Leases don’t always run on a fixed end date. Many tenancies move to a rolling or “periodic” arrangement, and that’s often when questions about rent increases pop up. If you’re running a small business from leased premises, or you’re managing an investment property, understanding when and how rent can be increased on a periodic lease is essential to staying compliant and avoiding disputes.
Australia’s rules aren’t one‑size‑fits‑all. The details differ between states and territories, and residential tenancies are regulated very differently to commercial and retail leases. The good news is that with the right process (and some planning), you can manage periodic rent reviews lawfully and fairly.
In this guide, we’ll explain how periodic lease rent increases work in Australia, highlight the key differences between residential and commercial arrangements, and outline practical steps for both landlords and tenants. We’ll also flag common traps and where tailored legal advice can help.
What Is a Periodic Lease (And When Does It Happen)?
A periodic lease (sometimes called a periodic tenancy or “holding over”) is an ongoing arrangement that continues in repeating periods (for example, month‑to‑month or week‑to‑week). It can occur in two common ways:
- Residential tenancies: By statute, most fixed‑term residential leases automatically roll over to a periodic tenancy when the end date passes and the tenant stays on with the landlord’s consent.
- Commercial/retail leases: If a tenant remains in occupation after the fixed term ends and the landlord accepts rent, the lease may “hold over” under its terms or at law. Many commercial leases include a holding‑over clause that continues the lease on a monthly basis.
Importantly, you don’t usually “sign a periodic lease” for residential tenancies - it happens by operation of your state or territory’s legislation. In commercial settings, whether you’re holding over and on what terms will depend on your original lease and any agreed extension or variation.
How Do Rent Increases Work On Periodic Leases?
The rules depend on whether the tenancy is residential or commercial/retail, and which state or territory applies. Think of the framework in three parts: notice, frequency, and fairness.
Residential Periodic Leases
Across Australia, residential rent increases on a periodic tenancy are allowed, but they must follow statutory requirements. These commonly include:
- Written notice: You must receive a written notice that clearly states the new rent and the effective date. Method of service matters (post vs email vs hand delivery) because it can add “deemed” days to the notice period.
- Minimum lead time: The minimum notice period varies by jurisdiction. Many states require around 60 days’ notice; the ACT uses 8 weeks, while the Northern Territory requires a shorter period (30 days). Always check your local Act and regulations.
- Limits on frequency: Most jurisdictions cap increases to once every 12 months, calculated from the date of the last increase. Some states differ - for example, Western Australia and the Northern Territory use a six‑month minimum interval.
- Right to challenge: Tenants can dispute an “excessive” increase in a tribunal (for example, NCAT in NSW, VCAT in Victoria, QCAT in Queensland or SACAT in South Australia). The tribunal will consider market comparables, property condition and recent improvements.
Because these rules are set by each state/territory’s residential tenancies legislation, avoid relying on generic statements. If you manage properties across borders, set a compliance checklist by jurisdiction so your notices always meet the correct lead time and frequency caps.
Commercial And Retail Periodic Leases
Commercial leasing is contract‑driven. Rent review mechanisms (CPI, fixed percentage, or market review) are usually set out in the lease. If the lease holds over after the term, what happens to rent depends on the holding‑over clause or any extension agreement between the parties.
- If your lease says that rent during holding over continues on the same terms (including scheduled reviews), that clause usually governs.
- If there’s no clear clause, landlords and tenants often negotiate a short extension or a new lease. In some states, retail leasing laws regulate how and when market rent reviews can occur.
If you’re unsure how your holding‑over clause operates or whether a market increase is permitted, it’s wise to obtain a lease review before issuing notices or agreeing new terms.
Periodic Vs Fixed Term: What’s Different About Rent Increases?
It helps to separate two scenarios: what can happen during a fixed term, and what can happen once the lease becomes periodic.
During A Fixed Term
- Residential: A rent increase during a fixed term is only valid if your agreement clearly states how the increase will be calculated and when it will occur. Open‑ended or vague clauses can be unenforceable.
