Casual Sick Leave Entitlements in NSW: Employer’s Guide

Running a business in New South Wales often means relying on casual employees to cover peaks in demand and changing rosters. Managing absences is part of that picture - and getting casual sick leave right is critical for compliance, fairness and smooth operations.

If you’ve ever wondered what casuals are actually entitled to when they’re unwell, whether you can ask for a medical certificate, or how to handle last‑minute cancellations, you’re not alone.

In this guide, we’ll clarify what “sick leave” looks like for casuals under the National Employment Standards (NES), when evidence is reasonable, and the practical steps to manage requests lawfully in NSW.

What Counts As “Sick Leave” For Casuals In NSW?

Under the NES (which apply nationally, including NSW), casual employees do not accrue or receive paid personal/carer’s leave. That paid entitlement applies only to permanent (full‑time and part‑time) staff.

Casuals also don’t have a standalone entitlement to unpaid leave for their own illness or injury. If a casual is unwell, they can decline a shift - there’s simply no payment for time not worked.

However, casuals do have other important leave protections:

• Unpaid carer’s leave: Up to 2 days of unpaid carer’s leave per permissible occasion to care for or support an immediate family or household member who is ill, injured or affected by an unexpected emergency.
• Unpaid compassionate leave: 2 days of unpaid compassionate leave per permissible occasion (for example, the death or life‑threatening illness of an immediate family or household member).
• Paid family and domestic violence (FDV) leave: 10 days of paid FDV leave per year for all employees (including casuals), available upfront and paid at the full rate for the hours the casual would have worked had they not taken the leave.

These entitlements sit alongside your general duty not to take adverse action against an employee who is temporarily unfit for work due to illness or who exercises a workplace right. For a broader view of how the NES treats different employment types in NSW, see sick leave entitlements in NSW.

Do Casual Employees Need To Provide A Medical Certificate?

It depends on the entitlement being accessed and any applicable modern award, enterprise agreement or workplace policy.

For casuals, you can typically request reasonable evidence where they access:

• Unpaid carer’s leave: Evidence that would satisfy a reasonable person that the leave is genuinely required (for example, a medical certificate for the family member or a statutory declaration).
• Compassionate leave: Evidence of the permissible occasion (for example, a funeral notice or letter from a medical practitioner).
• FDV leave: Evidence may be required if it’s reasonable in the circumstances (the law sets out broad examples, and employers must handle any information confidentially).

Because casuals don’t have a personal sick leave entitlement for their own illness, there’s no “evidence for unpaid sick leave” to approve. That said, your policies can require timely notification of an absence and may outline when you’ll ask for supporting information, particularly if you need to manage rostering, repeated short‑notice cancellations or work health and safety risks.

It’s best practice to set this out clearly in a policy and apply it consistently. For practical parameters and common scenarios, see our guide on medical certificates for casual employees.

How To Handle Casual Absences Step By Step

A clear, repeatable process reduces stress for both managers and staff. Here’s a simple framework you can adopt.

1) Ask For Timely Notice

Require casuals to notify you as soon as possible if they’re unable to work a rostered shift. Specify who to contact and the method (call, SMS or email). Written notice is helpful for record‑keeping.

2) Identify The Right Entitlement

Clarify whether the absence relates to the casual’s own illness (no paid or unpaid sick leave), unpaid carer’s leave, compassionate leave or FDV leave. The entitlement informs whether the absence is approved, whether it’s paid, and what evidence may be reasonable.

3) Request Evidence When It’s Reasonable

If the casual is seeking unpaid carer’s leave, compassionate leave or FDV leave, request evidence that would satisfy a reasonable person, aligned with any award or agreement. Make sure your policy explains what’s acceptable (for example, a medical certificate or statutory declaration).

4) Confirm The Outcome And Pay Status

Let the employee know if the absence is approved and whether it’s paid (FDV leave) or unpaid (carer’s or compassionate leave). If it’s the casual’s own illness and they’re not accessing a leave entitlement, the shift is not worked and not paid.

