Sick days are a crucial part of working life in Australia. Whether you’re running a small business or working as an employee, illness is inevitable – and taking time to recover isn’t just a personal need, but a workplace right. Yet, questions often arise around medical certificates, how many sick days can be taken without a doctor’s note, and what the law actually requires. If you’ve wondered “How many sick days can you take without a certificate?” or felt uncertain about calling in sick, you’re not alone.
This guide is designed to answer the common concerns about sick leave without a certificate in Australia, cut through the confusion, and give you the knowledge you need to manage personal leave lawfully and confidently. We’ll explain when you do – and don’t – need a medical certificate, what your rights and obligations are, and how small business owners can stay compliant while supporting their team. Let’s clarify the rules so you can focus on supporting your health and your business the right way.
What Is Sick Leave and When Can You Take It?
Sick leave (or “personal/carer’s leave”) is a paid entitlement available to most employees in Australia. It covers times when you are unwell or injured and unable to work. It also covers caring for an immediate family or household member who is sick, injured, or dealing with an emergency.
Under the National Employment Standards (NES), full-time employees receive at least 10 days of paid personal/carer’s leave each year, and part-time staff get a pro rata amount. This entitlement accumulates from year to year if unused.
Casual employees do not receive paid sick leave, but they do have the right to unpaid carer’s leave in certain situations.
The right to take leave when needed is protected by law. However, there are rules around notice and evidence – especially when it comes to sick days taken without a certificate or doctor’s note.
How Many Sick Days Can You Take Without a Certificate?
One of the most common questions we hear from both business owners and employees is: “How many sick days can I take without a medical certificate?” The short answer is: the Fair Work Act 2009 (Cth) and most modern awards or enterprise agreements in Australia do not set a fixed number of days you can take before you’re required to provide a doctor’s note.
Instead, the law focuses on reasonable employer requests for evidence and the principle of acting “reasonably.”
What Does “Reasonable Evidence” Mean?
Under the NES, if you take paid sick or carer’s leave, your employer is entitled to ask for evidence that you were genuinely entitled to the leave. This evidence can be a medical certificate or a statutory declaration. The Fair Work Ombudsman states that evidence must “satisfy a reasonable person” that you were unfit for work or needed to care for someone.
Importantly, your employer may request evidence for any sick day – even if it’s just one day off. However, in practice, many workplaces adopt an informal rule of only requiring a certificate after two or more days off, or if there is a pattern of frequent short absences. But this is a custom, not a legal requirement.
Common Scenarios
- One Day Off: Legally, your employer can request evidence (such as a medical certificate or statutory declaration) even for a single day’s absence. Not all employers always do so – but it’s within their rights.
- Multiple Days Off: If you are away for more than one day, most employers will expect a medical certificate or statutory declaration to back up your absence.
- No Certificate Policy: Some workplaces permit a set number of “self-certified” sick days – meaning you can call in sick for a certain number of days per year without documentation. However, this is not a legal mandate; it’s an optional workplace policy.
For more on these rules, see our in-depth guide to sick certificates in Australia.
Is a Medical Certificate Required for One Day Sick Leave?
This is a key concern for many employees. While many people assume a certificate is only needed for absences longer than one or two days, the law gives employers the right to request evidence for any period of absence. This means you could be asked for a certificate or statutory declaration after just one sick day.
Most employers exercise this discretion sensibly and do not routinely request a certificate for every sick day (given the costs and inconvenience). However, if an employee takes sick days frequently, particularly around weekends or public holidays, or if there’s a pattern of absences, the employer may reasonably require proof – even for single-day absences.
Best Practice
- Employees: If unsure, always check your company’s policies or speak to your manager about what evidence is required for sick leave.
- Employers: Be clear about your expectations and policy around sick leave evidence in your staff handbook or workplace policy. Consistency and fairness in enforcement are key to morale and compliance with Fair Work laws.
What Counts as Acceptable Evidence for Sick Leave?
