Understanding your sick leave entitlements in Australia

In Australia, sick leave is officially known as “Personal/Carer’s Leave”, a fundamental workplace right protected under the National Employment Standards (NES). Most workers refer to it as sick leave or sick pay, but the official definition is broader. It applies to your own illness or injury, and may also cover caring for an immediate family or household member who is unwell or facing an emergency.

The baseline entitlement is clear: 

  • Full-time employees are entitled to 10 days of paid sick leave per year.
  • Part-time employees receive a pro-rata amount based on their ordinary hours of work. 
  • Casual employees do not accrue paid sick leave. Their compensation is generally reflected in the 25% casual loading added to their hourly rate. 

 

This entitlement starts accumulating from your very first day of employment and carries over from year to year with no expiry and no cap. You can access it immediately, although your employee can request supporting evidence, such as a medical certificate. 

How to calculate your sick leave (The 1/26 formula) 

The way sick leave is calculated in Australia changed significantly after the landmark *Mondelez v AMWU* High Court decision. The decision confirmed that leave should be based on an employee’s ordinary hours worked, not a fixed number of calendar days. 

This ensures entitlements are proportionate. For example, a part-time worker doing 4-hour days should not receive the same 10 “days” as a full-time worker doing 8-hour days; their entitlement should reflect their actual time worked.

The official formula under the Fair Work Act is:

(Ordinary weekly hours × 52.18) ÷ 26 

If you are looking for a sick leave calculator 38 hour week breakdown, here is exactly how the numbers work:

  • Multiply your weekly hours by 52.18 (the average number of weeks in a year): 38 × 52.18 = 1,982.84 hours. 
  • Divide that figure by 26: 1,982.84 ÷ 26 = 76.26 hours. 
  • Result: A full-time employee on a 38-hour work week accrues approximately 76 hours of paid sick leave per year, which is the equivalent of 10 standard working days.

To make this easier to understand, let’s look at two real-life examples: 

Example 1: Sarah (Part-time employee)

Sarah works part-time for 20 hours per week. To find her yearly sick leave entitlement, we use the formula: (20 × 52.18) ÷ 26 = 40.14 hours per year. Because Sarah works fewer hours, her sick leave accrues proportionally, giving her roughly 5 working days of sick leave based on her specific hours. 

Example 2: John (Rotating Roster) 

John works full-time, but his hours vary across a rotating fortnight (e.g., 40 hours one week, 36 hours the next). Because his average ordinary hours are 38 hours per week, he still accrues the standard 76 hours of sick leave per year. However, when John takes a sick day on a 10-hour shift, 10 hours are deducted from his balance, not the standard 7.6 hours.  

How much sick leave do you accrue per week?  

Sick leave is not credited as a lump sum at the start of each year. As you work, you progressively accrue leave each week. For a full-time employee working 38 hours a week, the numbers break down like this:

  • Per week: Accrues 1.46 hours (Approx. 0.19 days) 
  • Per month: Accrues 6.35 hours (Approx. 0.83 days) 
  • Per year: Accrues 76 hours (Exactly 10 days) 

This gradual accrual system is especially important during your first year of employment. For example, if you start working in July and need a week off in August, you may not yet have built up your full 76-hour entitlement. Your employer may agree to let you access leave in advance, but that is at their discretion.   

The good news: Once that leave is in your bank, it stays there. Unused sick leave carries over and accumulates year after year, with no cap. 

5 Key rules for Australian sick leave

Understanding sick leave goes beyond knowing the basics; there are a few important rules every Australian worker should know. 

1. Unused sick leave accumulates indefinitely 

Yes, sick leave does accumulate. Any personal or carer’s leave you don’t use carries over to the next year. There is no “use it or lose it” rule. Over time, this can build up into a substantial leave balance. 

2. Employers can request a medical certificate for any absence 

Under Fair Work rules, your employer has the right to ask for reasonable evidence, like a medical certificate, to support a sick leave claim, even for a single day. They cannot ask for a medical certificate before you take sick leave, but they can request evidence afterwards to approve and pay your leave. If you do not provide the requested proof within a reasonable time, your employer may refuse to pay for the absence. 

If you cannot go to a clinic, Hola Health provides online medical certificates from Australian-registered doctors, available 24/7 and delivered digitally. 

3. Mental health days count as sick leave 

Mental health conditions, including stress, anxiety, depression, or burnout, are valid reasons for taking paid sick leave under Australian employment law. They are treated the same as physical illnesses, with the same rights and protections. You don’t need to share detailed personal information with your employer; you simply need to provide appropriate evidence if requested.

4. Sick leave is not paid out when you resign 

Unlike annual leave, unused sick leave does not convert into a payout when your employment ends, whether you resign, are made redundant, or are dismissed. Many Australians mistakenly believe sick leave is paid out when employment ends, but this generally only happens if a specific employment agreement or contract allows it, which is uncommon.  

5. If you are sick on a public holiday, it counts as a public holiday 

If you fall sick on a day that is already a public holiday, the absence is treated as a public holiday, not as a sick day. Your sick leave balance stays the same, which can be a valuable advantage over time.  

What happens if I run out of sick leave? 

