Statutory Declarations for Sick Leave in Australia: A Practical Navigation Guide

Taking time off when you’re unwell is important. But what happens if you can’t get into a GP, or your illness doesn’t require a doctor’s visit? In many Australian workplaces, a statutory declaration can be used to verify sick leave in place of a medical certificate.

In this guide, we’ll unpack when a stat dec is appropriate, what it must include, who can witness it, and how to manage the process fairly as an employer or employee. Our goal is to help you confidently handle sick leave documentation without unnecessary stress or confusion.

If you need a deeper dive into the document itself, we’ve also covered how to write a statutory declaration for sick leave, including practical drafting tips.

What Is a Statutory Declaration for Sick Leave?

A statutory declaration is a formal written statement that you sign to declare something is true. In the context of sick leave, it’s a signed statement from the employee stating they were not fit for work on a specific date (or dates), and explaining why (for example, flu symptoms, gastro, or a family emergency covered by personal/carer’s leave).

It’s a legal document. Making a false declaration is an offence, so it carries weight even though it’s not issued by a medical professional.

A stat dec is commonly used when:

• The illness is short and straightforward (e.g. a 1-2 day bug).
• You couldn’t reasonably obtain a medical certificate (e.g. no appointments available, after-hours illness, or isolation requirements).
• Your employer’s policy allows statutory declarations in certain circumstances (often for absences under a threshold number of days).

For everyday absences, many employers accept a stat dec as reasonable evidence. However, there are limits and it’s not a “one size fits all” replacement for medical certificates.

When Will a Statutory Declaration Be Accepted by Employers?

Under the Fair Work system, an employer can ask for “evidence that would satisfy a reasonable person” that you took personal/carer’s leave because you were unwell or caring for an immediate family or household member. A statutory declaration can meet that standard in many situations.

Whether a stat dec will be accepted often depends on:

• Workplace policy or Enterprise Agreement terms (some specify medical certificates after a set number of days).
• The length of the absence (employers may require a medical certificate for longer absences).
• The pattern of absences (e.g. frequent Mondays may prompt the employer to ask for stricter evidence).
• The role and risks involved (safety-critical roles may require medical clearance to return).

Employers should apply policies consistently and fairly. If you’re setting or updating your sick leave rules, make sure your Employment Contract and Workplace Policy clearly explain what evidence is required and when.

It’s also helpful to understand where the line sits on proof. We’ve explored this in more detail in our guide on when employers can legally ask for medical certificates and how to manage requests proportionately and lawfully.

For employees, if your employer accepts stat decs in some situations, you may not need to visit a doctor for a minor illness. We’ve broken down how to approach sick days without a certificate so you know your rights and obligations.

How to Prepare and Lodge a Statutory Declaration (Step by Step)

If you’re relying on a stat dec for sick leave, getting it right matters. Here’s a practical, step-by-step approach.

1. Check Your Workplace Policy

Confirm when a stat dec is acceptable and what details it must include. Policies will often specify:

• How soon you must notify your manager.
• The maximum number of days you can self-certify with a stat dec.
• Whether consecutive or patterned absences require medical certificates.

2. Use the Right Statutory Declaration Form

Each state and territory has an approved form for statutory declarations. While the content is similar, the witnessing categories and form layout can differ. Use the current version for your jurisdiction to avoid issues down the track.

3. Include the Essential Details

In plain, factual language, state:

• Your full name, address, and role (if relevant).
• The dates you were unwell and unfit for work (or caring responsibilities).
• A brief description (e.g. “gastrointestinal illness and unable to perform duties”).
• That the declaration is true and correct.

Stick to facts. You don’t need to share private medical history-only enough information to satisfy a reasonable person you were legitimately unwell.

4. Arrange a Qualified Witness

Statutory declarations must be witnessed by an authorised person (covered below). Don’t sign the document until you’re in front of the witness-they need to see you sign.

5. Submit the Stat Dec Promptly

Provide it within the timeframe your policy sets (often the next working day or within a few days of returning). Keep a copy for your records. If you are a casual employee or work irregular hours, the same principles apply; we discuss supporting evidence in our guide to medical certificates for casual employees.

6. Return-to-Work Requirements

Some workplaces ask for a short return-to-work discussion or a medical clearance after certain illnesses or long absences, especially in safety-sensitive roles. If you’re unsure, check the policy or ask HR.

Witnessing Requirements Across Australia

Witnessing rules are strict. If your stat dec isn’t properly witnessed, your employer may reject it. Approved witnesses differ by state/territory but often include:

• Justices of the Peace (JP) and commissioners for declarations.
• Legal practitioners, court registrars, or police officers.
• Certain professionals (e.g. pharmacists, teachers, accountants) depending on the jurisdiction.

Key tips to get witnessing right:

• Use the correct jurisdiction form and list of authorised witnesses.
• Bring ID if the witness doesn’t know you personally.
• Sign in front of the witness-never sign in advance.
• Ensure the witness completes their section fully (name, qualification, signature, date).

If your workplace operates across multiple states, adopt a clear policy that recognises validly witnessed declarations made in any Australian jurisdiction, provided the form and witnessing rules are followed.

Managing Sick Leave Fairly: Policies, Privacy and Record-Keeping

For employers, a clear framework helps you support staff while protecting your business. Here’s how to keep things compliant and consistent.

