Rent increases are one of the most heavily regulated parts of an Australian residential tenancy, and the rules are set by state and territory legislation rather than left to the landlord. That means a clause in your agreement that allows the landlord to raise the rent more often, or with less notice, than the law permits is simply unenforceable. But tenants who do not know the statutory limits often pay increases they could lawfully challenge, so the rent increase clause is worth reading carefully before you sign.
What is a Rent Increase Rules?
A rent increase clause sets out when and how the landlord can raise the rent during a tenancy. Each Australian state and territory has its own Residential Tenancies Act that controls this: typically rent cannot be increased during a fixed term unless the agreement specifically allows it and states the amount or method, increases are limited to once in any 12-month period, and the landlord must give a minimum period of written notice — commonly 60 days. The clause in your agreement must operate within those statutory limits, and a tribunal can review an increase that is excessive.
Red flags to watch for
In most states rent can only rise during a fixed term if the agreement sets out the increase amount or a clear method of calculation; a clause allowing an unspecified increase is generally invalid.
If the clause allows less than the legislated notice — commonly 60 days — the shorter period is unenforceable and any increase served on it can be challenged.
Most jurisdictions cap rent increases at once per 12-month period; a clause permitting more frequent rises does not override the legislation.
An automatic indexation or market-review clause can produce large jumps; tenants should know they can apply to the tribunal if an increase is excessive.
A clause presenting an increase as final and non-negotiable can discourage tenants from exercising a genuine right to seek tribunal review.
Verbal notice, or notice that does not state the new amount and the date it takes effect, does not meet the legislative requirements.
Your legal rights
Residential rent increases in Australia are governed by the Residential Tenancies Act of each state and territory — for example the Residential Tenancies Act 2010 (NSW) and the Residential Tenancies Act 1997 (Vic). Common features across jurisdictions are that rent generally cannot be increased during a fixed term unless the agreement specifies the increase or the method of working it out, increases are limited to once in any 12-month period, and the landlord must give written notice of a minimum period — frequently 60 days — stating the new amount and the date it applies. If you believe an increase is excessive, you can apply to the relevant tribunal (such as NCAT, VCAT, QCAT, or the equivalent) to have it reviewed. The Australian Consumer Law also prohibits unfair terms in standard-form consumer contracts.
