Disputing a Rent Increase in Queensland: Tenant Rights and QCAT Process

A tenant receives a rent increase notice and decides the amount is excessive. They’ve already spoken to the property manager, been told it reflects the market, and are no closer to a resolution. At that point, the question every agent managing that property — or advising on it — needs to answer clearly is: what does the dispute pathway actually look like under Queensland law, and how does QCAT fit into it?

Understanding this process in full is not optional knowledge for property managers. It shapes how you communicate increases to tenants on behalf of owners, how you document your file, and how you respond if a dispute escalates. This article covers the complete framework for disputing a rent increase in Queensland: the legislative foundation, the conditions a notice must satisfy before a dispute can even be raised, the RTA conciliation step, and the QCAT hearing process including what the tribunal weighs when determining whether an increase is excessive.

The Legislative Framework: What the RTRA Act Actually Says

Queensland rent increases are governed by the Residential Tenancies and Rooming Accommodation Act 2008 (Qld) — commonly referred to as the RTRA Act. Sections 91 to 94 of the Act set out the rent increase framework, including the frequency limit, notice requirements, and the process for challenging an excessive increase.

From 1 July 2023, Queensland rental laws limited the frequency of rent increases to once a year for all tenancies. From 6 June 2024, the annual rent increase frequency limit applies to the property, rather than the tenancy. This is a critical distinction. Since 6 June 2024, the 12-month minimum between rent increases is attached to the property itself — not the tenancy agreement and not the tenant. This means a landlord cannot reset the clock by signing a new lease with a new tenant or by renewing an existing lease.

It is an offence under the Act to increase rent in less than 12 months, with a maximum penalty of 20 penalty units. For a property manager, the practical implication is straightforward: before issuing any rent increase notice, you must confirm when rent was last increased for the premises, not just for the current tenant. The date of the last rent increase must be included in the tenancy agreement, and tenants have the right to request written proof of the last rent increase during the tenancy; the property manager or owner must provide this information within 14 days.

There is no legislated cap on the dollar amount or percentage by which rent can be increased in Queensland. There is no legislated cap on the amount of a rent increase. However, if a tenant believes the increase is excessive, they can apply to QCAT within 30 days to have it reduced or set aside. This is the core tension agents must manage: a lawful increase — correct timing, correct notice — can still be challenged and overturned if a tribunal member finds it excessive relative to the market.

Notice Requirements: When a Dispute Can Legitimately Begin

Before a tenant can dispute an increase, the increase must have been properly notified. A defective notice changes the situation entirely — the tenant may simply not be obliged to pay the higher amount, making formal dispute proceedings unnecessary.

Under section 91 of the RTRA Act, the required minimum two months’ written notice for a rent increase can be given before the periodic agreement begins, provided the increase takes effect after the fixed term ends and the tenancy becomes periodic. For rooming accommodation agreements, at least four weeks’ notice is required prior to or on the commencement of the periodic agreement.

Every notice must contain specific information. The notice should include the increased amount, the day the increase will take effect, and the date the rent was last increased for the premises. If any of these elements are missing, the notice does not comply with the Act. An agent who issues an incomplete notice on behalf of a landlord is exposing their client to an unenforceable increase and a potential dispute they cannot win.

Rent during a fixed-term agreement can only be increased in narrow circumstances. Rent cannot be increased during a fixed term unless it is stated in the tenancy agreement and all of the following occurs: the property manager or owner gives the tenant at least two months’ notice in writing for a general tenancy, and it has been at least 12 months since the last increase for the premises or room. The property manager or owner must also give the tenant separate written notice of the increase. It does not automatically come into effect because it is in the agreement.

Where a notice fails to meet these requirements, property managers should advise their clients promptly. Reissuing a compliant notice — provided the 12-month rule is satisfied and the timing is still workable — is far preferable to a formal dispute proceeding based on a defective document.

