Dismissing a casual employee in Australia

You have decided to end a casual employee's engagement. Perhaps the work has dried up, a conduct issue has escalated, or the arrangement simply isn't working. The decision feels straightforward — casuals are flexible, and that's the point. But "flexible" does not mean "consequence-free." Australian law imposes real obligations on how a casual employment relationship ends, and the consequences of getting the process wrong can include unfair dismissal applications, general protections claims, and discrimination complaints.

What you end up with at the other side of this process is a clean separation: the casual's engagement concluded, final wages paid correctly and on time, a paper trail that supports your decision if challenged, and no outstanding exposure from a procedural misstep. One thing this process does not produce automatically is immunity from claims — that comes from following a fair and lawful pathway every time.

Before you start: prerequisites

Tick these off before you take any step toward terminating a casual engagement.

• Confirm the casual's status. Under s 15A of the Fair Work Act 2009 (Cth), a casual employee is someone whose employment relationship has no firm advance commitment to continuing and indefinite work, assessed on the real substance and practical reality of the arrangement — not just the label in the contract. If the engagement has in practice become regular and systematic, the legal picture is more nuanced.
• Identify the applicable modern award or enterprise agreement. Many awards include specific procedural requirements — consultation obligations, warnings, or minimum notice — that apply even to casuals. These override the NES minimum (which for casuals is zero notice) where they are more favourable to the employee.
• Have the contract, rosters, and any written warnings to hand. You will need these to check what the contract says about termination, to assess the pattern of engagement, and to support any decision you make.
• Know whether your business is a small business employer. Businesses with fewer than 15 employees must follow the Small Business Fair Dismissal Code where it applies. The headcount includes casuals employed on a regular and systematic basis.
• Confirm the reason is lawful. The reason must relate to the employee's capacity, conduct, or genuine operational need — not to a protected attribute (such as race, sex, age, disability, or pregnancy) or the exercise of a workplace right (such as making a complaint or raising a safety concern).
• Check whether the casual may be eligible for unfair dismissal. Under s 382 of the Fair Work Act 2009 (Cth), read with s 384, a casual who has worked on a regular and systematic basis with a reasonable expectation of continuing employment, and who has completed the minimum employment period — six months for most employers, 12 months for a small business employer — is protected from unfair dismissal.

Step 1: Check the contract and any applicable award or agreement

Before any conversation with the employee, pull out the relevant documents. Review the casual employment contract for any termination clause, notice provision, or procedural requirement the business has committed to. Then check whether a modern award or enterprise agreement applies to the role.

What the award or agreement may impose:

• A specified process before dismissal for underperformance (for example, warnings, a performance improvement period, or a show-cause opportunity)
• Consultation requirements before ending engagement due to operational change
• A minimum notice period or payment in lieu that applies to casuals covered by that instrument — even though the NES does not require notice for casuals

If no award applies and the contract is silent on process, you still need to follow a procedurally fair pathway to protect against unfair dismissal and adverse action claims.

Where people get held up: Assuming that because there is no NES notice requirement for casuals, no process is needed at all. That assumption is wrong. Unfair dismissal law looks at whether the dismissal was harsh, unjust, or unreasonable — which includes how the decision was made, not just whether a reason existed.

Step 2: Investigate the issue

For conduct or performance matters, gather the facts before drawing any conclusion. Speak to witnesses, review relevant records, and put together a clear picture of what happened. Where allegations are serious, consider whether a short period of limited rostering or paid suspension is appropriate while you investigate — this must be consistent with the contract and any applicable award.

What a proper investigation produces:

• A clear account of the facts, including dates, witnesses, and relevant documents
• An assessment of the seriousness of the issue
• A record that supports the reason for dismissal if it is later challenged

Where people get held up: Moving too quickly from allegation to termination without gathering the facts. Even in cases of apparent serious misconduct, a failure to investigate properly can render a dismissal procedurally unfair — even if the underlying conduct was genuinely serious.

Step 3: Provide procedural fairness

Unless the conduct is so serious that immediate dismissal is clearly justified, the employee should be given an opportunity to respond before any decision is made. This typically means:

• Meeting with the employee to explain the concerns clearly
• Providing relevant evidence where appropriate
• Giving the employee a genuine opportunity to respond — including time to prepare and the option to have a support person present in appropriate circumstances
• Issuing a written warning or a show-cause letter if the situation warrants it, and recording the response

Keep notes of the meeting. A brief written record of who attended, what was discussed, and what the employee said is far more useful than memory if a claim is filed months later.

Where people get held up: Treating the meeting as a notification of the outcome rather than a genuine opportunity to respond. If the decision has already been made before the employee walks in the door, that is procedural unfairness, and it can convert an otherwise defensible dismissal into a successful unfair dismissal claim.

Step 4: Consider alternatives before deciding

Before confirming dismissal, ask honestly whether the outcome could be addressed another way. For underperformance: would additional training, clearer expectations, or a short performance improvement period resolve the issue? For conduct: is this a pattern or an isolated incident? For operational reasons: is there genuinely no other role or arrangement available?

If dismissal is still the right outcome, document why the alternatives were considered and ruled out. This demonstrates that the decision was proportionate, not reactive.

