If you’re running a small business, your premises can be one of your biggest overheads. So if you have spare space, a quiet period, or you’re scaling down (or up), subletting part (or all) of your premises can look like a smart move.
But before you download a sublease agreement template Australia from a search result and sign on the dotted line, it’s worth slowing down. Subletting is one of those commercial arrangements where the “simple” option can become expensive later - especially if your head lease doesn’t allow it, your landlord isn’t on board, or the sublease terms don’t match your lease obligations.
Below, we’ll walk you through how subleases work in Australia, what to check before you sublet, what a sublease agreement should include, and when you might need a different document altogether.
What Is A Sublease (And When Does It Make Sense For Small Businesses)?
A sublease is when you (the tenant under an existing commercial lease) lease out some or all of your leased premises to another party (the subtenant) for a period of time.
In practice, this often happens when:
- you have unused office/retail space and want to reduce rent pressure;
- your business is seasonal and you want someone else to use the space during quieter months;
- you’re trialling a new location but don’t want to permanently exit the lease;
- you’re sharing premises with a complementary business (for example, a salon subletting a room to a massage therapist); or
- you’re relocating, but your lease still has time to run.
A key point to understand: in most sublease arrangements, you remain responsible to the landlord under the original lease (often called the “head lease”). That means if your subtenant stops paying rent or damages the premises, the landlord may still look to you.
Because of that ongoing responsibility, a sublease agreement needs to do more than “cover rent and dates”. It needs to manage risk in a way that aligns with your head lease.
Can You Sublet? Start With Your Head Lease (And The Landlord’s Consent)
Before you start negotiating with a potential subtenant or using a sublease agreement template in Australia, your first step is to check whether you’re legally allowed to sublet under your head lease.
Many commercial leases either:
- prohibit subletting entirely; or
- allow subletting only with the landlord’s written consent (and often on conditions).
It’s also common for landlords to require certain things before they consent, such as:
- details about the proposed subtenant and their business;
- financial information (to assess risk);
- the proposed sublease document for review;
- an obligation that the sublease terms are consistent with the head lease; and/or
- payment of the landlord’s legal costs (this depends on the lease and negotiation).
If you sublet without the required consent, you could be in breach of your lease - and depending on your lease terms and the type of premises (for example, some retail leases are regulated by state and territory legislation), that breach may give the landlord enforceable rights, which can include issuing breach notices and, in some cases, termination or other remedies.
If you’re unsure what your lease allows (or what you can negotiate), it’s often worth getting advice early, especially before you commit to a subtenant. This is also where a Commercial Lease Review can help you understand your subletting rights and restrictions before you take action.
Sublease Vs Assignment: Are You Actually “Subletting”?
Small businesses often use “sublease” to mean “someone else takes over my premises”. But legally, there are two common pathways:
- Sublease: you create a new lease between you and the subtenant, while you remain the tenant under the head lease.
- Assignment: you transfer your lease interest to someone else (the assignee), usually with the landlord’s consent, and you may or may not remain liable depending on the terms negotiated.
If your real goal is to exit the premises completely, you may need a Deed of Assignment of Lease rather than a sublease.
This distinction matters because using the wrong “template” can leave you exposed - for example, you might think you’re off the hook, but your documents say otherwise.
Sublease Vs Licence: Is It Really A Lease Of Space?
Another common scenario is when you’re not giving someone exclusive possession of premises, but rather letting them use space on flexible terms - for example, a desk in your office, a chair in your salon, or access to a shared studio.
In that case, you might be looking at a licence arrangement instead of a sublease. Depending on your setup, a Property Licence Agreement may be the better fit.
Why does it matter? Because “lease-like” rights can sometimes arise even if you call it a licence - and the risk profile (and obligations to the landlord) can be very different.
What Should A Sublease Agreement Template In Australia Include?
A good sublease agreement template Australia should reflect your real-world arrangement, while also protecting you (as head tenant) and staying consistent with the head lease.
