Ending a Contract of Service, a Step-by-Step Guide for Australian Businesses

Every business eventually ends a contract it would rather keep running: a supplier you no longer need, a contractor whose engagement has run its course, an employee who is not working out. How you close the relationship matters almost as much as how you began it, because a termination that is not legally sound can turn into an unfair dismissal claim, a breach of contract suit or a dispute over unpaid invoices.

Working through the steps in the right order gets you to a defensible result: a letter that identifies the contract, states the lawful ground, sets the effective date and is served exactly as the agreement requires. One misunderstanding to clear up at the start. In Australian law the letter does not, by itself, end the contract. It is only effective if you hold a ground to terminate and you follow the notice mechanics the contract, and for employees the Fair Work Act 2009 (Cth), impose. If the other party later challenges the termination, the paperwork is only as strong as the basis behind it.

What to confirm before you draft anything

Work through these prerequisites first. Each one shapes what your letter can and cannot say:

• Contract type: Whether you hold a contract of service, meaning an employment relationship, or a contract for services, meaning an independent contractor arrangement. Different law governs each, and getting this wrong is the most expensive mistake in this area.
• The written agreement: Your termination, notice, breach and notices clauses. If there is no written contract, the terms may come from an award, an enterprise agreement or the common law, which is harder to rely on.
• A lawful ground: Termination for convenience, breach, expiry of a fixed term, mutual agreement or frustration. You need one before you draft anything.
• The notice figure: The contractual notice period and, for employees, the National Employment Standards minimums, which a contract cannot undercut.
• Evidence of breach: If you are terminating for breach, collate the emails, performance records or unpaid invoices, and confirm you issued any required rectification or show-cause notice first.
• Fair Work exposure: For employees, check length of service against the unfair dismissal thresholds and the Small Business Fair Dismissal Code before you act.

The steps to ending the contract

Classify the relationship first

Australian law draws a sharp line between a contract of service and a contract for services. A contract of service is an employment relationship; a contract for services is an independent contractor arrangement. The High Court has distinguished the two for decades, from Stevens v Brodribb Sawmilling Co Pty Ltd (1986) 160 CLR 16 through Hollis v Vabu Pty Ltd (2001) 207 CLR 21, where bicycle couriers were held to be employees despite being labelled independent contractors. The label the parties choose is not decisive.

The High Court's 2022 decisions in CFMMEU v Personnel Contracting Pty Ltd [2022] HCA 1 and ZG Operations Australia Pty Ltd v Jamsek [2022] HCA 2 re-emphasised the written contract, and Parliament responded. Section 15AA of the Fair Work Act 2009 (Cth) now directs that whether an individual is an employee is determined by the real substance, practical reality and true nature of the relationship, considering the totality of the relationship including how the contract is performed in practice. Control, who supplies equipment, who bears the risk of loss and whether the worker can delegate are the kind of factors a court weighs.

Classification drives everything that follows. Employees are entitled to minimum notice of termination, can be protected against unfair dismissal and cannot contract out of the National Employment Standards. Independent contractors are governed by the contract itself, but since 26 August 2024 they can apply to the Fair Work Commission to set aside or vary unfair terms in a services contract, including termination terms, where their annual earnings are below the contractor high income threshold of $190,100 for the financial year starting 1 July 2026.

Confirm the ground for termination

Most grounds come from the contract itself. Termination for convenience lets either party end the agreement on notice without proving breach, provided you follow the notice period and the method of service exactly. Termination for breach requires a breach serious enough to go to the root of the contract, or a breach the contract identifies as terminable, and many contracts impose a cure period before you may act. Expiry of a fixed term ends the contract automatically, though employment fixed terms are now capped: a fixed-term employment contract cannot run for more than two years, cannot be renewed more than once or extended beyond two years in total, and consecutive fixed-term contracts for the same or substantially similar work are limited the same way under s 333E of the Fair Work Act. If you enter a prohibited fixed-term contract, the fixed-term element has no effect, which can expose you to notice and unfair dismissal obligations under s 333G.

Mutual agreement is the cleanest ground: both sides agree to end early, often recorded in a deed of termination or a deed of release and settlement. Frustration is rare and only applies where events outside both parties' control make performance impossible; rely on it only with legal advice.

Calculate notice, final pay and other amounts

For employees, s 117 of the Fair Work Act requires written notice of the day of termination, and a minimum notice period that runs from the day after notice is given. The National Employment Standards minimums are one week for up to one year of service, two weeks for one to three years, three weeks for three to five years and four weeks beyond five years, with an extra week for employees over 45 with at least two years of service. Payment in lieu of notice is permitted: employment ends immediately and the employee is paid what they would have earned across the notice period, including loadings, bonuses and allowances. A longer period may be required by an award, an enterprise agreement or the contract itself. Casual employees are not entitled to notice, and neither are employees dismissed for serious misconduct such as theft or fraud, though outstanding entitlements such as accrued annual leave must still be paid. If the dismissal is a genuine redundancy, check whether redundancy pay applies on top of notice. And be aware that dismissing an employee because they exercised a workplace right, such as asking about their pay, can itself attract a general protections claim.