Generally, the two most usual forms of evidence for sick or carer’s leave are:
- Medical certificate: A note from a registered health practitioner confirming you were unfit for work.
- Statutory declaration: A legal statement you make affirming your inability to work due to illness or injury or the need to care for someone.
Employers should accept either unless the employment contract, award, or agreement states otherwise. Employers cannot insist that you must see a specific doctor or use a particular form unless stipulated in the contract or award.

What Happens If You Take Sick Leave Without a Certificate?
If you take sick leave without a certificate and your employer does not request evidence, you should still be paid for your entitled personal leave. However, if your employer requests evidence and you’re unable to provide it, they may be able to legitimately withhold payment for the days in question. Furthermore, repeated unexplained absence without proper evidence can lead to formal warnings or, in serious cases, disciplinary action.
On the flipside, unreasonable demands for certificates for every minor absence – without cause – could be challenged, especially if applied inconsistently or in a way that unfairly targets individuals. For more on workplace rights, see our adverse action guide for employers and employees.
Do You Always Need a Medical Certificate for Sick Leave?
No, not necessarily. While a medical certificate is the most common and accepted form of proof for sick leave, a statutory declaration is equally valid under Australian law – unless your employment contract, award, or policy says otherwise. If you can produce either form of evidence on request, you’re complying with the law.
Remember, your notice to the employer should be given “as soon as practicable” (ideally before your shift starts), and you should state how long you expect to be off work. This supports both your legal entitlement and smooth business operations.
How Should Employers Approach Sick Leave Without Certificates?
As an employer, handling employee sick days can feel like a balancing act between supporting your staff and maintaining your business. Setting clear, fair policies – usually in your Workplace Policy or Staff Handbook – about evidence for sick leave will help prevent misunderstandings or disputes.
- Specify when evidence is required – such as after two consecutive days off or after frequent absences.
- Clearly state what forms of evidence are accepted (medical certificate or statutory declaration).
- Make these policies accessible and ensure managers are trained to apply them fairly and consistently.
- Respect privacy – never ask for sensitive medical details beyond confirming incapacity for work.
- If refusing sick leave payment due to lack of evidence, explain your reasons and allow reasonable time for the employee to provide proof.
Taking a reasonable and empathetic approach helps maintain legal compliance and build trust with your team.
What If There’s a Dispute Over Sick Leave or Medical Certificates?
If an employee feels unfairly treated for taking sick leave without a certificate – perhaps where an employer has withheld pay or taken disciplinary action without good reason – they may be able to raise the issue with Fair Work or lodge a complaint internally. In serious, unresolved cases, the Fair Work Commission can hear disputes over personal leave rights or adverse action.
Employers should have a clear complaints procedure or grievance policy to handle these situations.
Employees should keep their own records of communication, certificates, and any requests made in writing.
Are There Any Changes to Sick Leave Laws to Know About?
Australian workplace laws are frequently updated. While the basic entitlements around sick leave and certificates have remained stable for years, it’s a good idea to stay up to date – especially as new Modern Award changes can alter processes for specific industries.
Sprintlaw regularly covers employment law updates, including amendments to Fair Work legislation and casual worker law changes. If you’re not sure where you stand, it’s sensible to check with a legal expert.
What Legal Documents Should Employers Have in Place?
Strong documentation not only clarifies everyone’s rights and responsibilities, but also helps manage risk. These documents support best practice around personal and sick leave:
- Employment Agreements: Clearly outline personal leave entitlement, evidence requirements, and expectations – this is essential protection for both staff and employer. Learn more about employment contract essentials here.
- Workplace Policy or Staff Handbook: Set out practical rules about how to apply for leave, what evidence is required, and how you’ll handle absence disputes. Review and update regularly.
- Disciplinary Policy: Details the steps that will be taken if leave is abused or evidence is repeatedly not provided when required.
- Privacy Policy: Outlines how sensitive medical information will be handled (especially if storing or discussing medical certificates).
