How Is Annual Leave Calculated in NSW?

If you’re running a business in New South Wales, getting annual leave right is essential. It keeps your team happy, reduces payroll headaches, and helps you avoid compliance issues.

But the rules can feel confusing-especially if you have a mix of full-time, part-time, and shiftwork arrangements.

In this guide, we’ll break down exactly how annual leave is calculated in NSW (good news: it’s mostly governed by national rules), what to include in annual leave pay, and the simple formulas you can use to stay compliant day to day.

What Do NSW Employers Need To Know About Annual Leave?

Annual leave entitlements for most NSW employees are set by the National Employment Standards (NES) under the Fair Work Act. That means the core rules are the same across Australia.

Here are the essentials you should keep in mind:

• Full-time employees are entitled to 4 weeks of paid annual leave per year of service (based on their ordinary hours).
• Certain shiftworkers are entitled to 5 weeks per year (depending on the relevant award or agreement definition of shiftwork).
• Part-time employees accrue annual leave on a pro-rata basis according to their ordinary hours.
• Casual employees generally do not receive paid annual leave.

Accrual happens progressively during the year based on ordinary hours of work and accumulates from year to year if not taken.

Annual leave continues to accrue during paid leave (for example, paid annual leave or paid personal/carer’s leave). It doesn’t usually accrue during periods of unpaid leave, such as unpaid parental leave. If an employee is away on workers’ compensation, whether leave accrues can depend on the circumstances and applicable industrial instruments-get advice if this applies to your business.

How Is Annual Leave Accrued And Calculated?

Annual leave accrues based on an employee’s ordinary hours of work. The simplest way to think about it is in hours, not days.

Standard Accrual Rates

• Full-time (38-hour week): 4 weeks x 38 hours = 152 hours per year.
• Accrual per week (full-time): 152 ÷ 52 ≈ 2.923 hours per week.
• Accrual per hour (full-time): 152 ÷ (38 x 52) = 0.076923 hours per ordinary hour worked.
• Shiftworker (5 weeks): 5 x 38 = 190 hours per year, ≈ 3.654 hours per week, ≈ 0.096153 hours per ordinary hour.

For part-time employees, multiply 4 weeks by their average ordinary hours per week (or 5 weeks if they’re a qualifying shiftworker) to get their annual entitlement in hours.

Quick Formulas You Can Use

• Annual entitlement (hours) = 4 weeks x ordinary weekly hours (or 5 weeks for applicable shiftworkers).
• Weekly accrual (hours) = annual entitlement (hours) ÷ 52.
• Hourly accrual = annual entitlement (hours) ÷ total ordinary hours in a year.

Worked Examples

Example 1: A full-time employee works 38 ordinary hours per week.

• Annual entitlement = 4 x 38 = 152 hours.
• Weekly accrual ≈ 2.923 hours.
• If they work all year, they’ll accrue 152 hours of annual leave.

Example 2: A part-time employee works 20 ordinary hours per week.

• Annual entitlement = 4 x 20 = 80 hours.
• Weekly accrual ≈ 1.538 hours.

Example 3: A shiftworker (as defined under the applicable award) works 38 ordinary hours per week.

• Annual entitlement = 5 x 38 = 190 hours.
• Weekly accrual ≈ 3.654 hours.

Tip: Use hours, not “days,” in your payroll system. Employees have different “day” lengths, so tracking in hours avoids underpayments or confusion.

How Do You Calculate Annual Leave Pay (Including Loading)?

When an employee takes annual leave, you must pay them at their base rate of pay for their ordinary hours during the period of leave. Base rate excludes things like overtime, penalties, and allowances.

Some awards and enterprise agreements also require annual leave loading (often 17.5%) during periods of paid annual leave. Check your modern award or agreement to confirm whether annual leave loading applies to your team.

Public Holidays During Annual Leave

If a public holiday falls during a period of annual leave, the day is treated as a public holiday (not annual leave), so you don’t deduct that day from the employee’s annual leave balance.

