Minimum Hours For Full-Time Employment In Australia: Employer’s Guide

Hiring full-time staff is a big step for any growing business. It gives you stability, helps with planning, and builds a committed team. But the rules around “full-time hours” can be confusing - especially with flexible rosters, different awards, and evolving workplace expectations.

In Australia, the Fair Work system sets a clear framework for hours and entitlements. Getting these settings right isn’t just a compliance exercise. It’s about setting expectations, paying correctly, and avoiding disputes before they start.

In this guide, we’ll unpack what full-time really means, how maximum and ordinary hours work, when fewer than 38 hours may still be full-time, and the practical steps to set up compliant contracts and rosters.

What Counts As Full-Time Work In Australia?

There isn’t a single definition of “full-time” that fits every workplace. However, under the National Employment Standards (NES) in the Fair Work Act, full-time employment is generally understood as an employee who ordinarily works around 38 hours per week (or the hours considered full-time under the applicable award or enterprise agreement).

Two key points sit behind that general understanding:

• The NES sets a maximum of 38 hours per week for full-time employees, plus reasonable additional hours - it is not a minimum you must roster every week.
• What constitutes the “ordinary hours” of a full-time role often comes from a modern award or an enterprise agreement. Many instruments set full-time ordinary hours at 38 per week, but some specify 36, 37 or 37.5.

So, when you’re deciding what “full-time” means in your business, start by checking the relevant award or agreement (if one applies), then reflect those hours in a well-drafted Employment Contract.

Maximum Weekly Hours Vs Ordinary Hours: What’s The Difference?

This distinction trips up a lot of employers. It helps to separate the legal caps from the roster you set day to day.

Maximum Weekly Hours (NES rule)

• Full-time employees have a cap of 38 hours per week plus reasonable additional hours.
• Paid leave and public holidays are generally treated as hours worked for the purpose of this cap.
• Whether extra hours are “reasonable” depends on factors like health and safety risks, employee circumstances, the needs of the workplace, and how much notice you gave.

For an overview of your obligations here, it’s worth reviewing maximum weekly hours and when additional hours may be reasonable under the NES. We’ve unpacked these rules in our guide to maximum hours of work per week.

Ordinary Hours (award/contract rule)

• “Ordinary hours” are the hours an employee is rostered to work without overtime penalties.
• These are set by an award/enterprise agreement or by contract if there’s no applicable instrument.
• Ordinary hours can be arranged across different patterns - Monday to Friday, shifts, weekends - depending on the instrument and your business needs.

Once you understand your ordinary hours, you can identify when overtime rates or time off in lieu (TOIL) might apply.

Can A Full-Time Employee Work Fewer Than 38 Hours?

Short answer: yes, in some cases. The NES “38-hour week” is a maximum (with reasonable additional hours), not a minimum you must hit every week.

Whether a full-time employee can regularly work fewer than 38 hours without changing their employment status depends on the instrument and the contract.

When fewer hours can still be full-time

• Award or agreement defines full-time below 38: Some awards set full-time at 36, 37 or 37.5 hours a week. If that’s your award, those are the full-time ordinary hours.
• Averaging arrangements: Ordinary hours may be averaged across a period (for example, 38 hours over 4 weeks or up to 26 weeks if permitted). In some weeks an employee may work fewer than 38 hours, and more in others, while remaining full-time overall.

When fewer hours may change status

• Permanent reduction in ordinary hours: If you and the employee agree to a lasting reduction in their regular weekly ordinary hours below what the award or agreement defines as full-time, the role may become part-time.
• Contract and instrument drive the outcome: Labels don’t override substance. If the pattern and contracted ordinary hours are part-time, calling it “full-time” won’t make it so.

As a rule of thumb, set clear ordinary hours in the contract that align with the applicable instrument. If you need to make a lasting change, follow a proper consultation and variation process. We’ve covered how to do that in our guide to changing employment contracts.

Is 30 hours full-time?

Usually not. Thirty hours per week will generally be part-time unless your award or agreement expressly defines full-time at that level (rare) or your ordinary hours are averaged in a way that still amounts to full-time across the averaging period.

Setting, Averaging And Paying For Full-Time Hours

Once you know whether an award or agreement applies, you can set an hours framework that works for your operations and complies with the law.

