Annual Leave vs Sick Leave in Australia: Key Points for Employers

Leave entitlements are central to a fair, compliant workplace - but it’s easy to mix up what counts as annual leave and what’s personal/carer’s (sick) leave under the National Employment Standards (NES).

If you’re an employer in Australia, understanding the differences - who’s entitled, how leave accrues, when evidence can be requested, and what happens on termination - will help you approve requests confidently, prevent disputes and stay compliant with Fair Work obligations.

Below, we break down the essentials in plain English, spotlight common pitfalls, and share practical steps to manage leave consistently across your team.

What’s The Difference Between Annual Leave And Sick Leave?

Annual leave and personal/carer’s (sick) leave serve different purposes and are treated differently under the NES.

Annual leave (paid)

• Purpose: Rest and recreation. Employees typically plan this in advance.
• Who gets it: Permanent full-time and part-time employees.
• Accrual: Generally four weeks per year of service (pro‑rata for part‑time), with additional weeks in some cases for shiftworkers.
• When it’s taken: By agreement with the employer, taking into account business needs and any award or enterprise agreement rules.
• Payment: Paid at the employee’s base rate for ordinary hours. In some industries or under certain awards, annual leave loading may apply.
• Cash out: Permitted only if strict conditions are met (more on this below).

Personal/carer’s leave (sick leave)

• Purpose: Time off when the employee is unwell or injured (personal leave), or to provide care or support to an immediate family or household member due to illness, injury or an unexpected emergency (carer’s leave).
• Who gets it: Permanent full-time and part-time employees (paid). Casual employees do not receive paid sick leave but can access certain unpaid leave entitlements.
• Accrual: Generally 10 days per year of service for full-time employees (pro‑rata for part‑time), accruing progressively.
• When it’s taken: As needed, with notice as soon as practicable. Evidence requirements apply.
• Payment: Paid at the employee’s base rate for ordinary hours if the employee has accrued paid leave available.

Key difference in practice: Annual leave is usually scheduled and discretionary (subject to business needs), whereas sick leave is reactive to illness or caring responsibilities and is protected when genuine and supported by appropriate evidence.

Who Is Entitled And How Does Leave Accrue?

Leave entitlements depend on employment status and are shaped by the NES plus any applicable modern award or enterprise agreement.

Full-time and part-time employees

• Annual leave: Accrues progressively based on ordinary hours and carries over year to year if unused.
• Personal/carer’s leave: Also accrues progressively and carries over if unused.
• Public holidays: If a public holiday falls during a period of annual leave, the day is treated as a public holiday, not a day of annual leave.

Casual employees

• No paid annual leave or paid personal/carer’s leave entitlements.
• May access unpaid carer’s leave and compassionate leave, and other NES entitlements that apply to casuals.

Accrual mechanics and record-keeping

• Accrual should be calculated and recorded each pay period.
• Keep accurate records of balances, approvals and evidence received - this is a core employer obligation and reduces disputes.
• Use consistent processes for requesting leave, approving or rejecting requests, and storing evidence.

If your business has an enterprise agreement or you operate under an award, always check any additional rules about accrual, taking leave and evidence, as these instruments can set stricter or clearer requirements than the minimum NES.

Approvals, Evidence And Common Scenarios Employers Ask About

Most leave questions arise at the point of approval or when circumstances change unexpectedly. Here are common scenarios to get right.

Can you refuse annual leave?

Yes - you can refuse an annual leave request if it’s not reasonable on business grounds. Think about operational needs, how many others are away, and whether it would unduly impact your customers or safety.

Balance is key: you’re entitled to run your business effectively, but decisions should be fair and consistent. If in doubt, review the principles in refuse annual leave and any award rules before deciding.

What evidence can you ask for with sick leave?

You can require reasonable evidence that would satisfy a reasonable person that the employee was unfit for work (personal leave) or needed to provide care/support (carer’s leave). Commonly, that’s a medical certificate or statutory declaration.

Set expectations in your policies about when evidence is required (for example, any absence, absences of two days or more, or repeated patterns). For guidance, see when employers can ask for medical certificates.

Employees sometimes ask if they can take a sick day without a certificate. The answer depends on your policy, the award/EA and the circumstances. Having a clear, consistently applied rule is your best protection.

Can employees get sick on annual leave?

Yes. If an employee becomes ill or injured during a period of approved annual leave and provides the required evidence, those days are usually reclassified as personal/carer’s leave rather than annual leave. This ensures employees don’t “lose” annual leave to genuine illness.

Can you direct an employee to take annual leave?

In certain circumstances, yes. For example, where an employee has an excessive annual leave balance under an applicable award or EA, or during a shutdown period following the relevant rules. Always check your award/EA clauses first and give reasonable notice.

Can employees take sick leave during the notice period?

If an employee is genuinely unwell during their notice period and has accrued personal leave, they can access it like normal. This can affect their last day, depending on the circumstances and award/EA. For nuance and examples, see sick leave during the notice period.

What if sick leave runs out?

When paid personal/carer’s leave is exhausted, employees may access other options (e.g. unpaid carer’s leave, annual leave by agreement, or unpaid leave). Your policy should outline the pathway and any evidence expectations to support ongoing absence.

