Employee Probation: Best Practices For Australian Employers

Bringing on a new team member is exciting – and a little uncertain. A probation period gives you both time to check that the role, performance and culture fit are right.

Handled well, probation can boost retention, improve performance and reduce legal risk. The key is to set clear expectations, follow a fair process and understand what the law does (and doesn’t) allow during this time.

In this guide, we cover what probation means in Australia, how long it should run, how to structure your process, the legal rules that still apply, and the key documents you’ll need to stay compliant and confident.

What Is Employee Probation?

A probation period is a defined timeframe at the start of employment where both you and the employee assess suitability.

It’s not a separate type of employment. A “probationary employee” is simply a new employee whose contract includes a probation clause. They still receive the same baseline protections as other employees, including entitlements for permanent staff (like annual leave and personal/carer’s leave) accruing from day one.

Think of probation as structured onboarding with checkpoints. You’re testing real-world performance, behaviour, communication, reliability and cultural fit – not just what was on the CV.

How Long Should Probation Last In Australia?

Typical Probation Lengths

Most Australian employers use three to six months. That’s usually long enough to set goals, provide feedback, and make a fair, evidence-based decision.

Probation vs Minimum Employment Period (Unfair Dismissal)

This is where many employers get tripped up. The label “probation” doesn’t change when an employee can access unfair dismissal under the Fair Work Act.

• For businesses with fewer than 15 employees, the minimum employment period is 12 months.
• For businesses with 15 or more employees, it’s 6 months.

Extending a probation period beyond these timeframes does not delay unfair dismissal eligibility. In other words, if a large employer runs a nine-month probation, the employee may still be able to bring an unfair dismissal claim after six months of service.

When deciding if a dismissal was harsh, unjust or unreasonable, the Fair Work Commission considers several factors set out in section 387 of the Fair Work Act – regardless of what you called the period.

Setting Up A Compliant Probation Process

Clarity from day one is the best risk management. A simple, structured approach helps your new starter succeed and gives you a fair basis for any decision you make.

1) Put It In The Contract

Include a clear probation clause in the employee’s contract. Specify the length, how performance will be assessed, whether it can be extended, and what happens at the end. Use a tailored Employment Contract suited to the role (full-time, part-time or casual) and your industry.

2) Define Expectations And Milestones

Set measurable goals for the probation period. Share position descriptions, KPIs and how you’ll measure results (e.g. quality metrics, client feedback, teamwork, values).

Back this up with practical policies. A clear Workplace Policy framework (covering conduct, performance, leave, WHS and IT use) helps everyone understand the standards.

3) Plan Check-Ins

Schedule structured meetings (for example, at weeks 2, 6 and 10 of a 12‑week period). Keep notes of what’s going well and what needs improvement, and agree on action items with timeframes.

4) Address Issues Early

If concerns emerge, don’t wait for the last week. Explain the gap, provide support and set a short improvement plan. This is fair to the employee and gives you evidence of a reasonable process.

5) Decide Before The End Date

Hold a final review before the probation end date and communicate your decision promptly in writing: confirmation, a permitted extension (if your contract allows it), or termination with the correct notice.

Managing Performance And Making Decisions

Probation should feel like a collaborative trial, not a one-sided test. A consistent process makes decisions easier and lowers the risk of disputes.

Feedback That Works

• Be specific and timely: describe the behaviour or outcome, the impact and the expected standard.
• Offer support: training, shadowing, clearer priorities or revised KPIs if needed.
• Document briefly: dot points after each check-in are enough – keep them factual.

Extending Probation

You can only extend probation if the contract allows it. Confirm any extension in writing, with a new end date and clear goals. Remember, an extension does not change the minimum employment period for unfair dismissal eligibility.

Confirming Ongoing Employment

If probation is successful, send a short confirmation letter or email. Reiterate the role title, employment type and that the original contract terms continue unchanged.