Common ways to structure full-time hours

• Fixed daily hours: For example, 7.6 hours per day across 5 days to total 38 ordinary hours.
• Shift work: Rosters may span evenings, nights or weekends, with ordinary hours and penalties set by the award.
• Averaging: The NES allows averaging of ordinary hours over up to 26 weeks if agreed in writing and permitted by the instrument. This helps you manage seasonal or project-based fluctuations.

Additional hours, overtime and TOIL

• Reasonable additional hours can be requested beyond ordinary hours, subject to the NES reasonableness test.
• Overtime often kicks in when hours go beyond ordinary hours or outside the spread of hours in the award. Pay the correct overtime rate or provide time off in lieu if the instrument allows it and you follow the required process.
• Make sure you understand when overtime laws apply, how to approve it, and how to record it accurately for payroll and audit trails.

Public holidays and leave

• Paid leave and public holidays are generally treated as hours worked for maximum weekly hours and are factored into leave accruals and pay calculations under the instrument and the NES.
• They don’t “top up” a minimum weekly requirement - instead, they maintain ordinary pay and service during the absence.

Breaks and health and safety

• Most awards specify paid and unpaid breaks (e.g. rest and meal breaks). Ensure rosters and timekeeping align with those rules.
• If you’re unsure which rules cover your workplace, it’s helpful to review your obligations around employee meal breaks and rest periods in your industry.

Contracts, Awards And Day‑To‑Day Compliance

The best way to prevent confusion about hours is to spell out the details in your employment documents and apply them consistently.

What to include in your Employment Contract

• Employment type: Confirm the role is full-time and whether an award or agreement applies.
• Ordinary hours and pattern: Set the weekly ordinary hours, days of the week, and any roster or averaging arrangements.
• Additional hours: Note that reasonable additional hours may be required and how these will be managed (approval, overtime, or TOIL per the instrument).
• Pay and loadings: State the base rate and any penalties or allowances per the instrument.
• Breaks: Reference applicable break entitlements.
• Leave entitlements: Confirm NES entitlements and any industry-specific extras.

Having a tailored Employment Contract that mirrors your actual roster practices and award conditions is essential.

Policies and process

• Put in place clear workplace policies covering timekeeping, breaks, overtime approval, and WHS. Train managers to follow them consistently.
• Keep accurate records of hours worked, overtime approvals, leave taken and breaks. This protects you if a dispute arises.
• Use rosters that align with the spread of hours in the instrument, and provide reasonable notice of changes where required.

Pay correctly, every time

• Pay at least the award or agreement minimum for the classification, including penalties and overtime where applicable.
• Review rates after each annual wage review or relevant instrument update.
• Where your business is award-free, ensure you still meet the national minimum wage and the NES.

Finding the right award

If you’re unsure which award applies, look at the duties, industry, and position level - many roles are covered by large industry awards (e.g. retail, hospitality, health). Once confirmed, align your contracts and rosters to that instrument’s hours, penalties and breaks.

Changing hours or status

• If you need to permanently reduce or reorganise hours, consult with the employee and document the change. A written variation is the safest route and should keep the instrument’s rules intact.
• Major changes to hours or days may trigger consultation obligations, and in some cases, redundancy or redeployment options. Follow a fair, documented process. If you’re navigating change, our guide to changing employment contracts explains what a compliant variation looks like.

Key Takeaways

• The NES sets a maximum of 38 hours per week for full-time employees, plus reasonable additional hours - it’s not a mandatory minimum you must roster every week.
• “Full-time” ordinary hours are set by the relevant award, enterprise agreement or contract. Many are 38 hours, but some are 36–37.5, and averaging is often allowed.
• An employee can sometimes work fewer than 38 hours and remain full-time, particularly where the instrument defines full-time below 38 or ordinary hours are averaged over a period.
• Overtime or TOIL may apply when hours go beyond ordinary hours or outside the spread of hours - understand when overtime laws and TOIL apply for your award.
• Protect your business with clear documents: a tailored Employment Contract, practical workplace policies, accurate time records, and rosters aligned to the instrument.
• When you need to change hours or status, consult and document the variation properly to stay compliant and avoid disputes.