- Commercial/retail: Rent reviews typically follow the formula in the lease (CPI, fixed percentage, or market at option). Retail leasing legislation in some states restricts certain review combinations and how a market review is conducted.
After The Lease Becomes Periodic
- Residential: The statutory periodic rules take over (minimum notice, limits on frequency, and a right to challenge). Even if your fixed‑term agreement didn’t permit increases, the law may allow increases on a periodic tenancy if the proper process is followed.
- Commercial/retail: The lease terms (including any holding‑over clause) remain central. If there’s no clear mechanism, the parties should negotiate and document the new arrangements - for example, via an extension of lease - to avoid uncertainty.
For NSW businesses specifically, it’s common to look at whether a rent review is permitted while holding over and whether retail leasing rules affect timing or method.

What Notices And Timeframes Apply? (By Jurisdiction)
Notice periods and frequency caps differ by state and territory, particularly for residential tenancies. The following points are a practical guide - always cross‑check the current legislation in your jurisdiction before acting.
- New South Wales (residential): Written notice with a minimum lead time (commonly 60 days) and not more than once every 12 months on a periodic tenancy. Retail/commercial: governed by the lease; retail leasing rules add extra requirements. See Retail Leases Act (NSW) for retail premises.
- Victoria (residential): Written notice (commonly 60 days) and generally a 12‑month minimum between increases on periodic tenancies. Retail/commercial: lease controls increases; retail leasing legislation regulates market reviews.
- Queensland (residential): Written notice (minimum 2 months for periodic tenancies) and at least 12 months between increases. Retail/commercial: check the lease; retail shop leases legislation may apply.
- Australian Capital Territory (residential): 8 weeks’ written notice and limits tied to market and CPI for “standard” increases, unless justified. Retail/commercial: lease rules apply; statutory provisions may affect market reviews.
- South Australia (residential): Written notice (commonly 60 days). Frequency limits apply. Commercial: lease terms govern; consider documenting any holding over.
- Western Australia (residential): Written notice (commonly 60 days). Frequency minimum is typically six months. Commercial/retail: lease‑based with retail legislation overlay for eligible shops.
- Tasmania (residential): Written notice (commonly 60 days) and a 12‑month minimum interval. Commercial: lease governs; consider an extension or new lease when holding over.
- Northern Territory (residential): Written notice (30 days) and a six‑month minimum between increases. Commercial: lease determines the position.
If the tenancy is commercial or retail, the notice period and method will nearly always come from the lease language. If holding over was not contemplated, seek advice and agree a short‑form variation before relying on a rent increase to avoid disputes about enforceability.
How To Increase Rent Lawfully (And How To Challenge An Increase)
Whether you’re a landlord or a tenant, the process matters. A valid notice issued at the wrong time - or without the required content - can be ineffective.
Landlords: Practical Steps To Issue A Valid Increase
- Confirm the governing framework. Is the tenancy residential under the local Residential Tenancies Act, or is it a commercial or retail lease? The process is different.
- Check frequency limits. Look at the date of the last increase and your jurisdiction’s minimum interval (12 months in many states; six months in some).
- Prepare a compliant notice. Include the current rent, the new amount, and the exact date the increase takes effect. Use the correct service method and allow extra time if posting.
- Cross‑check the lease. For commercial/retail premises, make sure the method (CPI, fixed, market) and timing comply with the rent review clause and any holding‑over provision.
- Keep it reasonable. A sharp jump above market rate invites a tribunal challenge (residential) or a relationship breakdown (commercial). Evidence of comparable rents helps.
- Document the position. If the commercial lease term has expired, consider a short extension or a deed to record the holding over and rent while you negotiate a new lease.
Tenants: Your Options If You Receive A Rent Increase
- Check form and timing. Was the correct notice given with the required lead time? If not, the increase may not be effective yet.
- Compare to market. Gather rental evidence for similar properties in your area. This is crucial if you want to challenge a residential increase as excessive.
- Act within deadlines. Tribunal applications (residential) often need to be lodged before the increase takes effect. Don’t wait until after the effective date.
