What Is Open Listing in Queensland Real Estate? Definition and Agent Guide

An open listing is a non-exclusive agency agreement under which a seller appoints one or more agents to market their property, but only the agent who is the effective cause of the sale earns commission. The seller retains the right to engage other agents simultaneously and to sell the property themselves — without owing any agent a fee. An open listing is a written agreement entered between the owner and the selling agent to sell the property, under which the seller keeps the right to sell the property themselves or to appoint additional selling agents, and the appointed agent is entitled to be paid only if they are the effective cause of the sale. In Queensland, the term is formally defined in the Property Occupations Act 2014 (Qld) and sits alongside exclusive agency and sole agency as one of three recognised listing types. Understanding exactly what an open listing means — and what it does not — is essential for any Queensland agent accepting or managing one.

How Open Listing Works in Queensland Real Estate

The appointment mechanics

In Queensland, real estate agents are appointed by the seller signing a Form 6 Appointment or Reappointment of a Property Agent, under which there are three types of appointment. The open listing is one of those three, and it operates in a structurally different way from the other two. Under an open listing appointment, the agent receives the authority to market the property — but that authority is not exclusive. The seller can simultaneously sign Form 6 appointments with as many agents as they wish, each on open listing terms.

An open listing agreement does not require an end date, and may be terminated at any time in writing by either the agent or the client. This is a material operational difference from sole and exclusive appointments. Either party — you or your agent — can cancel an open listing at any time by notifying the other party in writing. There is no minimum term, no 60-day lock-in, and no 30-day notice period. The appointment is terminable on notice from either side, immediately. For an agent, this creates a fundamentally different risk profile than exclusive work.

The commission entitlement under an open listing is triggered by one concept only: effective cause of sale. An open listing agreement permits engagement of multiple agents, but only the agent who is deemed the effective cause of the sale can claim the commission. Being the first to show the property is not sufficient. Introducing a buyer is not, by itself, sufficient. The agent must demonstrate a direct and operative connection between their actions and the eventual contract. If a competing agent re-introduces the same buyer, or the seller accepts a contract brought in by a different agent entirely, the first agent earns nothing — regardless of work done.

The effective cause test

The effective cause of sale concept is embedded in the Property Occupations Act 2014 (Qld) and has a specific legal meaning in Queensland agency law. Where an owner appoints an agent to sell and a buyer purchases the property, the question of who is the effective cause of the sale — and therefore who is entitled to commission — depends on the particular circumstances. Courts have consistently held that the effective cause is the agent whose efforts were the real, proximate, and initiating cause of the transaction — not simply a contributing factor. An agent who introduces a buyer who later returns through another channel may struggle to establish that connection.

For agents working open listings in Queensland, this test means documentation matters enormously. Keeping records of inspections, buyer introductions, communication history, and written follow-ups creates the evidentiary foundation for any future commission claim. An undocumented introduction is very difficult to defend if disputed.

What triggers the right to commission — and what does not

Under an open listing, commission is only payable on a completed, unconditional sale. Under an open listing, the agent is only entitled to commission if the agent is the effective cause of the sale. Crucially, if the home does not sell, the agent is owed nothing. This contrasts sharply with an exclusive appointment, where the agent earns commission on any sale during the term regardless of who caused it. Under an open listing, even if the seller accepts the buyer’s offer the day after an agent’s inspection, the commission entitlement still depends on whether that agent was the effective cause — and the seller selling privately after receiving an open listing appointment from an agent owes that agent no fee at all.

Why Open Listing Matters for Queensland Agents

The commercial reality of working without exclusivity

Open listings are common in Queensland as a transitional arrangement. The appointment may include a provision that at the end of the term of an exclusive agency, the appointment of the agent continues under an open listing that may be ended at any time by the agent or the owner. This means many agents hold open listings not by choice, but as the natural evolution of an expired exclusive appointment. Principals managing multi-agent teams need to understand this: any exclusive listing that expires without a reappointment automatically moves into open listing territory unless the parties agree otherwise, and the agent’s protection against commission loss diminishes immediately.

