How To Handle Fake Medical Certificates From Employees In Australia

As a small business owner, you’re likely used to juggling a lot at once: customers, cash flow, rostering, and building a reliable team. So when you suspect an employee has provided a medical certificate that isn’t genuine, it can feel like the ground shifts under you.

On the one hand, you need to protect your business from misconduct, dishonest leave claims, and operational disruption. On the other hand, you must handle the situation carefully, because the legal risks can be serious if you jump to conclusions or take disciplinary action without a fair process.

This guide walks you through what a fake medical certificate issue usually looks like in practice, what your obligations are as an employer in Australia, and a practical step-by-step approach to manage it calmly and legally.

What Counts As A Fake Medical Certificate (And Why It Matters)?

In most workplaces, a medical certificate is provided as evidence that an employee is unfit for work (usually for personal/carer’s leave) or requires work restrictions. When the evidence is genuine, it helps you comply with your obligations while managing attendance fairly.

A fake medical certificate can take a few different forms. For example, you may be dealing with:

• A forged certificate (e.g. altered dates, altered provider details, or a fabricated document)
• A certificate issued by someone who isn’t a registered health practitioner (or that uses false provider details)
• A genuine certificate used dishonestly (e.g. it’s real, but the employee misrepresented the circumstances to obtain it)
• A suspicious “template” certificate that appears copied, generic, or inconsistent with normal provider formatting

Why does this matter? Because if an employee provides false evidence to access paid leave (or to excuse misconduct), it can be a form of serious misconduct and a breach of trust. For many roles, trust is essential, particularly in small teams where absences create immediate pressure.

At the same time, not every “odd-looking” certificate is fake. Some clinics use different templates, some telehealth providers issue short-form certificates, and some employees simply provide incomplete documentation. The key is to respond based on evidence, not assumptions.

What Are Your Legal Risks As An Employer If You Get It Wrong?

When you suspect a fake medical certificate, it’s tempting to move straight to discipline or dismissal. But employers can run into trouble when they:

• accuse an employee without a reasonable basis
• fail to give the employee a chance to respond
• discipline inconsistently compared to past practice (or compared to how similar issues are usually handled)
• collect or disclose medical information improperly
• ignore the possibility of a real illness, disability, or other protected attribute

Depending on what happens, the employee could raise issues such as unfair dismissal, general protections claims, discrimination complaints, or privacy complaints. Even if you ultimately have strong evidence, poor process can make a defensible situation much harder to manage.

Evidence, Privacy And “Medical Information”

Medical information is sensitive. Even when you have a legitimate reason to check a certificate, you should keep your enquiries narrow and professional, and comply with any workplace privacy obligations and policies. For example, you are generally trying to confirm:

• Was the certificate issued by that provider (or practice)?
• Does it relate to the employee?
• Does it cover the dates claimed?

Avoid turning this into a broad fishing expedition about diagnosis or private health details.

Also, if you’re considering work restrictions or a return-to-work process, it can be helpful to understand when you can ask for medical clearance, especially where safety is involved.

How Should You Respond To A Suspected Fake Medical Certificate? (Step-By-Step)

If you think an employee has submitted a fake medical certificate, your goal is to respond in a way that is fair, well-documented, and consistent with your contracts, policies, and any applicable Award or enterprise agreement.

Below is a practical process many employers follow.

1) Pause And Gather What You Already Have

Start by collecting the documents and facts you already have, such as:

• the medical certificate (save a copy)
• the employee’s leave request (email, app screenshot, text message)
• the rostered shifts and any timesheets
• any relevant workplace policy on leave evidence and misconduct
• notes about why you suspect it may be fake (objective reasons only)

It’s important that you record facts (what happened, what the document shows, what inconsistencies exist) rather than conclusions (“it’s obviously fake”). This becomes crucial if the matter escalates.

2) Check Your Employment Contract And Workplace Policies

Before contacting the employee, check what your documents say about evidence requirements and misconduct processes. If your Employment Contract and policies clearly outline what evidence is required and what happens if false information is provided, you’ll be in a stronger position to manage the issue consistently.

