Break Lease SA — Guide for Self-Managing Landlords

If your tenant wants to leave a fixed-term lease early in South Australia, the rules are different from every other state. SA does not use a flat break fee schedule like NSW or Victoria. Instead, the Residential Tenancies Act 1995 gives tenants a statutory cap on their rent liability under section 75A, while requiring the landlord to mitigate loss by reletting as quickly as possible. The tenant’s total exposure is a combination of lost rent (subject to the cap), a pro-rated reletting fee, and pro-rated advertising costs — calculated using a formula that SACAT applies in disputes.

On top of that, the 2024–2025 reforms introduced several new grounds on which a tenant can terminate a fixed-term lease with as little as seven days’ notice and no break lease costs at all — including domestic abuse, premises that don’t meet minimum housing standards, and successive landlord breaches.

In this guide, we’ll cover what a landlord can and cannot claim when a tenant breaks a lease early, how the cost formulas work, what the 2024–2025 reforms changed, the specific termination grounds that override break lease costs entirely, and the most common mistakes landlords make.

If a tenant wants to leave early, start with the SA lease agreement guide and the broader SA residential tenancies act guide. If money or damage may be disputed at the end, our SA rental bond guide guide is the natural companion page.

How Break Lease Costs Work in SA

SA’s approach to early lease termination is fundamentally different from states like NSW and Victoria, which use a fixed break fee based on how far into the lease the tenant is. In SA, there is no prescribed break fee. Instead, the tenant is liable for the landlord’s actual loss — but that loss is subject to two important constraints.

First, the landlord has a duty to mitigate under section 78 of the Residential Tenancies Act 1995. This means you must take reasonable steps to find a replacement tenant as quickly as possible. If you do not attempt to relet the premises, the tenant may not be liable for anything. The duty to mitigate is not optional — it is a legal obligation, and SACAT will scrutinise whether you made genuine efforts to relet.

Second, section 75A caps the amount of rent a tenant can be liable for after they terminate a fixed-term tenancy early. The cap works as follows.

If the term remaining on the agreement after the tenant gives up possession is less than 24 months, the tenant’s maximum liability for rent is one month’s rent. If 24 months or more remain, the maximum is one month’s rent for each whole 12-month period remaining — but the tenant cannot be liable for more than six months’ rent in total under section 75A.

Importantly, section 75A only caps the tenant’s liability for rent. It does not affect the landlord’s entitlement to compensation for other costs associated with the early termination — specifically, advertising costs and the reletting fee. These are calculated separately.

What You Can Claim from the Tenant

When a tenant breaks a fixed-term lease early in SA, you are entitled to recover three categories of cost: lost rent, the reletting fee, and advertising costs. Each is subject to its own rules.

Lost Rent

The tenant is liable for rent from the date they vacate until the earlier of the date a new tenant moves in or the end of the fixed term. This liability is subject to the section 75A cap described above. If you relet the property within the capped period, the tenant’s rent liability ends on the date the new tenancy begins — even if this is less than the cap.

If the tenant does not negotiate with you and simply leaves (abandons the tenancy), they remain liable for rent to the date you relet the property or the end of the fixed term — whichever is sooner — subject to the section 75A cap. You are also entitled to claim pro-rated reletting and advertising costs. However, your duty to mitigate still applies: if you do not attempt to relet the premises, the tenant may not be liable for anything.

Reletting Fee

The reletting fee is capped at a maximum of two weeks’ rent plus GST. However, this maximum only applies if the tenant leaves very early in the lease. If the tenant has been there for at least a quarter of the total lease term, the reletting fee is pro-rated based on the proportion of the lease remaining.

Consumer and Business Services (CBS) publishes the formula that SACAT generally applies:

Reletting fee = (maximum reletting fee) × (weeks remaining from reletting to end of term) ÷ (percentage of weeks of total agreed term)

The “percentage of weeks” figure is 75% of the total weeks of the lease. For a 12-month (52-week) lease, the denominator is 39. For a 6-month (26-week) lease, it is 19.5.

