Fixed-Term vs Periodic Agreements: Understanding Rental Contracts In Australia

Signing the right lease can make or break your plans - whether you’re securing a shopfront, a warehouse or office space, or looking for a bit of flexibility before you commit long term.

In Australia, most tenancies are either a fixed-term agreement or a periodic (rolling) agreement. Each option affects your security of tenure, how rent can change, how you can exit, and what happens at the end of the term.

In this guide, we’ll unpack the key differences between fixed-term and periodic agreements, highlight how state and territory rules can change what’s possible, and share practical tips to protect yourself before you sign. Our focus is on small business and retail leases, with brief notes for residential tenants where it helps with context.

Fixed-Term vs Periodic: What Do These Agreements Actually Mean?

What Is A Fixed-Term Agreement?

A fixed-term agreement sets a defined start and end date - for example, 6, 12 or 24 months (and often longer for commercial or retail leases). During that term, both parties are generally locked into the deal, unless the lease allows changes or a party has a legal ground to end it early.

• Security and planning: You know how long you have the space and what you’ll pay (subject to any rent review clause).
• Set end date: The lease finishes on a specified day unless you renew, extend or negotiate a new term.
• Early exit can be costly: Breaking a fixed term usually triggers break fees, make-good obligations, or other costs under the lease.

For business tenants investing in fit-out or location-specific goodwill, fixed terms often make sense. If you’re negotiating, have the document reviewed by a commercial lease lawyer so the term, options to renew, rent reviews and outgoings match your plans.

What Is A Periodic (Rolling) Agreement?

A periodic agreement continues from period to period - commonly month-to-month - without a set end date. The tenancy rolls on until one party validly ends it under the lease or applicable legislation.

• Flexibility: Either party can end the tenancy by giving the correct notice on a valid ground (see state-based rules below).
• No fixed end: You can keep occupying the premises while it suits both parties.
• Adjustments are easier: Rent or other terms can be reviewed in line with the lease and law, often with shorter lead time than on a fixed term.

Periodic agreements suit businesses in transition - for example, testing a location or waiting on a fit-out elsewhere. The trade-off is reduced certainty: the landlord may have pathways to end the tenancy sooner than you’d like.

Key Differences At A Glance

• End date: Fixed-term leases end on a set date; periodic leases continue until validly ended.
• Exit costs: Fixed-term exits often involve break fees, ongoing rent until re-letting, and make-good; periodic exits typically require the correct notice and compliance with any grounds requirements.
• Rent changes: On fixed terms, rent changes must be set out in a rent review clause. On periodic, rent can usually be adjusted in line with the lease, with required notice.
• Renewal: Fixed terms may include options to renew; periodic agreements don’t need renewal but can be ended on notice (subject to the rules where you operate).
• Holding over: If you stay after a fixed term expires, many commercial leases switch to month-to-month under the same terms. Check your lease’s “holding over” clause.

How Do These Leases End In Practice?

Ending A Fixed Term Early

Breaking a fixed term is usually harder and more expensive. Commercial leases commonly require you to:

• Pay a break fee or liquidated damages (if the lease allows early termination).
• Continue rent and outgoings until the premises are re-let (plus the landlord’s reasonable re-letting costs), if no contractual break right exists.
• Complete make-good and restoration obligations.

In limited situations (for example, a serious breach by the other party), termination rights may be available. Because the consequences can be significant, get tailored lease termination advice before taking steps.

Ending A Periodic Agreement

For periodic tenancies, the ending process is driven by the lease terms and state or territory legislation. Two important points:

• Notice periods vary: The required notice can differ by jurisdiction and the reason for termination.
• “No grounds” endings are restricted in some places: Some states and territories require prescribed grounds to end a periodic tenancy. Others allow “no reason” termination with a longer notice period, particularly in the residential context.

In short, don’t assume any landlord or tenant can end a periodic agreement “with simple notice everywhere.” The rules differ by jurisdiction and by lease type (commercial/retail vs residential). If in doubt, speak with a commercial lease lawyer before issuing or responding to a notice.

What Happens When A Fixed Term Ends?

At the end of a fixed term, one of three things usually happens:

1. You sign a new fixed-term lease (often with updated rent or conditions).
2. You vacate by the end date in line with the lease.
3. You “hold over” and the lease becomes periodic (commonly month-to-month) under the existing terms, if the lease allows holding over.

If you plan to renew, check any deadlines for exercising options and required notice periods. For NSW tenancies, our guide to lease renewal notice periods is a helpful starting point, and there’s also a QLD renewal overview for businesses operating in Queensland.

Can Rent Be Increased?

Rent reviews depend on the lease and the law in your state or territory:

• Fixed-term leases: Rent can increase only if there’s a rent review clause (for example, CPI, fixed percentage, or market review) and any statutory requirements are met.
• Periodic agreements: Rent can generally be adjusted in line with the lease and with the required written notice. Retail leases may have additional constraints and disclosure requirements.

If your premises is a retail shop, state-based retail leasing laws (such as the Retail Leases Act (NSW)) set minimum standards around disclosure, rent review transparency and outgoings. It’s worth getting a lease review before you commit so you know exactly how your rent will change over time.

Which Lease Type Fits Your Situation?

Business Tenants

Consider a fixed-term lease if you’re investing in:

• Fit-outs or specialist equipment that only works in the current premises.
• Building local goodwill that depends on the exact location.
• Financing arrangements that require a minimum term of occupancy.

A periodic lease can be attractive when you’re:

• Piloting a concept or testing a new area.
• Waiting on a future move, development approval or fit-out elsewhere.
• Prioritising flexibility over long-term certainty.

