When must an employer offer casual conversion in Australia?

Under the Fair Work Act, employers (other than small business employers with fewer than 15 employees) must offer casual conversion to a casual employee who: (1) has been employed for at least 12 months, and (2) has worked a regular pattern of hours during at least the previous 6 months that, on an ongoing basis, could continue without significant adjustment. The offer must be made in writing within 21 days of the 12-month anniversary.

What conditions must a conversion offer include?

A compliant offer must specify whether the conversion is to full-time or part-time, the days/hours of work, the new base rate (without the 25% casual loading), the effective date of conversion, and a reasonable timeframe for the employee to respond (typically 14-21 days). Continuity of service from the start of the casual engagement must be retained.

Can an employee refuse a casual conversion offer?

Yes. The employee can decline a conversion offer and continue as a casual on their existing terms. Refusing does not affect their role, future eligibility for conversion, or the employer's obligation to continue providing work. The employer should record the refusal and consider whether the conversion offer becomes appropriate again at a later point.

What happens to the 25% casual loading on conversion?

The 25% casual loading does NOT continue after conversion to permanent employment. The casual loading exists to compensate for the lack of paid leave and other entitlements. As a permanent employee, those entitlements are provided directly. The new base rate should reflect the rate WITHOUT the loading. Employees often see a lower headline hourly rate after conversion, but receive paid annual leave, personal leave, public holidays, and notice of termination as offsets.

Are small business employers required to offer casual conversion?

Small business employers (fewer than 15 employees) are NOT required to offer casual conversion under the Fair Work Act 2009 amendments. However, small business employers may still receive a request for conversion from a casual employee, which they must respond to in writing. Small business employers may also voluntarily offer conversion — many do, to retain experienced casuals on more stable terms.

Last verified: 1 July 2025

Eligibility: 12+ months as casual + regular pattern over the last 6 months. Required for employers with 15+ employees; voluntary for small businesses.

What "regular pattern" means

The Fair Work Act doesn't define "regular pattern" precisely. Recent FWC and Federal Court decisions look for:

Same days of the week worked over multiple weeks
Similar hours each shift / each week
Predictability — the employee can reasonably expect the work to continue
Pattern observed over at least the last 6 months

Casual employees with a clearly regular pattern who haven't been offered conversion may have grounds to escalate via the Fair Work Ombudsman or the Fair Work Commission.
