Casual employees and your legal obligations as an Australian employer

If you hire casuals, the label comes with a legal package you cannot opt out of. The Fair Work Act 2009 (Cth) (the Fair Work Act) defines who is a casual employee, sets the pay and leave rules that apply to them, and gives long-serving casuals a pathway to permanent employment that you must respond to in writing. Get the basics wrong and you face back-pay claims, Fair Work Ombudsman (FWO) investigations, penalties, and unfair dismissal applications from people you thought were just casuals.

This guide sets out the obligations that apply to every Australian employer who engages casuals: confirming the engagement is genuinely casual, paying the right loading and meeting minimum engagement rules, giving the required information statements, handling leave and roster changes correctly, and managing the conversion pathway.

Who these obligations apply to

The obligations apply to any national system employer that engages a person as a casual employee, whatever the industry. The starting point is the definition, because it decides everything else.

Under s 15A of the Fair Work Act 2009 (Cth), a person is a casual employee only if both of these things are true:

No firm advance commitment: the employment relationship is characterised by an absence of a firm advance commitment to continuing and indefinite work.
Casual loading or rate: the employee is entitled to a casual loading, or a specific rate of pay for casuals, under an award, agreement or their contract.

Whether there is a firm advance commitment is assessed on the real substance, practical reality and true nature of the relationship, not just what the contract says. The FWO's guidance lists factors such as whether the employer can offer or not offer work, whether the employee can accept or reject work, whether it is reasonably likely future work will be available, and whether full-time or part-time employees do the same kind of work. A regular pattern of work on its own does not make someone permanent.

Two thresholds matter throughout this area:

Small business employer: an employer with fewer than 15 employees, counted at the relevant time under s 23 of the Fair Work Act. Casual employees count towards the 15 only if they are regular casuals.
Conversion and unfair dismissal timeframes: 6 months of employment for other employers, 12 months for small business employers, for both the employee choice pathway and the unfair dismissal minimum employment period.

Confirm the engagement is genuinely casual

Your first obligation is to make sure the person is actually a casual before you engage them as one. If the real substance of the relationship shows a firm advance commitment to continuing and indefinite work, the person is not a casual under s 15A, no matter what the contract says.

Practical signals that a role is genuinely casual include shift-by-shift offers of work the employee can accept or decline, no guarantee of hours, and no expectation that work will continue indefinitely. Signals that point the other way include a published roster that repeats week after week and permanent employees doing the same work alongside the casual.

Engaging someone as a casual when the relationship is really permanent has serious consequences: the employee may be entitled to paid annual leave and personal/carer's leave, notice of termination, and the other entitlements of a permanent employee, with those amounts recoverable as underpayments.

The Fair Work Act also prohibits sham arrangements. An employer must not knowingly make a false statement to persuade a permanent employee to become a casual doing the same work, and must not dismiss or threaten to dismiss an employee to re-engage them as a casual for substantially the same work (s 359B of the Fair Work Act). These are civil remedy provisions, which can lead to court penalties as well as compensation.

Pay the loading and meet minimum engagement rules

Casuals are paid by the hour, plus a casual loading instead of the paid leave and related entitlements that permanent employees accrue. Under many modern awards the loading is 25% of the base hourly rate for the classification. Clause 11.1 of the General Retail Industry Award 2020 is a typical example. The exact loading can differ between awards and enterprise agreements, so check the instrument that covers your business.

Awards also commonly set a minimum engagement for casuals. Under the General Retail Industry Award 2020, the minimum daily engagement for a casual is 3 hours (clause 11.2). If you roster a casual for a shorter shift than the award minimum, you generally still have to pay the minimum.

Overtime and penalty rates can apply to casuals on top of the loading. Whether they apply, and at what rate, depends on the award: when the casual works outside the ordinary span of hours, on weekends or public holidays, or beyond daily or weekly limits, the award's penalty and overtime tables typically apply. The award also sets the break rules, which apply to casuals the same way they apply to other employees.

Give the required information statements

When a casual starts, you must give them the Casual Employment Information Statement (CEIS) before or as soon as possible after they start. Under s 125B of the Fair Work Act, non-small-business employers must also give the statement again as soon as practicable after the employee has been employed for 6 months, after 12 months, and after each subsequent 12 month period. Small business employers must give it at the start and at the 12 month mark, but not at the 6 month mark.

The statement is published by the FWO and explains casual employment, including the employee choice pathway to permanent employment. Every new employee, casual or not, must also receive the Fair Work Information Statement.

A written offer or contract is not strictly required by the Fair Work Act, but it is the practical way to record that the engagement is casual and to set out how shifts are offered and accepted. At the time of engagement, the award will usually require you to inform the employee of the terms of their engagement, including that they are engaged as a casual.

Get leave entitlements right

Casuals do not accrue paid annual leave or paid personal/carer's leave. Instead, the casual loading compensates them for those entitlements. But casuals do have these leave entitlements under the National Employment Standards (NES):

Unpaid carer's leave: 2 days per occasion when a member of the employee's immediate family or household needs care or support because of illness, injury or an unexpected emergency (s 102 of the Fair Work Act).
Unpaid compassionate leave: 2 days per occasion on the death or serious illness of an immediate family or household member, unpaid for casuals (s 106 of the Fair Work Act).
Paid family and domestic violence leave: 10 days per year, paid, for casuals like all other employees.
Unpaid community service leave: available to casuals under the NES.

Casuals can also access unpaid parental leave and request flexible working arrangements, but only if they have been employed on a regular and systematic basis for at least 12 months and reasonably expect continuing employment on that basis. Keep records of each casual's actual pattern of work so you can apply these thresholds.