If You’re Ending Employment

Sometimes it’s not the right fit. If you decide to end employment during probation:

• Meet with the employee and explain your decision respectfully, with brief reasons focused on performance or role requirements.
• Give the correct notice (or pay in lieu) based on the contract, any applicable award or the NES. A quick refresher on employment notice periods can help.
• Where appropriate, consider payment in lieu of notice to finalise quickly and reduce disruption.
• Pay all entitlements owing up to the termination date and issue required documents (e.g. payslip, final pay details).
• Keep a short record of the process you followed and the reasons for your decision.

For a deeper walkthrough of process and risks, see terminating employment during probation. If issues have been ongoing, a structured performance management process provides a clear framework.

Legal Rules That Still Apply During Probation

Probation is not a “no rules” period. Most core employment laws apply from day one.

National Employment Standards (NES)

Permanent employees accrue annual leave and personal/carer’s leave during probation. Maximum weekly hours, public holiday rules and other NES entitlements apply in the usual way.

Notice Of Termination

Minimum notice requirements under the NES, any applicable award or your contract still apply during probation (unless the employee is casual and no notice is required under the relevant instrument). Make sure the notice you give is at least what the law or instrument requires.

Unfair Dismissal, General Protections And Discrimination

Whether an employee can claim unfair dismissal depends on their length of service and the size of your business, not on whether they are “on probation”. Extending probation doesn’t delay this access.

Separately, employees are protected from unlawful discrimination and adverse action (general protections) from day one. Decisions must not be based on protected attributes, workplace rights or industrial activity.

Work Health And Safety (WHS)

You owe the same WHS duties to probationary staff as to any other worker. Provide a safe work environment, training, supervision and appropriate equipment.

Awards, Enterprise Agreements And Policies

Industry instruments or internal policies may include specific rules around probation and termination. Always check the applicable award or agreement and ensure your internal processes line up with what you’ve promised employees.

Key Documents For Probationary Employment

Good documents keep your process fair, consistent and legally sound. At a minimum, consider:

• Employment Contract: Sets the probation length, assessment method, notice requirements and whether an extension is possible. Use a role‑appropriate Employment Contract for full-time, part-time or casual staff.
• Workplace Policies / Staff Handbook: Communicate standards around conduct, leave, performance, WHS and IT use in a clear Workplace Policy suite.
• Probation Review Template: A simple form to record feedback, goals and outcomes at each checkpoint and the final decision.
• Confirmation Letter: Confirms successful completion and ongoing employment.
• Termination Letter: Documents notice (or payment in lieu), the final date and return-of-property requirements; an employee termination documents suite helps keep this consistent.

Keep everything short and practical. The aim is clarity, not bureaucracy.

Common Mistakes To Avoid

• Equating “probation” with “no obligations”: NES entitlements, minimum notice (where applicable), WHS and anti‑discrimination laws still apply.
• Letting issues slide: If you wait until the final week to raise concerns, you miss the chance to support improvement and increase your risk profile.
• Using an extension to “reset” rights: Extending probation doesn’t change unfair dismissal eligibility based on the minimum employment period.
• Unclear documents: Vague or missing clauses in the contract lead to confusion. Make sure your probation clause is precise.
• Poor note-keeping: A few dot points after each check‑in can make all the difference if a decision is later questioned.
• Inconsistent treatment: Apply the same process across comparable roles to reduce claims of unfairness or discrimination.

Key Takeaways

• Probation is a structured assessment period – not a separate legal status – and core laws still apply from day one.
• Choose a practical length (often 3–6 months), but remember probation length doesn’t change unfair dismissal eligibility under the minimum employment period.
• Set clear goals, hold scheduled check‑ins, and address issues early with support and brief documentation.
• Decide before the end date and confirm the outcome in writing: confirmation, a permitted extension, or termination with correct notice or pay in lieu.
• Use strong foundations – an Employment Contract, policies and simple review templates – to keep your process fair and consistent.
• If you need to end employment, follow a reasonable process and ensure the right notice; structured support like a probation termination guide can minimise risk.
