Understanding Rent Increases in Queensland: What’s Legal, What’s Fair, and What Can Be Disputed

Rent increases are one of the most common sources of confusion and dispute in residential tenancies across Queensland. With recent rental reforms now in place, it is essential for both landlords and tenants to understand what is lawful, what is considered reasonable, and when a rent increase can be challenged.

A clear understanding of the legislation, combined with open communication, helps avoid disputes and supports fair outcomes for all parties.

How Often Can Rent Be Increased in Queensland?

In Queensland, rent can only be increased once every 12 months per property.

This rule applies regardless of whether:

  • The same tenant remains in the property, or
  • A new tenancy agreement is entered into with a different tenant

The 12-month period runs from the date the last rent increase took effect for the property, not from the start date of the current tenancy.

Any rent increase issued within 12 months of the previous increase is unlawful.

Rent Increases During Fixed-Term Agreements

Rent cannot be increased during a fixed-term tenancy unless the tenancy agreement specifically allows for it.

For a rent increase to occur during a fixed term:

  • The agreement must include a rent increase clause, and
  • The clause must clearly state how the increase is calculated (for example, a fixed dollar amount or a clear percentage)

If there is no valid rent increase clause, the rent must remain unchanged for the duration of the fixed term.

Notice Requirements for Rent Increases in Queensland

For a rent increase to be valid, Queensland legislation requires strict notice and documentation requirements to be met.

The legal requirements are:

  • A minimum of two months’ written notice must be given to the tenant

The notice must clearly state:

  • The current rent amount
  • The new rent amount
  • The date the increase takes effect

A rent increase may be invalid if:

  • The required notice period is not provided
  • The increase breaches the 12-month rule
  • The notice does not clearly state the required information

Verbal advice, informal emails, or general letters do not meet legislative requirements on their own.

What Is Considered a Fair Rent Increase?

While Queensland legislation does not set a maximum dollar amount or percentage for rent increases, it does require increases to be reasonable and reflective of the current market.

Factors commonly considered when assessing fairness include:

  • Market rent for comparable properties in the same area
  • The condition of the property
  • Any improvements or upgrades completed
  • Changes to facilities or services
  • The timing of the increase relative to market conditions

A rent increase should be supported by objective market evidence such as a rental CMA (comparative market appraisal) rather than applied without justification

When Can a Rent Increase Be Disputed?

Tenants in Queensland have the right to dispute a rent increase if they believe it is excessive.

The dispute process generally follows three steps:

  1. Raise concerns directly with the property manager or landlord, supported by evidence of why you believe it is excessive

  2. Apply to the Residential Tenancies Authority for free dispute resolution if the matter cannot be resolved

  3. Apply to QCAT if dispute resolution is unsuccessful

When assessing whether an increase is excessive, QCAT may consider:

  • Comparable rental properties
  • The property’s condition
  • Previous rent amounts
  • Any changes to the property or tenancy

The Importance of 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
  • Reduce disputes and vacancy risk
  • Ensure compliance with Queensland tenancy laws

A transparent and informed approach benefits both parties.

Final Thoughts

In Queensland, rent increases must be:

  • Limited to once every 12 months per property
  • Issued with at least two months’ written notice
  • Supported by market evidence and clear communication

Understanding these requirements helps landlords protect their investment while ensuring tenants are treated fairly and lawfully.
