Quick Summary
- Casual employees have no guaranteed hours and receive a 25% casual loading instead of paid leave entitlements.
- Part-time employees have guaranteed regular hours and receive pro-rata paid leave, sick leave, and other NES entitlements.
- Casual employees can convert to permanent employment after 12 months of regular hours under NES section 66A.
- Misclassifying an employee as casual when they work regular hours can trigger back-pay claims for unpaid entitlements.
The difference between casual and part-time employment in Australia comes down to three things: guaranteed hours, paid leave entitlements, and job security. Casual employees have no guaranteed hours, receive a 25% casual loading instead of paid leave, and can be offered work as needed. Part-time employees have guaranteed regular hours set out in a written agreement, receive pro-rata National Employment Standards (NES) entitlements including paid annual leave and personal leave, and have ongoing job security. Both types are covered by the Fair Work Act 2009 and any applicable Modern Award.
What Is Casual Employment?
A casual employee is engaged without a firm advance commitment to ongoing work or regular hours. The employer is not obligated to offer work, and the employee is not obligated to accept it. In exchange for this flexibility, casual employees receive a 25% loading on top of their base hourly rate, which compensates for the absence of paid annual leave, personal leave, public holidays, and notice of termination.
Key features of casual employment include:
- No guaranteed hours of work per week or fortnight
- 25% casual loading paid on top of the base rate
- No paid annual leave or paid personal/carer’s leave
- Flexible rostering — shifts can change week to week
- Eligible for casual conversion after 12 months of regular hours under NES section 66A
Employers must provide every new casual employee with a Casual Employment Information Statement from the Fair Work Ombudsman before or as soon as practicable after they start. A written casual employment agreement should also be in place setting out the casual nature of the role, the loading, and the applicable Award.
What Is Part-Time Employment?
A part-time employee works regular, guaranteed hours each week — fewer than 38 hours — set out in a written employment agreement. They receive the same NES entitlements as full-time employees but on a pro-rata basis, calculated according to their agreed weekly hours.
Key features of part-time employment include:
- Guaranteed regular hours specified in the employment agreement
- Pro-rata paid annual leave (4 weeks per year)
- Pro-rata paid personal/carer’s leave (10 days per year)
- Paid public holidays that fall on a normal work day
- Notice of termination and redundancy pay if eligible
Employers should use a written part-time employment agreement template that specifies the guaranteed hours, days of work, and applicable Award. Following HR best practice ensures compliance and reduces the risk of disputes.
⚠️ Misclassification Risk
If a casual employee works regular, predictable hours on an ongoing basis, they may be deemed a permanent employee — exposing your business to back-pay claims for unpaid leave entitlements. Review casual arrangements at least every 12 months.

Casual Conversion: When Does a Casual Become Permanent?
Under NES section 66A, casual employees who have worked for the same employer for at least 12 months, and whose hours have followed a regular pattern that could continue as a permanent arrangement, have the right to request casual conversion. The employer must respond in writing within 21 days and can only refuse on reasonable business grounds — such as expecting a significant change in hours within the next 12 months or the role no longer existing.
Some Modern Awards include additional casual conversion provisions with shorter qualifying periods (e.g., 6 months). Employers must notify eligible casual employees in writing of their conversion rights, and failing to do so can result in penalties. Regular employment contract reviews help ensure casual arrangements are genuinely casual and not de facto permanent arrangements.
Choosing Between Casual and Part-Time for Your Business
Casual employment suits roles with genuinely unpredictable or irregular hours — such as hospitality peaks, retail seasonal surges, or on-call coverage. Part-time employment suits roles with predictable, regular hours where the business needs ongoing coverage — such as administration, regular shifts, or fixed weekly requirements.
The critical risk for employers is treating what is effectively a permanent arrangement as casual. If an employee works the same rostered hours every week for months or years, a Fair Work inspector or the Fair Work Commission will likely find they are a permanent employee — regardless of what the written agreement says. This can trigger back-pay claims for unpaid leave entitlements going back years, plus potential penalties for non-compliance.
If your business needs flexible staffing, ensure the hours are genuinely irregular. If your casuals work the same shifts every week, convert them to part-time to protect both the employee and your business.
Frequently Asked Questions
The main difference is job security and entitlements. Casual employees have no guaranteed hours, receive a 25% casual loading on top of their base rate, and do not receive paid annual leave or personal leave. Part-time employees have guaranteed regular hours set out in writing, receive pro-rata paid annual leave, personal leave, and other National Employment Standards (NES) entitlements, and do not receive casual loading. Both types are covered by the Fair Work Act 2009 and any applicable Modern Award.
Casual employees receive a 25% casual loading on top of their base hourly rate, which compensates for the lack of paid leave entitlements. For a single hour worked, a casual may earn more per hour. However, part-time employees receive paid annual leave (4 weeks pro-rata), paid personal leave (10 days pro-rata), and paid public holidays — which casuals do not. Over a full year, total remuneration can be comparable, but part-time employees have greater income security through guaranteed hours and paid leave.
Yes. Under the National Employment Standards (NES section 66A), casual employees who have been employed for at least 12 months and have worked a regular pattern of hours that could continue as a permanent arrangement have the right to request conversion to permanent employment. Employers must respond in writing within 21 days and can only refuse on reasonable business grounds. Some Modern Awards also include additional casual conversion clauses with shorter qualifying periods.
Part-time employees receive pro-rata National Employment Standards entitlements including paid annual leave (4 weeks per year, pro-rata), paid personal/carer’s leave (10 days per year, pro-rata), paid compassionate leave, paid public holidays, notice of termination, and redundancy pay if applicable. Casual employees do not receive paid leave but instead receive a 25% casual loading. Both types are entitled to superannuation (if earning more than $450 per month) and unpaid carer’s leave.
There is no specific hour threshold that automatically converts a casual to permanent. The key test under NES section 66A is whether the casual has worked a regular pattern of hours for at least 12 months that could continue without significant change as a permanent arrangement. If an employee works 38 hours every week on a fixed roster for over a year, they likely qualify for casual conversion regardless of the total hours — it is the regularity and ongoing nature that matters.
Yes. The Fair Work Act 2009 requires all employers to provide every new employee (casual, part-time, or full-time) with a written agreement or letter of engagement before or as soon as practicable after they start. For casual employees, a Casual Employment Information Statement must also be provided. The agreement should specify employment type, hours of work (for part-time), rate of pay, casual loading (for casuals), and any applicable Modern Award. You can download free employment agreement templates from Fair Work Centre.
The standard casual loading is 25% on top of the base rate of pay, as set out under most Modern Awards and the National Employment Standards. This loading compensates casual employees for not receiving paid annual leave, paid personal leave, paid public holidays, and notice of termination. Some Awards specify different loading rates, so employers must check the relevant Award for their industry. The 25% loading should be clearly shown separately on pay slips.
Misclassifying a part-time employee as casual can lead to significant financial liability. The employer may be required to back-pay all unpaid annual leave, personal leave, public holiday pay, and other NES entitlements for the entire period of misclassification. The employee may also file a general protections claim or an unfair dismissal claim if terminated. Fair Work inspectors can impose civil penalties of up to $93,900 per contravention for a company. Employers should audit their casual workforce regularly to ensure classification is correct.