Most exclusive appointments revert to open listings at the expiry of the term. It is important to note that even if the term of the exclusive appointment has expired, but the agent introduced a buyer to the property who purchases the property after the expiry of the term, the agent is still entitled to their commission. This is a critical point that agents frequently misunderstand. A buyer introduced during the exclusive term who subsequently contracts after the term has ended can still support a commission claim — provided the agent can demonstrate effective cause. The listing type has changed, but the introduction has not.

Open listing as a competitive environment

In most cases, agents working under an open arrangement will prioritise their exclusive listings over the open agreement. This means the property may be on the market for much longer than anticipated, and in turn this may drive the price down. This is the honest reality of open listing work. An agent with an exclusive listing has a guaranteed outcome if they produce a buyer — so they invest marketing resources accordingly. Under an open listing, the agent fronts marketing costs and effort with no certainty of return. Most experienced Queensland agents approach open listings with careful commercial judgment: they may act on them for known buyers, they will rarely commit significant vendor-paid advertising without exclusivity, and they will not invest in professional photography, floor plans, or digital campaigns with no fee protection.

The seller’s perceived benefit — multiple agents competing to find a buyer — does not always play out in practice. Open listings are less common than exclusive listings, and ultimately a seller should decide based on current market conditions, property type, location and the price they hope to achieve. For agents, the lesson is simple: when discussing listing type with a prospective seller, the value of exclusivity needs to be articulated plainly. Open listing means divided effort, diluted commitment, and no guarantee of return on campaign investment.

Risk of double commission disputes

One practical risk that arises in open listing situations — particularly when multiple agents are engaged — is the potential for competing commission claims. If two agents both claim they were the effective cause of sale, the seller can face competing demands. In an exclusive agency arrangement, the seller pays commission regardless of who sells the property, and if another agent sells it, they could potentially pay two commissions. While this specific risk is higher under exclusive arrangements, open listings carry their own complexity: if the seller simultaneously has open listing appointments with multiple agents and the question of effective cause is genuinely contested, the seller may face legal proceedings from one or more agents seeking to establish their claim.

Legal Requirements for Open Listing Appointments in Queensland

Form 6 and the Property Occupations Act 2014

Every open listing in Queensland — without exception — must be documented on a properly executed Form 6. A Form 6 is a formal agreement between a real estate agent and a seller used to appoint the real estate 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.

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. Section 104 of the Act governs the general content of an appointment — it must specify the property, the nature of the appointment, the services to be performed, and the commission or reward payable. Failing to include required particulars does not automatically make the document void, but it can seriously compromise the agent’s ability to recover fees.

The commission provisions and what must be stated

The commission provisions in a Form 6 open listing must be clearly expressed. 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. For an open listing specifically, the commission section must make clear that the fee is only payable on the agent being the effective cause of sale. Any ambiguity in this clause can be interpreted against the agent at the point of claim.

Queensland agents should also note that there is no prescribed commission rate for residential property sales in Queensland — commission is freely negotiable between the parties. Whatever rate is agreed must be stated clearly on the Form 6. The agreed commission and when it is to be paid should be clearly stated. It is also sound practice to document any agreed expenses — marketing costs or otherwise — separately within the Form 6, since under an open listing structure, recovering upfront campaign costs without a sale requires specific agreement in the appointment document.

No end date required, but termination must be in writing

Unlike sole and exclusive appointments — for which the maximum appointment term is 90 days — an open listing carries no maximum term and no mandatory end date. It continues until terminated. However, termination must be effected in writing by either party. An agent who verbally agrees to step aside, or who simply stops working the property, is not automatically off the hook for any obligations still contained in their Form 6 appointment. Always formalise a termination in writing and retain a copy.

The parties can opt for the agreement to revert to an open listing agreement automatically after the sole or exclusive agency period. If this option is selected on the Form 6, the transition from exclusive to open listing is automatic at expiry. Agents who select this option need to understand that from the moment of conversion, they lose all protection against a competing agent introducing a buyer. Any buyer they have introduced prior to expiry and who has not yet exchanged contracts is now at risk of being approached and contracted through a competing agent, with the original agent potentially losing their commission entitlement.