Two Grounds for Disputing a Rent Increase

When a tenant challenges a rent increase under Queensland law, they are effectively arguing one of two distinct things: either the increase was unlawful (the notice was defective, the 12-month rule was breached, or the increase was applied during a fixed term without authorisation), or the increase was excessive even though it was technically lawful. These are different situations with different remedies.

An unlawful increase — for example, one served within 12 months of the previous increase — is straightforwardly void. It is an offence under the Act to increase the rent in less than 12 months. The 12-month period applies even if the last rent increase was related to a different tenancy agreement with another tenant or by a previous agent or owner of the property. A tenant who identifies this breach is not required to pay the new amount, and the matter may be referred to the RTA for investigation.

An excessive increase is more nuanced. The Act does not define “excessive” by reference to a percentage or dollar threshold. Instead, QCAT must look at the circumstances of the tenancy and the broader rental market. A rent increase that is technically lawful — correct notice, correct timing — can still be reduced or set aside if QCAT considers it excessive relative to the market. The state of repair of the property is particularly relevant: if the property has significant maintenance issues, QCAT is less likely to support a large increase.

QCAT will consider comparable market rents, the state of repair of the property, the length of the tenancy, and other relevant factors. Crucially, the tribunal will not take the tenant’s personal income into account when deciding if the rent increase is excessive. The test is market-facing, not means-tested. A tenant cannot succeed by arguing they cannot afford the increase; they must demonstrate the increase is excessive against comparable properties.

This distinction matters for how property managers brief their landlords before issuing an increase. An owner who has deferred maintenance while requesting a significant rent jump is more exposed at QCAT than one whose property is well-maintained and whose proposed rent sits at the lower end of comparables.

The Dispute Pathway: From Direct Negotiation to QCAT

The dispute process in Queensland is sequential. A tenant does not simply file with QCAT — there are steps that must be taken first, and failing to follow them will result in a QCAT application being rejected.

Step One: Direct Discussion

A tenant or resident can dispute the increase if they feel it is excessive by discussing the issue with the property manager or owner. This first step is not a formality. Many rent disputes are resolved here — particularly when a property manager can clearly explain the market evidence supporting the increase, or when the owner is willing to moderate the amount rather than lose a reliable tenant.

For agents, this conversation is an opportunity to manage expectations on both sides. Presenting the tenant with current comparable rental listings from reputable platforms — demonstrating the proposed rent is broadly in line with the market — can defuse a dispute before it escalates. Equally, if the landlord’s proposed increase looks aggressive relative to actuals in the suburb, this is the moment to have that conversation with the owner.

Step Two: RTA Dispute Resolution

Before submitting a non-urgent tenancy dispute application with QCAT, property managers, owners, and tenants must first try to self-resolve their issues with the other party directly or complete the RTA dispute resolution process.

If the tenant still feels the increase is excessive, they can apply for dispute resolution once the new agreement is signed. They may also apply to QCAT for a decision if they meet the below requirements. The RTA’s dispute resolution service is free, and requests can be submitted online through the RTA’s Tenancy Dispute Resolution Web Service. A conciliator will facilitate the conversation between parties with the aim of reaching a negotiated outcome.

If conciliation succeeds, the agreed terms are recorded and the matter is resolved. If it does not, the RTA issues a Notice of Unresolved Dispute. This document is critical — it is the prerequisite for a QCAT application. A dispute resolution request to the RTA must be completed and the Notice of Unresolved Dispute received before applying to QCAT. The conciliation number from the Notice and a copy of the Notice itself must be provided.

Step Three: Application to QCAT

If a tenant believes a rent increase is unreasonable, they can apply to QCAT for a review. This application must be made within 30 days of receiving the rent increase notice. Tenants wishing to dispute a rent increase can use the Form 2 Application for Minor Civil Dispute — Residential Tenancy Dispute.