For example, on a 12-month lease with rent of $500 per week, if the property is relet 12 weeks before the end of the fixed term, the reletting fee calculation is: ($1,000 + GST) × 12 ÷ 39. The GST component (10%) charged by agents can be recovered from the tenant.

If the tenant has not been in the property for at least a quarter of the total lease term, the full reletting fee (two weeks’ rent plus GST) applies without pro-rating.

Advertising Costs

Advertising costs are the actual costs you incur to advertise the property for reletting. Like the reletting fee, these are pro-rated using the same formula:

Advertising costs = (total advertising costs) × (weeks remaining from abandonment to end of term) ÷ (percentage of weeks of total agreed term)

For example, if total advertising costs are $200 and the tenant abandons the property 12 weeks before the end of a 52-week lease: $200 × 12 ÷ 39 = $61.54.

Note that reletting and advertising costs cannot be claimed if the property is not re-advertised or relet as soon as possible. If you delay advertising or are not genuinely seeking a replacement tenant, you undermine your entitlement to these costs.

The Section 75A Liability Cap in Practice

The section 75A cap is one of the most significant protections for tenants in SA and one of the most misunderstood provisions for landlords. Here is how it applies in common scenarios.

12-month lease, tenant leaves after 6 months (6 months remaining). Less than 24 months remain, so the maximum rent liability is one month’s rent. The tenant also owes pro-rated reletting and advertising costs. Even if it takes you three months to find a new tenant, the tenant’s rent liability is capped at one month.

24-month lease, tenant leaves after 6 months (18 months remaining). Less than 24 months remain, so the maximum rent liability is still one month’s rent.

36-month lease, tenant leaves after 6 months (30 months remaining). More than 24 months remain. There are two whole 12-month periods remaining, so the maximum rent liability is two months’ rent.

5-year lease, tenant leaves after 6 months (54 months remaining). More than 24 months remain. There are four whole 12-month periods remaining, so the maximum would be four months’ rent. The six-month absolute cap does not apply here because four months is below it.

The cap applies regardless of how long it actually takes you to relet the property. If you relet within two weeks, the tenant only owes two weeks’ rent — even though the cap would have allowed one month. The cap is a ceiling, not a guaranteed entitlement.

Section 75A(2) confirms that the rent cap does not affect your entitlement to compensation for other costs (reletting and advertising). These remain claimable on top of the capped rent amount.

When a Tenant Can Terminate Without Break Lease Costs

SA law provides several grounds on which a tenant can terminate a fixed-term lease early with no liability for break lease costs. As a self-managing landlord, you need to know these grounds because if the tenant terminates validly on one of them, you cannot claim lost rent, reletting fees, or advertising costs.

Domestic Abuse (Section 85D — Form 15)

A tenant can terminate the tenancy by giving notice using Form 15 if an intervention order is in force protecting the tenant or a domestic associate who normally resides at the premises, or if an authorised professional (a legal practitioner, registered health practitioner, social worker, or a person employed by a domestic violence or sexual abuse support service) provides a report confirming circumstances of domestic abuse.

The notice must be accompanied by either a copy of the intervention order or the prescribed professional report. There is no minimum notice period specified — the tenant nominates the handover date. As a landlord, you are required to deal with the evidence you receive confidentially. Criminal penalties of up to $50,000 apply for misuse or inappropriate disclosure of the evidentiary documents.

Premises Do Not Meet Minimum Housing Standards (Section 85B — Form 14)

A tenant can give seven days’ notice of termination if the premises do not comply with the prescribed minimum housing standards under the Housing Improvement Act 2016. From 1 July 2024, landlords must ensure premises meet minimum housing standards at or before the tenant enters occupation. If you fail to do so, the tenant has a right to terminate.

Premises Destroyed or Unsafe (Section 85B — Form 14)

If the premises are totally destroyed or destroyed to the extent that they are unsafe, the tenant can give seven days’ notice using Form 14.

Immediate Termination — Premises Uninhabitable (Section 86B — Form 18)

If the premises or a substantial portion have been destroyed or rendered uninhabitable, are no longer lawfully usable as residential premises, or have been acquired by compulsory process, the tenant can terminate immediately using Form 18.