For contractors, notice and final payments come from the contract: the notice period, the treatment of work in progress, outstanding invoices and any early-termination fees. Work the numbers out before you draft the letter so the amounts in it are correct.

Draft the termination letter

A well-drafted letter is factual and complete. It should identify the parties and the contract, state the clause and ground relied on, give the effective date, confirm the notice period or payment in lieu, set out final amounts and invoicing, require the return of property and data, and remind the other party of obligations that survive termination such as confidentiality, intellectual property and restraints. State the method of service you are using so there is no dispute later about whether notice was validly given. A template that covers those elements:

Subject: Notice of termination of [Contract name] dated [date]

Dear [Name],

We refer to the [contract name] between [your entity] (ABN [ABN]) and [other party] (ABN [ABN]) dated [date] (the Contract).

Pursuant to clause [X] of the Contract, we give notice that the Contract is terminated with effect from [date]. The period of notice required under clause [Y] has been given. [Alternatively: Payment in lieu of notice of [amount] will be made with our final payment.]

[If terminating for breach: We refer to our notice dated [date] identifying the following material breach or breaches: [describe]. The breach was not remedied within the cure period in clause [Z]. We therefore terminate under clause [W].]

Final accounts and handover:

• [Amounts owing, outstanding invoices, refunds or settlement sums, and when payment will be made]
• [Return of all property, materials, access credentials and confidential information by [date]]
• [Transition assistance, for example [number] business days of cooperation to hand over work]

Continuing obligations: your obligations regarding confidentiality, intellectual property, privacy and any post-termination restrictions continue in accordance with clauses [V] of the Contract.

Method of service: this notice is given in accordance with clause [U] of the Contract.

Please contact [name] at [email] or [phone] with any questions.

Yours sincerely, [Name], [Title]

Keep the tone professional. Avoid emotive language and admissions beyond what is needed to ground the termination; a letter written in anger can be used against you in a later dispute.

Serve the letter exactly as the contract requires

Most contracts have a notices clause specifying the address, the recipient and the method of delivery, such as registered post or email to a nominated address. Follow it to the letter, because notice served the wrong way may be no notice at all. For employees, written notice can be delivered personally, left at the employee's last known address, sent by pre-paid post or sent electronically with the employee's agreement. Keep proof of delivery and note the effective date in your records.

Close out access, property and data

Termination is not complete when the letter is sent. Revoke system access, collect equipment and access cards, secure confidential information and arrange the return or destruction of data in writing. If the contract assigns intellectual property, confirm you have received all deliverables and that ownership has transferred. For client-facing work, agree a transition and handover plan so customers are not caught mid-project.

Finalise with a deed and update your records

Where the relationship is contentious, or you want finality, pair the letter with a deed of termination or a deed of release and settlement. Deeds can include mutual releases, settlement of disputed amounts, confidentiality and non-disparagement, and they bind without the need for fresh consideration. Execution is stricter than for ordinary contracts: a deed must be signed, sealed and delivered, and a company must execute it in the way the Corporations Act 2001 (Cth) requires. A lawyer should settle the deed's terms. Finally, update your precedents: tightening the termination, notice, cure and transition clauses in your standard agreements makes the next ending cheaper and safer.

Where businesses typically get held up

Terminations usually come unstuck in one of a handful of recurring places:

• Serving notice the wrong way: Sending the letter to the wrong address, the wrong person or by the wrong method can invalidate the notice even when the grounds are sound.
• Misclassifying the worker: Treating an employee as a contractor, or vice versa, means applying the wrong termination rules. The classification tests above, not the label in the contract, decide which side you are on.
• Terminating for breach too early: If the contract requires a rectification or show-cause step first, terminating early can itself be a repudiation that exposes you to damages.
• Letting fixed-term contracts drift past the limits: A fixed-term employee kept on beyond two years, or renewed more than once, can lose the fixed-term character of the arrangement entirely.
• Forgetting what survives: Post-termination confidentiality, IP and restraint obligations only bind if they are drafted into the contract and reminded in the letter.

When a lawyer should be involved

Most terminations are routine, but several situations justify advice before you send anything. If the grounds are arguable, the relationship is hostile, the amounts are large or there is any doubt about classification, a legal practitioner can review the contract and confirm whether the ground is sound, check your Fair Work obligations including unfair dismissal exposure and redundancy pay, draft or settle the letter and any deed, assess whether a contractor could challenge a term as unfair in the Fair Work Commission, and handle the dispute if termination is resisted. A short review before you act is far cheaper than defending a claim afterwards.

What makes a termination stick

The factor that most often decides whether an ending holds up is the match between your ground, the clause you rely on, the notice you give and the way you serve it. A letter that gets any one of those wrong can fail even when the business reasons for ending the contract were entirely reasonable.

End the relationship the way the contract, and for employees the Fair Work Act, allow: classify the relationship correctly, confirm the ground, calculate notice and final amounts, draft a factual letter, serve it by the required method, close out access and data, and use a deed where finality matters. Done in that order, the ending is professional, documented and defensible, and a lawyer's review can confirm each step before it is too late to fix.
