Rent Increases in Queensland: Rules, Notice Periods and How to Challenge One

A large increase is not automatically unlawful, and a small increase is not automatically valid. Queensland law separates three questions: when rent may rise, how the increase must be made, and whether the amount is excessive.

The rules below focus on general residential tenancies. Rooming accommodation and moveable dwelling agreements have related but sometimes different notice periods. Some government, community housing and legally defined exempt lessors are treated differently, so check the current RTA guidance if your housing is not an ordinary private rental.

The five-minute validity check

1. Find the last increase date for the premises. The new rent generally cannot take effect less than 12 months later.
2. Identify the agreement stage. Is this an increase during a fixed term, during a periodic agreement, or the rent in a proposed renewal?
3. Check the notice. For an increase during a general tenancy, it must be written and state the new rent, start date and last increase date, unless a specific exemption applies.
4. Count the notice period. General tenancies generally require at least two calendar months; rooming accommodation generally requires four weeks.
5. Diary the 30-day challenge deadline. Negotiating does not safely extend a statutory deadline.

A notice may be given before the 12 months expires, but the higher rent cannot take effect until the 12-month period has ended. The RTA's notice-calculation guidance treats months as calendar months and does not count the day the notice is served.

The 12-month rule follows the property

For most private rentals, the lessor or agent must not increase, or purport to increase, the rent less than 12 months after the last rent increase for the residential premises. Since 6 June 2024, that limit follows the property rather than restarting with a new tenancy.

This means a change of tenant, agent or owner does not ordinarily reset the clock. The Act gives an example: if Tenant A's rent increased on 1 November and Tenant B begins a new agreement the following February, another increase cannot take effect until the 12-month period has passed.

Worked timing example

Suppose the current rent first became payable on 26 August 2025. A written notice is emailed on 1 July 2026. The notice period can run while the 12-month clock is still running, but the proposed higher rent cannot lawfully start before both requirements are satisfied: at least two months after notice and at least 12 months after the previous increase. On these facts, the later date controls.

Do not estimate the date by counting 365 days. Use calendar dates and the RTA's current notice-calculation guidance, especially for end-of-month dates or postal service.

You can request proof of the last increase

If the previous increase date is unclear, section 93A allows a tenant to ask the lessor or agent in writing for evidence. Examples include a previous tenancy agreement, rent-increase notice or rent ledger. Unless an exemption applies, the evidence must be provided within 14 days and personal information about another person must be removed or de-identified.

“Please provide evidence of the date of the last rent increase for these premises under section 93A of the Residential Tenancies and Rooming Accommodation Act 2008. Please ensure any other person's personal information is removed.”

Keep the sent request and response. A new owner who lacks records is not automatically free to increase within 12 months; the RTA advises that the minimum frequency limit still applies.

Different rules for fixed-term, periodic and renewal agreements

Increase during a fixed term

Rent cannot rise during a fixed term unless the agreement provides for the increase and states the new amount or how it will be worked out. The increase must be made under that term, separate written notice must still be given, and the 12-month property limit must be met.

A vague term such as “rent may increase at the owner's discretion” may not satisfy the requirement to state the amount or calculation. The notice alone cannot create a mid-term increase that the signed agreement does not permit.

Increase during a periodic agreement

For a general tenancy, the owner or agent generally gives at least two months' written notice. For rooming accommodation, the RTA states four weeks. A notice can be given before a fixed term rolls into a periodic agreement, and the increase may start with the periodic tenancy if the notice and 12-month requirements are both met.

Higher rent in a new fixed-term agreement

The written-notice mechanism in section 91 does not apply to a rent change from one fixed-term agreement to the next. The new rent is instead a term of the proposed new agreement. However, the property-based 12-month frequency limit still applies.

A tenant who believes a significant rent change in a signed renewal is unreasonable can use the separate significant-change process. The tenant must first enter into the new agreement and generally lodge the dispute within 30 days. This creates a real decision point: signing preserves the tenancy on the new terms unless changed by agreement or order; not signing may mean no renewed fixed term. Obtain advice before committing if the timing or stakes are significant.

Warning signs that an increase may not be payable

• The start date is less than 12 months after the premises' last increase.
• An existing general tenancy received less than two calendar months' written notice.
• The notice omits the new amount, commencement date or last increase date where those particulars are required.
• A mid-fixed-term increase is not authorised by a clear term stating the amount or calculation.
• The increase is said to cover compliance with minimum housing standards.
• The increase relates to approval to keep a pet or the right to keep a working dog.

