Challenging a Rent Increase in Australia

Australian tenancy law gives tenants ways to question some rent increases, but rules differ by state and territory. RentWize helps you record the notice, dates, rent history, and response timeline so you can review the facts before deciding what to do next.

What Makes a Rent Increase Unlawful?

A rent increase may be unlawful or challengeable if:

• Insufficient notice — your landlord didn't give you enough written notice
• Too frequent — the increase comes too soon after the last one
• Excessive amount — the increase is unreasonably above market rent (some states allow this to be disputed)

Minimum notice periods and frequency rules vary by state. RentWize can surface state-aware prompts when you log an increase, but you should verify current rules with your state authority before relying on them.

How to Log a Rent Increase

1. Open your property in RentWize
2. Tap Rent History → Log Increase
3. Enter the new rent amount and the effective date
4. Enter the date you received written notice
5. Review any state-aware prompts and compare them with the current rules for your state or territory

If the increase appears to need review, keep the notice, dates, and any explanation together so you can check the issue before taking action.

Challenging a Non-Compliant Increase

If RentWize flags a problem:

1. Review the notice, dates, and rent history.
2. Save any comparison notes or communication with your landlord or agent.
3. Consider contacting your state tenancy authority, tenants' union, community legal centre, or qualified adviser before sending a formal response.
4. Keep any response and follow-up in the same property timeline.

Going to Tribunal

If the dispute is not resolved, RentWize Pro can export a structured bundle with your rent history, notice, and correspondence for review. See Exporting a Tribunal Bundle for how this works.
