As per Australian guidelines, the standard requirements for a medical certificate are:

• Name and address of the doctor issuing the certificate
• Name of the patient
• Date on which the examination took place
• Date on which the certificate was issued
• Date(s) on which the patient is or was unfit for attendance
• A diagnosis is not usually required. If it is a requirement for a diagnosis to be provided, the doctor should inform the patient and only proceed to include the diagnosis following the express consent of the patient.
