2025 Australia Rent Increase Limits: State-by-State Rules & How Much Your Landlord Can Raise
In 2025, renters across Australia are facing higher living costs and a tight rental market. Many tenants are suddenly told their rent will go up, but they are not sure whether the increase is legal or reasonable. The rules are different in each state and territory, which means your rights depend heavily on where you live. If you do not understand the rent increase limits, you could end up paying more than you have to – or miss the chance to challenge an unfair rise. This guide explains the key 2025 rules, state by state, and what you can do if you think your landlord is asking for too much.
1. How Rent Increases Work in Australia in 2025
Australia does not have a single national rent cap. Instead, each state and territory has its own residential tenancy laws that cover:
- How often rent can be increased
- What notice your landlord must give you
- How you can challenge a rent increase you believe is excessive
In most parts of Australia, there is no strict percentage limit (for example, “no more than 5% per year”), but landlords must still keep rent at a level that is not excessive compared with similar properties in the area. Tribunals can order a lower rent if the increase is judged to be unreasonable.
2. State-by-State Rent Increase Rules for 2025
Below is a general overview of how rent increases work in each state and territory as of 2025. Always check your local tenancy authority for the most up-to-date rules before taking action.
2.1 New South Wales (NSW)
- Frequency: For periodic agreements, rent can usually be increased only once every 12 months.
- Notice: Landlords must give at least 60 days’ written notice of a rent increase.
- Limit: No fixed percentage cap, but tenants can apply to the NSW Civil and Administrative Tribunal (NCAT) if the increase seems excessive compared with similar properties.
2.2 Victoria (VIC)
- Frequency: For most residential agreements, rent increases are limited to once every 12 months.
- Notice: At least 60 days’ written notice is required, stating the new amount and the date it will start.
- Limit: No strict percentage cap, but tenants can ask Consumer Affairs Victoria or apply to VCAT to review an increase that appears unreasonable.
2.3 Queensland (QLD)
- Frequency: Rent can generally only be increased once every 12 months for the same tenancy.
- Notice: Landlords must provide at least 2 months’ written notice for periodic agreements.
- Limit: Again, no fixed percentage, but an increase must be “market rent” and can be challenged through the Residential Tenancies Authority (RTA) dispute process.
2.4 Western Australia (WA)
- Frequency: Rent increases usually cannot occur more often than every 6 months, and only if the agreement allows for it.
- Notice: At least 60 days’ written notice of the increase.
- Limit: No percentage cap. Tenants may apply to the Magistrates Court if the increase is excessive relative to similar properties.
2.5 South Australia (SA)
- Frequency: Rent can generally be increased once every 12 months during a tenancy.
- Notice: At least 60 days’ written notice is required.
- Limit: No fixed percentage cap, but the increase must be reasonable and consistent with market value. Disputes can go to the South Australian Civil and Administrative Tribunal (SACAT).
2.6 Tasmania (TAS)
- Frequency: Rent may normally be increased no more than once every 12 months.
- Notice: Landlords must give tenants at least 60 days’ written notice.
- Limit: No strict percentage limit, but tenants can challenge increases that are clearly excessive compared with similar rentals.
2.7 Australian Capital Territory (ACT)
- Frequency: Rent increases are generally limited to once every 12 months.
- Notice: At least 8 weeks’ written notice must be given.
- Limit: ACT has a more concrete benchmark: increases above a set “prescribed amount” (often linked to CPI, such as CPI plus a small percentage) can be challenged as excessive.
2.8 Northern Territory (NT)
- Frequency: Rent can usually be increased only if the agreement allows it, and not more often than every 6 months.
- Notice: At least 30 days’ written notice of any increase.
- Limit: No fixed cap, but tenants can apply to the Northern Territory Civil and Administrative Tribunal (NTCAT) if the increase is unreasonable.
3. How Much Can Your Landlord Actually Raise the Rent?
Because most states do not have a fixed percentage cap, the real question is whether the new rent still reflects market value. Tribunals will often look at:
- Recent rent for similar properties in the same area
- Property condition and included features
- Any improvements or renovations made by the landlord
- How long it has been since the last increase
As a rough guide, moderate increases that track local market trends and inflation are more likely to be accepted, while sudden jumps far above comparable rentals may be reduced if you challenge them.
4. What to Do If You Think the Increase Is Too High
If you believe your 2025 rent increase is excessive, do not ignore it. Instead:
- Check the official rules for your state or territory.
- Compare your new rent with similar properties on local rental websites.
- Talk to your landlord or agent and ask how they calculated the new amount.
- Contact your local tenancy advice service for free guidance.
- Apply to the relevant tribunal within the required time limit if you want a formal review.
Conclusion: Know Your Rights Before You Agree to a 2025 Rent Rise
In a tough rental market, it can feel like you have no choice but to accept any increase your landlord proposes. However, Australian tenancy laws still give you clear rights around how often rent can go up, how much notice you must get, and when you can challenge an increase as excessive. Before you sign a new agreement or accept a higher rent in 2025, take a moment to check the rules for your state, compare local prices, and get advice if something does not look fair. Knowing your rights could save you thousands of dollars over the life of your tenancy.
Quick Checklist for Tenants

- Has it been at least 6 or 12 months since the last increase (depending on your state)?
- Is the new rent similar to other rentals in your suburb?
- Have you checked your state or territory tenancy website?
- Do you still have time to apply to the tribunal if needed?
