2025 Australia Rent Increase Limits: How Much Landlords Can Legally Raise Your Rent
With Australia’s rental market still experiencing high demand and limited supply in 2025, many tenants are facing steep rent increase notices.
However, each state and territory has clear rules around how often rent can increase, how much landlords can raise it, and the
1. Australia’s 2025 Rent Increase Rules: The Basics
Across most states in 2025, rent increases must meet three criteria:
- They must be “reasonable” compared to market conditions
- They must follow the allowed frequency rules (usually once every 12 months)
- Proper written notice must be provided with specific timelines
While Australia does not have a national rent cap, every state has its own legal restrictions.
2. State-by-State Rent Increase Limits for 2025
• New South Wales (NSW)
- Frequency: Once every 12 months for ongoing leases
- Notice: 60 days written notice
- Limit: No fixed cap, but must be “reasonable”
• Victoria (VIC)
- Frequency: Once every 12 months
- Notice: 60 days
- Limit: No percentage cap, but tenants can challenge excessive increases at VCAT
• Queensland (QLD)
- Frequency: Once every 12 months
- Notice: 2 months
- Limit: Must be tied to the same tenant, not the property (closing old loopholes)
• Western Australia (WA)
- Frequency: Every 6 months for periodic leases
- Notice: 60 days
- Limit: No cap, but increases must follow lease terms
• South Australia (SA)
- Frequency: Once every 12 months
- Notice: 60 days
• ACT
- Limit: Market rent increases above CPI + 10% can be challenged
- Strongest rent increase protections in Australia
The ACT remains the closest to having a formal “rent cap” system in 2025.
3. What Counts as an Illegal Rent Increase?
A rent increase may be unlawful if:
- No proper written notice was given
- The increase is issued too frequently
- The amount is significantly above market rate
- The landlord is retaliating for maintenance requests
- The landlord failed to follow state tenancy procedures
Tenants can challenge illegal or unreasonable increases through their state tribunal (NCAT, VCAT, QCAT, SACAT, etc.).
4. How to Dispute an Unfair Rent Increase (Fast Method)
1 — Request justification in writing
Landlords should explain why the increase is necessary.
2 — Check local market prices
Use realestate.com.au and Domain listings to compare similar properties.
3 — Apply to your state tribunal
Tribunals often reduce or reject increases that exceed fair market conditions.
4 — Ask for a negotiation
Many landlords accept a smaller increase rather than risk a tribunal ruling.
Conclusion: Know Your Rights Before Accepting Any Rent Increase
In 2025, Australia’s rental laws give tenants stronger protection against excessive or unreasonable rent hikes. By understanding the legal limits, required notice periods, and how to dispute unlawful increases, you can avoid being overcharged and ensure your tenancy remains secure. Always check your state’s rules, gather market comparisons, and be prepared to challenge increases through a tribunal if needed.
