Rent increases in NSW are allowed but must follow strict rules. Landlords need to give 60 days’ written notice for periodic tenancies, and fixed‑term increases require a clear lease method. Tenants can challenge excessive rent increases at NCAT and should keep paying undisputed rent. Urgent repairs and property condition can influence outcomes.
Key Legal Points
- Rent increases are regulated adjustments to residential rent in NSW
- Valid notices must be written, specify start date, and give 60 days’ notice
- Fixed‑term increases need a lease clause with amount or calculation method
- NCAT can reduce or set aside excessive or non‑compliant rent increases
- Keep paying undisputed rent while challenging an increase at NCAT
- Unaddressed urgent repairs can support rent reduction or dispute outcomes
- Invalid notices bar retrospective recovery of higher rent
Rent increases are adjustments to the price a tenant pays to occupy a residential property in New South Wales. They are regulated, require proper notice, and can be challenged if excessive or non‑compliant. In NSW, rent increases sit within a wider framework that also covers bond disputes, eviction notices, and urgent repairs for residential tenancy arrangements.
Understanding Rent Increases and Tenant Rights in NSW
Legal Framework
NSW residential tenancy law is primarily set out in the Residential Tenancies Act 2010 (NSW) and associated regulations. It sets notice periods, limits how often rent increases can occur in periodic agreements, and outlines remedies.
Key protections apply whether the tenancy is fixed term or periodic. The tribunal can set aside or reduce rent increases that are excessive, improper, or not validly notified.
Key Definitions
- Rent increase notice means a written notice specifying the new rent and the start date
- Fixed‑term agreement means a lease with an end date, often 6 or 12 months
- Periodic agreement means a continuing tenancy without an end date
- NCAT application means a tenant’s claim to the NSW Civil and Administrative Tribunal

Requirements and Procedures for Lawful Rent Increases
Statutory Requirements
For periodic agreements, rent increases require at least 60 days’ written notice. For fixed‑term agreements of 2 years or less, rent can only be increased if the lease specifies the amount or calculation method.
In real scenarios, we see disputes when notices are verbal, dates are unclear, or the lease lacks a valid formula for mid‑term rent increases.
Valid Notice Content
- State the proposed new rent and the exact start date
- Be in writing and properly served under the agreement
- Provide 60 days’ notice for periodic agreements
Challenging Excessive Increases
Tenants can apply to NCAT to review rent increases they consider excessive. The tribunal assesses market rent, property condition, amenities, location, and comparable listings.

