Australian employers can ask for evidence for sick or carer's leave, but workplace policies, awards, and agreements can vary. This explainer keeps the legal and clinical claims narrow.

Clinical boundary
General information only. A doctor decides what is clinically appropriate for an individual case.
Claim: Australian employers can ask for evidence when an employee takes sick or carer's leave.
Fair Work guidance says employers can ask employees for evidence showing that leave was taken because of illness, injury, or caring responsibilities.
The same guidance says evidence can be requested for as little as one day or less off work.
Claim: Workplace policies, awards, and registered agreements can affect the evidence process.
Fair Work guidance notes that an award or registered agreement can specify when evidence must be given and what type of evidence is required.
That is why online certificate pages should not say that one document is accepted everywhere; the safer wording is that employer and institution policies may vary.
Claim: The type of evidence requested by an employer should be reasonable in the circumstances.
Fair Work guidance uses the reasonableness of the evidence request as the practical standard.
For online certificates, the useful details are the treating doctor's identity, registration details, dates, issue date, and a way for the document to be checked if a workplace queries it.
Claim: Medical Board guidance recognises telehealth as a way to provide clinical assessment when appropriate.
The Medical Board defines telehealth consultations as consultations using technology as an alternative to in-person consultations.
That does not mean every certificate request is appropriate online. It means the doctor must still decide whether the available information supports a safe decision.
Claim: A medical certificate supports workplace review but does not make the employer's policy decision.
The doctor's role is to assess clinical suitability and issue a certificate only where clinically appropriate.
The employer's role is to apply the relevant workplace policy, award, agreement, or HR process to the evidence provided.
