Difference Between Full-Time and Part-Time Employment: Employer’s Guide

Hiring your first team member or reshaping your roster is an exciting step. It’s also the point where you’ll need to make a clear call on employment status: full-time or part-time. Getting this right affects how you pay staff, what leave they accrue, when you can roster them, and the rules you must follow under Australian employment law.

In this guide, we break down what counts as full-time and part-time employment in Australia, the practical differences that matter day to day, and the legal obligations you’ll need to meet. You’ll also find tips to help you decide which arrangement suits your business and the key documents to have in place.

What Counts As Full-Time And Part-Time Employment?

Under Australian workplace law, full-time and part-time are both permanent forms of employment (unless a fixed-term arrangement is used). The difference is largely about hours and predictability, but the classification also flows into leave accrual, overtime, penalty rates and how you manage rosters.

Full-Time Employment (The Basics)

• Generally averages 38 hours per week (this may be averaged across a roster period if allowed by the applicable award or agreement).
• Is ongoing and permanent (unless it’s a fixed-term full-time contract).
• Attracts the full suite of National Employment Standards (NES) entitlements, including paid annual leave, paid personal/carer’s leave, public holidays, notice and redundancy where applicable.

Full-time roles suit stable workloads and provide predictability for both you and your employee.

Part-Time Employment (The Basics)

• Works fewer than 38 hours per week, on regular, agreed hours (for example, three set days a week or shorter set shifts each day).
• Is also ongoing and permanent.
• Receives the same NES entitlements as full-time employees on a pro rata basis (for example, annual leave accrues in proportion to ordinary hours).

Part-time roles are ideal when your business needs consistent help, but not full-time hours, or where flexibility is a drawcard for talent (such as parents, students or career changers).

Full-Time vs Part-Time: The Practical Differences

On paper, the distinction seems simple. In practice, it touches nearly every aspect of your workforce management. Here are the areas that typically matter most to employers.

1) Hours, Rostering And Minimums

• Ordinary hours: Full-time is usually 38 per week; part-time is fewer, but regular and agreed. Awards often require a written agreement setting out a part-timer’s ordinary hours and patterns.
• Rostering flexibility: Changing a part-time employee’s agreed hours generally requires genuine agreement and may trigger overtime if exceeded (award-dependent). A full-time employee’s hours are more likely to be varied within the ordinary span set by the award or contract.
• Minimum engagement periods: Many awards set minimum shift lengths (for example, three hours). These minimums commonly apply to part-time staff and can affect how you schedule short shifts.

2) Leave And Other Entitlements

• Accrual: Permanent employees accrue paid annual leave and paid personal/carer’s leave. Part-time staff accrue these on a pro rata basis relative to their ordinary hours.
• Public holidays: Where the day falls on the employee’s usual workday, they are generally entitled to be absent and paid at their base rate. If they work on the public holiday, an award or agreement typically sets penalty rates.
• Paid parental leave, compassionate leave and other NES rights: Apply to both full-time and part-time employees, with pay or accrual proportional where relevant.

3) Overtime, Penalties And TOIL

• Overtime: For full-timers, overtime is typically payable for hours worked beyond ordinary hours or outside the award’s span. For part-timers, many awards require overtime when they work beyond their agreed ordinary hours for the day or week (not just beyond 38). The rules vary, so always check your award when setting rosters and approving extra shifts. A quick refresher on overtime can help you stay compliant.
• Penalty rates: Awards may set higher rates for weekends, public holidays, late nights or early mornings. These usually apply to both full-time and part-time employees.
• Time off in lieu (TOIL): If permitted by the award or agreement, TOIL can be used instead of overtime pay, but it must be properly agreed and recorded.

4) Superannuation And Payroll Settings

• Superannuation (no earnings threshold): The $450-per-month threshold no longer applies. In most cases, employers must pay Superannuation Guarantee for eligible employees regardless of monthly earnings. The Super Guarantee rate is 11.5% from 1 July 2024 (rates can change, so check current requirements).
• Base for super: Super is generally paid on Ordinary Time Earnings (OTE). Ensure your payroll system calculates this correctly for both full-time and part-time staff.
• Tax and reporting: You’ll need to withhold PAYG tax and report via Single Touch Payroll. This article provides general payroll information only; always seek tailored accounting or tax advice for your business.

5) Job Security, Notice And Redundancy

• Security: Both full-time and part-time are permanent employment types, so they provide job security and continuity.
• Notice: If employment ends, you’ll usually need to provide (or pay in lieu of) the correct notice periods under the NES, award or contract.
• Redundancy: Redundancy pay may apply based on service length, headcount and other Fair Work requirements.

Quick Note: How Does Casual Employment Differ?

Casual employment is different from both full-time and part-time because there is no firm advance commitment to ongoing work with a predictable pattern of hours. Casuals usually receive a loading instead of paid leave. If what you really need is predictable, ongoing hours, a permanent (full-time or part-time) arrangement is usually more appropriate and reduces the risk of misclassification.

Deciding Which Arrangement To Offer

There’s no one-size-fits-all answer. The right mix of full-time and part-time depends on your workload, budget and how you want to build your culture.

