How it works in South Australia
South Australia limits rent increases to once every 12 months, and since 1 March 2024 that limit applies even where both parties agree to an earlier rise. The landlord must give 60 days' written notice on the Consumer and Business Services form, specifying an effective date at least 60 days ahead and at least 12 months after the tenancy started or the last increase. There is no cap, but SACAT can review an increase a tenant considers excessive.