While every sublease is different, here are the clauses we typically expect to see addressed clearly.
1. The Relationship To The Head Lease
This is the backbone of a compliant sublease.
Your sublease should clearly deal with:
- the fact that the sublease is subject to the head lease;
- that the subtenant must comply with relevant head lease obligations (as far as they apply to the sublet area); and
- what happens if the head lease ends early (for example, expiry, termination, or surrender).
If your sublease ignores head lease requirements, you can end up in the middle of a three-way dispute where you’re liable to the landlord and also dealing with a subtenant who claims their rights were different.
2. Premises Description (Exactly What Is Being Sublet?)
Be precise about what space is being sublet. “The back room” sounds simple, but ambiguity creates conflict.
Consider including:
- a plan of the premises;
- the size (if known);
- exclusive areas vs shared/common areas; and
- storage rights, signage rights, and access arrangements.
This is especially important where you’re still operating in the same premises, because you’ll want clear rules about shared facilities, security, noise, and customer access.
3. Term, Option Periods, And Alignment With Your Lease End Date
Your sublease term generally can’t go beyond your own lease term. Even if it technically “can”, it creates a practical problem: you can’t grant rights you don’t have.
A well-drafted sublease should:
- state the start date and end date;
- deal with any “option” to renew (and make it conditional on your head lease continuing); and
- include handover/vacate obligations and make-good responsibilities.
Tip: If your lease ends in 10 months, a 2-year sublease template from the internet is not going to be appropriate without careful changes.
4. Rent, Outgoings, GST, And Payment Mechanics
Subleasing often starts with one question: “How much will they pay?”
Your sublease should clearly set out:
- base rent (and whether it’s weekly/monthly);
- any rent increases (fixed, CPI, market review, etc.);
- outgoings (for example, electricity, water, cleaning, building fees);
- bond or security deposit;
- GST treatment; and
- late payment consequences.
One of the biggest traps for head tenants is agreeing to “all-inclusive” rent, then realising the outgoings under the head lease are higher than expected - leaving you to cover the gap. (Note: Sprintlaw can help with the legal drafting and lease alignment, but we don’t provide tax or accounting advice - for GST and tax treatment, it’s best to check with your accountant.)
5. Permitted Use (And Keeping The Landlord Happy)
Your head lease will usually restrict “use” (what kind of business activities can be conducted). Your sublease should match that, and also protect you if the subtenant operates outside the permitted use.
Consider:
- defining permitted use narrowly (so you’re not surprised later);
- requiring compliance with all laws and building rules; and
- restricting nuisance, noise, odours, hazardous materials, and high-foot-traffic uses if relevant.
This is particularly important in shopping centres and mixed-use buildings, where landlords are quick to act if a tenant causes disruption.
6. Repairs, Maintenance, Damage, And “Make Good”
Repairs and make-good clauses are where subleases often go wrong - because people rely on generic templates that don’t match the head lease.
Make sure your sublease addresses:
- who is responsible for day-to-day repairs and maintenance;
- who pays for damage caused by the subtenant (and their staff/customers);
- alterations and fit-out approvals; and
- what condition the space must be returned in at the end.
As head tenant, you want the subtenant’s end-of-term obligations to help you meet your end-of-term obligations to the landlord.
7. Insurance And Risk Allocation
Insurance is often required under the head lease, and you may also want the subtenant to hold their own cover (depending on the business type).
Common provisions include:
- minimum insurance types and coverage levels;
- evidence of insurance on request;
- indemnities for loss caused by the subtenant; and
- what happens if there’s damage or a major incident.
8. Subtenant Defaults And Your Right To Step In
If the subtenant doesn’t pay rent, breaches the agreement, or refuses to leave at the end, you need clear enforcement rights.
Your sublease should cover:
- what counts as a default;
- notice periods to remedy breaches;
- termination rights;
- your right to recover costs; and
- what happens to the bond/security.