Exhausting your sick leave balance while you are still unwell can be stressful, but there are several options available: 

  • Take unpaid sick leave: Importantly, under the Fair Work Act, employees are generally protected from dismissal during a temporary illness-related absence, provided they supply the required evidence. However, these protections do have limits, especially for extended absences.
  • Negotiate to use annual leave: With your employer’s approval, you can use annual leave to cover the absence and continue receiving your normal pay. Many employers are open to this to avoid the administrative complexity of unpaid leave.  
  • Check your income protection: If you are off work for an extended period due to illness or injury, your income protection insurance may help replace part of your income.  This cover is often included with super funds, so it is worth checking your policy. 
  • Speak to your employer early: If you feel that a health issue is going to keep you off work for an extended period, communicate with your employer as soon as possible. Many workplaces are flexible, and early conversations often lead to better outcomes than last-minute requests.  

Sick Leave Calculator FAQs

Common questions about calculating your entitlements in Australia.

Full-time employees in Australia are entitled to 10 days of paid sick leave (personal/carer’s leave) per year. This equates to 76 hours for a standard 38-hour week, calculated using the formula:

(ordinary weekly hours x 52.18) ÷ 26.

Part-time employees receive a pro-rata amount based on their ordinary hours. Casual employees do not accrue paid sick leave.

Yes, sick leave (personal/carer’s leave) starts building from your first day of work and rolls over year after year. There is no expiry date or cap on unused leave under the same employer. However, it is not paid out upon termination of your employment. This means your unused sick leave cannot be paid out if you resign or are made redundant, unless your workplace agreement specifically permits it.

No, casual employees in Australia do not accrue paid sick leave. They receive a casual loading (typically 25%) to compensate for not having paid leave entitlements.

Casual employees, however, are entitled to 2 days of unpaid carer’s leave per occasion when an immediate family member requires care due to illness or emergency.

When you take sick leave, you are paid at your normal base rate for your usual working hours, excluding overtime, allowances, bonuses, or penalty rates.

To calculate your total annual sick pay entitlement, multiply your base hourly rate by your annual sick leave entitlement in hours (e.g., 38 hours/week worker: $35hr x 76 hrs + $2,660 per year in sick pay value).

An employer cannot reject a valid sick leave if you have an available balance and have provided the required notice and evidence. However, they can choose not to pay for the absence if you fail to provide evidence when requested or if you do not follow the workplace’s notification rules.

You cannot be compelled to work if you are genuinely unwell, and the Fair Work Act protects employees who need temporary leave due to illness.

No. Weekends do not count as sick days unless you were meant to work on those days. Sick leave only applies to your ordinary working hours. For example, if you fall sick on a Friday afternoon and recover by Monday, only Friday (or the portion of Friday you missed) would be counted as sick leave.

Yes. mental health conditions, including stress, anxiety, depression, burnout, or panic attacks, are treated the same as physical illness under the National Employment Standards. You can use your paid sick leave for mental health days. However, your employer may request evidence of your condition if you take time off for mental health reasons. A certificate from a GP, psychologist, or other registered health professional confirming you were unfit for work is sufficient.

There is no set limit on how many times you can use your sick leave, as long as your leave is genuine and supported by evidence when requested. However, frequent absences can raise concerns, and if your employer is convinced your sick leave is being misused, they may request medical certification for every absence.

Generally, routine check-ups and planned medical appointments are not covered by sick leave, as it is intended for illness or injury. In practice, however, some employers are flexible and allow employees to use sick leave for medical appointments. Check your workplace policy or agreement.

A personal leave calculator is the same as a sick leave calculator. In Australia, sick leave is officially called “personal/carer’s leave” under the National Employment Standards.

There are several generic leave calculators. Here is what makes ours different.

Yes, you continue to accrue sick leave (personal/carer’s leave) while you are taking paid annual leave. Under the National Employment Standards (NES), any period of paid leave counts as continuous service, meaning your sick leave balance will keep growing while you are on holiday.

If you fall ill or sustain an injury while on paid annual leave, you can use your sick leave instead. You will need to notify your employer and provide a medical certificate. Your employer must then re-credit your annual leave balance for the days you were sick and deduct them from your sick leave balance instead.

No, sick leave does not accrue while you are taking unpaid leave, including unpaid parental leave, unpaid sick leave, or government-funded Paid Parental Leave (PPL). Accrual pauses during these periods and resumes as soon as you return to paid work.

Your employer cannot force you to take unpaid leave if you are sick and still have a positive paid sick leave balance. However, if your paid sick leave runs out and you remain unfit for work, you will transition to unpaid sick leave.

Yes, a certificate issued by a registered pharmacist is generally accepted as valid medical evidence for minor ailments (such as a cold, flu, or gastroenteritis) under the Fair Work Act. However, for serious conditions or extended absences, employers usually require a certificate from a registered medical practitioner (like an online doctor or GP).

Part-time workers receive a pro-rata amount of the 10 days full-time workers get, based entirely on the hours they work. For example, if you work exactly half the hours of a full-time employee (19 hours per week), you will accrue 38 hours of sick leave per year, which equates to 5 of your normal working days.

Generally, you cannot use sick leave for purely elective or cosmetic procedures. Sick leave is strictly for when you are unfit for work due to a personal illness or injury. However, if a cosmetic procedure is deemed medically necessary by a doctor, or if you suffer unexpected medical complications following an elective surgery that render you unfit for work, sick leave may apply.

There is no difference in the balance. Under the NES, “personal/carer’s leave” comes out of the exact same pool of hours. You can use your 10 days (76 hours) either for your own illness (personal leave) or to care for an immediate family or household member who is sick or facing an unexpected emergency (carer’s leave).
