Annual And Sick Leave Entitlements In Australia: What Employers Need To Know

Running a small business often means wearing a lot of hats. One week you’re focused on sales and growth, and the next you’re dealing with rosters, payroll and leave requests that need immediate answers.

That’s where annual leave and sick leave can get tricky. If you get it wrong (even unintentionally), it can create employee disputes, underpayment risks, Fair Work issues and a lot of admin stress.

The good news is that once you understand the core rules around annual leave and sick leave in Australia, you can build simple systems and policies that keep your business compliant and your team supported.

Below, we break down what small businesses need to know about annual leave and sick leave, the most common “grey areas”, and the practical steps you can take to manage leave confidently.

What Counts As Annual Leave And Sick Leave In Australia?

At a high level, annual leave and sick leave (also called personal/carer’s leave) are different entitlements with different purposes.

Annual Leave (Paid Time Off For Rest And Recreation)

Annual leave is paid time off that eligible employees accrue over time. It’s designed for rest, holidays and general time away from work.

For most employees covered by the National Employment Standards (NES) under the Fair Work Act 2009 (Cth):

• Full-time employees generally accrue 4 weeks of annual leave per year of service.
• Part-time employees generally accrue annual leave on a pro-rata basis (based on their ordinary hours).
• Most casual employees do not accrue annual leave (they usually receive a casual loading instead).

When your team takes annual leave, you generally need to pay it at their base rate of pay for their ordinary hours (plus any relevant loadings/allowances if their award or agreement requires it). If you want a clearer picture of how annual leave pay typically works in practice, annual leave payments is a helpful reference point.

Sick Leave / Personal Carer’s Leave (For Illness Or Caring Responsibilities)

Sick leave is part of “personal/carer’s leave”. It’s paid leave that eligible employees can use when they:

• are unfit for work due to a personal illness or injury; or
• need to provide care or support to an immediate family or household member (for example, if they’re sick or have an unexpected emergency).

For most employees under the NES:

• Full-time employees generally accrue 10 days of paid personal/carer’s leave per year (based on their ordinary hours of work).
• Part-time employees also accrue paid personal/carer’s leave based on their ordinary hours (so the “10 days” reflects an equivalent portion of their usual working year, rather than a simple calendar-day pro-rata).
• Casual employees generally do not receive paid personal/carer’s leave, but may be entitled to unpaid carer’s leave in certain circumstances (and may also have access to unpaid compassionate leave and unpaid family and domestic violence leave under the NES).

Even if you’re across the basic numbers, the real compliance risk usually sits in the “how” questions: how leave accrues, how it’s requested, when evidence is required, and what you can (and can’t) say no to.

How Annual Leave Accrues, Is Taken And Is Paid (From An Employer’s Perspective)

If you employ staff, annual leave isn’t just something that happens when someone goes on holiday. It’s an ongoing entitlement you need to track, approve and pay correctly.

Accrual And Record Keeping

Annual leave generally accrues progressively throughout the year based on ordinary hours worked. This means:

• you should have a reliable payroll system that tracks leave balances accurately; and
• you should keep good employment records, including leave taken and leave balances.

If you have employees covered by a modern award or enterprise agreement, there can be extra requirements around annual leave loading, cashing out leave, or direction to take leave during shutdown periods.

Can You Refuse An Annual Leave Request?

In many workplaces, annual leave is taken by agreement. As a small business owner, you can usually refuse a request if it would be reasonable to do so (for example, critical staffing shortages, peak trading periods, or too many people already on leave). Under the NES, you must not unreasonably refuse an employee’s request to take paid annual leave.

What’s “unreasonable” can depend on the circumstances and on any award or agreement terms that apply to your business. If you want a practical guide to the decision-making framework, refusing annual leave is worth keeping in mind.

Annual Leave During Notice Periods And On Exit

When someone resigns or you terminate their employment, annual leave is often one of the biggest final pay items you’ll need to calculate correctly.

Common scenarios include:

• Employee resigns with accrued annual leave: you generally need to pay out unused annual leave in their final pay.
• Employee takes annual leave during their notice period: this can sometimes happen by agreement, but you should handle it carefully so your records and final pay remain accurate.
• Business wants the employee to finish immediately: you might look at paying out notice instead of having them work it.

It’s usually a good idea to have a consistent approach and to check what your employee’s contract, award and the NES require. For more detail on your obligations at resignation, annual leave on resignation is a useful starting point.

If you end up paying out notice rather than having the employee work through it, you’ll also want to understand the basics of payment in lieu of notice so your offboarding process stays compliant and well documented.

How Sick Leave Works: Evidence, Patterns And Common Grey Areas

Sick leave can be one of the most sensitive topics in a workplace. You want to support your people and keep the business moving, but you also need to manage costs, fairness, and operational continuity.

When Can You Ask For Evidence?

Employees can be required to provide evidence that would satisfy a reasonable person that the leave is genuinely taken for illness/injury or caring responsibilities.

In practice, that evidence might be a medical certificate or a statutory declaration, depending on your workplace policy, any applicable award or enterprise agreement requirements, and the circumstances.

A common question we hear is: “Do employees always need a certificate?” Not necessarily. Some workplaces allow a limited number of sick days without a medical certificate, but you need to make sure your approach lines up with the NES, any applicable award or agreement (which may set specific evidence rules), and your own policies. If you’re weighing up what’s reasonable, sick days without a certificate is a helpful guide to the typical issues small businesses face.

What If You Suspect Misuse?

Sometimes you’ll notice patterns, like frequent sick leave on Mondays or around public holidays. While that can raise concerns, it’s important to handle it carefully.

