Understanding rent increases in Australia
A percentage rent increase is applied to your current rent to give the new amount. Even a modest percentage adds up over a year, this shows both the new per-period rent and the extra annual cost.
Rent increase rules differ by state. There are usually limits on how often rent can rise (commonly once every 12 months) and minimum notice periods (often 60 days). If an increase seems excessive, most states let tenants challenge it at the tribunal.
