What Is Sole Agency in Queensland Real Estate? Definition and Agent Guide

A vendor calls you on a Friday afternoon, ready to list. They want one agent, one strategy, and one point of contact — but they also want to know that if they somehow find a buyer themselves over the back fence, they won’t owe you a cent. That arrangement has a specific name in Queensland law: sole agency. It is the appointment of a single agent as the only person authorised to sell a property, and for residential property it is capped at a maximum term of 90 days under the Property Occupations Act 2014 (Qld). Understanding exactly what a sole agency is — and, critically, what it is not — is foundational knowledge for every Queensland agent.

How Sole Agency Works in Queensland Real Estate

The Mechanics of the Appointment

Queensland agents must be formally appointed in writing before they are entitled to sell a property or charge commission. This is done using the prescribed Appointment of Property Agent (Form 6) under the Property Occupations Act 2014 (Qld). A sole agency appointment is formalised within that Form 6 by selecting the sole agency category and specifying the agreed term.

A Form 6 is a formal agreement between a real estate agent and a seller, used to appoint the agent to act for the seller in the sale of their property. Its full name is Form 6 – Appointment and reappointment of a property agent, residential letting agent or property auctioneer, and it must be completed correctly, signed and dated by both parties for the agent to be properly appointed. Without a properly executed Form 6 in place before services commence, the agent’s entitlement to commission is at serious risk.

The term of a sole or exclusive agency can be negotiated between the parties, up to a maximum term of 90 days. The parties can opt for the agreement to revert to an open listing agreement automatically after the sole or exclusive agency period. This rollover provision is worth discussing with sellers up front — it gives the agent continuity of engagement while giving the seller flexibility once the protected term expires.

What “Sole” Actually Means for Commission

The defining characteristic of a sole agency is not just exclusivity of appointment — it is a specific commission entitlement rule that distinguishes it from both an exclusive agency and an open listing. The only difference between an exclusive agency and a sole agency is the extent of the entitlement of a selling agent to receive an agreed commission or other reward on the sale of particular property. Under an exclusive agency, a selling agent is entitled to receive an agreed commission whether or not the selling agent is the effective cause of the sale. However, if the sale was subject to a sole agency, the selling agent would not be entitled to the commission if the seller was the effective cause of the sale.

In plain terms: under a sole agency, if the seller independently finds the buyer — without any involvement from the agent — no commission is owed. That is the fundamental trade-off. A sole agency is similar to an exclusive agency — you can still potentially claim a commission if another agent sells it. Unlike an exclusive agency, you are not entitled to a commission if the client sells it themselves.

This distinction matters enormously in practice. A vendor who has a genuine prospect lined up — a neighbour, a family member, a colleague — may prefer a sole agency precisely because they retain the right to transact privately at no cost. An agent who does not clearly explain this difference upfront creates the conditions for a commission dispute.

The 90-Day Cap and Term Management

The period of the appointment must be stated. For residential property sales, any exclusive or sole agency appointment is subject to a statutory maximum of 90 days. If you want to continue beyond this, it must be renewed in writing.

If the parties wish to extend the exclusive or sole agency beyond 90 days, they can only do so in the last 14 days of the agreement. If the appointment is for 60 days or more, it must stay in place for at least 60 days. Otherwise, the appointment may be terminated in writing with 30 days notice by either party.

These rules have real operational consequences. An agent who secures a 90-day sole agency and then allows it to lapse — without either renewing it or transitioning to an open listing — loses the protection of the appointment entirely. Commission claims made after the appointment expires will not succeed.

Why Sole Agency Matters for Queensland Agents

Commission Protection and the Effective Cause Test

Under a sole agency, your commission is protected whenever you — or any other agent — brings about the sale. The one scenario where your entitlement falls away is where the seller is the effective cause. The only difference between an exclusive agency and a sole agency is the extent of the entitlement of the selling agent to receive an agreed commission. Under an exclusive agency, the agent will be entitled to the commission agreed whether or not the agent is the effective cause of the sale. Where the agency is a sole agency, the agent would not be entitled to the commission if the seller is the effective cause of the sale.

For most Queensland residential sales, this is not a meaningful limitation. The seller rarely finds a buyer independently while an agent is actively running a marketing campaign. Where it becomes relevant is in off-market or tightly networked scenarios — particularly at the prestige end of the market, or in regional Queensland where sellers often have direct community connections with potential buyers. An agent working in those conditions should factor this into the listing conversation and, where appropriate, consider recommending an exclusive agency instead.

