Casual conversion in Australia has been replaced by the employee choice pathway. Since 26 August 2024, under the Fair Work Legislation Amendment (Closing Loopholes No. 2) Act 2024, an eligible casual employee can give their employer written notice asking to move to full-time or part-time employment after 6 months of service (12 months for a small business under 15 employees). The employer has 21 days to respond in writing, must consult first, and can only refuse on fair and reasonable operational grounds or where the employee does not meet the eligibility test. Getting this wrong risks Fair Work penalties and back-pay claims.
This guide walks an Australian employer through exactly what changed, who is eligible, how to respond, when you can refuse, and how labour hire arrangements interact with the new rules. It references current Fair Work Ombudsman guidance.
A snapshot of what changed
Before the Closing Loopholes No. 2 Act, employers had an obligation to offer conversion to eligible casuals after 12 months. The initiative sat with the employer. From 26 August 2024 the logic flipped. The employee now has the right to notify the employer that they want to convert, provided they meet the eligibility test. The employer must respond in writing within 21 days after consulting the employee. The 2024 changes also introduced a new legal definition of a casual employee focused on whether there is a “firm advance commitment” to continuing work, weighed across the totality of the employment relationship rather than the contract alone.
For Australian employers who run blended workforces – a core team plus a rolling casual pool, or a host site that uses labour hire – this is a material shift. Compliance is now reactive rather than scheduled, and the evidence of how the work is actually performed matters as much as the paperwork.

The new casual definition: What the test actually says?
The Fair Work Act now defines a casual employee by reference to section 15A. An employee is a casual if, when they start employment, the employment relationship has no firm advance commitment to continuing and indefinite work, and they are entitled to a casual loading or specific casual pay rate under an award, registered agreement, or contract.
“Firm advance commitment” is assessed across the whole relationship. The Fair Work Act lists factors including:
- Whether the employer can elect to offer or not offer work, and whether the employee can accept or reject it.
- Whether it is reasonably likely the work will continue, given the nature of the business
- Whether there are full-time or part-time employees doing the same kind of work
- Whether the employee has a regular pattern of work (though a regular pattern alone does not make them permanent)
The short version: you cannot turn a genuinely permanent role into a casual role by writing “casual” in the contract. Courts and the Fair Work Commission look at the actual arrangement.

Why this matters for warehouse, manufacturing, and food processing employers?
Blue-collar operations often employ the same casuals week after week on predictable shifts. Under the new test, the question is not whether the contract says “casual”. It is whether, looking at the totality, there is a firm advance commitment. A forklift operator who has worked the same Monday to Friday roster for 18 months is likely to trigger scrutiny even if every shift is “offered and accepted”. The safer approach is to review rosters, rotate casuals through genuine peak-and-trough patterns, and respond promptly to any conversion notice.
When the employee choice pathway applies
An employee can issue a conversion notice if all the following are true:
- They have been employed for at least 6 months (or 12 months if the employer is a small business with fewer than 15 employees at the time of the notice).
- They believe they no longer meet the requirements of the casual employee definition in section 15A. In other words, they believe there is a firm advance commitment to ongoing work, looking at how the job is actually being performed.
- They have not recently been through the process. An employee generally cannot give a new notice within 6 months of a previous notice, or while a dispute about a previous notice is on foot.
The notice must be in writing and state that the employee believes they no longer meet the casual definition.
Counting employees for the small business threshold
A “small business” in the Fair Work system means fewer than 15 employees, counted on a headcount basis, including regular and systematic casuals. Associated entities count together. If your headcount sits around 14 to 16, keep a dated list. The threshold applies at the time the notice is given, not at the time the employee was hired.
The 21-day response clock and what employers must do
Once a written notice is received, the employer has 21 days to respond in writing. Before responding, the employer must consult with the employee. The consultation covers:
- Whether the move would be to full-time or part-time employment
- What the hours of work would be
- When the change would take effect
The response must say whether the employer accepts or refuses, and if it refuses it must set out the specific grounds.
Step by step: the compliant process
- Log the notice the day it is received. Date-stamp it and store it with the employee’s file.
- Review eligibility immediately. Check length of service, current headcount if you sit near the small business threshold, and any prior notices.
- Assess the actual work pattern. Is there a firm advance commitment to ongoing work? Look at 6 months of rostering, not just the contract.
- Schedule consultation within the first week. Meet with the employee, discuss full-time vs part-time, proposed hours, and effective date.
- Decide and draft the response. Accept, or refuse with specific grounds. Keep it factual.
- Issue the written response before day 21. Send it, keep the dispatch record, and file it.
- If accepted, update payroll and contract. Remove casual loading, set new hours, issue a new letter of appointment, update super and leave accruals.
- If refused, provide the grounds in writing. Keep a clear paper trail if the refusal is challenged.

