What Is Rental Increase in Queensland Real Estate? Definition and Agent Guide
A rental increase in Queensland is a formal uplift to the rent amount payable under a residential tenancy, governed by the Residential Tenancies and Rooming Accommodation Act 2008 (Qld) (RTRA Act). Under Queensland law, rent for any given premises can only be increased once in any 12-month period, and the property manager or owner must give at least two months’ written notice for a general tenancy before that increase takes effect. Get the frequency wrong, the notice short, or the paperwork incomplete, and you are not just dealing with a dispute — you are committing an offence.
How Rental Increase Works in Queensland Real Estate
The 12-Month Rule: Property, Not Tenancy
The single most important thing to understand about the rental increase Queensland definition is that the 12-month restriction runs with the property, not the tenancy agreement or the tenant. From 1 July 2023, Queensland rental laws limited the frequency of rent increases to once a year for all tenancies. From 6 June 2024, that annual rent increase frequency limit was tightened further so it now applies to the property, rather than the tenancy.
This change has significant practical consequences. The law prevents a lessor, agent or provider from increasing rent on a property less than 12 months after the last increase. The 12-month limit applies even if the last rent increase to the property related to a different residential tenancy agreement, there has been a change of tenants occupying the property, or there has been a change of ownership of the property.
In other words, if you take on the management of a property that had a rent increase eight months ago under a previous agent, the owner cannot increase the rent for another four months — regardless of what the new tenancy agreement says. Under Section 93 of the RTRA Act, you cannot increase the rent less than 12 months after the last rent increase for the premises. This 12-month rule applies across tenancies — meaning if the previous landlord increased the rent six months ago and you’ve since purchased the property with a new tenant, you cannot increase the rent until 12 months after that previous increase.
Notice Requirements
Notice periods differ depending on the type of tenancy. The rent can be increased by giving at least two months’ notice prior to or on the commencement of the periodic agreement for general tenancies, or at least four weeks’ notice prior to or on the commencement of the periodic agreement for rooming accommodation agreements.
The notice must be in writing and must clearly state the new rent amount and the date the increase takes effect. There is no single prescribed RTA form for a rent increase notice in a periodic general tenancy — a signed, dated letter or written notice identifying the property, the current rent, the new rent, and the effective date satisfies the requirement, provided it is served with adequate lead time.
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’ written notice for a general tenancy, or four weeks’ notice for a rooming accommodation agreement, and it has been at least 12 months since the last increase for the premises or room. If the fixed-term agreement does not already include a rent increase clause, the owner simply cannot increase the rent mid-term.
End of Fixed Term: A Different Pathway
When a fixed-term agreement is coming to an end, there is an alternative pathway. The property manager or owner and tenant can agree to a rent increase at the end of a fixed-term agreement by entering into a new agreement. However, it must be at least 12 months since the last rent increase. There is no requirement to serve a formal notice about the increase when using this pathway. The increase is effectively agreed to through the terms of the new agreement itself.
If the tenant does not sign a new agreement, the tenancy rolls over to periodic on the same terms and conditions, and any rent increase must then follow the standard two-month written notice process.
Recording the Increase: A Mandatory Obligation
As required by the Act, the property manager or owner must include the date of the last rent increase for the premises in the tenancy agreement (Form 18a/Form 18b/Form R18). This is not optional. The date of the last rent increase must be included in the tenancy agreement. Tenants have the right to request written proof of the last rent increase during the tenancy, and the property manager or owner must provide this information within 14 days of receiving the request — it is an offence not to do so.
Why Rental Increase Matters for Queensland Agents
The Compliance Stakes Are High
The penalty regime around rent increases is not trivial. It is an offence under the Act to increase the rent in less than 12 months, with a maximum penalty of 20 penalty units. Some sources report higher penalty figures depending on the specific provision: it is an offence to increase the rent more than once within a 12-month period, with the maximum penalty for non-compliance approximately $8,345 as of January 2026. Failing to state the date of the last rent increase in a new tenancy agreement carries a maximum penalty of approximately $6,676.