Step 5: Communicate the decision clearly

Issue a written termination letter. The letter should:

• State the decision and the effective date of termination
• Summarise the reason for the decision at a high level — specific enough to show the basis for it, not so detailed as to be argumentative
• Set out what the final pay will include and when it will be paid
• Cover practical matters: return of property, any post-employment obligations (confidentiality, non-solicitation if applicable), and how to obtain a separation certificate if needed

Keep the tone professional and factual. Avoid language that could be read as threatening, demeaning, or retaliatory — particularly important if there is any history of the employee raising complaints or concerns, as that context can support an adverse action claim.

Step 6: Calculate and process final pay

Final pay for a casual employee must include all amounts owed up to the termination date. Work through the following:

• Wages and casual loading: Pay all hours worked at the correct rate, including the casual loading and any applicable penalty rates or allowances under the relevant award or agreement.
• Notice: Casuals are not entitled to notice under the NES. You may choose to make a payment in lieu voluntarily if you want the engagement to end immediately and prefer to smooth the transition — if you do, record this clearly in the termination letter.
• Long service leave: Long service leave is governed by state and territory legislation, not the NES. In several jurisdictions, long-serving casual employees who have been employed on a regular and systematic basis may be entitled to a payout of accrued long service leave on termination. Check the rules that apply in the state or territory where the employee works.
• Deductions: Only make deductions that are lawful and properly authorised in writing. Deducting for general business costs or ordinary wear and tear on equipment without prior written authorisation is not permitted.

Most modern awards specify when final pay must be made — commonly by the next scheduled pay date, but sometimes sooner. Check the relevant award.

Where people get held up: Forgetting the casual loading or penalty rates in the final pay calculation, or assuming that because casuals have fewer entitlements, the final pay calculation is simple. Awards can be complex, and an underpayment — even a minor one — can result in a separate wage claim on top of any unfair dismissal or adverse action proceedings.

Step 7: Retain records

Keep all records related to the engagement and its ending:

• The casual employment contract and any variations
• Rosters, timesheets, and pay records
• Written warnings, performance notes, and investigation records
• Communications and meeting notes relating to the performance or conduct issue
• The termination letter and confirmation of final pay

Under the Fair Work Act 2009 (Cth), employers must generally retain pay records and certain employment records for seven years. Records relating to the dismissal itself may be needed if a claim is filed — the time limit for unfair dismissal applications is 21 days from the date of dismissal, but general protections claims can be filed within 21 days as well, and other proceedings may have longer limitation periods.

Claim risks to understand

Unfair dismissal

A casual who worked on a regular and systematic basis with a reasonable expectation of continuing employment, and who has completed the minimum employment period (six months, or 12 months for a small business employer), can apply to the Fair Work Commission for an unfair dismissal remedy. The Commission considers whether the dismissal was harsh, unjust, or unreasonable — which includes whether there was a valid reason, whether the employee was notified of the reason, and whether they were given an opportunity to respond. Remedies include compensation or reinstatement.

General protections (adverse action)

Every employee — including casuals — is protected from adverse action taken because they exercised a workplace right (such as making a complaint about pay or safety), engaged in industrial activity, or hold a protected attribute. General protections claims carry a reversed onus: once an employee establishes that a workplace right existed and adverse action was taken, the employer must prove the action was not taken for that reason. This makes documentation of the actual reason for dismissal especially important.

Discrimination

Dismissing a casual because of a protected attribute — race, sex, age, disability, pregnancy, family responsibilities, religion, and others — can ground a complaint under state and territory anti-discrimination legislation as well as under the general protections provisions.

Small business employers

If your business employs fewer than 15 people, the Small Business Fair Dismissal Code applies where the casual is eligible for unfair dismissal. The Code sets out the steps that constitute a fair dismissal process for small businesses — in particular, the requirements around warning an employee of underperformance before dismissing for that reason, and the process for summary dismissal in cases of serious misconduct. Keep written evidence of each step you took.

How Artificer Legal can help

Ending a casual engagement cleanly requires getting several things right at once: understanding whether the employee can bring an unfair dismissal or adverse action claim, confirming what the relevant award or agreement requires, structuring the process in the right order, and calculating final pay correctly. If any of those elements are uncertain, the risk of an avoidable claim rises.

An Artificer Legal employment law practitioner can assist by:

• Reviewing the casual's contract and the applicable award or enterprise agreement to identify any procedural obligations you must satisfy
• Advising on whether the employee is likely to be eligible for unfair dismissal or general protections claims, given the pattern of engagement
• Drafting a show-cause letter or termination letter that states the decision clearly without creating additional legal exposure
• Calculating or reviewing final pay entitlements, including long service leave where state law may apply
• Advising on the Small Business Fair Dismissal Code if your business headcount is under 15
• Representing your business if a claim is filed with the Fair Work Commission or another tribunal

Whether the employee had a genuine chance to respond

The step that most often turns a defensible dismissal into a successful claim is the conversation with the employee — specifically, whether that conversation was a genuine opportunity to respond or a formality conducted after the decision was already made. Procedural fairness at the point of communicating the concern and inviting a response is not a bureaucratic requirement: it is what separates a fair dismissal from an unfair one, even where the underlying reason was sound.

To summarise: confirm the casual's status and check the applicable award before taking any step; investigate conduct or performance issues properly; give the employee a genuine opportunity to respond; document each step; calculate final pay correctly (including checking state long service leave obligations for long-serving casuals); and retain records for at least seven years. Small business employers must also follow the Small Business Fair Dismissal Code. General protections claims can arise independently of unfair dismissal eligibility, so the reason for dismissal must be sound and documented regardless of how long the employee has worked for you.