Rent Increases, Bond Disputes, Eviction Notices, and Repairs
Bond and Rent Changes
Rent increases do not automatically justify demanding extra bond during a fixed term unless the agreement allows it. At the end of the tenancy, bond disputes often arise over arrears following a disputed increase.
Keep records of all notices and payments to protect your position if a refund claim is contested.
Eviction Notices and Non‑payment
Where a tenant refuses to pay an asserted increase that is not validly notified, arrears may be disputed. If an eviction notice follows, NCAT can examine whether the rent increase was lawful before considering termination.
In practice, a negotiated rent review can avoid needless termination applications and costs.
Urgent Repairs and Rent
Urgent repairs like hot water, dangerous electrical faults, or serious leaks should be addressed quickly. Significant unremedied issues may support a rent reduction or challenge to rent increases if the property’s condition has deteriorated.
Document faults, communications, and invoices to strengthen any claim for compensation or rent adjustment.
Process / Steps to Manage Rent Increases
Step‑by‑step for Tenants
- Check your agreement for any valid rent review clause
- Verify that you received 60 days’ written notice, with a clear start date
- Compare market rent using recent listings and similar properties
- Raise concerns in writing and request evidence supporting the increase
- If unresolved, apply to NCAT before or shortly after the increase takes effect
Step‑by‑step for Landlords/agents
- Confirm the agreement permits rent increases during the term, if applicable
- Serve a compliant written notice, observing the 60‑day timeline
- Keep market evidence and property condition records
- Consider negotiating staged increases to reduce dispute risk
- Prepare for NCAT by compiling comparisons and maintenance history
Common Mistakes in NSW Rent Increases
What to Avoid
- Issuing verbal or unclear notices without specific dates
- Trying to increase rent mid‑term without a written formula
- Ignoring property defects while demanding higher rent
- Conflating a disputed increase with immediate arrears and issuing eviction notices
Real‑world Examples
We often see a 15 percent increase notice served by email without a start date, which is defective. Another common pattern includes increases applied during fixed terms with no formula set out, leading to NCAT orders invalidating the change.
Deadlines, Limits, and Costs
Time Factors
Minimum notice for periodic rent increases is 60 days. NCAT applications challenging increases should be made promptly, often within the notice period or soon after the increase commences.
Keep an eye on prescribed timeframes for any termination or bond applications that may follow.
Financial Considerations
NCAT filing fees are modest and may be reduced for concession holders. Costs are usually each party’s own, with limited circumstances for costs orders.
Staged rent increases can ease pressure on tenants and reduce default risk, protecting both sides.
Consequences of Non‑compliance
What Happens if the Notice is Invalid
An invalid notice means the tenant is not required to pay the higher amount. Retrospective rent recovery usually fails where the notice did not comply.
NCAT can set aside or vary rent increases and may make ancillary orders, including refunds or rent setting for a period.
Compliance Requirements
Parties must preserve evidence, communicate in writing, and comply with service rules. Landlords should address urgent repairs promptly to avoid rent reduction claims and disputes.
Referencing the Act is essential. See Residential Tenancies Act 2010 (NSW) sections 41 and 44 regarding notice and excessive increases.
How to Resolve / Next Steps
Practical Guidance
Start with a written discussion anchored to market data and property condition. If you cannot agree, apply to NCAT and continue paying the undisputed rent while the matter is determined.
Where other disputes exist, such as urgent repairs or bond disputes, consider resolving them holistically to close off multiple issues at once.
Recommended Actions
- Audit your lease terms and prior notices before responding
- Gather comparable rentals, inspection reports, and repair records
- File an NCAT application if negotiation fails or deadlines loom
Negotiation and Mediation Options
Using Assisted Resolution
Many rent increases disputes settle with a clear timetable, staged adjustments, or temporary rent reductions for repairs. Mediation can save costs and preserve tenancies.
Learn more about structured dispute resolution in Commercial Mediation In Australia, which outlines practical negotiation dynamics relevant to residential contexts.
Examples from Practice
For instance, a 10 percent increase paired with landlord‑funded appliance replacement and minor repairs often resolves conflict. Another example is deferring part of a rent rise until after water ingress works are completed.

Frequently Asked Questions
How much notice is required for rent increases in NSW?
For periodic tenancies, landlords must give at least 60 days’ written notice specifying the new rent and start date. In fixed terms of 2 years or less, rent can only increase if the agreement allows it and sets out the amount or a clear calculation method.
Can I challenge an excessive rent increase at NCAT?
Yes. You can apply to NCAT to review an increase you consider excessive. The tribunal looks at market comparisons, property condition, amenities, location, and whether the notice was valid. File promptly and keep paying the undisputed portion of rent during the dispute.
Does a rent increase allow the landlord to raise the bond?
Generally not during a fixed term unless the lease permits it. At the end of a tenancy, bond disputes often revolve around arrears following a disputed increase. Maintain records of notices and payments to support or defend any bond refund claim.
What if repairs are outstanding when the landlord issues a rent increase?
Urgent repairs should be addressed quickly. Significant unrectified defects may support seeking a rent reduction or challenging an increase. Keep evidence, such as photos, trades invoices, and correspondence, to support any compensation or rent adjustment claim at NCAT.
What happens if the rent increase notice is invalid?
If the notice is invalid, you are not required to pay the higher amount. NCAT can set aside or vary the increase. Landlords usually cannot recover increased rent retrospectively if statutory notice requirements were not met. Continue paying the undisputed rent while resolving the issue.
Can I be evicted for not paying a disputed rent increase?
Eviction depends on whether the increase was lawful and properly notified. If the increase is disputed, NCAT can assess validity before considering termination. Tenants should keep paying the undisputed rent and apply to NCAT promptly if negotiations fail.
