Guide for casual employees on when medical certificates are required and your entitlements under Australian workplace law.
Casual employment in Australia is different from full-time or part-time work. You don't get paid sick leave — but that doesn't mean medical certificates don't matter. Some employers still require them, and having documentation protects you. Here's what casual workers need to know.
Casual employees don't receive paid sick leave under the Fair Work Act. However, you're entitled to 2 days of unpaid carer's leave per occasion, and unpaid compassionate leave. Your casual loading (typically 25%) is meant to compensate for the lack of leave entitlements.
Tips
Even without paid sick leave, your employer may request a medical certificate to: justify rescheduling shifts, document why you missed a rostered shift, support unfair dismissal claims if they try to let you go for being 'unreliable', or if you're applying for conversion to permanent status.
Tips
The process is the same as for any employee. See a doctor or use telehealth. The certificate states you were unfit for work on specific dates. Even if you're not getting paid for the day, having documentation shows you had a legitimate reason for your absence.
Tips
You can't be fired for a genuine illness. However, casual employment can be ended without notice. Having medical certificates documents that your absences were legitimate.
Yes, there's typically a cost for the consultation. Telehealth services like InstantMed offer certificates from $19.95 — often cheaper than an in-person GP visit.
There's no 'unpaid sick leave' entitlement, but you can simply not work. Having documentation helps protect your position with your employer.
You're never obligated to work while genuinely unwell. If pressured, document the conversation and contact Fair Work if necessary.
