Overtime comes up a lot for small businesses – especially when things get busy, a big order lands, or you’re covering staff leave. If your team regularly stays back or starts early, it’s natural to ask: is it illegal not to pay overtime in Australia? And what if someone “doesn’t mind” staying late – does that change anything?
Getting overtime right isn’t just about avoiding complaints. It’s about paying people properly, setting clear expectations, and keeping your business on the right side of the law. The good news is that once you understand the rules, it’s much easier to put simple systems in place and operate with confidence.
In this guide, we’ll break down what overtime actually means in Australia, when it must be paid, common scenarios that cause confusion, how TOIL works, and practical steps to keep your payroll compliant.
What Counts As Overtime In Australia?
Overtime isn’t just “extra work” – it has a specific meaning under Australian workplace instruments. In most cases, overtime is work performed:
- Beyond the ordinary hours prescribed by a modern award or registered enterprise agreement
- Outside the span of ordinary hours (for example, late at night or on weekends if the instrument specifies ordinary hours on weekdays only)
- In excess of maximum daily or weekly limits set by the relevant instrument
For many full-time employees covered by an award, ordinary hours are up to 38 per week with rules about when those hours can be worked. Anything beyond those parameters can attract overtime rates.
If no award or enterprise agreement applies, whether extra hours attract “overtime” pay comes down to the employee’s contract terms. The National Employment Standards (NES) set maximum weekly hours and require that additional hours be reasonable, but the NES by itself doesn’t create an entitlement to overtime penalty rates.
What employees are entitled to be paid, when overtime kicks in, and the rate payable (for example, time-and-a-half or double time) depend on the applicable award, enterprise agreement or contract. If you need a refresher on the broader framework, it can help to read an overview of overtime laws for employers and how different instruments interact.
Is It Illegal Not To Pay Overtime?
In short: yes, if an employee is entitled to overtime under a modern award, enterprise agreement or their employment contract, failing to pay the correct overtime rates is unlawful. Underpayments can lead to back-pay orders, significant civil penalties and, in some jurisdictions, criminal consequences for deliberate wage theft.
The key is to identify what instrument applies to each employee, then follow it. Here’s how that plays out across common situations.
Employees Covered By Awards Or Enterprise Agreements
Most employees are covered by a modern award. Awards set minimum conditions, including when overtime applies, how it’s calculated, minimum breaks between shifts and any rostering rules. If an enterprise agreement applies, its overtime clauses will govern (and must meet or exceed the NES), often with their own rules about approval and record-keeping.
If overtime is worked in circumstances where the award or agreement says it’s payable, you must pay it. Not paying overtime in those circumstances is a breach.
Salaried Employees And “Flat Rates”
Paying a salary or using a “flat rate” doesn’t remove your obligation to meet award entitlements. For award-covered employees on salaries, you must ensure the salary is high enough to compensate for all entitlements the employee would have received under the award – including overtime, penalty rates and allowances – over the relevant period. Many businesses do this with regular reconciliations to check that the salary keeps the employee better off overall in practice.
Some awards include specific annualised wage provisions with strict record-keeping and reconciliation requirements. If you use an annualised wage arrangement, make sure you follow those rules closely. It’s also best practice to set expectations in a well-drafted Employment Contract so everyone is clear on how extra hours are handled.
Important note: the “BOOT” (Better Off Overall Test) is a concept used to assess enterprise agreements, not individual salaries. For individual salaried arrangements, the focus is simply whether you have, in fact, paid at least what the award requires, including any overtime that actually occurred.
Employees Who “Volunteer” To Stay Late
What if your team member says “don’t worry about it” and stays back to finish a task? If you know about the extra work or reasonably ought to know it’s being performed, and the award or agreement would treat those hours as overtime, you still need to pay overtime (unless a valid TOIL arrangement applies). Employees can’t waive minimum entitlements, even if they’re trying to be helpful.