Conduct standards apply equally

A property agent must act in accordance with the client’s instructions regardless of listing type. The fact that an open listing carries less commercial protection for the agent does not reduce the agent’s obligations to the seller. Fiduciary duties, disclosure obligations under the Act, and the conduct standards prescribed under the Property Occupations Regulation 2014 (Qld) apply with equal force to open listing appointments as they do to exclusive ones. An agent holding an open listing is still required to act in the seller’s best interests, disclose any conflicts, and maintain accurate records.

What Queensland Agents Need to Know About Open Listing Practice

When to accept an open listing — and when not to

A commercially rational Queensland agent accepts an open listing in limited circumstances. The clearest case is where the agent has an identified, active buyer for the property and needs authority to present an offer. In that situation, the open listing provides the necessary legal authority to act and the effective cause of sale is already established by the agent’s direct involvement with that buyer. Accepting an open listing speculatively — without a buyer in hand — and then committing marketing resources to a property that any competitor can sell from underneath you is rarely sound business.

Open listings also make sense as a holding position after an expired exclusive appointment, where the seller has not yet decided whether to reappoint. The agent retains authority to continue working buyers they have already introduced, while the parties negotiate reappointment terms. This situation should not be allowed to drift indefinitely. Principals should train their teams to treat an open listing period as a transition, not a permanent arrangement.

The practical risk of buyer poaching

The absence of exclusivity under an open listing means that a buyer introduced by Agent A can, in theory, return to the property through Agent B and contract. If that happens, Agent A cannot claim commission simply because they showed the buyer first. With an open listing, the appointed selling agent is entitled to be paid only if they are the effective cause of the sale. This is not a theoretical risk — it happens in practice, particularly in competitive markets where multiple agencies are simultaneously marketing the same property.

To protect against this outcome, Queensland agents working open listings should:

• Log every buyer inspection with dated, written records (name, contact, date, property shown)
• Follow up every inspection in writing (email or SMS) so there is a documented trail of ongoing communication
• Ensure buyers who intend to make an offer do so through the agent directly, not by contacting the seller independently
• Move quickly — the longer a buyer sits in the pipeline without contracting, the greater the risk of displacement

Common mistakes with open listings in Queensland

The most frequent practical errors are: accepting a verbal open listing without a signed Form 6 (which provides no legal basis for a commission claim); failing to specify the commission clearly on the Form 6; and treating an expired exclusive period as an open listing without formally documenting the transition on a new or reappointment Form 6.

A second common mistake is assuming that because an open listing has no fixed end date, there is no urgency. The appointment of the agent can be terminated by either the owner or the agent at any time. That termination right works both ways. A seller can end an open listing the day before a buyer introduced by that agent contracts — and while the agent may still have an effective cause argument depending on the timeline, it introduces risk and potential litigation. Agents should work their open listings with the same urgency as exclusives, precisely because the safety net is absent.

What This Means for Queensland Agents

Open listing in Queensland real estate is defined, regulated, and documented differently from exclusive and sole agency — and it carries a fundamentally different risk structure for the agent. The key principles to carry into practice are straightforward.

An open listing requires a valid, signed Form 6 naming the type of appointment, the commission agreed, and any recoverable expenses. There is no fixed term, but termination must be in writing. The appointment can be terminated at any time by giving written notice and no end date is required for an open listing. The agent is entitled to the agreed commission only if the agent is the effective cause of sale. That effective cause standard is the single most important concept for Queensland agents working open listings — it determines whether work done translates into fees earned.

Agents should treat the open listing as a legitimate but conditional appointment. Do not decline them outright when a buyer is already in hand or when maintaining authority over an introduced buyer is the commercial priority. Do not commit significant campaign resources to open listings without a clear buyer pipeline or a parallel negotiation toward exclusivity. And never allow an open listing to exist without a properly executed Form 6 — the absence of documentation is the absence of a commission claim.

For principals running multi-agent offices, the discipline of tracking which agents hold open listings, which buyers have been introduced under them, and when exclusive periods expire is a basic risk management function. The Property Occupations Act 2014 (Qld) governs every appointment — open listing or otherwise — and the consequences of a poorly documented authority fall on the agent, not the seller.