QCAT applications can be lodged via QCase, QCAT’s online portal for minor civil disputes. QCase allows parties to securely file applications, referrals, or documents electronically, view, manage, and respond to their minor civil dispute case. The fully-digital case management system makes filing and managing a case easier and more accessible by allowing parties to view case information and documents 24 hours a day, 7 days a week, and receive case updates and notifications in real time.

The Form 2 application should be accompanied by all supporting evidence: the rent increase notice, the tenancy agreement, the RTA Notice of Unresolved Dispute, records of comparable properties in the area, and any documentation relating to maintenance issues or the condition of the property. Completing Form 2 promptly and attaching evidence such as the lease, the rent increase notice, and any correspondence speeds up the review.

What QCAT Considers: The Excessive Rent Test

Once a rent increase dispute is before QCAT, the tribunal member must assess whether the proposed increase is excessive. The Act does not prescribe a formula — QCAT exercises discretion, weighing multiple factors.

The central consideration is market evidence. A tenant wanting QCAT to reduce or set aside an increase will need to demonstrate that comparable properties in the same suburb or area are renting for materially less than the proposed new rent. This means current rental listings, ideally at the time the notice was served, showing properties of equivalent size, condition, and location. Three to five solid comparables is typically the minimum persuasive threshold, though more is better.

The condition and state of repair of the property carries significant weight. A rent increase that is technically lawful can still be reduced or set aside if QCAT considers it excessive relative to the market. The state of repair of the property is particularly relevant: if the property has significant maintenance issues, QCAT is less likely to support a large increase. This means a tenant who has been raising maintenance concerns in writing — and can document the property manager’s or owner’s failure to address them — is in a stronger position than one who cannot.

Length of tenancy and the history of increases for the property are also relevant contextual factors. A long-term tenant who has received modest increases over many years is in a different position to a newer tenant receiving an aggressive jump from day one.

QCAT will consider a range of factors when determining if a rent increase is excessive, including current market rents, the condition of the property, and the length of the tenancy. The tribunal has the authority to either approve the increase, reduce it, or disallow it altogether.

One thing QCAT will not do is substitute a different increase based on what the tenant says they can afford. The test is objective: does this increase reflect the rental market, or does it depart from it without justification?

The Undue Hardship Exception: When a Landlord Can Apply to QCAT

The dispute pathway runs in both directions. There is also a narrow circumstance in which a property manager or owner can apply to QCAT — not to challenge a tenant, but to seek permission to increase rent within the 12-month minimum period.

A managing party may apply to QCAT for permission to increase rent within 12 months due to undue hardship. The tribunal must have regard to any representation made by the tenant in relation to affordability and ability to continue to pay rent.

If an owner faces genuine financial hardship because they cannot increase rent during the 12-month minimum period, they can apply to QCAT under Section 93B for an order permitting an early increase. QCAT may permit the increase, but must have regard to any representations made by the tenant about the proposed increase and its likely effect on the affordability of the premises and the tenant’s ability to continue paying rent. This is a narrow provision intended for genuine hardship — for example, a significant unexpected increase in mortgage repayments or rates — not a general workaround for the 12-month rule.

This provision is worth understanding because it demonstrates the symmetry of the QCAT process. Both parties can approach the tribunal; neither has an automatic upper hand. What QCAT will look at in both directions is evidence — documentation of the market, the property, and the financial realities of the situation.

Bond Implications of a Rent Increase

When a rent increase is implemented, the bond position may also change — and this is an area where property managers need to act carefully to avoid creating a separate point of dispute.

If rent is increased, the bond may be increased if it has been at least 11 months since the last bond increase or start of the tenancy. The property manager or owner must give the tenant at least one month’s notice in writing about the bond increase. From 30 September 2024, the maximum bond allowed to be taken is equivalent to 4 weeks’ rent for general tenancies and 2 weeks’ rent for moveable dwellings, or 3 weeks’ rent for moveable dwellings if electricity is provided, regardless of the weekly rent amount.