Successive Breaches by the Landlord (Section 85AA — Form 12)

If the landlord has breached the same provision of the tenancy agreement on two previous occasions within the last 12 months, and then breaches it again, the tenant can give seven days’ notice using Form 12.

Aged Care, Crisis Accommodation, or Community Housing (Section 85C — Form 14)

A tenant can give seven days’ notice using Form 14 if they require prescribed care (aged, palliative, or special care), have been offered and accepted accommodation by the South Australian Housing Trust, a subsidiary of the South Australian Housing Trust, or a registered community housing provider, or require prescribed temporary crisis accommodation.

Undisclosed Sale of Premises (Section 85A — Form 13)

If, within two months of the start of the tenancy agreement, the landlord enters into a contract for sale of the premises and did not disclose this before the agreement was signed (as required under section 47A), the tenant can terminate using Form 13. The tenant must exercise this right within two months of receiving written notice of the sale.

Undue Hardship (Section 89 — SACAT Application)

A tenant can apply to SACAT to terminate the tenancy if continuation would result in undue hardship. This is not a notice-based termination — it requires a Tribunal application. SACAT may make an order compensating the landlord for loss and inconvenience resulting from the early termination, but the compensation amount is at the Tribunal’s discretion.

What Happens When a Tenant Gives a Termination Notice After You Serve One

If you serve a notice of termination on the tenant (for example, a Form 9 non-renewal notice at the end of a fixed term), the tenant does not have to wait until the date specified in your notice. Under section 83A(3) of the Act, the tenant can give up possession before the end of the fixed term and will not be liable to pay rent after either the day possession is given up (if they give at least seven days’ written notice) or the seventh day after notice is given (if they give less than seven days’ notice).

This is important for self-managing landlords who serve a Form 9 with 60 days’ notice. If your tenant responds with seven days’ notice to vacate, you will have the property back sooner than expected — but you lose the rent for the remaining notice period. The tenant is not “breaking the lease” in this situation and owes no break lease costs.

However, there is an exception. Under section 83A(4) and regulation 26, the early vacation right does not apply if the termination ground also constitutes a breach of the tenancy agreement. For example, if you terminate at the end of a fixed term because the tenant has repeatedly breached the agreement (a ground prescribed under regulation 25), the tenant cannot simply give seven days’ notice and stop paying rent. In that situation, the tenant remains liable for rent until they vacate on the date specified in your termination notice.

Assignment and Subletting as an Alternative

Before a tenant resorts to breaking the lease, they may seek to assign the lease to a new tenant or sublet the premises. Under section 74 of the Act, a tenant can assign or sublet the whole or part of the premises, but only with the landlord’s consent. The landlord’s consent must not be unreasonably withheld.

If you do unreasonably withhold consent, the tenant can apply to SACAT for a determination that consent is not required, and the assignment or subletting may proceed without your consent. You cannot charge a fee for giving consent to an assignment or subletting — this carries a maximum penalty of $20,000 and an expiation fee of $1,200. However, you can require the tenant to bear any reasonable expenses you incur because of the assignment or subletting.

An assignment transfers the entire remaining lease to a new tenant, ending the original tenant’s obligations. A sublet creates a secondary tenancy under the original lease — the original tenant remains liable to you. From a practical standpoint, an assignment is usually the cleaner outcome for both parties when a tenant needs to leave early.

Your Duty to Mitigate

Section 78 of the Act applies the common law rules about mitigation of loss to breaches of residential tenancy agreements. In the break lease context, this means you must take reasonable steps to relet the property as quickly as possible after the tenant vacates.

What counts as reasonable steps? Advertising the property promptly on major platforms, pricing the property at market rent (not above what the departing tenant was paying if market conditions have changed), making the property available for inspections, and considering reasonable applications without unnecessary delay.

If you do not attempt to relet the premises, the tenant may not be liable for anything — even if the fixed term has not expired. SACAT will examine whether your mitigation efforts were genuine. Listing the property at an unreasonably high rent, refusing to show the property, or waiting weeks before advertising will all count against you.

The tenant’s liability for rent runs only to the date of reletting or the end of the fixed term (whichever is sooner). If you relet the property quickly, the tenant’s rent liability is minimal — regardless of how much time remained on the lease.