Why Agents Should Care About the Appointment Type

Many Queensland agents default to sole agency without fully appreciating what they are giving up. An exclusive agency provides stronger commission protection — particularly against the scenario where a seller-introduced buyer completes a sale during the agency term. Exclusive or sole agency: the agent is usually entitled to commission if the property sells during the exclusive period — even if you or another agent introduce the buyer. That protection under an exclusive agency extends to seller-introduced buyers; sole agency does not.

At the same time, sole agency is often easier to secure. Many sellers — particularly those listing for the first time or those wary of locking in tight obligations — are more comfortable signing a sole agency than an exclusive. The lower perceived risk for the seller translates directly into a faster appointment. For agents who are confident in their ability to find the buyer, this is not a material compromise.

Agents claim that the advantages of a sole or exclusive agency are that the seller only has to deal with one agent, only one key has to be given out, and there is a conscientious promotion of the property. On the other hand, owners need to be aware that the effect of these agencies is that the owner is locked into the agreement for a certain period. During this time, if the appointed agent’s promotion of the property is not satisfactory, the owner is unable to appoint other agents without breaching the agreement. Understanding both sides of this argument allows an agent to have a credible, balanced listing presentation rather than appearing to push a particular arrangement for self-interested reasons.

Double Commission Risk

Double commission disputes often turn on whether an exclusive appointment was still in force and who was the effective cause of sale. Avoid overlapping exclusive appointments, and if you change agents, end the existing appointment in writing and start the new one after the exclusive period ends. This advice applies equally to sole agency — if a seller appoints a second agent before the first sole agency term has ended, the seller may face liability to both agents. Principals running multi-agent teams need to ensure their systems flag appointment expiry dates to prevent this scenario from arising.

The Legal Framework: Sole Agency Queensland Requirements Under the Property Occupations Act 2014

Form 6 Validity Is Non-Negotiable

Agents should not provide any real estate services to their clients for payment until they have been formally appointed with a valid Form 6. The Form 6 will not be valid unless it meets the requirements set out in section 104 of the Property Occupations Act 2014 (Qld), and certain other requirements also apply.

Part 4, Division 1 of the Act establishes the requirement to appoint a property agent. Section 103 of the Act sets out particular requirements for appointing a property agent for sole or exclusive agency. That section requires, among other things, that the seller be given specific information about the nature of the appointment before they sign — including an explanation of the consequences if the property is sold during the term by someone other than the agent.

The Queensland Civil and Administrative Tribunal (QCAT) dismissed an agent’s claim for commission in 2016 because the agent used the outdated PAMDA Form 22a appointment (and should have used the POA Form 6). QCAT held that the failure to use the appropriate POA Form 6 meant the agent was not formally appointed by the client. This is not a technicality — it is a reminder that form compliance directly determines commission entitlement.

What Must Be in the Form 6 for a Sole Agency

The commission rate (percentage or dollar amount), whether GST is included or excluded, and how the commission is calculated must be specified. The specific trigger that entitles the agent to commission must also be clearly stated — for example, when an unconditional contract is formed, at settlement, or another clearly defined milestone. Marketing or advertising expenses, the total cost, when those costs are payable, and any rebates or discounts the agent receives in relation to those expenses must also be included.

Clarifying the commission with your client before the commencement of the contract is vital. Using phrases such as “to be negotiated” or anything similar can cause uncertainty, and risks the validity of the appointment by leaving it open to interpretation. A commission clause that is vague or incomplete can render the entire appointment ineffective for the purposes of recovering commission.

Reappointment Rules

A real estate agent may be reappointed for a sole agency for the sale of residential property for one or more terms of not more than 90 days. When reappointing, the agent must use the current version of the Form 6. As a real estate agent, you must be properly appointed by your client before providing any services, which must be done by completing this form. You’d be surprised how many instances agents have been denied their commission for using either the wrong or outdated form.

The reappointment must also comply with the timing restrictions: if the parties wish to extend the exclusive or sole agency beyond 90 days, they can only do so in the last 14 days of the agreement. Attempting to reappoint outside this window creates an ineffective reappointment, meaning the agent loses protected status.