Where a tenant has disputed the rent increase and the matter is before the RTA or QCAT, property managers should not pursue a bond top-up until the dispute is resolved. Issuing a bond increase notice while a rent dispute is active creates administrative complexity and, in some circumstances, may appear coercive. The prudent approach is to wait for a final outcome before actioning any bond adjustment.

Rooming Accommodation: Different Notice, Same Dispute Rights

Rooming accommodation tenants — those in boarding houses, hostels, and similar shared arrangements — sit under the same broad framework but with different notice periods. Where it has been 12 months or more since the last increase for the resident’s room, the provider or agent must give at least four weeks’ notice in writing that rent will be increased. This notice must state how much the rent will increase by and when the increase will happen.

Disagreements may arise between residents and providers or agents about rent increases. Residents and providers or agents can usually resolve their disputes by talking to each other and finding out about their rights and responsibilities under the Act. If this does not work, the RTA’s dispute resolution service may be able to help. If they still cannot agree after dispute resolution with the RTA, an application may be made to QCAT for a decision.

The substantive test for “excessive” is the same for rooming accommodation as it is for general tenancies. QCAT assesses the increase against comparable accommodation in the area, the condition of the room and shared facilities, and the length of the resident’s occupancy.

Managing Disputes Professionally: Notes for Property Managers

Rent disputes create friction in the landlord-owner-tenant relationship. The way a property management team handles the process often determines whether the tenancy survives it.

The most common professional failure at this stage is poor communication. Many rent disputes arise not because an increase is unlawful, but because it is poorly explained or communicated. Providing clear notice, market evidence, and time for discussion helps maintain professional landlord-tenant relationships. Sending a compliant notice and nothing else — no context, no market rationale, no invitation to discuss — is technically sufficient but practically problematic. Tenants who feel blindsided are more likely to escalate.

When a dispute is lodged with the RTA, agents representing the property owner must act promptly. The conciliation timeline is short, and failure to engage constructively can result in the matter proceeding to QCAT without the owner’s position being adequately presented. At the QCAT stage, be aware that all parties involved in a matter before QCAT must usually represent themselves unless leave to be represented has been given. This means the agent may not be able to represent the landlord at the hearing as a matter of right — the owner should be prepared to appear personally, or seek independent legal advice about representation.

Agents who have kept clean, timestamped records — comparable rental evidence at the time of the notice, maintenance request logs, inspection reports, and all written correspondence about the increase — are in a far stronger position before a tribunal member than those who cannot reconstruct the factual basis for the proposed rent.

What This Means for Queensland Agents

Rent dispute management is a core property management competency, not a peripheral one. With the 12-month frequency limit now attached to the property and penalty exposure for non-compliance reaching 20 penalty units or more, the compliance stakes have risen.

The key practical points for agents:

• Confirm the date of the last rent increase for the premises — not the tenancy — before issuing any increase notice. This is now a legal requirement under the RTRA Act, and the date must appear in the tenancy agreement.
• Issue notices that contain all three required elements: the new amount, the effective date, and the date rent was last increased. A notice missing any of these elements is non-compliant.
• When a tenant disputes an increase, the correct sequence is: direct discussion, RTA conciliation, then QCAT — in that order. A QCAT application without a Notice of Unresolved Dispute from the RTA will not proceed.
• The test at QCAT is market-based, not means-tested. Prepare comparable rental evidence before the hearing, not after.
• A technically lawful increase can still be reduced or set aside by QCAT if it is excessive relative to the market. The condition and maintenance history of the property matters.
• Where a landlord faces genuine financial hardship and needs to increase rent within the 12-month period, QCAT does have a narrow jurisdiction under Section 93B of the RTRA Act — but this is not a routine workaround and requires proper application and evidence.

The QCAT rent dispute process is accessible, relatively low-cost for tenants, and increasingly well-understood by the tenant community. Property managers who understand it with equal clarity — and who advise their landlords accordingly — are better placed to manage rent reviews professionally, minimise escalation, and protect the value of the landlord-agent relationship over time.