Those figures represent personal exposure for the property manager, not just the owner. The RTA has the authority to investigate and take enforcement action, and it can share information with other government agencies. Agents who manage large portfolios and apply blanket annual rent reviews without first verifying the last increase date for each individual property are particularly exposed.
Market Context Makes This Consequential
The rental increase provisions matter because Queensland’s rental market has been under sustained upward pressure. Brisbane’s rental market tightened further through the December quarter, with median rents for all dwellings climbing 3.1 per cent quarterly and 6.3 per cent over the past year. Properties in Queensland and South Australia dominated rent growth over the past 12 months, with both capital city and regional markets in both states recording the strongest rises. Median advertised rent prices in Brisbane rose 8.3% over the past year.
Against that backdrop, owners are motivated to review rents frequently, and tenants are increasingly aware of their rights. South East Queensland saw rent costs rise across the region. Of the top 10 postcodes with the largest increases, nine postcodes are located on the Gold Coast, Sunshine Coast or in Brisbane. Cairns took tenth place with a year-on-year increase of $80 per week. When every postcode is a headline, tenants read those headlines — and they know the rules about how often rent can go up.
No Cap on the Amount — But Excessive Increases Can Be Disputed
Unlike some other Australian jurisdictions, Queensland does not impose a statutory percentage cap on how much rent can increase. There is no automatic cap on the dollar amount of an increase, but increases must be reasonable and can be reviewed by the tribunal.
This is where agents face a different kind of risk. A tenant or resident can dispute the increase if they feel it is excessive by discussing the issue with the property manager or owner. If the tenant or resident still feels the increase is excessive, they can apply for dispute resolution once the new agreement is signed. 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. They have the authority to either approve the increase, reduce it, or disallow it altogether.
A defensible rent increase is one supported by current comparable market evidence. Agents who document their market appraisal at the time of issuing a rent increase notice are in a far stronger position if the matter is ever tested at QCAT.
Legal Requirements and Common Mistakes in Queensland Rental Increases
The Obligation Survives a Change of Ownership
One of the most common errors agents encounter when taking on a new management is treating a change of ownership as a reset. It is not. 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. If you acquire the management of a recently sold investment property, your first step should always be to establish — in writing — the date of the last rent increase before issuing any notice.
A property manager or owner is considered to have evidence of the last rent increase if they or their agent — such as a real estate agent, property manager, or lawyer — has this information. For a newly purchased property being tenanted for the first time, the date of the last rent increase is the date the property is first rented.
Fixed Term Does Not Mean You Can Increase Freely at Renewal
There is a persistent misconception that rolling a fixed-term tenancy into a new fixed-term agreement allows the owner to set any rent they choose. The 12-month rule still applies. Landlords can only raise the rent of a property after a period of 12 months, and that rule exists regardless of whether the new tenancy is a rollover or a fresh agreement with the same or a different tenant.
The Bond Can Move — But Has Its Own Rules
When a rent increase is processed, there is an optional but often overlooked obligation around the rental bond. 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. Any extra bond must generally be lodged with the RTA using a Bond Lodgement (Form 2) or the Bond Lodgement Web Service. The tenant must pay the increase in bond by the date stated on the notice, which must be at least one month after the tenant received the notice. Note that the bond cap of four weeks’ rent still applies — you cannot use a rent increase to push the bond above that ceiling.
The Undue Hardship Exception Is Narrow
Owners will occasionally ask whether they can increase rent sooner than 12 months if their costs have risen sharply. There is a pathway, but it is narrow. 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 their ability to continue to pay the rent. QCAT is not simply a rubber stamp for owners who find the 12-month restriction inconvenient. The hardship must be genuine, material, and documented.
Applications for permission to increase rent within a 12-month period due to financial hardship — which commenced from 6 June 2024 — are classified as non-urgent tenancy disputes and must go through RTA dispute resolution first, before being brought to QCAT. That pathway is typically slow and contested. Owners considering this route need to understand the process before they reach for a notice.