- Negotiate early. For commercial/retail premises, start the conversation early. If you’re holding over, consider negotiating a short extension or a new term with agreed increases.
- Consider your broader rights. In some situations, ending the tenancy may be a commercial decision if the increase can’t be justified. In NSW, if you’re weighing up your position near the end of a term, this guide to lease termination notices explains key steps.
If you’re unsure, getting a quick, independent view on your lease and the proposed increase can save time and prevent a dispute. A focused review by a commercial lease lawyer is often the fastest way to confirm your options.
Common Mistakes To Avoid
Periodic rent increases are straightforward when you follow the rules - and risky when you don’t. These are the mistakes we see most often.
- Using the wrong notice period. Don’t rely on generic rules; each state and territory has its own timing and service requirements for residential increases.
- Missing the frequency limit. A 12‑month cap applies in many jurisdictions; some use six months. Issuing a notice too soon can invalidate the increase.
- Assuming a commercial increase applies automatically in holding over. If your lease doesn’t clearly allow it, negotiate and document an extension or variation.
- Mixing review methods improperly (commercial/retail). Some retail laws restrict combinations (e.g. not mixing CPI and market in the same review). In NSW, review your position against the Retail Leases Act before proceeding.
- Skipping market evidence. For residential disputes, comparable rents matter. For commercial market reviews, third‑party valuation may be required by the lease.
- Letting a dispute drift. If you need tribunal relief (residential), there’s usually a short window to apply. For commercial disputes, consider prompt negotiation or a documented variation.
What Documents And Clauses Matter?
For residential periodic tenancies, the law supplies most of the rules - you won’t typically sign a new “periodic agreement.” However, documents still matter, particularly in commercial and retail settings.
- Rent Review Clause (Commercial/Retail): Sets the mechanism (CPI, fixed, market) and timing. During holding over, the lease’s holding‑over clause often dictates whether reviews continue.
- Holding‑Over/Extension Of Lease: A short extension or variation can clarify rent, the review method and notice while you negotiate a new term.
- Market Review Procedure: Many leases prescribe how a market review happens (e.g. independent valuer appointment, timetables and dispute resolution).
- Disclosure (Retail): Retail leasing regimes impose disclosure obligations. If your premises are a “retail shop,” check statutory rules before changing rent.
- Variation Or Amendment: If your rent review clause is unclear (or you’re moving from CPI to market), a short‑form lease amendment can prevent arguments later.
If you’re operating in NSW, this practical overview of commercial rent increases explains how CPI, fixed and market reviews commonly play out - especially during renewals and holding over.
Residential Or Commercial: When Should You Get Advice?
Many periodic increases are handled smoothly. However, the cost of getting it wrong can outweigh the cost of a quick legal check. It’s particularly worth getting advice if:
- You manage properties in multiple states and want a compliant notice template for each jurisdiction.
- Your commercial lease is holding over and the rent review clause doesn’t clearly address what happens next.
- You need to run a market review in a retail lease and aren’t sure how the process or retail legislation applies.
- You’re considering refusing a proposed commercial increase and want options (for example, negotiating a staged increase or a rent‑free period tied to a new term).
In many cases, a short consultation and targeted drafting (for example, a tailored extension letter or a variation deed) will resolve uncertainty quickly and protect the relationship.
Key Takeaways
- Periodic lease rent increases are lawful in Australia, but the process depends on whether the tenancy is residential or commercial/retail and which state or territory applies.
- Residential periodic increases require a compliant written notice, a minimum lead time and compliance with frequency limits (often 12 months; some jurisdictions use six months).
- Commercial and retail rent increases are largely governed by the lease; during holding over, look to the holding‑over clause or document a short extension or variation.
- Tribunals can review residential increases for excessiveness; market evidence and correct timing are crucial. Commercial disputes usually turn on the lease and any retail legislation.
- Before acting, check your jurisdiction’s current rules and your lease wording. Where terms are unclear, a short lease review or amendment can prevent costly disputes.
- If you operate in NSW, be mindful of retail leasing rules and typical rent review mechanisms - resources on the Retail Leases Act and commercial increases are a helpful starting point.
