Medical Certificate Rules in Australia for Employees: What You Need to Know

What Is a Medical Certificate and Why Does It Matter?

A medical certificate is a written document issued by a registered healthcare professional confirming that an individual is unfit for work due to illness or injury. It is used as official proof when an employee needs to take sick leave or other medically related absences.

Employers request medical certificates to verify the legitimacy of an employee’s leave and to maintain workplace compliance. A certificate may be required even for a single day’s absence depending on the employer’s internal policy. Legally, it becomes essential when the leave period extends beyond two consecutive days or when stipulated by the employment agreement.

When Do You Need a Medical Certificate in Australia?

Employees typically need a medical certificate when:

• Taking sick leave or personal leave due to illness or injury
• Applying for stress or mental health leave
• Requesting extended time off
• Submitting documentation for WorkCover or injury-related claims
• Caring for a sick family member under carer’s leave

Understanding when a certificate is required helps avoid disputes with employers and ensures entitlements are accessed correctly.

Who Can Issue a Medical Certificate in Australia?

In Australia, medical certificates can be legally issued by:

• General Practitioners (GPs)
• Telehealth doctors registered in Australia
• Specialist doctors (e.g., psychiatrists, dermatologists)
• Allied health professionals (e.g., physiotherapists, psychologists) — in specific cases and within their scope of practice

Certificates issued by these professionals are accepted as valid when they include required details and are provided in good faith.

What Should a Valid Medical Certificate Include?

A valid medical certificate must contain:

• Full name of the patient
• Date of examination
• Date(s) the person is unfit for work
• Name, qualification, and signature of the doctor
• Provider number and clinic details (if applicable)

The certificate must be legible, written in English, and truthful. It should not include a diagnosis unless requested by the patient.

Is an Online Medical Certificate Legal in Australia?

Yes, medical certificates issued through online consultations with registered Australian doctors are legally valid. Telehealth services are regulated, and certificates issued during virtual consultations are accepted under Australian workplace laws, provided they meet the same standards as in-person ones.

These online certificates are especially useful for:

• Employees in remote areas
• Those unable to travel due to illness
• Quick access outside regular clinic hours

How to Get a Medical Certificate Online – Step-by-Step  

1. Choose a reputable online or telehealth platform
2. Book a consultation with a registered Australian doctor
3. Attend your virtual appointment via phone or video
4. Receive the medical certificate by email or patient portal

Always ensure the certificate includes all legally required details.

How Long Is a Medical Certificate Valid For?

The validity of a certificate depends on the dates mentioned by the doctor. Common durations include:

• 1–2 days for minor illness
• Up to 7 days for moderate conditions
• Longer periods for ongoing health issues, supported by reviews

Certificates should reflect the actual period the employee is unfit for work. Employers may ask for further documentation for long-term absences.

Can Employers Reject a Medical Certificate?

In general, employers must accept valid certificates issued by registered practitioners. However, they may reject a certificate if:

• It lacks required information
• It appears falsified or altered
• It comes from a non-recognised source

If disputes arise, employees can seek advice from Fair Work or legal support.

Your Rights Under Fair Work Australia

Fair Work Australia protects employee rights related to leave and evidence requirements. Key points include:

• Employees can take paid personal leave if sick
• Employers can request reasonable evidence such as a medical certificate
• Casual workers may be eligible for unpaid leave

Employees are not legally required to disclose the nature of their illness unless it affects their ability to work safely.

Common Misunderstandings About Medical Certificates

• “A certificate is only needed for long absences.” Some employers require one after a single day.
• “Online certificates aren’t valid.” They are legal if issued by a registered doctor.
• “I need to share my diagnosis.” No. Only proof of unfitness for work is required.

Using a Medical Certificate for Stress or Mental Health Leave

Mental health is a legitimate reason for taking medical leave. A medical certificate can be issued by a GP or psychologist after assessing the individual’s condition. These certificates are protected under the same laws as physical illness documentation.

Employees can take stress leave when mentally unfit to perform duties. Employers must treat this leave as confidential and valid under personal leave entitlements.

Special Cases – COVID, Carer’s Leave, or Bereavement

Some situations may require different approaches:

• COVID-19: Certificates for isolation or recovery based on current health advice
• Carer’s Leave: Supporting documentation when caring for a family member
• Bereavement: While not always requiring a certificate, employers may request proof of absence

What to Do If You’ve Lost Your Certificate

If a medical certificate is lost:

• Contact the issuing clinic or telehealth provider
• Request a re-issue or digital copy
• Avoid editing scanned copies — always get an original duplicate

Employers may not accept modified or incomplete documents.

Still Unsure? Here’s a Quick Summary

• Medical certificates are legal proof of illness or injury
• GPs and telehealth doctors can issue valid certificates
• Online certificates are accepted Australia-wide
• Always check your certificate for completeness and clarity
