Leave balances are one of the easiest things to get wrong in Australian payroll, and one of the most expensive. An employee who believes they have three weeks of annual leave banked, only to be told they have one, loses trust fast. A final pay that under-counts accrued leave can trigger a Fair Work complaint. And a spreadsheet that quietly drifts out of sync over months can leave you liable for back-pay you never budgeted for.
Getting it right starts with understanding how leave accrues and then keeping an accurate running balance for every employee. This guide explains how annual leave and personal leave build up under Australian law, how to handle part-time and casual staff, and how to track balances so they always reconcile. We'll also cover payout obligations and the mistakes that cost businesses the most. For teams that want to stop doing this by hand, leave management software accrues balances automatically and keeps requests, approvals, and records in one place.
Quick summary
- Full-time staff accrue four weeks of annual leave and 10 days of personal/carer's leave each year
- Leave accrues progressively across the year, not in a lump sum on an anniversary
- Part-time staff accrue leave pro-rata, scaled to their ordinary hours
- Unused annual leave must be paid out on termination; personal leave is not
How employee leave accrues in Australia
The National Employment Standards set the minimum leave entitlements for most employees. Two types of paid leave accrue continuously, and understanding how each builds up is the foundation of an accurate balance.
Annual leave: four weeks
Full-time employees are entitled to four weeks of paid annual leave per year of service—20 days for a standard five-day week. Certain shift workers receive five weeks. Leave accrues progressively as ordinary hours are worked, so a full-time employee builds about 2.923 hours per 38 ordinary hours.
Personal/carer's leave: 10 days
Full-time employees accrue 10 days of paid personal (sick) and carer's leave each year. Like annual leave, it accrues progressively throughout the year and any unused balance rolls over to the next year rather than expiring. It is not paid out when employment ends.
The key word is progressively. Leave does not appear in a single lump on an employee's anniversary; it builds up with every ordinary hour worked. That is why a balance changes every pay run, and why accurate tracking matters from an employee's first day. If you want to work through the underlying figures, our guide on how to calculate leave entitlements walks through the accrual formula step by step.
Pro-rata leave for part-time staff
Part-time employees receive the same leave entitlements as full-time staff, just scaled to the hours they actually work. The four-week annual leave entitlement is identical as a proportion; what changes is the number of hours that proportion represents.
A part-time employee working 19 hours a week—half of a 38-hour full-time week—accrues exactly half the annual leave hours of a full-time colleague. The accrual rate is the same per ordinary hour; fewer hours simply means fewer hours of leave. This is why leave accrual should always be driven by ordinary hours worked rather than a fixed weekly figure, especially for staff whose hours vary.
Worked example
A full-time employee on 38 hours per week accrues about 152 hours of annual leave a year (four weeks). A part-time employee on 19 hours a week accrues about 76 hours over the same period. For staff with irregular hours, the safest approach is to accrue against actual ordinary hours each pay run. Our guide on how to calculate pro-rata leave shows the full method with examples.
Casual employees are treated differently again: they generally do not accrue paid annual or personal leave, receiving a casual loading instead. Getting the employment type right in your records is the first step to an accurate balance—accruing leave for a casual, or failing to accrue it for a part-timer, is a common and costly error.
How to track leave balances accurately
Every leave balance comes down to four figures. Get these right for each pay period and the running balance stays correct indefinitely:
Opening balance
The leave the employee had banked at the start of the period. For a new period this is simply the previous period's closing balance, which is why an error in one period quietly carries forward into every period after it.
Leave accrued
The leave earned during the period, based on ordinary hours worked. For full-time staff this is steady; for variable-hours staff it changes each pay run and must be recalculated against actual hours.
Leave taken
The leave used during the period, recorded against the correct category—annual, personal, or carer's. Miscategorising leave taken is a frequent source of balance errors, because each type has its own rules.
Closing balance
Opening balance plus accrued minus taken. This figure becomes next period's opening balance, so it is worth reconciling against payslips regularly to confirm the numbers still tie out.
The manual tracker option
If you only have a handful of staff, a spreadsheet can work as a starting point. A structured template removes the risk of broken formulas and keeps accrual, taken, and closing figures in one place. Our free leave & super tracker gives you a ready-made Excel sheet to record balances per employee and per leave type.
The catch with manual tracking is that it relies on someone updating it accurately every single pay run. A missed entry, a copy-paste error, or a formula overwritten by mistake can throw a balance out by days—and the error compounds because each closing balance feeds the next opening balance. As headcount grows, the safer path is software that accrues automatically and lets employees see their own balance and request leave online.
Payout obligations when employees leave
When employment ends, accrued but unused annual leave must be paid out in the final pay. This is a legal obligation, not a discretionary benefit, and it is one of the most scrutinised parts of a termination pay:
- Annual leave is paid out. Any accrued but untaken annual leave is paid at the employee's base rate for the ordinary hours it represents, plus any annual leave loading that would have applied.
- Personal and carer's leave is not paid out. Although it accrues and rolls over during employment, unused personal leave is forfeited on termination.
- Long service leave may apply. Depending on the state or territory and the employee's length of service, accrued long service leave may also need to be paid out.
Because the annual leave payout is driven directly by the closing balance, an inaccurate running balance becomes an inaccurate final pay. This is exactly where loose tracking turns into a financial and compliance risk. For the authoritative rules on entitlements and termination pay, the Fair Work Ombudsman is the definitive source.
Common leave tracking mistakes
A few recurring errors account for most leave balance disputes. Knowing them helps you design a process that avoids them:
Accruing on the wrong hours
Accruing leave against rostered or contracted hours instead of actual ordinary hours worked drifts out over time, especially for staff whose hours vary. Always accrue against ordinary hours.
Miscategorising leave taken
Recording personal leave against the annual leave balance (or vice versa) corrupts both balances. Each leave type has its own rules and payout treatment, so categorisation must be exact.
Forgetting leave loading
Where an award or agreement provides annual leave loading, it generally applies to leave taken and to leave paid out on termination. Omitting it understates pay and creates back-pay risk.
Never reconciling balances
Letting balances run for months without checking them against payslips lets small errors compound into large ones. Reconcile regularly so a closing balance never strays from reality.
Frequently asked questions
How much annual leave do Australian employees accrue?
Full-time employees accrue four weeks of paid annual leave per year—20 days for a standard five-day week, with certain shift workers entitled to five weeks. Leave accrues progressively, at roughly 2.923 hours for every 38 ordinary hours worked.
Does annual leave accrue for part-time employees?
Yes. Part-time employees accrue annual leave on a pro-rata basis according to their ordinary hours. The proportion is the same as full-time; the hours accrued are simply scaled to the hours worked.
How do I track an employee leave balance?
Use four figures each period: opening balance, leave accrued, leave taken, and closing balance. Opening plus accrued minus taken equals the closing balance, which becomes the next period's opening balance. A spreadsheet works for small teams; software is more reliable as you grow.
Do I have to pay out unused annual leave when an employee leaves?
Yes. Accrued but unused annual leave must be paid out in the final pay at the employee's base rate for the ordinary hours involved, plus any annual leave loading that would have applied.
Does personal or carer's leave get paid out when it is unused?
No. Personal and carer's leave accrues and rolls over during employment but is not paid out on termination. Only accrued annual leave, and long service leave where applicable, must be paid out.
Can employees go into a negative leave balance?
An employer can agree to advance leave before it accrues, creating a negative balance, but this is discretionary and should be documented. Where there is a written agreement, advanced leave can generally be recovered from final pay. Accurate tracking prevents accidental negative balances.