Handle roster changes and cancellations carefully

Because casuals have no guaranteed hours, you are not obliged to keep offering shifts. But once a shift has been offered and accepted, the picture changes. Many modern awards impose notice requirements or payment obligations when a rostered shift is cancelled or changed at short notice, and some require consultation before rosters are changed.

There is no single national rule on how much notice you need to give before cancelling a casual's shift. The answer comes from the award or agreement that covers the employee, read together with what your contract says. Check the award's rostering, consultation and payment clauses before you cancel a shift, and keep a record of when shifts were offered, accepted, changed and cancelled.

Manage the pathway to permanent employment

Since 26 August 2024, the NES has contained an employee choice pathway that replaces the old casual conversion request system for most employees. Under s 66AAB of the Fair Work Act, a casual who has been employed for at least 6 months (12 months if you are a small business employer) can give you a written notification that they believe they no longer meet the definition of a casual employee in s 15A.

When you receive a notification, you must:

Consult: discuss the change with the employee before responding, including whether it would be to full-time or part-time employment, the hours of work, and when the change would take effect.
Respond in writing within 21 days: your written response must reach the employee within 21 days of the notification (s 66AAC of the Fair Work Act).

If you accept the notification, your response must state the new status (full-time or part-time), the new hours, and the day the change takes effect. The change takes effect from the first day of the employee's first full pay period starting after your response, unless you agree otherwise.

You can refuse a notification only on limited grounds: the employee still meets the casual definition; there are fair and reasonable operational grounds for refusing (such as substantial changes being required to the way work is organised, or significant impacts on the operation of the business); or accepting the notification would breach a recruitment or selection process required by law. Your written response must give reasons, and refusals can be challenged, including before the Fair Work Commission.

The Fair Work Act protects the pathway. You must not reduce or vary an employee's hours, change their pattern of work, or terminate their employment to avoid your obligations or their right to change to permanent employment.

The consequences of getting it wrong

The FWO investigates breaches of the Fair Work Act and can take court action. The Act's civil remedy provisions allow courts to impose penalties on businesses and individuals, with the amount set according to the seriousness of the breach. Employees who are underpaid, including casuals who should have received loading, penalties, minimum engagement pay, or annual leave as permanent employees, can recover those amounts through the FWO or the courts.

Unfair dismissal is a particular risk with long-term casuals. A casual is protected from unfair dismissal only if they have completed the minimum employment period, which is 6 months for other employers and 12 months for small business employers (s 383 of the Fair Work Act). Critically, casual service counts towards that period only if the employment was as a regular casual employee and the employee had a reasonable expectation of continuing employment on a regular and systematic basis (s 384 of the Fair Work Act). A casual who works consistent, predictable hours week after week and is then cut off without process can therefore be in a position to bring an unfair dismissal claim.

Sham arrangement provisions carry their own exposure. Misrepresenting a permanent role as casual, or dismissing someone to re-engage them as a casual, can result in penalties as well as compensation for the employee.

Compliance checklist for engaging casuals

Work through these steps when you engage or review a casual:

Confirm status: assess the real relationship against s 15A before engaging someone as a casual, not just the label in the contract.
Check the award: identify the modern award that covers the role, the classification level, the casual loading, minimum engagement, penalty and overtime rates, and break rules.
Pay correctly: apply the loading to every hour, pay minimum engagement where it applies, and build the award rules into your rostering and payroll systems.
Give the statements: provide the Fair Work Information Statement and the Casual Employment Information Statement when the casual starts, and re-issue the CEIS at the times s 125B requires.
Document offers and acceptances: keep records of shifts offered, accepted, changed and cancelled, plus contracts and roster confirmations.
Handle roster changes by the award: check consultation, notice and payment obligations before cancelling or changing an accepted shift.
Watch the clock: diarise 6 month and 12 month anniversaries so you are ready for a notification under the employee choice pathway and the CEIS re-issue points.
Respond properly: if a casual notifies you under s 66AAB, consult, respond in writing within 21 days, and only refuse on the statutory grounds.
Review regularly: audit your casual workforce periodically for employees whose pattern of work has become regular and systematic.

Where a lawyer can help

Many casual employment issues turn on judgement calls, and that is where a workplace lawyer earns their keep:

Assessing casual status: applying the s 15A factors to a particular role and advising whether the engagement is defensible as casual, before you commit to a contract.
Responding to an employee choice notification: working out whether the refusal grounds in s 66AAC are available, and drafting a compliant written response.
Managing long-term casuals: assessing unfair dismissal and adverse action risk before you stop offering shifts to someone who has worked regular hours for years.
Drafting contracts and policies: putting together a casual employment contract, roster change policy and award mapping that match the instrument covering your business.
Defending an FWO investigation or claim: responding to an underpayment allegation, a sham arrangement complaint or an unfair dismissal application.

The obligation that catches most employers out

If you take one thing from this guide, make it the definition in s 15A. The contract can say casual, the pay can include a 25% loading, and the person can still be found not to be a casual because the real relationship carried a firm advance commitment to ongoing work. That finding unwinds everything: paid leave they should have accrued, notice they should have received, and a pathway to permanence you should have managed.

The cheapest compliance step available to you is a periodic review of your rosters. Look for anyone who has been offered and worked the same pattern of hours for six months or more, ask whether the relationship really lacks a firm advance commitment, and decide deliberately whether to keep that person casual, convert them, or change how you roster. Making that call on the documents, rather than letting it happen by default, is what keeps casual engagement defensible when the FWO or a former employee comes looking.