Obligations Before Listing

Under section 19 of the Property Occupations Regulation 2014, a real estate agent must, before listing a property for sale, take reasonable steps to find out or verify ownership of the property they are selling. This obligation applies regardless of the appointment type. The real estate agent should verify the seller’s identity before they are appointed, and only take instructions from the legal owner(s) of the property. This is a practical compliance step that sits outside the Form 6 itself but is a mandatory pre-listing obligation.

What Queensland Agents Need to Know About Sole Agency

Distinguishing Sole Agency from Exclusive Agency in Conversation

Many sellers — and some newer agents — use “sole agency” and “exclusive agency” interchangeably. They are not interchangeable. The distinction has direct financial consequences. When taking a listing, it is worth walking the seller through both options explicitly, explaining that under a sole agency they retain the right to sell privately without commission liability, while under an exclusive agency the commission is payable regardless of who finds the buyer.

This conversation should be documented. Keep key negotiations in writing — emails, letters and signed documents form a clear trail. If a dispute arises later over whether a seller-introduced buyer triggers commission, having a clear record of the pre-appointment discussion assists significantly.

Managing the 90-Day Term Actively

A 90-day sole agency does not manage itself. Agents should diary the appointment end date and the 14-day reappointment window — the period within which a reappointment can be executed if the property has not yet sold. For residential exclusive or sole agency appointments, the law caps the term at 90 days. Use a reasonable period and diarise the end date. If you’re happy with your agent, renew in writing.

For agents operating within a principal’s office, this is a systems matter as much as an individual compliance matter. A CRM or listing management platform that flags appointment expiry 20–30 days before the end of the term gives sufficient lead time to discuss reappointment with the seller without creating pressure or urgency.

In the case of appointments of 60 days or more under a sole or exclusive agency, although either party can end the appointment by giving 30 days written notice, the appointment must run for at least 60 days unless both parties agree to an earlier end date. This means an agent who secures a 90-day sole agency has meaningful term protection and cannot simply be walked off the listing by a seller after three weeks without the seller either paying out the balance of the term or waiting until the 60-day mark.

Record-Keeping and the Effective Cause Test

Because a sole agency commission entitlement hinges on whether the agent — rather than the seller — is the effective cause of sale, records of buyer contact become critical. Ask your agent to keep a record of inspections, enquiries and offers. If a buyer reappears later, those records help resolve any “effective cause of sale” questions quickly. Every inquiry logged, every inspection recorded, and every buyer interaction documented is potential evidence in a commission dispute.

This is particularly relevant when a buyer first contacts the agent, goes quiet for several weeks, and then contacts the seller directly. The agent’s logs demonstrating prior introduction and communication with that buyer will be central to any commission claim.

Prior Appointments: Check Before You Sign

It is important that you know whether your client has already appointed another agent to act as a real estate agent to perform the service — especially if you’re acting under a non-exclusive appointment. This could become critical when determining whether you are the effective cause for the sale if another agent has previously acted for your client.

Before executing a Form 6 for a sole agency, ask the seller directly whether there is an existing appointment in place with another agent. If there is, and it has not yet expired, the seller cannot validly appoint a new agent on a sole or exclusive basis without first terminating the existing appointment in writing. Proceeding otherwise creates a double commission exposure for the seller and a potentially unenforceable appointment for the incoming agent.

What This Means for Queensland Agents

Sole agency is the most common listing appointment type in Queensland residential real estate. Its appeal is straightforward: the seller gets single-agent focus and clear accountability; the agent gets protected commission rights against all buyers except those the seller finds entirely independently. For the sale of residential property, the term of a sole agency is negotiable up to a maximum of 90 days.

The risks are equally straightforward. A Form 6 that is incomplete, outdated, or executed after services have commenced may be unenforceable. An appointment that lapses without renewal reverts to an open listing, stripping the agent of protected status. A commission entitlement under a sole agency that was never explained to the seller — particularly the seller-sale carve-out — is one that a seller will dispute with some justification.

The practical discipline is this: use the current Form 6, complete it fully, ensure the commission trigger and term are unambiguous, explain the difference between sole agency and exclusive agency to the seller before they sign, diarise the term and the reappointment window, and keep thorough records of every buyer interaction from the first day of the appointment. Without a valid appointment, an agent cannot legally claim commission for a sale. That single fact should drive every compliance habit in the listing process.

Agents who treat the Form 6 as an administrative afterthought will eventually learn its importance the hard way — in a QCAT hearing without a commission they believed they had earned. Agents who treat it as the foundation of the agency relationship will find it protects them consistently throughout their career.