When you can refuse conversion
An employer can refuse a notice only if:
- The employee still meets the casual definition at the time the notice is given. In plain terms, the work pattern genuinely is casual. You will need evidence.
- There are fair and reasonable operational grounds that make conversion unworkable. The Fair Work Act and the Ombudsman name specific examples:
- Substantial changes would be required to how the business organises its work
- There would be significant impact on the operation of the business
- Substantial changes to the employee’s terms would be needed to keep the employer compliant with an award or agreement
- Accepting would mean the employer does not comply with a recruitment or selection process required by law (for example, merit-based processes in the public sector).
Weak reasons that do not count on their own:
- “We prefer to keep the workforce flexible”
- “Conversion is administratively inconvenient”
- “The worker has never complained”
- “Our competitors all use casuals”
If you refuse, you must state the specific reason in the written response. “Operational reasons” without detail will not satisfy a Fair Work audit.
Worked example: a Melbourne warehouse operator
A warehouse in the western Melbourne corridor runs a 30-person casual pool. One picker, employed for 9 months, issues a conversion notice. The employer:
Confirms length of service: 9 months, non-small business, so the 6-month threshold is cleared.
- Reviews rostering data: the picker has worked every Monday to Friday 6am to 2pm shift for the past 6 months.
- Concludes the firm advance commitment test is not met by the casual status on current patterns.
- Schedules a consultation meeting, discusses part-time at 38 hours, accepts the notice, issues a new appointment letter for 5 May 2026, removes the 25 per cent casual loading, and commences standard leave accrual.
The same employer receives a notice from a second picker who has worked intermittently across 12 different shift types, averaging 2 shifts per week with gaps of up to 3 weeks. Here the employer can legitimately refuse on the ground that the employee still meets the casual definition, documenting the variable pattern in the written response.
Disputes: what happens if the employee challenges a refusal
If a refusal is disputed, the parties must first try to resolve it at the workplace. If that fails, either party can refer the dispute to the Fair Work Commission. The Commission can conciliate, mediate, and in some cases make orders, including orders that the employee be treated as permanent from a specified date. Penalties under the Fair Work Act for contraventions of the casual conversion rules can apply.
This is where documentation earns its keep. A clear written notice, dated consultation meeting notes, rostering evidence, and a specific written refusal give an employer a defensible position. Verbal refusals, delayed responses, or boilerplate “operational reasons” do not.

How labour hire interacts with the new rules?
This is where host businesses are most exposed to risk they did not create. Three rules to remember.
1. The labour hire agency is the employer
Under a labour hire arrangement, the worker is employed by the agency, not the host. The 21-day response obligation sits with the agency. A conversion notice from an on-hire casual lands with the agency first.
2. The host site evidence still matters
The casual definition looks at the actual work pattern. The pattern is set at the host site. If a host books the same labour hire worker for the same shift for 12 months, the agency has a conversion problem even if the host never sees the paperwork. Agencies that take the risk seriously will consult the host before responding to make sure rostering evidence and site context is captured.
3. The labour hire agreement should set expectations
A well-drafted labour hire agreement should:
- Identify each on-hire worker as casual or ongoing at the point of placement
- Require the host to notify the agency of any long-running, regular, and systematic placements
- Require the host to share rostering data on request so the agency can respond to conversion notices
- Make clear that any conversion decision sits with the agency

