And how to verify a real medical certificate safely. Australian employers, HR teams, and payroll managers occasionally receive medical certificates that don't quite look right. This guide explains the warning signs of a fake medical certificate, what the law says, and how to confirm whether a certificate is genuine — including how to verify a DoctorsNote certificate in under 10 seconds.
How to spot a fake medical certificate
Five warning signs that a medical certificate may require closer review:
- No named doctor. A valid Australian medical certificate must name the certifying GP. "Telehealth Clinic" or a logo alone is not enough.
- No AHPRA registration number. Every certifying doctor in Australia holds an AHPRA registration (format: MED followed by 10 digits). If the number is missing, looks wrong, or won't resolve on the public AHPRA register, the certificate should be checked carefully.
- No verification method. Modern Australian medical certificates increasingly include a QR code or reference number that links back to the issuer. A certificate with no way to confirm it independently is harder to trust.
- Inconsistent formatting or dates. Mismatched fonts, misaligned headings, dates that don't match the day of the week, or signatures that look pasted in are common signs of a tampered document.
- Claims that cannot be checked later. If the issuing service has no contact details, no business registration, and no public record, the certificate's authenticity is difficult to confirm.
None of these on their own automatically mean a certificate is fake. They are warning signs that the certificate should be checked carefully, in line with your workplace policy.
What is a fake medical certificate?
A fake medical certificate is a document that presents itself as a doctor's certificate but was not issued by a registered Australian medical practitioner following a genuine clinical assessment. Common types include:
- Templates downloaded online and filled in by the patient
- Edited or altered genuine certificates (changed dates, names, or duration)
- Documents issued by services that are not operated by AHPRA-registered doctors
- Forged signatures or AHPRA numbers
Under Australian law, presenting a forged or altered medical certificate to an employer can be treated as fraud. The legal position is covered in the next section.
Is a fake medical certificate illegal in Australia?
Yes. In Australia, knowingly presenting a forged or altered medical certificate can constitute fraud under state and territory criminal law, and may breach an employee's contract of employment. Employers may also rely on this when responding to suspected misconduct.
However, an employer should not act on suspicion alone. The Fair Work Ombudsman's guidance is that employers should:
- Follow their workplace policy on suspected fraudulent evidence
- Give the employee an opportunity to respond
- Where appropriate, seek independent legal or HR advice
- Avoid taking adverse action without proper process
A certificate that looks unusual is not proof of fraud. It is a reason to make further enquiries — calmly, in writing, and through proper channels.

How DoctorsNote verification confirms a real certificate
Every DoctorsNote certificate issued from April 2026 onwards is independently verifiable. This is powered by CASI — our Clinical AI Systems Infrastructure — which binds each certificate to the certifying doctor, their AHPRA registration, and the exact moment of issuance.
When a DoctorsNote certificate is verified, the system confirms:
- The certificate reference exists in the DoctorsNote clearance registry
- The certificate was issued by DoctorsNote (not a PDF made elsewhere)
- The certificate is linked to a named, AHPRA-registered reviewing GP
- The issue date, certificate type, and status can be checked
- The certificate has not simply appeared as an unverifiable PDF
How an employer verifies a DoctorsNote certificate:
- Scan the QR code on the certificate PDF, or
- Visit doctorsnote.com.au/verify/ and enter the reference number
The result displays in under 10 seconds. No phone call. No waiting on the doctor's clinic. No guesswork.
Certificates issued before April 2026 carry their original QR codes and reference numbers. For verification of an earlier certificate, employers can contact doc@doctorsnote.com.au with the reference number.
How to get a real medical certificate online

Available certificate types:
Standard certificates are $14.95, issued within 24 hours if clinically appropriate, and independently verifiable by your employer.

What employers can and cannot ask for
Under the Fair Work Act 2009 (Cth) and the Australian Privacy Principles, employers in Australia have specific rights and limits when reviewing a medical certificate.
Employers can:
- Request evidence for personal or carer's leave under the Fair Work Act's "reasonable person" standard (s.107)
- Confirm that a certificate appears genuine and was issued by an AHPRA-registered practitioner
- Use a public verification system (such as a QR code or issuer's verification page) to confirm authenticity
- Look up the certifying doctor on the public AHPRA register
- Follow their workplace policy where a certificate appears irregular
Employers cannot:
- Demand a diagnosis or specific medical details. An employee's right to medical privacy is protected under the Privacy Act 1988 (Cth)
- Contact the certifying GP for clinical information without the employee's consent
- Refuse paid personal or carer's leave to a permanent employee who provides valid evidence meeting the reasonable person standard
- Take adverse action against an employee for exercising their leave entitlements — this may breach general protections under the Act
If a dispute arises, the Fair Work Ombudsman is the appropriate regulator: fairwork.gov.au or 13 13 94.
What employees should know
If your medical certificate has been questioned by your employer:
- Stay calm. A request to confirm a certificate is not, on its own, an accusation of fraud.
- Provide the certificate's verification reference or QR code if available.
- For a DoctorsNote certificate, your employer can verify it in under 10 seconds at doctorsnote.com.au/verify/.
- If your employer contacts the certifying service directly, the service can confirm whether the certificate is genuine without disclosing your diagnosis.
- If you believe your employer is acting unreasonably, the Fair Work Ombudsman provides free guidance.
A genuine medical certificate from an AHPRA-registered GP is valid evidence of personal or carer's leave under Australian law. You are not required to disclose your diagnosis to your employer.
Frequently asked questions
How can an employer tell if a medical certificate is fake?
Warning signs include no named doctor, no AHPRA registration number, no verification method, inconsistent formatting, and claims that cannot be checked later. None of these on their own confirm a certificate is fake — they are reasons to check carefully.
Can an employer verify a medical certificate in Australia?
Yes. Where the certificate carries a QR code or verification reference, the employer can confirm authenticity directly through the issuer. Employers can also look up the certifying doctor on the public AHPRA register. DoctorsNote certificates can be verified at
doctorsnote.com.au/verify/.
Does a medical certificate need an AHPRA number?
A medical certificate must be issued by an AHPRA-registered medical practitioner. The AHPRA registration number is the public proof of that registration and should appear on the certificate.
Can an employer ask for a diagnosis?
No. Under the Australian Privacy Principles, an employer is not entitled to know the nature of an employee's illness or injury — only that the employee was genuinely unfit for work.
Are online medical certificates valid in Australia?
Yes, provided the certificate is issued by an AHPRA-registered Australian GP following a genuine clinical assessment. Online certificates meet the Fair Work Act's "reasonable person" evidence standard on the same basis as in-person certificates.
What should an employee do if their certificate is questioned?
Provide the certificate's verification reference or QR code. For DoctorsNote certificates, employers can verify in under 10 seconds online. If a dispute continues, the Fair Work Ombudsman provides free guidance.
Can a backdated medical certificate be accepted?
In Australia, retrospective certificates are sometimes issued by treating GPs based on clinical history. DoctorsNote does not issue backdated certificates. Whether a backdated certificate is accepted by an employer is at the employer's discretion and subject to workplace policy.
