications, referrals or documents electronically, view, manage and respond to their minor civil dispute case. This fully-digital case management system allows parties to view case information and documents 24 hours a day, 7 days a week, and lodge documents any time on any day of the week.

Where documents are voluminous, prioritise relevance. A QCAT member reading your evidence bundle is not conducting a discovery exercise — they need to quickly understand what happened, when, and why it supports your claim. Irrelevant padding dilutes the persuasive force of the material that matters.

QCAT aims to resolve disputes quickly and with minimal formality. It often uses alternative dispute resolution processes, including mediation. In some matters, QCAT will schedule a mediation before a final hearing. Your evidence bundle is also relevant to that process — arriving at mediation without organised documents to support your position weakens your negotiating stance significantly.

What This Means for Queensland Agents

In a QCAT evidence QCAT real estate commission dispute in Queensland, the outcome is almost always determined before you walk into the hearing room. The hearing itself is an opportunity to present evidence — but only evidence that has been properly prepared, correctly filed, and served on the other party in accordance with directions.

Several practical conclusions follow:

Start the paper trail at the beginning, not after the dispute arises. The CRM record, the signed open home register, the email introducing the buyer — these are your evidence. Create them as a matter of practice, not in anticipation of litigation.

Treat the Form 6 as a threshold document, not a formality. It is critical that sales agents ensure that the PO Form 6 Appointment has been correctly completed and complies with all legislative requirements. An agent who is denied commission due to an outdated or incomplete Form 6 has no recovery path. The form must be current, complete, and signed before any services are provided.

File early, serve promptly, organise clearly. QCAT will not reward a disorganised case with a sympathetic outcome. The decision-maker works from what is in the file. It is important that the evidence you present to QCAT is clear, concise and understandable.

Understand what you need to prove based on your appointment type. An exclusive agency agent and an open listing agent face fundamentally different evidentiary tasks. Know which test applies to your matter before assembling your case.

Consider legal assistance for high-value disputes. Although QCAT is designed to be accessible, many matters involve legal, procedural, or evidentiary issues that can affect the outcome. Having a lawyer present can be particularly valuable in complex or high-value disputes. For commissions in the tens of thousands of dollars, professional preparation of your evidence and submissions is worth the investment.

Finally, if a QCAT order is made in your favour and the other party fails to comply, the QCAT decision is taken to be an order of the court and can be enforced in the same ways as an order of the Magistrates Court. The evidentiary effort that wins the hearing also supports that enforcement process.
