Are Online Medical Certificates Legal and Valid in Australia?

What Fair Work Requires as Evidence

The rules come from section 107 of the Fair Work Act 2009. Fair Work's guidance on notice and medical certificates explains them in plain English.

Medical certificates and statutory declarations are both examples of acceptable evidence. There are no strict rules on the type. What matters is that a reasonable person would accept you were genuinely entitled to the leave. It's a practical test, and a sick leave certificate is the evidence most workers use.

Fair Work frames its test around the quality of the evidence. That gives employers and workers one plain standard to apply whenever a certificate is questioned at work or in an email. Where a registered GP spoke with the worker, the employer can weigh that evidence against the standard. The wider medical certificate rules in Australia also cover notice, which comes before any request for evidence.

Which Body Sets Which Rule

"Legal" is really four questions. Four bodies answer them. Each speaks only for its own patch, and none of them speaks for the others.

A certificate can satisfy the doctor's professional duties and still meet resistance from a workplace with its own evidence rules. Different questions. Different owners.

Where the Medical Board Draws the Line

The Medical Board of Australia's telehealth guidelines cover how doctors consult remotely. The Board doesn't support healthcare given without a real-time direct consult. That consult can happen face to face, on video or over the phone.

So a phone consult fits. The guidelines set expectations for how doctors practise in every consultation type the Board covers. On their own, they don't decide whether a particular certificate is valid evidence.

What the 2023 Telehealth Update Changed

Ahpra announced the revised guidelines in May 2023, and they took effect on 1 September 2023. The change targeted asynchronous prescribing, where medicines are issued from a questionnaire with no real-time contact between doctor and patient.

Board chair Dr Anne Tonkin AO said at the time that telehealth "is here to stay". Ahpra's announcement also lists real-time telehealth consults as still permitted, including for first-time patients. So the Board didn't ban online care. It drew a line at care with no conversation behind it.

Why Questionnaire-Only Certificates Can Be Harder to Rely On

The guidelines single out text, email, live chat and online requests based on a health questionnaire. In those cases, the doctor has never spoken with the patient. That passage is written about medication requests, so it doesn't rule on certificates directly.

Still, if your employer questions a certificate from that kind of service, it may be harder to satisfy the reasonable person test. That's a separate issue from forgery, which is about whether a document was ever genuine in the first place. Using a fake medical certificate can be fraud, with consequences far beyond a questioned sick day.

What a Doctor Must Do Before Signing

The Board's code of conduct, Good medical practice, has a section on medical reports and certificates. It links community trust to doctors endorsing only what they reasonably believe to be true. It also asks them to make clear the limits of their knowledge, and not to give opinions beyond those limits. That duty is the doctor's. It can shape what a GP will certify once the consult is done.

The NSW Health Professional Councils Authority adds a practical note from the other side. In its guidance, the employer has the final say on whether to accept or reject a certificate. A legitimate document isn't automatically an accepted one. Hence the next section.

When an Employer or University Can Still Push Back

An award or registered agreement can say when you must give evidence and what type. Fair Work adds that the evidence requested must always be reasonable in the circumstances.

Universities run their own special consideration rules, and some need their own form completed by the doctor. Check the requirements before you book, so the certificate covers what's needed.

A Worked Example: The Manager Asks Questions

Say a worker emails a certificate after two days off. The manager writes back, doubtful, because it came from an online service and not a local clinic. Fair Work's guidance asks whether a reasonable person would accept, from the evidence, that the leave was real. The worker can point to a real-time consult with a doctor, the doctor's entry on Ahpra's register and any verification ID on the document. Keep the reply short.

If the workplace's award or agreement names a type of evidence, that wording matters too. Any request for evidence still has to be reasonable. That test looks at the worker's situation, not only the paperwork.

Signs a Telehealth Certificate Will Hold Up

Look for a doctor you can find on Ahpra's public register of practitioners. The certificate should show the consult date, the dates covered and the doctor's details. A way for your employer to check it is a bonus.

At OMC Health, the GP starts on the phone and judges when video is needed. Anyone under 18 consults with a parent or guardian present. An online medical certificate from OMC Health is issued only after that real-time consult, if the GP finds it appropriate.