Whichever you choose, try to avoid open risk. Tighten the rent review mechanism, cap outgoings where possible, and be clear on make-good. A quick conversation with a commercial lease lawyer can help you spot red flags early.

Landlords

Fixed terms provide income certainty and can support your financing. Periodic arrangements allow earlier changes of strategy - for example, redeveloping or re-letting - subject to the applicable notice and grounds rules and any “holding over” provisions in the expired lease.

If re-taking possession is a priority at the end of a fixed term, understand the exact notice timing and method under your lease and any legislation. For NSW businesses, there are specific steps for a notice to vacate a commercial lease.

Residential Tenants (Brief Note)

Residential leasing is heavily regulated and rules differ across jurisdictions. Some states and territories restrict “no grounds” endings for periodic tenancies, while others allow them with longer notice. If your query is residential-specific, check your local residential tenancies legislation and official guidance for the most current rules where you live.

Rent Reviews, Options, Assignments And Holding Over

Rent Review Clauses

Commercial and retail leases should clearly set out when and how rent will rise. Common methods include CPI, fixed percentage increases or a market review at option time. Retail leasing legislation can limit certain mechanisms or the way they operate, so consistency and clarity are critical.

Options To Renew

Options give you the right (but not the obligation) to take a further fixed term on stated terms. Don’t miss the deadline: if you need to give 3–6 months’ written notice to exercise an option, diarise it from day one. You can also negotiate changes as part of exercising the option - often with the help of a lease review so any amendments are captured correctly.

Assignments And Subleasing

If you need to exit early, two common pathways are:

• Assignment: You transfer your lease to a new tenant with the landlord’s consent, usually documented in a Deed of Assignment of Lease.
• Sublease: You lease part or all of the premises to someone else for a period, while you remain responsible to the landlord. Use a proper commercial sublease agreement to manage risk.

Most leases require landlord consent for an assignment or sublease, and retail leases often include specific criteria and timelines for giving or refusing consent.

Holding Over (After A Fixed Term)

Many commercial leases include a “holding over” clause that converts the tenancy to month-to-month on the same terms once the fixed term ends, until one party ends it with the required notice. Confirm the notice period, permitted reasons to terminate during holding over, and how rent will be reviewed in that phase.

Documents And Safeguards To Have In Place

Whether you choose a fixed-term or periodic arrangement, well-drafted documents reduce disputes and protect your position. Consider the following:

• Commercial Lease Agreement: The core contract that sets permitted use, term, options, rent reviews, outgoings, fit-out, repairs, make-good, insurance, assignment rights and dispute processes. A pre-signing review by a commercial lease lawyer pays for itself if it avoids a single costly clause.
• Retail Lease Documents: If your premises is “retail,” you’ll have disclosure obligations and additional protections under retail leasing laws (for example, the Retail Leases Act (NSW)). Make sure the disclosure statement and lease align.
• Deed Of Assignment Of Lease: If you’re transferring your lease, formalise the transfer with a Deed of Assignment of Lease and align guarantees, bonds and make-good responsibilities.
• Commercial Sublease Agreement: If you’re subletting, a tailored sublease agreement will manage payment, use, indemnities, insurance and end-of-term obligations.
• Lease Variation Or Extension: If you’ve negotiated changes mid-term or extended the lease, document them in a short-form deed so there’s no ambiguity later.
• Notices And Renewals: Keep templates and clear diary reminders for option notices, market review triggers, and end-of-term notices. For NSW and QLD, see our summaries of renewal notice periods and timelines.

Most states expect leases to be in writing for commercial and retail arrangements, and there are prescribed forms and disclosures in the retail context. Even where an oral or implied agreement might be recognised, a written lease is the safest way to record what you’ve actually agreed.

Common Pitfalls (And How To Avoid Them)

• Assuming the same rules apply everywhere: Notice periods, “no grounds” terminations and retail lease disclosure rules vary by state and territory. Confirm what applies to your premises before you act.
• Unclear rent review mechanics: If the lease doesn’t clearly explain how and when rent increases, disputes follow. Lock down the method, timing and any caps.
• Missing option deadlines: If you don’t exercise your option correctly and on time, you may lose it. Use reminders and respond in the exact form required.
• Ignoring make-good: End-of-term make-good can be one of the biggest costs. Photograph the condition at the start and negotiate a fair, specific make-good clause.
• Overlooking assignment/sublease consent conditions: Most leases restrict transfer. Make sure the criteria for consent are realistic and time-bound, and document any landlord approvals.
• Serving notices incorrectly: The method and timing of notices matter. In NSW, for example, check the steps for a valid notice to vacate before you send anything.
• Signing without review: A short, fixed-fee lease review can flag issues with personal guarantees, outgoings, rent reviews and make-good - before they become expensive.

Key Takeaways

• A fixed-term lease gives certainty around time and rent, while a periodic lease offers flexibility - the right choice depends on your risk tolerance and plans for the premises.
• Ending rights, notice periods and rent reviews are determined by both your lease and state or territory legislation. Some jurisdictions restrict “no grounds” endings for periodic tenancies.
• At the end of a fixed term, you can renew, vacate, or “hold over” month-to-month (if the lease allows). Diarise option and notice deadlines from day one.
• Document assignments and subleases properly to manage liability and obtain landlord consent, with a Deed of Assignment or a commercial sublease agreement as needed.
• Retail leasing comes with extra disclosure and protection rules. Make sure your rent review, outgoings and fit-out obligations align with those requirements.
• Get your lease in writing, review it carefully, and seek targeted legal advice on anything unclear - a small investment now can prevent costly disputes later.
