Full-Time Casual Employment in Australia, employer Obligations Under the Fair Work Act

"Full-time casual" is a phrase you will hear constantly on Australian worksites, and it is a trap. If you have a worker who is rostered most days, works a stable pattern at close to 38 hours a week and has done so for a year or more, yet is paid as a casual with a loading and no leave, you are carrying a legal risk. The phrase describes a practical situation, not a legal category. The law asks a different question: does the relationship genuinely lack a firm advance commitment to continuing and indefinite work?

Getting that question wrong can mean backpay of annual leave and personal leave going back years, unfair dismissal claims, and penalties. Since 26 August 2024 the test has also changed in ways many employers have not absorbed. This guide sets out the obligations that apply when you engage or keep casuals working near full-time hours: getting the classification right, paying the correct loading and penalties, managing leave and super, running the employee choice pathway to permanent employment, and ending engagements safely.

Who These Obligations Apply To

These obligations apply to every national system employer covered by the Fair Work Act 2009 (Cth) (the Act), which is most private-sector businesses in Australia. There is no turnover or size threshold for the classification rules themselves. Size only changes the timing and thresholds in two specific places, and you need to know which camp you are in from the start:

Small business employer: fewer than 15 employees. The 6-month triggers below become 12 months.
Non-small business employer: 15 or more employees. The shorter 6-month triggers apply.

Two situations should put you on notice that a casual arrangement needs a closer look:

a casual averages 30 or more hours a week on a fixed or near-fixed roster, or
a casual fills a core, ongoing role that permanent staff also perform, or has been doing so for more than a year.

Classify Correctly: What "Casual" Means Under the Fair Work Act

The starting point is s 15A of the Fair Work Act 2009 (Cth). An employee is a casual only if two things are both true: the employment relationship is characterised by an absence of a firm advance commitment to continuing and indefinite work, and the employee receives a casual loading or a specific casual rate under an award, enterprise agreement or contract.

The phrase "firm advance commitment" is the heart of the test. In WorkPac Pty Ltd v Rossato [2021] HCA 23 the High Court confirmed that the essence of casual employment is the absence of a firm advance commitment as to the duration of the employment or the days and hours the employee will work. That decision, and the litigation around it, prompted Parliament to put the definition on a statutory footing.

The amendments that took effect on 26 August 2024 made the test more demanding in practice. Whether a firm advance commitment exists is now assessed by reference to the real substance, practical reality and true nature of the relationship, and it can arise from a mutual understanding or expectation between you and the employee even if that understanding is not written into the contract. The factors a court or the Fair Work Commission will weigh include:

whether you can genuinely elect to offer or not offer work, and the employee can genuinely accept or reject it, looking at how it happens in practice rather than what the contract says,
whether, given the nature of your business, it is reasonably likely there will be continuing work of the kind the employee performs,
whether you have full-time or part-time employees doing the same kind of work, and
whether there is a regular pattern of work.

One point in your favour: a regular pattern of work alone does not make someone permanent. The statute is explicit that a casual can work a regular pattern and still be a casual if there is no firm advance commitment. But a regular pattern combined with the other factors, such as a roster set months in advance, shifts assumed rather than genuinely offered, and permanent staff doing identical work, will point strongly the other way.

There is also a timing rule worth understanding. Once someone starts as a casual, they remain a casual until a specified event occurs: their status is changed under the conversion rules in Division 4A, the Commission orders a change, an award or agreement changes their status, or they accept an offer of permanent employment. In other words, the clock does not restart every week, and status does not drift on its own.

Pay the Right Rate: Loading, Penalties, Overtime and Hours

Casual pay is loading plus penalties, and errors here are the most common source of claims. Modern awards typically set the casual loading at 25%, although the figure varies by award, and award-free casuals must receive at least the national minimum wage plus the casual loading set in each year's annual wage review. Your payroll needs to apply the base rate, the loading, penalty rates for evenings, weekends and public holidays, and any casual overtime thresholds in the relevant award or enterprise agreement.

The National Employment Standards (the NES) also cap hours. Under s 62 of the Act, an employer must not request or require an employee to work more than 38 hours a week, or the employee's ordinary hours if less, unless the additional hours are reasonable. Employees can refuse unreasonable additional hours. That cap applies to casuals as much as to anyone else, even though their ordinary hours are not fixed in the same way.

Awards commonly add their own rules on top: minimum engagements per shift, often around three hours, minimum notice for changing or cancelling shifts, and minimum time between shifts. If you are running a high-hours casual on a roster you keep changing at short notice, you can breach the award even when the base pay is right.

Accurate records are part of this obligation. Time and wage records and payslips that identify the base rate, the loading and the penalties paid are not just paperwork. If a misclassification claim ever lands, those records are what show the loading was identifiable and actually paid.

Get Leave, Super and Other Entitlements Right

Casual status changes what your workers are owed, and high-hours casuals are where the misunderstandings concentrate:

Paid annual leave and paid personal or carer's leave: casuals do not accrue either. The casual loading is compensation for the loss of these entitlements. For contrast, a permanent employee accrues four weeks of annual leave a year and 10 days of paid personal or carer's leave per year of service, expressly excluding periods of casual service under s 96 of the Act.
Compassionate leave: casuals are entitled to two days of unpaid compassionate leave per occasion, where the leave is paid for permanent employees.
Paid family and domestic violence leave: this one applies to casuals in full. Every employee, including casuals, is entitled to 10 days of paid family and domestic violence leave in each 12-month period, available from their first day, and a casual is paid for the hours they were rostered to work.
Superannuation: eligible casuals must receive superannuation guarantee on their ordinary time earnings from the first dollar. The old $450-per-month earnings threshold was removed from 1 July 2022, so a casual working a few hours a week is entitled to super just like a full-timer.
Long service leave: this is state and territory law, not the Act. In most states and territories casuals can accrue long service leave based on continuous service with the same employer, so check the rules in the state where the work is performed.
Notice and redundancy: the National Employment Standards provisions on notice of termination and redundancy pay do not apply to casual employees. But your contract or enterprise agreement can still require notice, so read those terms before you end an engagement.

