Hiring Part-Time vs Full-Time Employees: Employer’s Legal Guide (Australia)

Bringing someone onto your team is a big step. Whether you’re making your first hire or expanding to support growth, one of the first questions you’ll weigh up is: should this role be part-time or full-time?

Both options can work brilliantly-if you match the arrangement to the role, your budget, and your legal obligations. The flip side is that misunderstanding the rules around hours, entitlements or awards can expose your business to avoidable risk.

In this guide, we’ll unpack what “part-time” and “full-time” really mean under Australian workplace law, highlight the key legal differences, and walk through the documents and compliance steps you’ll need in place. If you’re choosing between part-time vs full-time, this is your practical roadmap to get it right from day one.

What Do Part-Time And Full-Time Mean In Australia?

Let’s start with the foundations. In Australia, the Fair Work Act 2009 and the National Employment Standards (NES), together with any applicable Modern Award or enterprise agreement, set the baseline rules around hours and entitlements.

Full-Time Employment

• Full-time employees usually work a regular pattern of hours across the week (for example, Monday to Friday, 9am–5pm).
• Under the NES, 38 hours per week is the maximum ordinary weekly hours for full-time employees (plus reasonable additional hours), rather than a “minimum” you must roster. For more detail on limits and “reasonable” additional hours, see the guide to maximum hours of work.
• Full-time staff receive the full suite of NES entitlements, such as paid annual leave and paid personal/carer’s leave, notice of termination and redundancy pay (where applicable).
• They’re often your core team members, providing continuity and availability for ongoing operations.

Part-Time Employment

• Part-time employees work fewer than 38 ordinary hours per week, on a regular and ongoing basis.
• They receive the same types of NES entitlements as full-timers, but on a pro rata basis. For example, annual leave accrues proportionately to hours worked; you can read more in this overview of pro rata leave.
• Part-time roles are ideal where your workload is steady but does not require a full 38 hours each week, or where you want to offer flexibility to attract experienced talent.

The correct classification matters. It affects rostering, pay, leave, overtime and how you manage changes over time. If a Modern Award applies, it may also prescribe how you agree hours with part-time staff (for example, minimum engagements or how to vary agreed hours).

Part-Time vs Full-Time: Key Legal Differences

Once you understand the definitions, the main differences come down to how hours are set, how entitlements accrue, and how awards and workplace policies operate in practice.

Hours And Patterns Of Work

• Full-time staff generally work a stable weekly pattern up to the NES maximum of 38 ordinary hours (plus reasonable additional hours).
• Part-time staff work less than 38 hours but on a regular, ongoing basis with agreed hours. Many awards specify how to record and vary those hours, and may set minimum hours for permanent part-time employees per engagement or per week.
• Record the role type (part-time or full-time), ordinary hours and any overtime rules in the employment contract to keep expectations clear.

Pay, Overtime And Penalty Rates

• Both full-time and part-time employees must be paid at least the minimum rate for their classification under any applicable Modern Award or enterprise agreement, plus penalty rates and overtime where applicable.
• Overtime for part-timers often kicks in when they work beyond their agreed ordinary hours, rather than only after 38 hours. Check the particular award to avoid underpayments.
• Superannuation applies to both categories in the same way (more on this below under compliance).

Leave Entitlements

• Full-time employees generally accrue four weeks of paid annual leave per year (additional weeks may apply for shiftworkers under some awards).
• Part-time employees accrue annual leave and paid personal/carer’s leave on a pro rata basis aligned to their ordinary hours. Useful context is in this breakdown of annual leave entitlements for part-time employees.
• Public holidays, parental leave, compassionate leave and other NES entitlements apply to both, subject to usual eligibility rules.

Flexibility And Continuity

• Full-time roles can deliver stability, consistent availability and a deeper investment in onboarding and development.
• Part-time roles provide flexibility and can help you match staffing to demand without committing to a full week of work, which can be especially helpful for seasonal or variable workloads.

Which Option Fits Your Business?

There isn’t a single “right” answer-it depends on the work you need done, your budget, and how you plan to grow. Here are practical questions we encourage employers to consider.

Nature And Volume Of Work

• Is the workload steady and spread across the week, or concentrated on particular days/times?
• Do you need daily coverage or a continuous presence for client or operational needs?
• Could the responsibilities be shared across two part-time roles without creating inefficiencies?

Budget And Resourcing

• While part-time roles can lower wage costs, multiple part-timers for coverage can equal or exceed one full-time salary once you factor training, handovers and rostering complexity.
• If you expect the role to grow, starting part-time with a pathway to full-time can give you (and the employee) flexibility.

Compliance And Risk

• Make sure you can meet award requirements around agreed hours, overtime triggers and record-keeping for whichever option you choose.
• Be clear on notice periods, probation, performance management and how you’ll handle changes to hours if the role evolves.
• If you’re unsure how a specific award applies to your roles, it’s worth checking the rules around classifications, pay rates and rostering before you advertise.

Employment Contracts And Workplace Documents

Once you’ve chosen the role type, lock in a tailored employment agreement and practical workplace policies. Clear documents set expectations and reduce disputes.

Core Terms To Include

• Role And Hours: State whether the role is part-time or full-time, the ordinary hours and pattern (days/times), and how overtime is managed.
• Pay And Super: Include base pay, classification level (if award-covered), penalty rates and allowances where relevant, and superannuation contributions (including when they’re paid). For clarity on what counts towards super, see the overview of ordinary time earnings (OTE).
• Leave: Outline paid leave accrual and approval processes, noting pro rata accrual for part-timers.
• Notice And Termination: Set out probation, notice of termination and grounds for dismissal, consistent with the NES and any applicable award.
• Conduct And Confidentiality: Cover duties, policies, confidentiality, intellectual property, and use of devices and systems.