Pay, Cashing Out And What Happens On Termination

Getting pay right is critical. These are the rules that most often trip up businesses.

How is annual leave paid?

Annual leave is paid at the employee’s base rate for ordinary hours (check your award/EA for any variations). Some employees may also be entitled to annual leave loading, typically 17.5% or an amount specified in the applicable instrument.

There are also nuances around leave taken during shutdowns, over public holidays or while on other forms of leave. A good primer on calculations is covered in annual leave payments.

Can annual leave be cashed out?

Yes, but only if strict conditions are met - and never below the employee’s minimum entitlements. Typically, cashing out requires a written agreement, a minimum remaining balance and compliance with any award/EA rules. If any condition isn’t met, don’t proceed. Read more about cashing out annual leave before making a decision.

Is sick leave paid out when employment ends?

No. Accrued but unused personal/carer’s (sick) leave is not paid out on termination under the NES or most awards/EAs. This is one of the clearest differences between the two entitlements.

Is annual leave paid out when employment ends?

Yes. Accrued and unused annual leave must be paid out on termination, generally at the employee’s base rate, plus any applicable loading under the award/EA. Double-check timing requirements and payslip details - mistakes here are common and expensive.

For employer obligations at the end of employment, see annual leave payout rules in annual leave on resignation.

Build Strong Processes: Policies, Contracts And Fair Work Compliance

The easiest way to minimise leave disputes is to set expectations clearly from day one and follow the same process every time.

Put your rules in writing

• Leave policy: Outline how to request annual leave, when evidence is required for sick leave, shut-down periods, how excessive balances are managed, and any award/EA specifics that apply to your workforce.
• Consistency: Apply the same rules to everyone unless there’s a genuine, documented reason to depart (for example, reasonable adjustments for illness or disability).
• Training: Make sure managers understand when they can approve or reject leave, what evidence to request, and how to escalate grey areas.

Use fit‑for‑purpose contracts and HR documents

• Employment agreements: Get terms right for permanent staff and casuals (hours, classifications, leave and evidence requirements aligned to the award/EA, notice, termination, and dispute resolution). Clear, well-drafted terms reduce risk when leave questions arise.
• Workplace policies: A staff handbook or suite of policies can cover leave, payroll cut-offs, manager delegation, and return-to-work processes.
• Record-keeping: Use your HRIS or payroll system to collect requests, decisions, and evidence so you can demonstrate compliance if challenged.

Evidence and privacy

When collecting medical certificates or sensitive information, only ask for what you need to verify entitlement and keep it confidential. Limit access to managers and HR, and store documents securely in line with your privacy obligations.

Mental health and safe return to work

If an employee has been unwell for a period, focus on a safe and sustainable return to work. In some cases, you can request fitness-for-duty information to understand any reasonable adjustments you should make. Be mindful of your obligations around discrimination and workplace health and safety.

Communication tips that prevent conflict

• Be transparent: If you need to decline or reschedule annual leave, explain the business reasons and offer alternatives where possible.
• Be prompt: Respond quickly to leave requests and evidence. Delays create uncertainty and erode trust.
• Be fair: Apply your rules consistently, and document decisions - especially when you deviate from policy to accommodate individual circumstances.

Frequently Asked Employer Questions

Can I require a medical certificate for every sick day?

You can require reasonable evidence, but many employers set a minimum threshold (e.g., two days or a pattern of Fridays/Mondays) to balance trust and compliance. Your award/EA may also include specific evidence clauses. It’s sensible to align your policy to the principles covered in requesting medical certificates.

What if an employee can’t produce evidence for a sick day?

Consider whether a statutory declaration is appropriate and whether your policy allows it. If there’s no evidence and concerns about misuse persist, manage the issue through your performance or conduct process - not by retrospectively converting the absence to annual leave without agreement.

Do I have to approve every annual leave request?

No. Approval is subject to operational needs and any award/EA limits. Just make sure your reasoning is sound, consistent, and documented, and consider the guidance in refuse annual leave before you decide.

How should I handle excessive annual leave balances?

Follow your award/EA’s “excessive leave” clauses, which typically allow for consultation and, in some cases, directing leave with proper notice. Proactively encouraging staff to book leave through the year also helps avoid a build-up.

Does sick leave affect annual leave payout when someone resigns?

No. Sick leave is not paid out at termination; annual leave is. Make sure your final pay correctly includes all accrued annual leave (plus any applicable loading), in line with the principles explained in annual leave payments and annual leave on resignation.

Key Takeaways

• Annual leave is paid (often with annual leave loading where applicable) and must be paid out on termination; sick leave is not paid out when employment ends.
• You can refuse annual leave on reasonable business grounds and request evidence for sick leave, but you must apply rules fairly and consistently.
• Cashing out annual leave is allowed only under strict conditions, so check award/EA rules and document agreements properly before proceeding.
• Clear policies, accurate records and strong employment contracts help you manage leave lawfully and reduce disputes.
• Tricky scenarios - like sick leave during the notice period or evidence thresholds - benefit from early legal guidance.