Bond and Break Lease Costs

The rental bond cannot be used to cover break lease costs without the tenant’s agreement. If you and the tenant agree on the break lease costs, you can make a joint application to Consumer and Business Services to have the relevant portion of the bond paid to you. If you cannot agree, either party can apply to SACAT to determine the bond distribution.

You should not withhold the bond or refuse to process a bond claim simply because you believe break lease costs are owed. The bond is held by the Commissioner for Consumer Affairs in the Residential Tenancies Fund — it is not your money to hold. If you want to claim against the bond for break lease costs, you need to either reach agreement with the tenant or obtain a SACAT order.

Commissioner-Determined Compensation

Under section 84A, where a tenant has breached the tenancy agreement or engaged in drug-related conduct on the premises, the landlord is entitled to costs or expenses determined by the Commissioner for Consumer Affairs in connection with the termination. This is separate from the break lease cost formulas described above and applies in prescribed circumstances under regulation 27. If your tenant’s early departure involves a breach of the agreement, you may be entitled to Commissioner-determined compensation in addition to the standard break lease costs.

Retaliatory Termination Protections

Under section 90A, SACAT may declare a termination notice ineffective if it is satisfied the notice was retaliatory — that is, the landlord was wholly or partly motivated by an application to SACAT by the tenant, or action taken or proposed by the tenant to enforce their rights. This applies to landlord-initiated terminations, not tenant break leases, but it is relevant context: if a tenant breaks a lease shortly after you serve a notice that SACAT later finds was retaliatory, the Tribunal may take a dim view of any break lease claim.

Prohibition on Reletting After Landlord Termination

If you terminate a tenancy on a ground prescribed by the Regulations (demolition, renovation, landlord or family occupation, contract of sale, or sales agency agreement), you must not relet the premises for use primarily as a residence within six months of the date the notice was given, unless you apply to SACAT for permission. This restriction applies to landlord-initiated terminations under sections 81 and 83A — it does not apply when the tenant breaks the lease.

Accepting Rent After a Termination Notice

Section 117 of the Act provides that a landlord’s notice of termination is not waived by acceptance of rent. This means you can continue to accept rent from the tenant after serving a termination notice without losing the right to enforce the notice. This is relevant in break lease situations where the tenant has indicated they will leave but continues to pay rent in the interim — accepting those payments does not create a new tenancy or waive the termination.

If an early exit turns into a money or damage dispute, our SA rental bond guide guide explains the money side. If the tenancy ends through a formal notice instead, see our SA eviction notice guide guide.

Common Mistakes Landlords Make with Break Leases in SA

Treating the Section 75A Cap as a Guaranteed Payment

The cap under section 75A is a ceiling on the tenant’s rent liability — not a minimum. If you relet the property within one week, the tenant owes one week’s rent, not one month. The cap only applies if you cannot relet within the capped period. Many landlords assume they are automatically entitled to one month’s rent; this is incorrect.

Failing to Mitigate

The single most common mistake. If you do not advertise the property, do not show it to prospective tenants, or list it at an unreasonably high rent, SACAT will reduce or eliminate the tenant’s liability. The duty to mitigate is not discretionary — it is a legal obligation under section 78.

Claiming the Full Reletting Fee When the Tenant Left Late in the Lease

The reletting fee is pro-rated based on the proportion of the lease remaining. If the tenant leaves with only a few weeks remaining, the pro-rated reletting fee will be a fraction of the two-week maximum. Claiming the full two weeks when the tenant was there for most of the lease will not hold up at SACAT.

Withholding the Entire Bond

The bond is not a break lease penalty. You cannot withhold the entire bond and treat it as compensation for the early termination. You can only claim against the bond for the specific costs you are entitled to — lost rent (subject to the cap), pro-rated reletting fee, and pro-rated advertising costs. Any remainder must be returned to the tenant.

Ignoring Valid Tenant Termination Grounds

If the tenant terminates on a valid statutory ground (domestic abuse, housing standards, successive breaches, destruction, aged care, or crisis accommodation), they owe no break lease costs. Pursuing a break lease claim against a tenant who terminated validly will fail at SACAT and may result in costs against you.

