Unreasonable Rent Increase? Your Right to Challenge and the Letter to Send

The notice arrived: rent up by $120 a week from next month. No explanation, no comparable evidence. You’re a good tenant who pays on time and looks after the place. In every Australian state and territory, rent increases must comply with strict notice, frequency and reasonableness rules — and a properly-drafted letter of demand is often the document that triggers a renegotiation.

The rules in your state

New South Wales: Residential Tenancies Act 2010 — minimum 60 days’ written notice; no more than once every 12 months in a periodic agreement; can be challenged at NCAT as “excessive”. Victoria: Residential Tenancies Act 1997 — 60 days, once per 12 months; VCAT review for excessive increases. Queensland: Residential Tenancies and Rooming Accommodation Act 2008 — 2 months’ notice; max once per 12 months; QCAT review. Western Australia: Residential Tenancies Act 1987 — 60 days; max once per 6 months in a periodic agreement; Magistrates Court review. South Australia: Residential Tenancies Act 1995 — 60 days; once per 12 months; SACAT excessive-rent review. Australian Capital Territory: Residential Tenancies Act 1997 — 8 weeks; presumed excessive if exceeds CPI by more than 110%; ACAT. Tasmania: Residential Tenancy Act 1997 — 60 days; once per 12 months; review by the Residential Tenancy Commissioner. Northern Territory: Residential Tenancies Act 1999 — 30 days; once per 6 months; NTCAT.

Common landlord defences and why they fail

“It’s market rate.” The landlord must produce comparable evidence; assertion is not proof. “Costs have gone up.” General cost increases don’t justify rent rises beyond what comparable properties achieve. “We can charge what we want.” False — every state has an excessive-rent jurisdiction. “If you don’t like it, leave.” Termination in retaliation for asserting tenancy rights is itself unlawful in most states.

What the document does

A Letter of Demand challenging a rent increase puts the landlord on formal notice that the increase is contested, identifies the procedural or reasonableness defects, and proposes either withdrawal of the increase or a negotiated lower amount. It also preserves your right to apply to the tribunal within the prescribed timeframe (typically 30 days from the notice).

What Claim Done delivers

For a flat fee, Claim Done drafts your Letter of Demand with the correct Act citations for your state, the procedural and reasonableness arguments, and a clear counter-proposal.

What happens after

A meaningful proportion of landlords either withdraw or negotiate down once they receive a properly-framed challenge — defending an excessive-rent application at tribunal is expensive and risks orders against them. If they refuse, you can apply to your state tribunal within the prescribed timeframe.