Managers And Award-Free/High-Income Employees
Some senior managers are not covered by an award (for example, because their role isn’t within any award classification or because they’ve signed a valid high-income guarantee above the high-income threshold). In those cases, overtime rates are a matter of contract rather than award. If the contract doesn’t promise overtime, there may be no separate overtime entitlement – but you still need to ensure work hours are reasonable and comply with the NES maximum weekly hours.
Casual And Part-Time Employees
Casuals and part-timers can also attract overtime, but the triggers and rates depend on the award or agreement. For example, a part-time employee may earn overtime if they work beyond their agreed hours or outside the span of ordinary hours. See more detail in this guide to overtime rules for casual employees and how different awards approach minimum engagements, rosters and overtime thresholds.
Genuine Contractors
Independent contractors are not employees and are generally paid according to their commercial terms, not award overtime. However, if someone is misclassified (sham contracting), you can be liable for unpaid employee entitlements, including overtime under the applicable award. Check that your contractor arrangements reflect reality in day-to-day supervision, control and integration into your business.
Can You Offer Time Off In Lieu (TOIL) Instead Of Paying Overtime?
Often, businesses want to give staff flexibility – for example, taking a day off after a busy weekend. Time off in lieu (TOIL) can be a lawful alternative to paying overtime, but only if the rules in the relevant award or enterprise agreement are followed.
TOIL rules differ between instruments, but commonly require:
- A genuine, written agreement between employer and employee each time TOIL is used (or in the form specified by the instrument)
- Accurate records of the overtime worked and TOIL taken
- That TOIL be taken as paid time off, hour-for-hour (not at overtime rates), within a specified period
- Payment at the applicable overtime rate if the TOIL isn’t taken within that period
- That employees cannot be forced to accept TOIL instead of payment
Always check the specific wording in your award or agreement. If TOIL isn’t allowed under the instrument (or if you don’t meet the conditions), you must pay the overtime instead. For an employer-focused walkthrough of process and records, see this practical overview of time in lieu.
What Happens If You Don’t Pay Overtime?
Underpaying overtime can lead to:
- Back-pay orders to repay the full amount of underpayments (often going back several years)
- Penalty interest and civil penalties for each contravention
- Investigations, enforceable undertakings and public contravention notices
There is also increasing focus on wage compliance nationally. Intentional underpayment (wage theft) has been criminalised in some states, and new federal laws strengthen enforcement and introduce criminal offences for deliberate conduct. In short, it’s not worth the risk – it’s both simpler and safer to build robust overtime practices now.
How To Stay Compliant With Overtime (Practical Steps)
Compliance doesn’t need to be complicated. A few clear documents and systems go a long way toward getting overtime right and avoiding disputes.
1) Confirm Coverage And Entitlements
- Identify the correct modern award or enterprise agreement for each role, and read the overtime and rostering provisions closely.
- Where an employee is truly award-free, rely on the contract and ensure the hours worked remain reasonable under the NES maximum weekly hours. For context, here’s an employer guide to maximum weekly hours and what’s considered reasonable additional hours.
- Understand when ordinary hours end and overtime begins (for example, after a certain daily cap or outside the prescribed span of hours).
2) Use Clear Employment Contracts
- Make sure every employee has a tailored Employment Contract setting out classification, hours, pay type (hourly/salary), overtime treatment and any TOIL arrangements permitted by the instrument.
- If you pay a salary to an award-covered employee, include wording about what the salary is intended to cover and implement routine reconciliations to make sure the employee is not worse off compared to award entitlements in practice.
- If an award allows an annualised wage arrangement, follow its record-keeping, notification and reconciliation requirements precisely.
3) Record Time Accurately
- Implement a simple, reliable timesheet or digital clock-in system, including a way to record overtime worked and whether it was approved.
- Keep your rosters compliant with award rules about breaks, minimum engagements and changes. If you’re building or updating rostering processes, it’s worth reviewing the legal requirements for employee rostering that can affect overtime triggers.
- Maintain records of any TOIL agreements and balances if you offer TOIL.
