Managing leave for part-time staff in Australia
Reviewed by Mellow Editorial Team, HR & payroll content team
Part-time employees in Australia accrue leave on a pro-rata basis — they get the same entitlements as full-time staff, just scaled to their ordinary hours. Understanding how to calculate and manage that correctly protects you from underpayment claims and keeps your team informed.
How part-time leave entitlements work
The National Employment Standards set the floor for leave in Australia. Full-time employees are entitled to four weeks of paid annual leave per year. Part-time employees receive the same four weeks, but measured in hours rather than weeks.
That distinction matters. A part-time employee working three days a week has a shorter working day "week" than a full-timer. Their four weeks of leave equals four times their ordinary weekly hours — not four times 38.
For example, if someone works 15 hours a week, their annual leave entitlement is 60 hours per year (15 × 4). A full-timer on 38 hours accrues 152 hours. Both are entitled to "four weeks" — the hours just differ.
Annual leave accrual for part-time staff
Annual leave accrues continuously throughout the year, not in a lump sum on the anniversary date. Part-time employees accumulate leave proportional to the hours they work.
If hours vary week to week — common with part-time arrangements — accrual should be calculated on actual hours worked each pay period, not an estimated average. Most modern payroll systems handle this automatically, but it is worth confirming your setup is capturing real hours rather than a fixed estimate.
Unused leave carries over from year to year. Employees can accumulate a significant balance if leave is not actively managed. Some awards and enterprise agreements allow employers to direct employees to take leave if the balance becomes excessive — check the relevant modern award to understand what applies.
Personal leave and other entitlements
Part-time employees also receive personal leave (sick and carer's leave) on a pro-rata basis. The full-time entitlement under the NES is ten days per year. A part-time employee receives a proportional amount based on their ordinary hours.
Again, because leave is expressed in hours, a part-time employee on 15 hours a week receives roughly 30 hours of personal leave per year (10 days × 3 hours per day, assuming five-hour shifts — adjust for their actual shift length).
Compassionate leave and community service leave apply equally to part-time employees without pro-rating. Public holidays work differently too: a part-time employee is only entitled to a paid public holiday if they would ordinarily have worked that day. If a public holiday falls on a day they do not work, there is no entitlement and no substitute day off.
Managing roster changes and leave balances
A common source of confusion is what happens when a part-time employee's hours change. If someone moves from three days to four days a week, their future accrual rate increases, but their existing balance stays as it was. You do not retroactively adjust past accruals.
More complex is when an employee takes leave spanning a period with different hours. The general principle is that leave is paid at the ordinary rate applicable during the leave period, based on the current contracted hours. If there is any ambiguity, the relevant award or enterprise agreement may specify how to handle it — check before you pay.
Keeping clear written records of contracted hours and any changes to those hours is essential. If a dispute arises later, you need to demonstrate what was agreed and when.
Payroll and record-keeping obligations
Under Single Touch Payroll, you report leave entitlements and payments to the ATO at each pay event. Part-time leave balances should be tracked accurately in your payroll system, because errors compound over time and can result in underpayment liabilities that are expensive to unwind.
Each payslip should show the employee's current leave balance in hours. For part-time staff in particular, showing balances in hours (rather than days) avoids confusion, since "a day" means different things depending on how many hours they work on that day.
Employees are entitled to access their leave records on request. Under the Fair Work Act, employers must retain time and wages records for seven years. That includes records of leave accruals, leave taken, and any agreements about leave (such as cashing out or directing leave).
At the end of the financial year, STP finalisation must be completed by 14 July. This is also a good point to review leave balances across your part-time workforce and flag anyone with an excessive accumulation before it becomes a larger liability.
When an employee leaves
On termination, any accrued but untaken annual leave must be paid out, regardless of the reason for separation. The payout is calculated on the employee's current ordinary pay rate — for part-time staff, that means their contracted hours at their current rate, not some average of past arrangements.
Personal leave is not paid out on termination. It simply lapses.
