How Many Days Can You Take Sick Leave Without a Doctor’s Certificate?

The short answer

There is no specific national rule that says every employee must provide a medical certificate for one day of sick leave. However, your employer can ask for evidence if their workplace policy requires it, including for a single day. If you need proof for today or tomorrow, you can get a medical certificate online.

What Fair Work Australia says

• 1-day absence — most employers accept self-certification without a doctor’s note
• 2-day absence — some workplaces may request a certificate
• 3+ days absence — a medical certificate is typically required

Employers can legally require a medical certificate even for one day of absence, provided this is reasonable and consistent with the workplace policy. Check your employment contract or workplace policy.

Your entitlements

Under the Fair Work Act 2009, full-time employees are entitled to 10 days of paid sick leave per year, which accumulates over time. Part-time employees receive a pro-rata amount. Casual workers are not entitled to paid sick leave but may take unpaid leave.

Can your employer reject a medical certificate?

Employers cannot reject a valid medical certificate from a registered Australian doctor unless it appears fraudulent or lacks required details. If your employer unfairly denies your sick leave, you can lodge a complaint with Fair Work Australia.
