Probation Periods in Australia: Key Points for Employers

Hiring is exciting - but it can feel risky if you’re not sure someone is the right fit yet. That’s where a probation period helps. Done well, a probationary period gives you breathing room to train, assess and decide whether to confirm ongoing employment, extend probation (where appropriate), or part ways lawfully.

In this guide, we’ll break down how probation works under Australian law, the difference between a contractual probation period and the legal “minimum employment period”, and what you need to do to manage performance or end employment safely during probation. We’ll also share practical steps, templates and policies to put in place so your business is protected from day one.

What Is A Probation Period In Australia?

A probation period is a clause you include in an employee’s contract that sets an initial period at the start of employment where you evaluate performance, conduct and cultural fit. It’s not a separate employment type - employees on probation are still employees with the usual National Employment Standards (NES) rights (e.g. paid personal/carer’s leave for full-time and part-time staff, and minimum notice of termination).

It’s helpful to keep two concepts separate:

• Probationary period (contractual): The period you set in the employment contract (commonly three or six months) with specific expectations, review points and easier exit steps.
• Minimum employment period (Fair Work Act): The legal threshold for unfair dismissal protection - generally six months, or 12 months for a small business employer with fewer than 15 employees.

These two periods can overlap, but they’re not the same thing. An employee can be “on probation” for three months yet still not qualify for unfair dismissal until they reach six months (or 12 months for a small business). Equally, you could set a nine-month probation period, but after the relevant minimum employment period passes, the employee may be able to bring an unfair dismissal claim if you terminate for performance without a fair process.

Also keep in mind that general protections (adverse action) and discrimination laws apply from day one. Even during probation, you must not take adverse action for prohibited reasons (e.g. because the employee is sick, pregnant or makes a complaint about their employment).

How Long Should A Probationary Period Be?

There’s no one-size-fits-all rule. Probation should be long enough to properly onboard and assess the role. In practice, most employers choose either a three-month probation period or a six-month probation period, depending on the role’s complexity and seniority.

• 3 month probation period: Common for junior or operational roles where performance can be assessed quickly.
• 6 month probation period: Useful for higher responsibility roles, where deliverables and stakeholder feedback take longer to assess.

If you’re a small business employer (fewer than 15 employees), the minimum employment period for unfair dismissal is 12 months. Some small businesses align probation to 6 months for a clear internal checkpoint, then continue structured reviews up to the 12‑month mark to reduce risk.

Can you have no probation period in the contract? Yes - probation is optional. But removing it means you miss the chance to set clear expectations, review milestones and simplified notice terms early on. In most cases, including a fair and transparent probation clause is best practice.

What about casual employees? Casuals typically don’t need a formal probation clause because each shift is a separate engagement and there’s no ongoing commitment. If you still want to use one for clarity, keep it simple and make sure it’s consistent with casual rights. For more detail, see probation periods for casual employees and how they work in practice.

How To Set Up Probation Properly In Employment Contracts

A strong probation process starts with the right contract. Your contract should spell out the length of probation, what success looks like, how reviews will work, and what happens at the end (confirmation, extension or termination with notice).

Must-have terms in a probation clause

• Length and start date: State when probation starts (usually the first day of employment) and the duration (e.g. three or six months).
• Performance standards: Reference the position description and any KPIs or behavioural expectations.
• Review process: Include check-ins (e.g. at 4 and 8 weeks) and a formal review near the end of probation.
• Extension option: Allow a short, reasonable extension if more time is genuinely needed (for example, if onboarding was disrupted), noting that unfair dismissal eligibility may have already commenced.
• Termination during probation: Reserve the right to terminate with the required notice (or payment in lieu), consistent with the NES and any applicable modern award.

Make sure these terms sit within a legally sound Employment Contract that covers hours, duties, remuneration, confidentiality, IP ownership, restraints, and dispute resolution.

Policies and position descriptions matter

Your policies and PDs are where expectations become real. Provide a clear position description on day one and ensure core policies (e.g. code of conduct, performance and conduct, leave, WHS) are up to date. If you haven’t compiled them yet, implement a practical Workplace Policy suite alongside your contracts so managers can apply consistent standards during probation.

Awards and enterprise agreements

Check whether a modern award covers the role. Some awards include requirements about classification, minimum rates, and notice. Your contract and probation settings must meet or exceed those obligations. When in doubt, get advice before finalising your template for a new recruitment round.

Managing Performance During Probation: Practical Steps For Employers

Probation isn’t just a waiting period. It’s an active process where you support, assess and document performance. A structured approach strengthens your team and reduces risk if you decide to end employment.

Set expectations early

• Provide a written induction plan for the first 4-6 weeks.
• Walk through KPIs and the position description line by line.
• Explain how performance will be reviewed and what good looks like.

Schedule regular check-ins

• Book diary time at week 2, 4, 8 and a final meeting two weeks before probation ends.
• Use each check-in to give specific feedback, agree on action items and confirm support needed (training, tools, shadowing).
• Send short follow-up emails documenting what was discussed and agreed.

Address issues early and fairly

If performance or conduct falls short, act quickly and proportionately. For moderate concerns, written coaching and a short performance improvement plan during probation is often enough. For more serious issues, consider a formal process - typically a letter outlining the concerns, evidence, and giving a genuine chance to respond before you make any decision.

