Casual vs Permanent Employment in Australia: What Every Small Business Owner Needs to Know

Casual and permanent employment in Australia have different costs, obligations, and risks. Choosing the wrong one, or misclassifying an employee, can create significant liability. Here is what the difference actually means for your business.

One of the most common questions we get from small business owners is whether to hire someone as casual or permanent. There is no single right answer, but there are clear guidelines about which arrangement suits which situation.

Getting this wrong is not just an administrative issue. Misclassifying a permanent employee as casual, or running a casual arrangement that starts to look like permanent employment, creates real legal and financial risk.

What is the difference?

What makes someone a casual employee?

Under the Fair Work Act 2009 (Cth), a person is a casual employee if they are offered a job with no firm advance commitment to ongoing work, and they accept on that basis. The key word is “firm advance commitment.” If you hire someone and both parties understand there will be regular, ongoing work, that person may not actually be a casual employee regardless of what the contract says. (Fair Work Ombudsman — Casual Employees)

This is where many small businesses get into trouble. They hire someone as casual because they want flexibility, but then that person works the same shifts every week for two years. At that point, the casual classification is questionable.

The casual conversion rules

Since 2021 and updated in 2024, casual employees who have worked regular patterns for 12 months have enhanced rights to request conversion to permanent employment. The employer must respond to that request and, in most cases, cannot simply refuse without a genuine reason based on the operational needs of the business.

From 26 August 2024, the definition of casual employment was updated under the Fair Work Legislation Amendment (Closing Loopholes No. 2) Act 2024. Employers now need to assess the real nature of the working arrangement, not just what the contract says. (Fair Work Ombudsman — Changes to Casual Employment 2024)

“The casual loading is meant to compensate for the lack of leave entitlements. But if a casual ends up working regular hours long-term, they may actually cost more than a permanent employee once you factor in the loading and the conversion risk.”

When does casual make sense?

Casual employment is appropriate when:

• The work is genuinely irregular and unpredictable
• You need cover for peak periods or events
• You are trying out a new role before committing to a permanent hire
• The person genuinely prefers the flexibility of casual work

When does permanent make more sense?

Permanent employment is usually better when:

• You need someone to work regular, predictable hours
• The role is integral to the business operation
• You want the person invested in the business long-term
• The casual loading would cost more over time than leave entitlements

What about part-time permanent?

Part-time permanent employees work less than 38 hours per week but have the same entitlements as full-time employees, pro-rated. This is often the better option for roles that need regular hours but not full-time commitment. A part-time permanent arrangement gives both employer and employee more certainty than ongoing casual work.

What should I do if I am not sure?

Review your current casual arrangements and ask honestly: are these people working regular patterns? Have they been with you for more than 12 months? If the answer is yes to both, it is worth getting advice on whether the classification is appropriate and whether a conversion conversation is needed.
