Managing Employee Probation Periods: A Guide For Australian Employers

Bringing a new team member on board is an exciting step for any business. It’s also a period where you’re assessing fit, clarifying expectations, and building trust. That’s exactly what a probation period is designed for - a short window at the start of employment where both parties can make sure the role is working as intended.

Handled well, probation helps you onboard effectively, address issues early, and make confident decisions. Handled poorly, it can lead to confusion, low morale, or legal risk. In Australia, there are clear rules around notice, protections, and eligibility for claims - and a few myths worth clearing up.

In this guide, we’ll walk through what probation really means under Australian law, how long it should run, what rights apply to both sides, and a practical step-by-step process you can use. We’ll also highlight common mistakes to avoid so you can run a fair, transparent, and compliant process from day one.

What Is A Probation Period In Australia?

A probation period is a clause in an employment contract that sets a defined timeframe at the beginning of employment (commonly three to six months). During this time you’re confirming whether the role, the work, and the team fit are right - and the employee is doing the same.

Probation isn’t a separate legal status created by legislation. It’s a contractual tool. Employees on probation still receive their usual minimum entitlements (for example, base pay and leave accrual for eligible employees) and are protected from unlawful conduct such as discrimination or adverse action from day one.

While probation is not required by law, most employers include it in the Employment Contract to set clear expectations, outline notice arrangements, and describe how performance will be assessed.

How Long Should Probation Last (And What It Does - And Doesn’t - Change)?

There’s no legislated minimum or maximum length for probation in Australia. In practice, three to six months is common because it gives enough time to assess onboarding, performance, and culture fit.

It’s important to separate two concepts that often get mixed up:

• Probation length is a contractual period you set in the Employment Contract.
• Unfair dismissal eligibility comes from the Fair Work Act based on length of service, not the probation clause.

As a general rule, employees become eligible to apply for unfair dismissal after six months of continuous service (or after 12 months if you’re a small business with fewer than 15 employees). Extending a probation clause beyond these timeframes does not delay eligibility for unfair dismissal - the legal test looks at service, not what your contract calls the period.

This means you can run a longer probation if your contract allows, but once the service threshold is passed, unfair dismissal protections may apply (subject to other requirements like minimum employment period and earnings cap). Plan your assessments and decision points accordingly.

Rights, Notice And Termination During Probation

Probation offers flexibility, but it doesn’t remove basic workplace rights. Here’s how the key rules work in Australia.

Minimum entitlements during probation

• Leave and pay: Full-time and part-time employees accrue annual leave and personal/carer’s leave as normal during probation. Casuals don’t accrue paid leave but receive a casual loading instead.
• General protections: From day one, employees are protected from unlawful treatment (for example, adverse action because they exercised a workplace right, or discrimination based on protected attributes).
• Awards/agreements: Any applicable modern award or enterprise agreement continues to apply during probation (for example, classification, minimum pay, and consultation obligations).

Notice periods during probation

• Permanent employees: Under the National Employment Standards (NES), the minimum notice for employees with less than one year of service is one week (this can be higher if your contract, award or enterprise agreement says so).
• Casual employees: The NES notice requirement does not apply to casuals. Check your contract and any applicable award in case a longer period is required.
• Payment in lieu: You can give notice or pay it out. If you pay it out, follow a lawful process and calculate entitlements accurately - see this guide to payment in lieu of notice.
• Serious misconduct: You can generally dismiss without notice for serious misconduct (for example, theft or fraud). Make sure you’ve investigated properly and have a sound basis for the decision.

Ending employment during probation

You can lawfully end employment during probation if you provide the required notice (or pay in lieu), follow any process in the contract or applicable instrument, and avoid unlawful reasons. There is no general legal requirement to give a written reason, but it’s best practice to document performance concerns and communicate your decision clearly and respectfully. If you’re unsure, refer to this overview on termination during probation.

Remember, unfair dismissal eligibility is about the employee’s length of service. Most employees cannot bring an unfair dismissal claim until they’ve reached the minimum employment period (six or 12 months), but “general protections” and discrimination claims can be raised from day one. For small businesses, the Small Business Fair Dismissal Code may apply - but you still need a reasonable basis for your decision and fair process.

Can employees take leave during probation?

Yes. Permanent employees accrue and can take leave in line with your policies and the NES. If a medical issue arises, you may request reasonable evidence and, in some circumstances, medical clearance to return to work. There’s also a helpful guide on taking leave during probation if you need to set expectations with new starters.