Also check any applicable modern Award or enterprise agreement, as these can include specific rules about when evidence is required and what counts as acceptable evidence.

If your documents are silent or unclear, you can still investigate, but you’ll want to be extra careful about fairness and consistency.

3) Consider Whether You Need To Stand The Employee Down (Only If Justified)

Not every suspected fake medical certificate requires standing the employee down. In many cases, you can investigate while the employee continues working.

However, in some situations you might consider a stand down pending investigation (for example, if there is a serious integrity issue, safety risks, or concerns about interference with evidence). This is a step that should be handled carefully and usually with advice, because your ability to stand an employee down (and whether it’s paid or unpaid) depends on the legal basis for doing so. This can be affected by the Fair Work Act, the employee’s contract, and any applicable Award or enterprise agreement.

If you’re looking at this option, it helps to understand the principles behind standing down an employee pending investigation.

4) Ask The Employee For An Explanation (Procedural Fairness)

Next, raise the issue with the employee privately and calmly. The purpose of this conversation is not to “win” or to accuse them on the spot. It’s to give them a genuine opportunity to explain.

In practice, this often means:

• setting a meeting time (in person or via video call)
• telling them the issue you’re investigating (e.g. inconsistencies with the certificate)
• giving them a chance to respond and provide further evidence
• keeping a written record of the discussion

Sometimes there is a reasonable explanation (wrong dates entered by the practice, a clinic reissued the certificate, the employee uploaded the wrong file, or the provider uses a telehealth system that looks unfamiliar). You want your process to be strong enough that you can make a confident decision either way.

5) Verify The Certificate Carefully (Without Overstepping)

If the concerns remain, you may decide to verify the certificate. A common approach is to contact the provider’s clinic and ask whether they issued a certificate with the listed reference details. In practice, some clinics won’t confirm anything without the employee’s consent (and you should avoid pressuring a clinic to disclose private information).

A few practical tips:

• Keep questions minimal: focus on confirming authenticity, not diagnosis.
• Use a neutral tone: you’re verifying a document, not alleging wrongdoing to the clinic.
• Keep records: note who you spoke to, when, and what they confirmed (or declined to confirm).

If the certificate is confirmed as not genuine, you’re moving into a misconduct process.

6) Put Allegations In Writing (Often Via A Show Cause Process)

If the evidence supports that the employee provided a fake medical certificate, you should usually put the key allegations in writing and invite a response before deciding on disciplinary action.

Many employers do this through a “show cause” letter, which sets out:

• what the alleged conduct is
• the evidence relied on (at a high level)
• why it is considered serious (e.g. dishonesty, breach of policy)
• the possible consequences (including termination, if applicable)
• a deadline for the employee’s response

If you haven’t used one before, it can help to understand how show cause letters are commonly handled in Australian workplaces.

7) Decide On The Right Outcome (Discipline, Repayment, Or Termination)

Once you have the employee’s response (or they don’t respond by the deadline), you can decide what action is appropriate. The right response depends on factors like:

• how clear the evidence is
• whether this was deliberate
• whether the employee has prior warnings or a clean record
• the seniority of the role (some roles require higher trust)
• the impact on your business

Potential outcomes may include:

• No further action (if the concerns were not substantiated)
• A formal warning (if there’s misconduct but not at a termination level)
• Repayment discussions (if paid leave was accessed dishonestly - but get advice before making any deduction from wages, as deductions generally need to be authorised and lawful)
• Termination (where the conduct is serious and the process has been fair)

Termination is usually the highest-risk option legally, so you want to ensure the reason and process are well supported. If the employee is still within probation, different risks may apply, but process still matters. It can be useful to keep in mind the considerations around termination during probation.

8) Document Everything

Even if the situation resolves quickly, keep a clear file including:

• the certificate and any versions provided
• notes of meetings and phone calls
• written correspondence
• your decision-making reasons

This helps you stay consistent, reduces the risk of misunderstandings, and protects you if the employee later challenges the outcome.