From a risk-management perspective, it’s usually better to:

• rely on a clear policy that sets expectations around notice and evidence;
• apply the policy consistently across your team;
• keep communications professional and factual (avoid assumptions); and
• document what happens (requests, evidence received, and outcomes).

If the situation escalates into a performance or conduct issue, you’ll want to ensure you follow a fair process and avoid adverse action risks.

Sick Leave During A Notice Period

Another common scenario is an employee taking sick leave during their notice period. This can feel frustrating operationally, especially if you’re trying to hand over work or finalise rosters.

However, sick leave doesn’t automatically stop being available just because someone has resigned or been given notice. The key is to treat the request like you would at any other time: check whether it fits within the entitlement, and whether evidence is required under your policy, the NES, and any applicable award or enterprise agreement.

How Annual Leave And Sick Leave Interact (And What You Can And Can’t Do)

This is where many small businesses get caught out: annual leave and sick leave are separate entitlements, but real-life situations often blur the line.

If An Employee Gets Sick While On Annual Leave

If an employee becomes sick or injured while on annual leave, they may request to have that period treated as personal/carer’s leave instead of annual leave (provided they meet the requirements and have evidence).

That means you might need to:

• re-credit the annual leave for the relevant days; and
• deduct personal/carer’s leave instead (if they have enough accrued).

This is exactly the kind of scenario where a clear leave policy and consistent evidence requirements help you avoid disputes later.

Can You Make An Employee Use Annual Leave Instead Of Sick Leave?

Generally, you shouldn’t force someone to use annual leave when they’re entitled to personal/carer’s leave. Annual leave and sick leave serve different purposes, and mixing them up can create underpayment and compliance risks.

That said, there are related questions that come up in practice, such as whether someone can choose to use annual leave when they’re sick (for example, if they have no personal leave left). This is nuanced and should be handled carefully. If you’re dealing with that scenario, annual leave for sick leave is a useful reference for understanding the general approach under Fair Work.

What Happens When Personal Leave Runs Out?

It’s not uncommon for employees to exhaust their paid sick leave entitlement, especially in workplaces with physically demanding roles, or where someone is managing an ongoing health condition.

When that happens, options might include unpaid leave, annual leave by agreement, or other arrangements depending on the circumstances (and potentially the need to consider discrimination and reasonable adjustments if there’s a medical condition involved).

The best approach is to address this early, keep communication open, and document what’s agreed.

Practical Compliance Steps For Small Businesses (Policies, Rosters And Contracts)

Managing annual leave and sick leave becomes much easier when you build a simple system around it. You don’t need to overcomplicate things, but you do need a consistent, compliant framework.

1. Use A Clear Employment Contract

Your employment contract is often the first place employees look when they’re unsure about leave, notice, and workplace rules. Having the right clauses can reduce confusion and help you enforce consistent processes.

For example, your contract might set expectations around:

• how much notice an employee should give before taking leave (where reasonable);
• when evidence is required for sick leave; and
• how leave requests should be submitted and approved.

If you’re hiring staff (or you’re not confident your current documents are up to date), having an Employment Contract that fits your business and award coverage can make day-to-day leave management far smoother.

2. Create A Leave Policy That Matches How You Actually Operate

A workplace policy helps your team understand what you expect in practical terms. This is especially useful if you manage shift workers, part-time schedules, or a growing team.

A good leave policy usually covers:

• how to request annual leave (lead time, approval steps, blackout periods if needed);
• how to notify you of sick leave (who to contact, by when, and what details are required);
• evidence requirements for personal/carer’s leave; and
• how leave impacts rosters and payroll cut-off times.

To be effective, the policy needs to be applied consistently. If you make exceptions, record why, so you can demonstrate you’re being fair and reasonable.

3. Keep Breaks, Rosters And Leave Working Together

Leave problems often show up alongside rostering problems, particularly in hospitality, retail, health and service-based industries.

For example, issues can arise when:

• a roster is changed at short notice due to unexpected sick leave;
• break entitlements aren’t met because you’re short-staffed; or
• you rely heavily on “informal arrangements” instead of documenting changes.

Even though breaks aren’t the same as leave, they’re part of the same compliance picture (and often part of the same disputes). It can help to keep a practical guide to Fair Work breaks in mind when you’re reviewing how your rosters operate during busy periods.

4. Train Your Managers (Even If It’s Just You)

If you have team leaders or supervisors, make sure they understand your process for:

• approving annual leave;
• responding to sick leave notifications;
• asking for evidence appropriately; and
• escalating issues if there are patterns or concerns.

If it’s just you running the show, a simple checklist can help you respond consistently when you’re under pressure.

5. Watch For Award Or Enterprise Agreement Requirements

The NES is the baseline, but many businesses have extra obligations under a modern award or enterprise agreement. This can affect things like:

• annual leave loading;
• rules about directing employees to take leave (for example, during shutdowns); and
• procedural rules for leave requests and evidence.

If you’re not sure what applies to your team, it’s worth getting clarity early, especially before you scale your headcount.

Key Takeaways

• Annual leave and sick leave are separate entitlements with different purposes, and mixing them up can create compliance risks for your business.
• Annual leave generally accrues progressively (4 weeks per year for full-time employees), and unused annual leave usually needs to be paid out on termination.
• Personal/carer’s leave (sick leave) generally accrues based on an employee’s ordinary hours (often described as 10 days per year for full-time employees), and you can require reasonable evidence in many situations.
• If an employee is sick during annual leave, they may be able to have that time reclassified as sick leave (with evidence), meaning you may need to re-credit annual leave.
• Your best protection is a consistent system: an up-to-date employment contract, a clear leave policy, accurate records, and a fair approach to approvals and evidence.
• Final pay and notice period issues can be high-risk, so it’s worth double-checking annual leave payouts and any payment in lieu of notice arrangements.