For a strong starting point, many employers use a tailored Employment Contract for full-time or part-time roles that reflects the specific award rules and your business practices.

Helpful Workplace Policies

• Staff Handbook: Practical rules in one place-code of conduct, leave processes, social media, bullying and harassment, complaints, and more. A structured Staff Handbook Package helps ensure consistency.
• Workplace Policies: Issue policies for WHS, internet and email use, flexible work requests and grievance handling. If you need a template tailored to your operations, consider a Workplace Policy that aligns with your award and risk profile.
• Rostering: If your business uses rosters, ensure processes comply with award rules and local fatigue management standards. This guide to employee rostering requirements is a good sense-check.

Legal Compliance Checklist For Employers

Both part-time and full-time employees are protected by the NES and benefit from many of the same entitlements. Here’s a concise compliance checklist to keep you on track.

1) National Employment Standards (NES)

• The NES sets minimum standards for maximum weekly hours, requests for flexible work, leave, public holidays, notice of termination and redundancy (among others).
• You must provide new employees with the Fair Work Information Statement (and, if casual, the Casual Employment Information Statement).

2) Modern Awards Or Enterprise Agreements

• If a Modern Award applies, it will set minimum pay rates, overtime and penalty rules, allowances, breaks, consultation obligations and dispute resolution processes.
• Confirm the correct award and classification for each role and document it in the employment contract. If you’re unsure, professional advice on Modern Awards is invaluable.

3) Wages, Payroll And Record-Keeping

• Pay according to the relevant minimum rates and ensure payroll systems correctly calculate overtime and penalties for part-time and full-time staff.
• Keep accurate records for hours worked, pay, leave and superannuation. Records must be retained for at least seven years and be readily accessible for inspection.

4) Superannuation

• The former $450-per-month threshold was removed from 1 July 2022. In practice, most adult employees are entitled to Superannuation Guarantee contributions regardless of monthly earnings, subject to limited exceptions set by law.
• Pay super at the legislated SG rate on ordinary time earnings. If you’re reviewing what counts as OTE or how extras are treated, this breakdown of ordinary time earnings and this note on superannuation on bonuses can help you sense-check edge cases.
• Tax and super settings can change-speak with your accountant for tailored advice on PAYG withholding, payroll tax, GST and STP reporting.

5) Workplace Health And Safety (WHS)

• You must provide a safe workplace, identify and manage risks, consult with workers and keep training up to date-regardless of part-time or full-time status.
• WHS duties extend to remote or hybrid work. Practical steps are outlined in this overview of an employer’s duty of care.

6) Anti-Discrimination And Equal Opportunity

• Ensure recruitment, promotion, training and day-to-day management don’t discriminate on protected attributes. Build your policies and decision-making processes around fairness and objective criteria.
• Document flexible work requests and outcomes carefully and be guided by award and NES obligations.

7) Notice Periods, Probation And Ending Employment

• Set a reasonable probation period and document performance expectations early. If you need to end employment, ensure notice and final pay are calculated correctly (including pro rata leave for part-time staff).
• Where a role is award-covered, check any additional consultation obligations that apply before changing hours or duties.

Changing Status Between Part-Time And Full-Time

It’s common for roles to evolve. You can change an employee’s status from part-time to full-time (or vice versa) if you follow the right process and both parties agree.

How To Manage A Status Change

• Discuss the change with the employee, including hours, pay rate, benefits and the proposed start date.
• Put the change in writing as a contract variation or a new contract. Update the classification, agreed hours and any award-specific obligations around varying hours.
• Adjust payroll settings, leave accruals and roster systems from the effective date.

If you’re moving from full-time to part-time (or the reverse), check out this practical guide to changing an employee’s status so nothing slips through the cracks.

What About Casual Conversion?

Casual conversion rules are a separate process under the Fair Work Act and relevant awards. If you employ casuals who become eligible to convert to permanent employment, there are specific timelines and notice requirements you’ll need to follow. Keep an eye on eligibility and be ready with the right permanent contract if conversion occurs.

Next Steps For Employers

Choosing between part-time and full-time is as much a strategic decision as it is a legal one. The best approach is to map the role, check the award, put a clear contract in place and set up simple systems for rostering, payroll and leave. Small steps now save big headaches later.

Key Takeaways

• Full-time and part-time are both ongoing employment types; the key difference is the regular hours worked and how entitlements accrue.
• Under the NES, 38 hours is the maximum ordinary weekly hours for full-time employees (plus reasonable additional hours), not a minimum roster requirement.
• Part-time employees receive the same NES entitlements on a pro rata basis; awards often include specific rules on agreed hours, overtime triggers and minimum engagements.
• Use a tailored Employment Contract and practical policies (like a Staff Handbook) to set expectations and reduce disputes.
• Stay compliant with the NES, any applicable Modern Award, superannuation and WHS duties; keep clear records for hours, pay, leave and super.
• Tax and super settings change over time-work with your accountant on PAYG, super and payroll systems, and seek legal advice if you’re unsure how award rules apply to your roles.
• If you change an employee’s status, document it in writing and align contracts, rosters and payroll from the effective date; this guide to changing status is a useful checklist.
