Managing Unsuccessful Probation Periods in Australia

Probation periods are designed to help you confirm whether a new hire is the right fit for the role and your business.

Sometimes, despite good intentions on both sides, things don’t work out. When probation is unsuccessful, you need to act fairly, consistently and in line with Australian employment laws.

In this guide, we’ll step through what an unsuccessful probation means for small businesses, your legal obligations, and a practical, low-risk process you can follow from start to finish.

What Is A Probation Period, And Why Does It Matter?

A probation period is a defined window at the beginning of employment where you assess a new employee’s capability, conduct and cultural fit.

It’s set out in the employment contract and typically ranges from 3 to 6 months (sometimes longer for senior roles).

During probation, you should be actively onboarding, setting clear expectations, giving feedback and documenting performance. This way, if probation is unsuccessful, you’ll have the right evidence and processes ready to support a lawful decision.

Can You End Employment After An Unsuccessful Probation?

In many cases, yes-but you must follow the contract and the law. Most businesses can lawfully end employment during probation provided they give the correct notice (or pay in lieu) and avoid unlawful reasons (such as discrimination, adverse action or retaliating against a workplace right).

While unfair dismissal protections usually only apply after the minimum employment period (generally 6 months, or 12 months for small businesses under the Small Business Fair Dismissal Code), general protections and discrimination laws apply from day one. That’s why a structured, documented process is crucial.

For more detail on what you can and can’t do, it’s worth reading Sprintlaw’s guide to terminating employment during probation.

A Practical Process To Manage Unsuccessful Probation (Step-By-Step)

1) Set Expectations Early

Make sure the role description, KPIs and behavioural standards are clear from day one. Confirm the probation length, review points, and what “success” looks like in the Employment Contract.

2) Onboard And Check In

Provide training and resources, schedule regular check-ins and keep short notes of feedback. If issues arise, warn early and specifically. Employees should know what needs to improve and by when.

3) Offer Support And Document Improvements

If performance or conduct falls short, move to a short, tailored improvement plan. Identify the gaps, set realistic targets, agree on support, and record the outcome of each meeting. Documentation matters if the decision is later challenged.

4) Escalate With A Formal Warning (If Needed)

Where performance hasn’t lifted, issue a clear written warning. Outline what’s not working, reference prior feedback, set a final review date, and explain the consequences if improvement isn’t shown. Depending on the issue, you may also use a targeted communication such as a show cause letter before making a final decision.

5) Decide: Confirm, Extend Or End Probation

At the review point, make and communicate your decision:

• Confirm ongoing employment
• Extend probation (if the contract allows it) with a clear improvement plan and new end date
• End employment, providing the required notice period or payment in lieu of notice

If you’re ending employment, meet with the employee (with a support person if they request) and follow up with written confirmation covering the reason, notice, final pay and any company property return.

6) Finalise Entitlements And Offboarding

Process final pay correctly and on time, deactivate access, collect property, and close out confidentiality and post-employment obligations. Keep your records-meeting notes, warnings, letters-together in case you need them later.

What Should Your Contracts And Policies Say About Probation?

Your paperwork sets the tone and protects your business. At a minimum, ensure your Employment Contract clearly states:

• The length of probation and when it starts
• How and when performance will be reviewed
• The notice period during probation (and any right to pay in lieu)
• Whether probation can be extended and how
• Any special conditions (e.g., qualifications, clearances)

It’s also wise to support your contracts with day-to-day rules in your Staff Handbook and key workplace policies (e.g., performance management, grievance, discrimination/harassment, leave and IT use). These help you manage performance consistently and demonstrate procedural fairness if your decision is challenged.

What Notice And Final Pay Are Owed After Unsuccessful Probation?

Even during probation, employees are usually entitled to a minimum notice period under the contract or the National Employment Standards. You can often provide notice or make a lawful payment in lieu of notice.

Get the numbers right. Check your contract or award for employment notice periods and use a clear approach for calculating final pay, including any accrued (but untaken) annual leave and outstanding wages. Depending on the circumstances and payment type, superannuation may also apply to some termination payments-confirm your obligations before processing payroll.

If the employee has been absent on approved leave or has raised a workplace complaint, take extra care to ensure the dismissal decision is not for a prohibited reason. Timing and documentation matter.

Common Risks When Ending Employment During Probation (And How To Avoid Them)

Relying On “Probation” As A Blanket Shield

Probation isn’t a free pass to dismiss for any reason. General protections and discrimination laws apply from day one. Avoid dismissals linked to protected attributes (e.g., age, disability, pregnancy), union activity or complaints about workplace rights.

Not Following Your Own Process

If your contract or policies say you’ll hold reviews, provide feedback or allow a support person, do it. Consistency helps demonstrate procedural fairness.

Insufficient Documentation

In a dispute, contemporaneous notes, emails and warning letters carry weight. Keep concise records of expectations set, training provided, feedback given and responses.

Wrong Notice Or Entitlements

Paying less notice than required, missing leave payouts or misclassifying a role under an award can create avoidable liability. Double-check notice and final pay before issuing the termination letter.

Not Addressing Conduct Concerns Early

Where conduct is the issue (e.g., safety breaches or serious misconduct), you may need to move more quickly and follow an appropriate investigation process. Depending on the risk, consider temporary suspension on pay, then a fair invitation to respond before deciding the outcome.

Templates, Emails And Scripts: What Should The Paper Trail Include?

You don’t need to write a novel-short and clear is usually best. Consider the following artefacts for a clean, consistent file:

• Onboarding plan and role description
• Check-in notes with dates, topics and agreed actions
• Written warning or improvement plan (if used)
• Invitation to a meeting (and mention of a support person, if requested)
• Outcome letter confirming your decision, notice, last day and final pay

Where performance hasn’t lifted despite support, an appropriately worded warning or a targeted show cause letter can reduce risk by demonstrating a fair opportunity to respond.

FAQs: Short Answers To Common Employer Questions

Can I extend probation if I’m unsure?

Often yes-if the contract allows it. Communicate the new end date, what needs to improve and what support will be offered. Confirm the extension in writing before the original probation end date.

Do unfair dismissal rules apply during probation?

Unfair dismissal generally only applies after the minimum employment period (usually 6 months, or 12 months for small businesses). However, general protections and discrimination laws apply from day one, so follow a fair process and document your reasons.

Should I pay out the notice or require them to work it?

It’s up to you, as long as you meet the contract and any award requirements. If keeping an employee on board would be disruptive, a lawful payment in lieu of notice is often cleaner. If they remain at work, ensure appropriate supervision and access controls during the notice period.

Do I need to give a reason?

Providing a clear, factual reason tied to role requirements and documented feedback is good practice and helps defend your decision if challenged. Don’t reference any protected attributes or personal circumstances.

How do I avoid similar issues next time?

Sharpen your hiring criteria, invest in structured onboarding, set measurable goals early, and maintain regular check-ins. Update your contracts and policies so your process is clear and consistent.