How Can You Prevent Fake Medical Certificate Issues In The First Place?

Prevention is always easier than investigation. While you can’t fully eliminate the risk of a fake medical certificate, you can make your expectations clear and reduce grey areas.

Have Clear Rules On Leave Evidence

Put your expectations in writing in your employment contracts and policies. This often includes:

• when evidence is required (e.g. after 2+ consecutive days, or where required under an Award/enterprise agreement)
• what types of evidence you accept
• timeframes for providing evidence
• what happens if evidence is not provided or is false

It’s also worth thinking through how you handle “no certificate” situations. In some workplaces, employees may be allowed to take limited sick leave without evidence, depending on your policies and the applicable Award/enterprise agreement. If this comes up often, you may want to review your approach to sick days without a certificate so your expectations are consistent and defensible.

Consider Alternative Evidence Pathways (Like Statutory Declarations)

In some situations, an employee may genuinely be unable to obtain a certificate (for example, limited appointment availability). Depending on the circumstances and your workplace rules (and any applicable Award/enterprise agreement), a statutory declaration may be an option.

If you plan to accept stat decs in some cases, it helps to ensure staff understand what they are and how they’re completed properly. Many businesses keep guidance on statutory declarations for sick leave to reduce confusion.

Train Your Managers On Consistency And Confidentiality

Small businesses often rely on team leaders to approve leave and handle day-to-day issues. If those leaders:

• apply rules inconsistently, or
• gossip about an employee’s health, or
• accuse employees informally without evidence

it can quickly escalate into conflict and legal risk.

A simple process (documented, consistent, respectful) goes a long way.

Common Questions From Employers About Fake Medical Certificates

Can I Refuse To Pay Personal Leave If I Think The Medical Certificate Is Fake?

If you have a reasonable basis to suspect the evidence is not genuine, it’s usually safer to treat it as an investigation issue rather than immediately refusing payment. Often, the next step is to request clarification or further evidence and then decide whether the leave request should be approved once you’ve assessed the information, having regard to the Fair Work Act and any applicable Award/enterprise agreement.

Because wage and entitlement issues can escalate quickly (including underpayment risk), get advice before withholding entitlements or making deductions, especially if the employee disputes your concerns.

Should I Report A Fake Medical Certificate To The Police?

Forging documents can be a criminal matter. Whether to report it can depend on the seriousness, evidence, business impact, and what outcome you’re trying to achieve.

In many employment situations, the priority is managing the employment relationship lawfully (investigation, discipline, termination where justified). Reporting to police can also add complexity, so it’s worth getting legal advice before taking that step.

What If The Employee Has A Genuine Health Issue But Lied About The Certificate?

This can happen. For example, an employee might be unwell, but panic about not having evidence, or might be dealing with an underlying condition.

Even if there is a real health issue, providing a fake medical certificate can still be serious misconduct. However, you should be careful to consider whether there are health or capacity issues you need to manage separately (including any duties to consider reasonable adjustments).

If the situation is evolving into a capacity/medical fitness issue rather than pure misconduct, you may also want to understand your obligations around termination on medical grounds, as the legal considerations are different.

What If I’m Not 100% Sure It’s Fake?

If you can’t substantiate it, avoid disciplinary action based purely on suspicion. Instead, focus on:

• requesting clarification or additional evidence
• clarifying expectations going forward
• updating policies and processes to reduce future uncertainty

Where the evidence is unclear, a measured response is usually the most legally defensible approach.

Key Takeaways

• A fake medical certificate can involve forgery, altered details, or dishonest use of medical evidence, and it can be treated as serious misconduct in many workplaces.
• Even if your suspicions are strong, you should investigate carefully and give the employee a genuine opportunity to respond before deciding on discipline or termination.
• Verification should be narrow and professional, focusing on confirming authenticity rather than seeking private medical details.
• A written process (often including a show cause letter) and clear documentation can significantly reduce legal risk if the employee challenges the outcome.
• Strong contracts and workplace policies help prevent disputes by setting clear expectations around leave evidence and misconduct from day one.