Rooming Accommodation Is a Different Regime
For rooming accommodation agreements, the notice period is shorter: four weeks rather than two months. However, all the same substantive rules apply — the 12-month frequency limit, the obligation to record the last increase date, and the tenant’s right to dispute. If the rent in a rooming accommodation agreement covers both accommodation and a service, the 12-month period only applies to rent increases. This is relevant for providers who bundle services with accommodation — they cannot use service-fee adjustments to effectively circumvent the rent increase restrictions.
Rent Bidding and Increases Are Separate Issues
Since 6 June 2024, all forms of rent bidding have been banned in Queensland. All forms of rent bidding are banned. Rental property owners and managers must not solicit, invite or accept offers of rent above the advertised price. This means the rent increase process cannot be used as an invitation for a tenant to voluntarily offer more than the noticed amount. The increase is the increase — a specified sum, on a specified date, with the required notice.
What Queensland Agents Need to Know About Rental Increase
Verify Before You Issue
Before issuing any rent increase notice, confirm the date of the last rent increase for the premises — not the tenancy, not the current tenant’s agreement start date, but the actual last increase event for that address. Check the current tenancy agreement (Form 18a), the prior rental ledger, or the previous management authority documentation. If you cannot verify this, request it in writing from the incoming owner or outgoing agent. Operating without this information is operating blind.
Notice Timing Is Calculated Carefully
A two-month notice period for a general tenancy means two clear calendar months. If the current periodic rent falls due every four weeks, plan your notice so the effective date aligns with a rent payment date. Notices that take effect mid-cycle create accounting complications and are a common source of tenant disputes. Issue the notice with buffer — the law sets a minimum, not a target.
Your Rent Increase Recommendation Needs Market Evidence
When advising an owner on a rent increase amount, bring a current comparable market analysis to that conversation. 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. Your recommendation protects the owner — but it also protects you. An agent who increases rent well above market, without documented justification, may find themselves in the middle of a QCAT dispute with no supporting evidence. The RTA’s median rents data, available by postcode, is a publicly accessible baseline.
Dispute Resolution Is the First Step, Not QCAT
If a tenant disputes an increase, non-urgent tenancy disputes must go through RTA dispute resolution first, before being brought to QCAT. If the dispute cannot be resolved or is unsuitable for conciliation, the RTA will issue a Notice of Unresolved Dispute (NURD). The NURD is the ticket to QCAT. Agents and owners who bypass this step and proceed directly to the tribunal will have their application rejected. Know the sequence.
Exempt Lessors Exist — But Are Narrowly Defined
Rent increase requirements do not apply to exempt property managers or owners, or exempt providers. The Act provides definitions for an exempt property manager or owner and an exempt provider. In general, exemptions apply primarily to community housing providers where rent is calculated as a proportion of tenant income. Standard private rental properties, including those managed by licensed real estate agents, are not exempt. If an owner claims to be exempt, verify that claim against the RTRA Act definitions before acting on it.
What This Means for Queensland Agents
Rental increase is one of the most frequently mishandled elements of Queensland property management, and the consequences run in both directions. Issue an increase too soon and you are committing an offence. Issue one without the required notice and it will not be valid. Fail to record the last increase date in the new tenancy agreement and you face a penalty. Recommend an amount without market evidence and you risk QCAT scrutiny.
The legislative framework here is clear and has been progressively tightened since 2021. Between 2021 and May 2025, Queensland introduced a series of reforms that changed the rules on rent increases, bonds, entry notices, rental applications, and personal information handling. Several of these changes carry penalty provisions — meaning getting them wrong isn’t just a procedural inconvenience, it’s an offence.
The practical discipline is straightforward: treat each managed property as having its own rent increase clock, running from the address — not from the tenant or the agreement. Verify the last increase date before issuing any notice, issue written notices with adequate lead time, ensure Form 18a reflects the correct last increase date, and document your market analysis. If the owner wants to push above market, have that conversation clearly and record your advice in writing.
Queensland’s rental market will continue to generate pressure for owners to maximise returns. Your role is to do that lawfully, defensibly, and in a way that retains good tenants rather than triggering disputes that cost everyone time and money.