A Practical, Step-By-Step Probation Process

Great probation management is more than a clause in a contract. Use a simple framework that’s fair, consistent and documented.

1) Set it up clearly in the Employment Contract

• Specify the probation length (for example, “six months from the start date”).
• Confirm the notice period during probation and whether payment in lieu may be made.
• Describe high-level expectations and that performance will be assessed during probation.
• Include whether the employer may extend probation and the process for doing so.

If your template is due for a refresh, consider updating your Employment Contract so your probation, notice and process clauses are aligned with current law and your practices.

2) Onboard with structure and support

• Provide a role overview, success measures, and key training in week one.
• Share relevant workplace policies (for example, conduct, leave, and safety).
• Assign a buddy or manager check-in schedule to set the employee up for success.

3) Hold regular check-ins and document feedback

• Run short check-ins (for example, at weeks 2–3, then monthly) to discuss what’s going well and where support is needed.
• Record action items and timelines so expectations are crystal clear.
• Where issues persist, move to a more formal conversation and keep notes. If concerns are serious, you may use a structured process such as a performance meeting or, where appropriate, a show cause letter.

4) Make a timely decision before the probation end date

• Confirm ongoing employment: Send a short confirmation letter or email.
• Extend probation: Only if your contract allows and you notify the employee before the original end date. Make clear the new end date and what needs to improve.
• End employment: Provide the correct notice (or pay in lieu), process final pay correctly, and communicate respectfully. You don’t have to provide a detailed written reason, but keep your records in order.

Tip: Put reminders in your HR system at least 2–4 weeks before the probation end date so you have time to assess, decide, and notify.

5) If concerns escalate, follow a fair process

Where conduct or performance falls well short, pause and ensure your process is sound. Gather facts, give the employee a chance to respond, and consider any relevant mitigating circumstances. If you need a pack of ready-to-use documents to support a compliant process, Sprintlaw offers an Employee Termination Documents Suite to help you move quickly and carefully.

Extending probation: proceed carefully

• Check the clause in the Employment Contract first - if it doesn’t permit extension, obtain written agreement via a variation before the original end date.
• Explain the reason for extending and the objectives for the new period.
• Be mindful that extending probation does not change the legal test for unfair dismissal eligibility once the employee passes the required service period.

Common Pitfalls And How To Avoid Them

• Mixing up probation with unfair dismissal eligibility: Eligibility is based on service (six or 12 months), not the label in your contract.
• Letting the date slip: If you plan to extend or end employment, decide and notify before the probation end date.
• Extending without a right to do so: If your contract doesn’t allow extension, get a signed variation in place first.
• No documentation: Keep simple notes of check-ins, action items and decisions. They help drive improvement and protect your business.
• Overstating obligations: You don’t have to give a written reason by default, but a clear, respectful explanation is good practice.
• Ignoring different employee types: Notice rules differ for casuals versus permanent staff, and serious misconduct is treated differently. If you’re unsure, get advice before acting.
• Missing entitlements at exit: Pay the right notice or payment in lieu, and include accrued entitlements in the final pay. If you need a refresher on mechanics, see the guidance on payment in lieu of notice.

Promotions and internal moves

It’s common to set a probation period for a promoted or transferred employee to assess suitability for the new role. Make sure you confirm this in writing (for example, via a variation letter) and remember that service for unfair dismissal purposes continues - a “new” probation period doesn’t reset the legal clock.

Leave and medical evidence

Employees can take leave during probation in line with the NES and your policies. Be consistent about requesting evidence and consider whether medical clearance is reasonable in the circumstances. For practical guidance around expectations, refer to this overview on leave during probation.

When to get help

If you’re dealing with conduct concerns, potential serious misconduct, or a sensitive termination, it’s worth speaking with an employment lawyer early. A short consult can help you assess risk, choose the right process and prepare the right documents, including a probation termination notice or a show cause letter where needed.

Key Takeaways

• Probation is a contractual period to assess fit; employees still receive core workplace rights and protections from day one.
• Three to six months is common. Unfair dismissal eligibility is based on service (six months, or 12 months for small businesses) - not the length of your probation clause.
• During probation, follow the correct notice rules, or pay in lieu if ending immediately, and avoid unlawful reasons for termination.
• Run a structured process: a clear Employment Contract, regular check-ins, documented feedback, and timely decisions before the probation end date.
• Only extend probation if your contract allows and you notify the employee in writing before the original end date; note this does not delay unfair dismissal eligibility once service thresholds are met.
• Keep records and use fit-for-purpose documents (for example, a show cause letter or termination pack) to support a fair and lawful process.
