What is a Sick leave?

Updated 27 Jan 2026 5 min read

Sick leave in Australia is part of an employee's personal leave entitlement under the National Employment Standards. It allows employees to take paid time off when they are unwell or injured and unable to perform their duties. Full-time employees receive 10 days of paid personal/carer's leave per year.

Understanding sick leave

Sick leave in Australia is part of the broader personal leave entitlement under the National Employment Standards. It provides financial protection when employees are too unwell to work.

When to use sick leave

  • Personal illness (cold, flu, etc.)
  • Injury preventing work
  • Medical appointments
  • Mental health concerns

What employers need

  • Notice as soon as practicable
  • Expected duration of absence
  • Evidence if requested
  • Contact details if needed

Sick leave entitlements

The NES provides minimum sick leave entitlements for all permanent employees:

Minimum entitlements

Full-time: 10 days per year
Part-time: Pro-rata based on hours
Accrual: From first day of work
Accumulation: Year to year, no cap

Taking sick leave

When taking sick leave, employees must:

  • Notify promptly: Let employer know as soon as practicable
  • State the reason: That they're unwell (not detailed diagnosis)
  • Estimate duration: How long they expect to be absent
  • Provide evidence: If requested by the employer

Medical certificate requirements

Evidence requirements

Employers can request evidence for sick leave, but must be reasonable. The Fair Work Act allows medical certificates or statutory declarations as evidence. Check your award for specific requirements.

Acceptable evidence

  • Medical certificate from GP
  • Statutory declaration
  • Certificate from health practitioner
  • Pharmacy certificate (if accepted)

When to require evidence

  • Extended absences (2+ days)
  • Pattern of absences
  • As per award requirements
  • Consistent with policy

Common sick leave mistakes

Requiring diagnosis details

Employers cannot require employees to disclose their specific medical condition. A certificate stating they're unfit for work is sufficient.

Denying legitimate sick leave

If an employee has accrued sick leave and is genuinely unwell, employers cannot refuse to allow them to use it.

Pressuring employees to work sick

Pressuring employees to come in when sick can breach WHS obligations and may constitute adverse action.

Key takeaways

Sick leave is an important protection for employees and helps maintain workplace health by allowing unwell staff to recover without financial penalty. Employers must manage sick leave fairly and consistently.