5) Keep Accurate Records

Record the notification, entitlement type, evidence provided (without unnecessary sensitive detail), approval decision and any pay adjustments. Good records help you demonstrate compliance.

6) Consider WHS And Return To Work

Where there are safety concerns about an employee’s fitness for work or a risk of harm to themselves or others, it may be reasonable to request a medical clearance before they return. The threshold is contextual - review your duties and process carefully, and see medical clearance to return to work for guidance.

7) Apply Policies Consistently

Consistency is key. Inconsistent treatment can create compliance issues and undermine culture. If a unique situation arises, seek advice early.

Common Scenarios Employers Ask About

What If A Casual Refuses To Provide Evidence?

If a casual seeks unpaid carer’s leave, compassionate leave or FDV leave and refuses to provide reasonable evidence required under the NES, an award or your policy, you may decline to approve that leave. Be clear about the policy upfront and make decisions case‑by‑case, taking into account privacy and sensitivity.

What If A Casual Calls In Sick On A Public Holiday?

If a casual was rostered on a public holiday but is unable to work, there’s generally no payment for a shift not worked. Paid public holiday provisions typically do not apply to casuals unless a specific award or agreement says otherwise.

Can I Ask For A Medical Certificate If A Casual Is Personally Unwell?

There’s no NES entitlement called “unpaid sick leave” for casuals. You can require timely notification of the absence, and - where justified - ask for information to manage WHS risks or address patterns of short‑notice cancellations. Where a leave entitlement is being accessed (carer’s, compassionate or FDV leave), evidence can be requested on the usual “reasonable evidence” standard. For practical boundaries and examples, refer to medical certificates for casual employees.

What About Repeated Short‑Notice Cancellations?

Patterns of unavailability can cause operational strain. A robust policy, clear communication about roster expectations and fair escalation steps help. If problems persist, consider whether performance management, training or roster adjustments are appropriate. Where a casual’s entitlement to paid or unpaid leave has been exhausted or doesn’t apply, practical options are discussed in managing sick leave when entitlements run out and the general rules around leave without pay.

Could Evidence Requirements Be Discriminatory?

They can be if applied harshly or inconsistently. Avoid requirements that disproportionately impact employees based on disability, family responsibilities or FDV circumstances. Handle all information confidentially and limit internal sharing to those who need to know.

How Do Awards And Agreements Fit In?

Modern awards and enterprise agreements can add rules on notice and evidence, especially in industries with heavy casual work. Always check the applicable instrument alongside your policy.

Build A Clear Workplace Policy And Contracts

Clear documentation reduces disputes and helps your team know what to expect. We recommend having a simple absence and evidence policy within a Staff Handbook, aligned with the NES and any applicable award or agreement.

What To Include In Your Policy

• How and when casuals must notify you if they can’t work a shift.
• Which entitlements may apply (unpaid carer’s leave, compassionate leave and paid FDV leave for casuals) and the circumstances for each.
• What “reasonable evidence” looks like for each entitlement and when it’s required.
• How you’ll handle privacy, sensitive information and record‑keeping.
• When a medical clearance may be requested for WHS reasons.
• How patterns of unavailability or repeated short‑notice cancellations will be addressed.

A tailored Staff Handbook can bundle these rules with your other workplace policies so they’re consistent and easy to follow.

Get Your Employment Documents In Order

• Employment Contract: Sets out the casual engagement terms, including classification, hourly rate and casual loading, rostering expectations, and reference to applicable awards and policies.
• Workplace Policy (within your Staff Handbook): Covers notice, evidence, privacy and process for absences and leave.
• Record‑Keeping Process: A simple, secure system to log notifications, approvals and evidence, in line with privacy and Fair Work requirements.

Well‑drafted documents make it clear how casual absences are handled and help you apply the rules consistently across your team.