Not Keeping Records of Mitigation Efforts

If the matter goes to SACAT, you will need to demonstrate what steps you took to relet the property. Keep records of when the property was listed, where it was advertised, how many enquiries and inspections you received, and why any applications were declined. Without this evidence, the tenant can argue you failed to mitigate.

Charging a Fee for Consent to Assignment

If the tenant asks to assign the lease to a replacement tenant and you charge a fee for giving consent, you are committing an offence carrying a maximum penalty of $20,000. You can recover reasonable expenses incurred because of the assignment, but you cannot charge a fee for the consent itself.

Frequently Asked Questions About Breaking a Lease in SA

Is there a flat break fee in SA like in NSW? No. SA does not have a fixed break fee schedule. Instead, the tenant’s liability is based on actual loss (lost rent, reletting fee, and advertising costs), subject to the section 75A rent cap. The costs are calculated using formulas published by Consumer and Business Services.

What is the maximum rent a tenant can owe for breaking a lease early? Under section 75A of the Residential Tenancies Act 1995, if less than 24 months remain on the lease, the maximum is one month’s rent. If 24 months or more remain, it is one month’s rent for each whole 12-month period remaining, capped at six months’ rent in total. This cap applies to rent only — reletting and advertising costs are separate.

Do I have to try to find a new tenant? Yes. Under section 78, you have a legal duty to mitigate your loss by seeking a replacement tenant as quickly as possible. If you do not attempt to relet the premises, the tenant may not owe you anything.

Can I claim the full reletting fee? Only if the tenant leaves very early in the lease (within the first quarter of the total term). After that, the reletting fee is pro-rated using the CBS formula based on how much of the lease remains. The maximum reletting fee is two weeks’ rent plus GST.

Can I use the bond to cover break lease costs? Only with the tenant’s agreement or a SACAT order. You cannot unilaterally withhold the bond as compensation for break lease costs. If you and the tenant agree on the costs, you can make a joint application to Consumer and Business Services.

What if the tenant just leaves without giving notice? This is treated as abandonment. The tenant remains liable for rent to the date you relet the property or the end of the fixed term (whichever is sooner), subject to the section 75A rent cap, plus pro-rated reletting and advertising costs. Your duty to mitigate still applies — you must attempt to relet the property promptly.

Can a tenant break a lease because of domestic abuse? Yes. Under section 85D, a tenant can terminate by serving a Form 15 notice with evidence of an intervention order or a prescribed report from an authorised professional. No break lease costs apply. Criminal penalties of up to $50,000 apply if you misuse or disclose the supporting evidence.

What if the tenant wants to assign the lease to someone else? The tenant can propose an assignment under section 74, and you must not unreasonably withhold consent. If you do, the tenant can apply to SACAT for a determination that consent is not required. You cannot charge a fee for giving consent, though you can recover reasonable expenses.

Can a tenant break a lease because the property doesn’t meet housing standards? Yes. Under section 85B, a tenant can give seven days’ notice using Form 14 if the premises do not comply with the minimum housing standards under the Housing Improvement Act 2016. No break lease costs apply.

What happens if I serve a termination notice and the tenant leaves early? Under section 83A(3), once you serve a termination notice at the end of a fixed term, the tenant can give up possession early. If they give at least seven days’ written notice, they are not liable for rent after the day they vacate. This is not a break lease — it is the tenant exercising a statutory right. However, this right does not apply if the termination ground also constitutes a breach of the agreement (regulation 26).

Summary

Breaking a lease in SA is not governed by a simple break fee table. The framework is built on actual loss, a statutory rent cap under section 75A, and a mandatory duty to mitigate. As a self-managing landlord, your ability to recover costs depends entirely on how quickly you relet the property and how well you document your efforts.

The 2024–2025 reforms added significant new termination rights for tenants — particularly around domestic abuse, minimum housing standards, and successive landlord breaches. If a tenant terminates on any of these grounds, break lease costs do not apply. Understanding which terminations trigger liability and which do not is essential for managing your property lawfully.