An unlawful-frequency issue and an excessive-amount issue are different. A within-12-month increase may be an alleged offence that the RTA can investigate. A compliant annual increase may still be reduced or set aside by QCAT if it is excessive on the evidence.

There is no general percentage cap, but the amount can be excessive

Queensland's standard private-rental rules limit frequency, not every increase to a fixed dollar or percentage. To assess excessiveness, QCAT must consider matters including:

• the range of rents usually charged for comparable premises;
• the proposed rent compared with the current rent;
• the property's state of repair;
• the term of the tenancy;
• the period since the previous increase; and
• anything else QCAT considers relevant.

The Act also directs attention to repairs or maintenance where a proposed increase relates to minimum housing standards, and to pet approval or a working dog where relevant. Importantly, section 91 says an increase is payable only if it does not relate to compliance with prescribed minimum housing standards or keeping a pet or working dog.

Build a fair comparison, not a pile of screenshots

Choose genuinely comparable properties. Record the address or suburb, date advertised, weekly asking rent, bedrooms, bathrooms, parking, property type, size where known, air-conditioning, outdoor space, furnishing and overall repair. Save the full listing as well as a screenshot because online advertisements disappear.

Include evidence about your own property: unresolved repair requests, condition photographs, missing facilities and any material disadvantage compared with the listings. Avoid cherry-picking only the cheapest advertisements; a balanced set is more credible.

How to negotiate without losing your deadline

Write calmly and make a specific offer. Explain any validity problem separately from your view that the amount is excessive. Attach a concise comparison table and propose a dollar amount or staged outcome.

“I received the proposed increase on [date]. I am concerned that the amount is excessive compared with the attached similar properties and the current condition of the premises. I propose rent of $[amount] from [date]. This request does not waive my rights or extend any application deadline.”

Continue paying the amount legally due. Do not simply stop paying the disputed portion without an agreement or order; rent arrears can create a separate breach. QCAT can make an interim order about payment of the proposed increase while deciding an application.

RTA dispute resolution and QCAT pathways

Rent-increase disputes are generally dealt with as non-urgent tenancy disputes. The RTA provides free, impartial conciliation through its online service or Dispute resolution request (Form 16). A conciliator helps negotiate but cannot decide the case. If it remains unresolved, the RTA may issue a Notice of Unresolved Dispute for a QCAT application.

Existing agreement increase notice

For a notice under an existing agreement, section 92 sets a 30-day limit after the tenant receives the notice. If the agreement is fixed-term, the application must also be made before the term ends. The RTA's current guidance directs tenants to dispute resolution and then QCAT. Because the statutory clock is short, lodge promptly and check with the RTA or QCAT how to preserve the deadline if conciliation is not completed.

Increase in a signed renewal agreement

For a significant change from an existing agreement to a new agreement, the tenant generally must sign the new agreement first and lodge the challenge within 30 days after entering into it. The tribunal may reduce the rent and treat the agreement as altered.

What QCAT can order

For an existing-agreement notice, QCAT may reduce the proposed increase by a stated amount or set it aside. For a renewal's significant change, it may reduce the rent. File the current QCAT residential tenancy application, attach the required RTA notice and evidence, and follow the current fee and service instructions.

Special situations

Retaliatory increase

If a rent increase is used to intimidate or punish a tenant for asserting rights, it may be retaliatory action. The RTA says a tenant who reasonably believes this occurred can make an urgent QCAT application within one month of becoming aware of the action. This is a different ground from “the rent is too high”, and evidence linking the increase to the asserted right matters.

Owner undue hardship

An owner who reasonably believes the 12-month limit would cause undue hardship may apply for a tribunal order allowing an earlier increase. In deciding, QCAT must consider the tenant's representations about affordability and ability to continue paying.

Bond increase

A rent increase does not automatically permit an immediate bond increase. The RTA states that the bond may be increased if at least 11 months have passed since the last bond increase or the tenancy began. The tenant must receive at least one month's notice, and the extra bond must generally be lodged with the RTA. For a general tenancy, the maximum bond is generally four weeks' rent regardless of weekly rent.

Rent-increase response checklist

The bottom line

Check timing and procedure before arguing about price. The strongest response identifies the last premises-wide increase date, preserves the short challenge deadline and uses genuinely comparable rentals plus condition evidence to propose a realistic outcome.