Run the Employee Choice Pathway Properly

Casual conversion is no longer the offer-and-request system many articles still describe. From 26 August 2024 the Act replaced it with the employee choice pathway under Division 4A, and the transitional arrangements for casuals engaged before that date ran out on 26 August 2025.

Under the current rules, a casual who believes they no longer meet the definition of casual employee can give you a written notification that they want to change to full-time or part-time employment. They can do this once they have been employed for at least six months, or 12 months if you are a small business employer, and they have not had a previous notification refused in the last six months.

Your obligations when a notification arrives are specific and time-limited:

Consult first: Before responding you must discuss the change with the employee, including whether they would become full-time or part-time, what their hours would be, and when the change would take effect.
Respond in writing within 21 days: Accept the change, or decline it with reasons. There is no third option and no silent option. If you accept, your response must set out the new employment status, the new hours and the start date, which is the first day of the first full pay period after your response unless you agree otherwise.
Only limited grounds for refusal: You can decline only if the employee still meets the casual definition, if there are fair and reasonable operational grounds (for example, substantial changes to how work is organised, significant impacts on the operation of the business, or changes to conditions needed to comply with an award or agreement), or if accepting would mean breaching a recruitment or selection process required by law.

There are also protections you cannot sidestep. You must not reduce or vary an employee's hours, change their pattern of work, or terminate their employment to avoid the pathway, and you cannot take adverse action against them for giving a notification or participating in a dispute. If the change cannot be agreed, the Fair Work Commission can mediate, conciliate and ultimately arbitrate the dispute, and a Commission order can change the employee's status.

You should also give each casual the Fair Work Ombudsman's Casual Employment Information Statement at engagement, and again when they move to permanent employment, so the pathway is visible from day one.

End High-Hours Casual Engagements With Unfair Dismissal in Mind

Ending a high-hours casual arrangement is where employers assume they are safe because casuals have no notice or redundancy entitlements under the NES. That is only half the picture.

Unfair dismissal protection can apply to casuals. Service as a casual counts towards the minimum employment period only where the employment was regular and systematic and the casual had a reasonable expectation of continuing employment on that basis. The minimum employment period itself is six months, or 12 months for a small business employer. A casual who has worked a predictable roster for years and been told the work is ongoing can clear both hurdles, and a dismissal that is harsh, unjust or unreasonable can then lead to reinstatement or compensation.

There is also a sham arrangement rule that catches employers directly: you must not dismiss an employee in order to re-engage them as a casual performing the same or substantially the same work. That is a civil remedy provision in its own right, quite apart from any unfair dismissal claim.

Before ending any long-serving, high-hours casual engagement, check your contract and any enterprise agreement for notice terms, review the roster history and any assurances given about ongoing work, and treat the ending with the same care you would for a permanent employee.

What Happens When You Get It Wrong

The exposure is not theoretical. If a court or the Commission finds a worker was permanent in substance, the claim typically runs for the whole period of service: backpay of annual leave at four weeks per year, 10 days of personal or carer's leave per year, and in some cases other NES entitlements, plus interest. Unfair dismissal remedies can add reinstatement or up to six months of compensation, and contraventions of civil remedy provisions can attract penalties.

One mitigation exists. Under s 545A of the Act, if a court finds an employee described as casual was not in fact a casual, it must reduce any entitlement awarded by the identifiable casual loading the employee was paid. This is a genuine protection, but it only works if the loading was identifiable in the contract and payslips and was actually paid for the period in question. It is not a cure-all, and it does nothing for unfair dismissal claims. Treat it as a reason to keep clean records, not as permission to misclassify.

Compliance Checklist

Work through each item to keep your casual engagements compliant:

Audit your casuals averaging 30 or more hours a week or working regular, predictable patterns, and apply the s 15A test to the reality of each role, not the contract label.
Make sure shifts are genuinely offered and accepted engagement by engagement, rather than assumed or imposed.
Check base rates, loadings, penalties and overtime against the relevant award or enterprise agreement and reflect them in payroll settings.
Diarise the 21-day response deadline whenever an employee choice notification arrives, and consult before you respond.
Keep time and wage records and payslips that identify the loading separately.
Issue written contracts that state the casual basis, and give casuals the Casual Employment Information Statement.
Before ending a high-hours casual engagement, assess unfair dismissal exposure and any contractual notice obligations.

Where a Lawyer Can Help

Classification is a judgement call, and it is the one place a modest upfront review saves the most money. A lawyer can audit your casual workforce against the current s 15A test, redraft casual contracts so the basis of engagement is genuine and documented, walk you through a difficult employee choice notification, and defend a misclassification, underpayment or unfair dismissal claim if one lands.

The Classification Question to Answer This Week

The change that matters most is the 2024 shift in the definition. Because the test now looks at the real substance of the relationship over time, the contract label and the "no firm advance commitment" clause are no longer a shield on their own. A worker on a fixed 38-hour weekly roster that you set months in advance, who never declines shifts and does the same work as your permanent staff, is a misclassification claim waiting to happen, no matter what their contract says. This week, pull the list of casuals working 30 or more hours on regular rosters and apply the factors in s 15A to each one. For anyone who fails the test, the question is not whether to convert them but how quickly you can do it properly, and that is exactly the point where advice pays for itself.