• Workload predictability: If you consistently need staff for 38 hours a week, a full-time role may be best. If demand peaks across certain days or times, part-time can deliver consistency without overspending on quiet periods.
• Budget and cost control: Both options attract core entitlements, but part-time may give you more flexibility to match labour costs to demand without relying on casuals.
• Attracting talent: Many experienced candidates prefer part-time for family, study or lifestyle reasons. Offering high-quality part-time roles can broaden your hiring pool.
• Growth pathway: You might start a role part-time and expand it as demand grows. If you do, document any change to hours and update the agreement rather than drifting into new patterns informally.

Whichever way you go, set it out clearly in a tailored Employment Contract and keep records up to date as roles evolve.

Legal Obligations, Awards And Payroll

Once you classify a role, you need to make sure your paperwork and day-to-day practices match the legal framework that applies to your business.

Check Your Award (Or Agreement)

Most employees are covered by a modern award that sets minimum pay, ordinary hours, overtime rules, penalty rates and minimum shift lengths for full-time and part-time staff. Ensure you’re across your award’s classification levels and rostering rules. If you’re unsure, get support with Modern Awards or broader award compliance so you can roster and pay correctly from day one.

Contract, Position Description And Onboarding

Your employment agreement should state whether the role is full-time or part-time, ordinary hours and patterns, remuneration, leave entitlements, notice, confidentiality and restraints (if any). Pair the contract with a clear role description and give new hires the legally required onboarding documents.

Super, Tax And Payroll Settings

• Ensure your payroll setup applies super on OTE and captures changes to the Super Guarantee rate on time.
• Withhold PAYG tax and report via Single Touch Payroll.
• Record and approve variations to hours in line with award rules to avoid accidental overtime or underpayments.

Note: Any payroll or tax information in this article is general in nature. Speak with a qualified accountant or tax adviser for advice specific to your circumstances.

Health And Safety Still Applies

Your duty of care under workplace health and safety laws applies to all staff, regardless of hours. Provide training, safe equipment and a process to report hazards. Documenting your expectations in a Staff Handbook makes it easier for everyone to follow the rules.

Documents, Policies And Common Mistakes

Good documentation reduces misunderstandings and keeps you compliant. Here are the essentials most employers will need for full-time and part-time roles.

Essential Documents And Policies

• Employment Contract (Full-Time or Part-Time): Confirms classification, ordinary hours, pay, leave, notice and other core terms. Use a tailored Employment Contract rather than a generic template.
• Workplace Policies / Staff Handbook: Set clear rules around conduct, leave requests, performance, bullying and harassment, technology use and more. A practical starting point is a Staff Handbook.
• Position Description: Outlines duties, hours and reporting lines so expectations are aligned and measurable.
• Payroll & Record-Keeping: Keep accurate records of hours, pay, leave accrual and agreements to vary hours (especially for part-time staff).
• Award/Classification Guide: Maintain an internal reference so managers know the correct rates, penalties and minimums for scheduling and approvals.

Common Mistakes To Avoid

• Misclassifying staff: Labeling an employee as part-time or casual while they work full-time patterns can lead to underpayment claims and penalties.
• Not documenting agreed hours: For part-timers, awards often require an agreement on ordinary hours and how variations are handled. Skipping this step is a frequent cause of overtime disputes.
• Assuming super thresholds still apply: The $450-per-month threshold is gone. Ensure super is paid correctly for eligible part-time employees.
• Overtime blind spots: Many awards trigger overtime for part-timers once they exceed agreed ordinary hours, not only when they pass 38 hours. Revisit your overtime settings and manager approvals.
• Vague or outdated contracts: Outdated clauses, unclear classification or missing terms around hours and flexibility make disputes more likely. When you change hours permanently, update the contract rather than relying on emails.
• Incorrect notice at termination: Make sure you’re providing the right notice periods (or payment in lieu) based on the NES, award and contract.

When Roles Change

If someone moves from full-time to part-time (or vice versa), treat it as a formal variation. Update the written agreement to reflect new ordinary hours and pay. A structured process helps you avoid disputes and stay aligned with award rules on changes to hours and classifications.

If you’re planning a broader reset of terms and rosters, a short internal project to review classifications, awards and contracts can prevent underpayments and streamline scheduling going forward.

Key Takeaways

• Full-time is typically 38 hours per week and part-time is fewer but regular and agreed; both are permanent and attract core NES entitlements, with part-time accruing pro rata.
• The biggest practical differences show up in hours, rostering, overtime triggers, penalty rates and leave accrual. Awards set the ground rules, so check them before you roster.
• Superannuation generally applies regardless of monthly earnings, and the Super Guarantee rate changes over time - configure payroll to pay super on Ordinary Time Earnings.
• Put classification, hours and entitlements in a tailored Employment Contract and support it with clear policies (such as a Staff Handbook) and accurate records.
• Avoid common mistakes like misclassification, failing to document part-time hours, missing overtime rules for part-timers, or using outdated notice and termination settings.
• If you’re unsure about awards, classifications or rosters, get help with Modern Awards or full award compliance support to reduce risk and keep payroll accurate.