Common employer mistakes and how to avoid them
Mistake 1: Treating the new rules as an HR-only issue.
The evidence that determines outcomes is operational, not HR. Rosters, timesheets, and actual shift patterns decide whether the casual definition is met. Operations managers should be looped in.
Mistake 2: Assuming labour hire casuals are someone else’s problem.
If a host site routinely rosters the same on-hire worker on the same shift pattern, the host is shaping the evidence that will drive a future conversion obligation for the agency. Poor labour hire practice at the host creates dispute risk for both parties.
Mistake 3: Missing the small business headcount.
An employer sitting at 14 employees this month but 16 next month is a non-small business employer at that point. The 6-month threshold applies. Track your headcount monthly.
Mistake 4: Verbal refusals or generic written responses.
The Fair Work Ombudsman publishes a response template. Use it. “Operational reasons” on its own will not survive scrutiny.
Mistake 5: Ignoring the 21-day clock.
A silent employer loses the procedural ground. Calendar every notice from day 1.
Mistake 6: Forgetting the casual loading reversal.
If you accept a conversion, casual loading comes off. Payroll must adjust and a new appointment letter should be issued the same week.
Checklist: what every Australian employer should have in place
- A register of all casual employees with start date, current service length, and a small business status flag
- A process for receiving and date-stamping a conversion notice
- A 21-day response template aligned with the Fair Work Ombudsman guidance
- Roster and timesheet data kept for 12 months minimum
- Consultation meeting notes template
- A decision record template for accept or refuse, with grounds
- A payroll checklist for accepted conversions (casual loading off, leave accrual on, contract update)
- A labour hire agreement clause covering conversion notifications (for host businesses)
- A quarterly review of casual rostering patterns to spot where the definition is at risk of being breached
Print this, stick it on the operations board, and your business is in a defensible position.
Takeaways
- Casual conversion has been replaced by an employee-led choice pathway. Employers no longer schedule offers at 12 months. They respond to notices.
- Eligibility is 6 months of service, or 12 months if the employer is a small business under 15 employees.
- The employer has 21 days to respond after consulting the employee, and refusal must cite specific operational grounds or the continued application of the casual definition.
- The new casual definition looks at the totality of the employment relationship. Contract labels alone no longer settle the question.
- Labour hire does not insulate host businesses. The host’s rostering practices shape the agency’s conversion risk.
- Document every step. A conversion dispute is won or lost on the paper trail.
Frequently Asked Questions
Casual conversion has been replaced by the employee choice pathway under the Closing Loopholes No. 2 Act 2024. An eligible casual employee can give written notice to their employer asking to convert to full-time or part-time employment. The employer must consult the employee and respond in writing within 21 days. The old employer-initiated offer process is no longer the main mechanism.
The Fair Work Act casual definition changed on 26 August 2024. The employee choice pathway started for non-small business employers on 26 February 2025 and for small business employers on 26 August 2025. As of 2026 the pathway applies across all Australian employers.
Under the employee choice pathway the direction of travel is reversed. The employee initiates the notice. An employee is not obliged to issue a notice, and they can remain casual if they prefer the flexibility and casual loading. Older offer-based provisions still apply in limited transitional cases but are being phased out.
Casual loading is 25 per cent under most modern awards in Australia. The loading compensates casuals for the absence of paid leave and notice entitlements. Always check the applicable modern award or registered agreement for the specific role, as a small number of awards use different figures.
There is no fixed cap on casual hours in the Fair Work Act, but the regular pattern and firm advance commitment test applies. A casual working 38 hours a week on the same roster for 6 months is exposed to a conversion notice. Weekly hours must also meet the applicable modern award provisions for minimum engagement and overtime.
A slowdown alone is not a reliable refusal ground. The Fair Work Ombudsman lists fair and reasonable operational grounds such as substantial changes to how work is organised or a significant impact on business operations. You must set out the specific grounds in the written response, with evidence. A generic “business is slow” response will not survive review.