When concerns escalate, many employers rely on a structured performance management process and, where appropriate, a carefully drafted show cause letter that gives the employee procedural fairness.

Confirm outcomes in writing

• Confirmation: Send a letter confirming the employee has successfully completed probation and outline next steps (e.g. annual review cycle).
• Extension: If you extend probation, explain the reason, the new end date, support you’ll provide, and what improvement is required. Keep extensions short and genuine.
• Termination: If you end employment, follow the notice rules below and provide a concise termination letter.

Ending Employment During A Probation Period: What Are The Rules?

As an employer, you can terminate during probation - but it must be done lawfully and respectfully. The big questions we hear are about notice, unfair dismissal risk and final pay.

Notice or payment in lieu

The NES sets minimum notice for permanent employees based on length of service. During a short probation, this often means one week’s notice (unless serious misconduct). You can either have the employee work out the notice, or provide payment in lieu of notice if your contract allows. Always check whether an award prescribes a longer notice period.

For a broader refresher on how notice works at different service milestones, see this overview of calculating employee notice periods.

Unfair dismissal risk and the minimum employment period

Employees generally cannot bring an unfair dismissal claim until they pass the minimum employment period (six months; or 12 months for small business employers). This often overlaps with the probation period you set contractually, which is why many businesses align probation with the six-month threshold.

Even so, you should still follow a fair process and document your reasons. Employees can bring other claims (like general protections/adverse action) from day one if the dismissal is for a prohibited reason. Thoughtful performance management and clear records are your best protection.

If you need a deeper dive on process, we’ve covered the do’s and don’ts of termination during probation in more detail here.

Final pay and entitlements

• Pay any owed wages up to the termination date.
• Pay out accrued but untaken annual leave for permanent employees.
• Superannuation is payable on ordinary time earnings; check any specific inclusions under OTE for termination payments.
• Provide a separation certificate if requested and you are able to do so under Services Australia requirements.

Common mistakes to avoid

• Relying on “probation” to ignore the law: Probation doesn’t suspend the NES, anti-discrimination laws or general protections.
• Setting probation longer than needed without reviews: Long probation with no structured feedback can look arbitrary and unfair.
• Not aligning contract notice with the NES/award: If your contract undercuts the minimum, the law wins - but the inconsistency can create disputes.
• Terminating without records: Keep notes of training, feedback and performance discussions to evidence your legitimate reasons.

Step-By-Step Checklist To Implement Probation In Your Business

1) Choose the right probation length for the role

Use three months for simpler roles; up to six months for complex or leadership roles. For small business employers, plan structured check-ins through the 12‑month minimum employment period as a risk control.

2) Update your contract template and policies

Embed a clear probation clause in your Employment Contract and ensure your policies support managers to implement it consistently. If you employ casuals regularly, consider a separate casual letter of offer and refer to the guidance on probation for casual employees.

3) Set up a structured onboarding and review schedule

Book the reviews in your HR system or calendar on day one. Use a simple template agenda for each check-in so feedback is consistent.

4) Document feedback and support

Follow each meeting with a brief bullet-point email: what’s going well, what needs to change, what support is being provided, and the next review date. If issues persist, escalate to a short improvement plan or a formal performance management process as needed.

5) Decide early and act with notice

Two weeks before probation ends, decide whether to confirm, extend briefly (with clear reasons) or terminate with the correct notice or payment in lieu. Confirm the decision in writing and process final pay promptly if ending employment.

6) Continually refine

Gather feedback from managers after each probation cycle and tweak your templates, PDs and training plan. A small improvement in onboarding can meaningfully lift retention and reduce risk.

FAQs Employers Ask About Probation

Can I dismiss during probation without giving a reason?

You’re not legally required to provide a detailed reason, but it’s best practice to outline the legitimate business or performance reasons for your decision. This helps demonstrate that your decision was not for a prohibited reason and supports employee dignity.

Can I extend probation?

Yes, if your contract allows. Keep extensions short and genuine - for example, where a project delay prevented proper assessment. Be aware that the unfair dismissal minimum employment period may have already passed, which increases your risk if you terminate later without a fair process.

Do casuals have a probation period?

Casuals don’t usually need a formal probation clause. Because each shift is a separate engagement, you can simply stop offering shifts if there’s no ongoing commitment. If you do include a casual probation clause, ensure it doesn’t conflict with casual conversion rules or casual rights.

What if an award says something different?

The NES and any applicable modern award set minimums. Your contract and probation process must meet or exceed those. Always check the award classification, rates, and any notice provisions that apply to the role.

Should I use a show cause letter during probation?

If you’re considering termination for conduct or performance, a short, well-drafted show cause letter can help you provide procedural fairness. It isn’t legally mandated in every case, but it’s often a sensible step to reduce risk.

Key Takeaways

• A probation period is a contractual tool for you to assess fit, but it doesn’t override the NES, anti-discrimination laws or general protections.
• The unfair dismissal minimum employment period is six months (or 12 months for small business); align your reviews with these thresholds.
• Set probation up properly in your Employment Contract, with clear expectations, review timing, extension options and lawful notice.
• Manage probation actively - onboard well, hold regular check-ins, document feedback and escalate issues through a fair performance management process if needed.
• When ending employment, follow the correct notice or provide payment in lieu, and process final pay accurately and promptly.
• If you need to terminate during probation, a fair process and clear records help reduce the risk of disputes, even before unfair dismissal eligibility kicks in.