Cashing Out Annual Leave

In many cases, employees can cash out annual leave if certain conditions are met (usually requiring a written agreement and minimum balances). Make sure your approach aligns with the NES and any applicable award or agreement. If it’s something you offer, build clear rules into your policies and forms-our overview of cashing out annual leave explains the guardrails.

Part-Time, Shiftwork And Irregular Hours: Employer Scenarios

Part-Time Employees

Part-time employees accrue leave pro rata based on their ordinary hours. If hours vary, calculate accruals against the actual ordinary hours worked in each pay cycle and keep accurate records.

Shiftworkers

Not every employee who works shifts is a “shiftworker” entitled to 5 weeks. The definition depends on the relevant award or agreement (for example, rotating shifts or regularly working Sundays and public holidays). Confirm the definition that applies to your workplace before applying the 5-week entitlement.

Irregular Or Changing Rosters

If you change rosters regularly, ensure your payroll system accrues leave based on ordinary hours in each period. Where an employee’s pattern changes permanently (for example, from 25 hours to 30 hours per week), their future accruals should reflect the new ordinary hours. Consider addressing these mechanics in your Employment Contract and policies so expectations are clear.

Leave In Advance And Negative Balances

You can agree to employees taking annual leave in advance. Document the arrangement and keep balances transparent. If this results in a negative balance, make sure your approach to recovery is lawful and clearly set out in your policies-practical tips in our guide to managing negative leave balances can help you avoid disputes.

Managing Annual Leave In Your Business

Good systems and clear documents save time and reduce risk. Here’s how to keep annual leave under control as you grow.

1) Lock In Clear Employment Terms

Your contracts should set out the basics: classification, hours of work, ordinary hours framework, and how leave requests are made and approved. A well-drafted Employment Contract is your first line of defence against confusion.

2) Adopt Practical Leave Policies

Put simple, easy-to-follow rules in your handbook or policies. Cover how to apply for leave, notice requirements, peak-period blackout dates (if any), cashing out rules, and what happens with leave in advance. If you don’t already have one, a tailored Workplace Policy or Staff Handbook keeps everything consistent.

3) Use Hours-Based Payroll Settings

Configure your payroll and rostering tools to accrue leave in hours, not days. Check that accrual rates are accurate for each employee type (4 or 5 weeks), and review balances regularly, especially after role or roster changes.

4) Keep Solid Records

Keep records of leave requests, approvals, balances, and any agreements to take leave in advance or cash out leave. If there’s ever a dispute or an audit, these records are crucial.

5) Plan For Peak Periods

If your business has seasonal peaks, set reasonable rules for leave during those times. You can direct an employee to take annual leave in certain circumstances (for example, during a shutdown) if it’s reasonable and consistent with the award or agreement that applies.

Common Pitfalls And How To Avoid Them

Relying On “Days” Instead Of Hours

Different employees have different day lengths. If you track in “days,” you can accidentally over- or under-deduct leave. Hours-based tracking is more accurate and fair.

Forgetting Leave Loading

Where an award or agreement requires annual leave loading, you must pay it-failing to do so can amount to underpayment. Confirm your obligations for annual leave loading and set up payroll properly.

Not Accounting For Public Holidays

Don’t deduct annual leave on public holidays. This is a common error that’s easily avoided with a quick balance check before processing payroll.

Unclear Processes For Leave In Advance Or Cashing Out

Both are lawful in many cases, but only with strict written agreements and minimum balances. Build a simple checklist and keep your Workplace Policy aligned with the NES and applicable awards.

Mistakes On Termination

On termination, you must pay out any unused annual leave at the correct rate (including any applicable loading). Double-check your awards and follow a clear process-our guide to calculating final pay and practical notes on annual leave on resignation can help you get this right the first time.

Key Takeaways

• Annual leave in NSW is governed by national rules: 4 weeks per year for most full-time staff (5 weeks for qualifying shiftworkers) and pro rata for part-time employees.
• Always calculate and track annual leave in hours based on ordinary hours-it’s more accurate and reduces payroll errors.
• Leave pay is at the base rate for ordinary hours, and many awards require annual leave loading, so check your industrial instrument.