Set Expectations in Writing

Make sure your leave evidence rules are clearly explained in your Employment Contract and supported by a practical Workplace Policy. Explain when a stat dec is appropriate, when a medical certificate is required, notification timeframes, and how evidence should be submitted.

If you don’t already have a broader handbook, consider rolling leave rules into a staff policies pack so your team knows what to do and managers apply it consistently.

Apply the “Reasonable Person” Test

The Fair Work framework focuses on whether the evidence would satisfy a reasonable person. A brief, truthful stat dec will generally meet this test for short, straightforward absences. For longer or repeated absences, it’s reasonable to ask for a medical certificate or other evidence.

If entitlements are running low or exhausted, think about your options early-our guide on managing employee sick leave when entitlements run out walks through alternatives like annual leave, leave without pay, or reasonable adjustments.

Respect Privacy

Personal and health information must be handled sensitively and only shared on a need-to-know basis. You don’t need detailed diagnoses-focus on whether the person was unfit for work for the relevant time.

Keep Accurate Records

Maintain records of leave requests, stat decs, and any certificates or communications. Good records support payroll accuracy and help if a dispute arises.

Avoid Discrimination or Adverse Action

Be careful not to penalise someone for taking leave they’re entitled to. Handle patterns or concerns through your performance and capability processes, not by refusing legitimate evidence or applying policy inconsistently.

Train Managers

Managers are often the first contact when employees call in sick. Provide guidance so they know when to request evidence, how to respond compassionately, and when to escalate.

Key Scenarios and Practical Pitfalls to Avoid

Understanding common scenarios helps you respond confidently and fairly.

1-2 Day Absences for Minor Illness

Many workplaces accept a stat dec for short absences where a GP visit is impractical. Asking every employee to see a doctor for a short cold can add unnecessary cost and pressure on the healthcare system. A stat dec is often reasonable evidence in these cases.

Longer Absences or Recurrent Patterns

For absences beyond your policy’s threshold, or where there’s a pattern (e.g. frequent Mondays), it’s reasonable to ask for a medical certificate. Make sure your requests are proportionate and non-discriminatory, and that you apply the rule consistently across the team.

Carer’s Leave

Stat decs can also support carer’s leave where you’re caring for an immediate family or household member. The declaration should state who you cared for, your relationship, the dates, and why your presence was required.

During Notice Periods

Employees remain entitled to personal/carer’s leave during notice periods. Evidence rules still apply, so a stat dec may be acceptable depending on your policy. We’ve covered how to balance rights and compliance in cases of sick leave during an employee’s notice period.

Casual Employees

Casuals don’t accrue paid personal leave, but they may still need to notify the employer and provide reasonable evidence if they can’t attend a shift because they’re unwell. Your policy should make the expectations clear (for example, when a stat dec or certificate is needed for missed shifts). See also our employer-focused guide on medical certificates for casual employees.

When Stat Decs Shouldn’t Be Used

There are situations where a stat dec isn’t appropriate, such as:

• Return-to-work medical clearance after a serious injury or illness.
• Safety-critical roles where fitness must be assessed by a clinician.
• Extended absences where a practitioner’s input is needed (treatment plan, capacity notes).

In these cases, a medical certificate or report is a better fit.

Frequent Use Without Support

If someone is frequently unwell, repeatedly relying on stat decs may be a sign to ask what support they need. Consider a supportive conversation, reasonable adjustments, or further evidence if appropriate. Your approach should be consistent with your broader obligations to manage health and safety at work.

Evidence After Entitlements Run Out

If paid personal leave is exhausted, the employee may still take unpaid leave if unfit for work, with reasonable evidence. Review available alternatives and communicate clearly, drawing on the steps outlined in our guide to managing sick leave when entitlements run out.

Clear, Simple Alternatives

In some workplaces, policies allow a set number of “self-certified” days per year using a stat dec. This approach can reduce admin while still giving managers visibility and control. It works best when combined with clear triggers for medical certificates thereafter and a consistent approach to patterns of absence.

Practical Tip for Employees

Tell your manager as early as possible if you’re unwell, follow the policy on who to notify and when, and provide your stat dec or certificate on time. If you’re unsure whether a stat dec is acceptable for your situation, ask your manager or HR before you submit it.

Practical Tip for Employers

Make your expectations crystal clear and stick to them. If you allow stat decs for certain absences, say so. If you require medical certificates after a set threshold, say that too. Align your employment documents-your Employment Contract and Workplace Policy-so staff and managers are on the same page from day one.

Key Takeaways

• A statutory declaration is a legally binding statement that can provide “reasonable” evidence for sick or carer’s leave in many day-to-day situations.
• Whether a stat dec is acceptable depends on your workplace policy, the length and pattern of absence, and the nature of the role-longer or safety-sensitive cases often require a medical certificate.
• To prepare a valid stat dec, use the correct state/territory form, include clear facts (dates and reason you were unfit for work), and sign in front of an authorised witness.
• Employers should set clear rules in the Employment Contract and Workplace Policy, apply them consistently, respect privacy, and keep accurate records.
• Stat decs are useful for short, straightforward absences, but not for situations needing medical clearance or extended capacity assessments.
• Both employees and employers benefit from timely communication-notify early, provide evidence promptly, and talk through any recurring issues with a supportive, consistent approach.