4) Set A Simple Overtime/TOIL Policy
- Explain when overtime is approved, who can authorise it, how it’s recorded, and whether TOIL is permitted under your instrument.
- Be upfront during onboarding so expectations are clear from day one.
5) Calculate And Pay Correctly
- Apply the correct overtime rates and minimum call-outs, and check for different rates for evenings, weekends and public holidays.
- If your award has complex penalty structures, add a monthly or quarterly double-check to your payroll process. Many businesses also use a periodic reconciliation for salaried staff to ensure there’s no underpayment.
- If you’re unsure how rates stack across different days and times, it can help to reference an overtime rates guide and confirm your instrument’s specifics.
6) Get Advice Before Issues Snowball
- If your business has mixed rosters (days, nights, weekends), lots of part-time hours or a blend of salaried and hourly roles, a short review can save headaches later.
- It’s also sensible to check your approach before launch or after a material change (for example, moving to weekend trading). Our team can sanity-check your contracts and systems so you’re set up the right way.
Overtime FAQs (Straight Answers To Common Questions)
Do I Have To Pay Overtime Once Someone Works More Than 38 Hours?
Not automatically. The NES sets 38 hours as the benchmark for full-time employees and requires that additional hours be reasonable. Whether extra hours attract overtime rates depends on the applicable award, enterprise agreement or contract. That said, many awards do convert extra hours to overtime after certain thresholds or outside the span of ordinary hours.
Is A Salary Enough To Cover Overtime?
A salary can cover overtime for an award-covered employee only if, in practice, the salary is at least equal to what the employee would have earned under the award (including overtime, penalties and allowances) for the hours actually worked. Regular reconciliations are the safest approach. Where an award has annualised wage clauses, you must follow those rules.
Can I Make Someone Take TOIL Instead Of Paying Overtime?
No. TOIL must be by agreement and must comply with the rules in the applicable instrument. Many awards require hour-for-hour TOIL, taken within a set period, with payment at overtime rates if it isn’t taken in time. Employees can’t be forced to accept TOIL instead of payment.
Do Casuals Get Overtime?
Often, yes – but the triggers and rates are award-specific. For example, casuals might attract overtime after a certain number of hours per day, or outside the ordinary span of hours. Check the casual section of the relevant award and the rules around casual loading vs. overtime rates. If you engage lots of casuals, this overview of casual overtime rules is a useful starting point.
How Do “Reasonable Additional Hours” Fit In?
Under the NES, employees may be asked to work reasonable additional hours. Whether additional hours are reasonable depends on factors like health and safety, the employee’s personal circumstances, workplace needs and any compensation arrangements. This concept doesn’t replace overtime rules – it operates alongside them. If an award or agreement says overtime rates apply, you must pay them even if the hours were “reasonable.”
What About Breaks Between Shifts And Minimum Rest?
Many awards include minimum breaks and minimum times between shifts, which can affect when overtime starts or whether a higher rate applies. Building those limits into your rostering process reduces the risk of accidental breaches – another reason to have a simple policy and keep accurate records.
Key Takeaways
- If an award, enterprise agreement or employment contract entitles an employee to overtime, not paying it is unlawful – regardless of whether the employee “doesn’t mind” working late.
- The NES sets maximum weekly hours and the concept of reasonable additional hours, but it doesn’t itself create overtime penalty rates; those come from awards, agreements or contracts.
- Salaries and flat rates must still meet award entitlements in practice, including overtime and penalties. Regular reconciliations and clear contract wording reduce risk.
- TOIL is only lawful if allowed by the relevant instrument and the conditions are met (written agreement, hour-for-hour accrual, time limits and records). Otherwise, pay the overtime.
- Good systems – the right Employment Contract, accurate timesheets, compliant rosters and clear policies – are your best defence against underpayments.
- Underpayments can lead to back pay, civil penalties and, for deliberate conduct, potential criminal consequences. It’s simpler and cheaper to get it right upfront.
- If you’re unsure about classifications, rosters or rates, a short review of your approach to overtime laws and rostering requirements can give you certainty.