Generic templates often don’t reflect how quickly you may need to act to protect your position under the head lease.
Common Subletting Risks (And How To Avoid Them Before You Sign)
Subletting can be a great commercial decision - but it’s also a common source of disputes. Here are some of the biggest risk areas we see for small businesses.
Your Sublease Conflicts With Your Lease
This is the number one issue.
For example, your head lease might require landlord consent for signage, fit-outs, opening hours, or certain operational practices. If your sublease doesn’t match those restrictions, your subtenant may push back when you try to enforce them - and you could still be liable to the landlord.
You Assume Consent Will Be Easy (But It Isn’t)
Even where the lease allows subletting with consent, landlords can be cautious.
Delays are common, and landlords may request changes to your sublease terms. Build that time into your plan and avoid promising the subtenant a start date until consent is handled.
You’re Actually Better Off With A Different Arrangement
Sometimes a sublease isn’t the right tool. If you just want to let someone use your space a few days a week, a licence arrangement may be more appropriate. If you want to exit the lease entirely, assignment may be the better path.
Using the wrong document can create legal uncertainty (and extra expense) when something goes wrong.
You Don’t Clarify Who Deals With The Landlord (And Building Management)
Even though the subtenant is operating from the premises, the landlord’s contractual relationship is with you.
It helps to clarify in the sublease:
- who communicates with the landlord/building manager day-to-day;
- whether the subtenant can request repairs directly; and
- how complaints, breaches, or emergencies are handled.
This avoids confusion and ensures you stay in control of the relationship that matters most - the one with your landlord.
A Practical Checklist: What To Do Before Using A Sublease Agreement Template In Australia
If you want to move quickly while still protecting your business, here’s a practical step-by-step approach.
1. Review Your Head Lease
Confirm whether subletting is allowed and what conditions apply (consent, form of document, permitted use, insurance, etc.).
2. Speak With Your Landlord Early
Even if the lease says consent “won’t be unreasonably withheld,” you’ll usually get a smoother process by discussing the plan early and providing the right information upfront.
3. Decide Whether You Need A Sublease, Assignment, Or Licence
Get clear on your goal:
- If you’re keeping the lease and just renting out space, a sublease is likely.
- If you’re leaving and want someone else to take over, you may need assignment.
- If you’re sharing space without exclusive possession, a licence may suit.
4. Clarify The Commercial Terms In Writing
Before drafting, agree (at least in principle) on the key commercial points: rent, outgoings, term, bond, permitted use, and make-good obligations.
5. Prepare A Tailored Sublease Agreement
A sublease agreement template can be a starting point, but it needs to be tailored to:
- your head lease restrictions;
- the physical layout of the premises (especially shared spaces); and
- your risk profile as head tenant.
If you need the document drafted end-to-end, a Commercial Sublease Agreement prepared for your specific situation can help you avoid mismatched terms and hidden gaps.
6. Don’t Forget Your Other Legal Foundations
Subletting is only one part of your legal setup. Depending on your arrangement, you may also need to think about:
- confidentiality if the subtenant will have access to sensitive information (for example, client lists or supplier pricing); and
- staff and workplace rules if you’re sharing premises with different teams.
If you’re growing and bringing on staff during this process, having the right Employment Contract in place can help set expectations clearly from day one.
Key Takeaways
- A sublease can help small businesses reduce costs or share space, but you usually remain responsible to the landlord under the head lease.
- Before using a sublease agreement template Australia, check your head lease for subletting restrictions and whether landlord consent is required.
- Make sure you’re using the right type of document - sometimes an assignment or a licence agreement is more appropriate than a sublease.
- A good sublease agreement should clearly cover: the relationship to the head lease, the exact area being sublet, rent and outgoings, permitted use, repairs/make-good, insurance, and default/termination rights.
- The biggest subletting risks usually come from mismatches between the sublease and head lease, unclear responsibilities, and generic templates that don’t reflect your actual setup.
