NSW's ten-year Act
New South Wales runs the country’s oldest long service leave law still in force, the Long Service Leave Act 1955 (NSW). A full, takeable entitlement of 2 months accrues after 10 years of continuous service, which the Act itself defines as 8⅔ weeks (s4(2)(a3)), a figure that continues to accrue at the same rate for every 5 years served after that. Worked as a straight weeks-per-year rate, that’s roughly 0.8667 weeks for every year of continuous service. The calculator above applies that rate to the length of service entered.
Two different tests before ten years
NSW doesn’t simply switch the entitlement on at 10 years and off before it. From 5 years, a pro-rata payment becomes payable on termination, but only if that termination is for a qualifying reason: the employer ending the job for any reason other than the worker’s serious and wilful misconduct, the worker resigning because of illness, incapacity, or domestic or other pressing necessity, or the worker’s death. A worker who simply resigns to take another job at, say, 7 years’ service gets nothing under this test. That changes at 10 years: from that point, a pro-rata payment is payable if employment ends for any reason at all, including a plain resignation. It’s a genuinely two-tier system, and the gap between 5 and 10 years is exactly where a lot of NSW workers assume they have an entitlement they don’t.
Continuous service, and what doesn't break it
Continuity survives approved leave (paid or unpaid, under the terms of employment), illness or injury absence, an employer-caused interruption made specifically to dodge the Act’s obligations, an industrial dispute, slackness of trade, and any other employer-ended gap where the worker is re-employed within 2 months. Two structural provisions are easy to miss: an apprenticeship counts toward service if the same employer re-engages the worker within 12 months of it finishing, and a transmission of business (the employer selling, transferring or otherwise handing the business to someone else) carries the worker’s accrued service across to the new employer rather than resetting the clock. A transfer between a holding company and its subsidiary within 2 months of termination gets the same protection.
What counts as ordinary pay
For a worker on a fixed rate, NSW pays the greater of the current ordinary rate or the average weekly rate over up to the preceding 5 years. For anyone paid otherwise (commission, piecework, casual loading), the calculation averages the preceding 12 months or 5 years, whichever is greater, plus the average of any bonuses over the same period, plus the cash value of any board or lodging provided. That’s a more generous averaging window than several other states use, and it matters most for workers whose pay has grown over a long tenure. The calculation looks backwards far enough to capture that growth rather than freezing at whatever the rate happened to be on the day leave is taken.
In practice
Take a tradesperson who has worked for the same NSW employer for eight years and resigns to take a better-paying job elsewhere. Under the two-tier test above, that’s a plain resignation at 8 years (past the 5-year gate but short of the 10-year any-reason mark), so nothing is payable unless the move was genuinely driven by illness, incapacity or a domestic or other pressing necessity. The same worker made redundant at 8 years, by contrast, is covered: an employer-initiated termination for a reason other than serious misconduct is one of the qualifying reasons from 5 years onward. Two employees with identical service, two very different outcomes, entirely down to why the job ended, which is precisely why this calculator reports a guaranteed figure and a separate conditional one rather than a single number that can’t tell the two situations apart.
After ten years: the 15- and 20-year checkpoints
NSW doesn’t stop counting once the first entitlement lands at 10 years. Every further 5 years of continuous service earns another month, 4⅓ weeks under s4(2)(a3)’s own definition, stacked on top of the original 2 months from year 10. Someone still with the same employer at 15 years has 3 months owing in total. At 20 years, 4 months. Worked back to an annual rate, that holds at the same roughly 0.8667 weeks a year the whole way through, which is exactly why the calculator above doesn’t switch to a different multiplier once someone passes ten years. It just keeps applying the same rate.
There’s a detail worth knowing if leave balances get tracked in a spreadsheet between milestones. The Act grants these amounts in blocks, at year 10, then 15, then 20 and so on, not as a smooth weekly trickle. A running total shown mid-cycle is a planning figure, useful for budgeting, nothing more. Nothing has technically vested at year 12 or 13 unless a qualifying termination triggers the pro-rata rules covered above. It’s a small distinction. It matters anyway if a bookkeeper is trying to reconcile an accrual line against what the Act actually owes on a specific date, especially around an EOFY payroll reconciliation when someone’s asking why the balance on the payslip doesn’t match what a calculator just told them.
A second scenario: redundancy well past ten years
Take a different case from the resignation example above: 17 years with the same NSW employer, made redundant in a restructure. The 10-year any-reason mark was passed long ago here, so unlike the 8-year resignation scenario, the reason for ending the job doesn’t need checking at all. Redundancy, retirement, being let go for underperformance. Once ten years is behind someone, it’s owed regardless.
What takes more care is the amount. Two months accrues at year 10, then another month lands at 15. At 17 years, the employee is two years into the next five-year block, so the true figure sits somewhere between the 15-year and 20-year totals rather than at either one. That’s not something worth eyeballing with a calendar and a rough guess. Run the actual service dates through the calculator above rather than rounding to the nearest milestone, because a wrong guess in either direction either shortchanges someone or overpays them.
Who to contact if a NSW employer won’t pay it
If a NSW long service leave payment is disputed, or simply isn’t turning up in the final pay run, NSW Industrial Relations is the first stop. It publishes guidance on the Act and can point a worker toward the Industrial Relations Commission if a formal dispute is needed. Employers get the same benefit in reverse. It’s the same body that can confirm whether a specific set of dates and circumstances actually triggers an entitlement, rather than guessing from a summary like this one.
This is general information, not a substitute for that check. A calculator can apply a formula. It can’t read an employment contract, and it can’t confirm a termination reason was genuine, which is exactly what NSW’s two-tier test above turns on.
The mix-up: assuming NSW’s gate works like Western Australia’s
One mistake worth naming directly, because it comes up whenever someone compares notes across states: NSW’s early pro-rata gate is restricted to specific reasons, illness, incapacity, domestic or other pressing necessity, an employer-initiated ending, or death. Western Australia’s equivalent gate, by contrast, covers any reason at all except an employer dismissing someone for serious misconduct, plain resignation included. On paper they look almost the same shape: a five-years-then-ten structure sitting next to a seven-years-then-ten one.
Treat them as interchangeable, though, and a NSW employer can end up assuming a resigning employee at 7 years is owed something they’re not actually entitled to until year 10. Or a worker can walk away thinking they’ve missed out on nothing, when a genuine domestic necessity might have qualified them from year 5. Worth reading NSW’s own reason test carefully rather than applying a rule of thumb picked up from a different state’s Act, even one that looks like a close cousin.
Getting the record right
Getting any of this right by hand, across a handful of long-tenured staff, is exactly the kind of record-keeping that drifts once it’s spread across a spreadsheet and a filing cabinet. Delta Infotech’s business systems work exists for precisely that gap, and it’s priced openly on the pricing page.
