How to Fire Someone in Australia Legally and Fairly

Letting an employee go is one of the toughest parts of running a small business. You’re balancing legal obligations, team morale and your business’ reputation - all while trying to do the right thing.

The good news is that if you follow a clear, fair process that aligns with Australian law, you can reduce the risk of unfair dismissal claims and feel confident in your decision.

In this guide, we’ll walk through when you can lawfully terminate employment, the steps to follow before you fire someone, what to include in the termination letter and final pay, and the key risks to watch. We’ll also point you to the essential documents and policies that help make this process smoother.

When Can You Fire Someone In Australia?

In Australia, you can terminate an employee’s employment for many legitimate reasons - but the reason must be valid and you must follow a fair process. Typically, valid reasons fall into these categories:

• Conduct: Misconduct (e.g. breach of policy, continued lateness, insubordination) or serious misconduct (e.g. theft, violence, serious safety breach). Serious misconduct can justify summary dismissal (no notice), but you still need a procedurally fair process.
• Capacity/Performance: The employee can’t meet the inherent requirements of the role despite support and clear warnings (e.g. sustained underperformance).
• Redundancy: The role is no longer required due to operational changes. Redundancy has its own rules (consultation, exploring redeployment, and potential redundancy pay) and is different from performance or conduct termination.
• End of Probation: You can terminate during probation more easily, but you must still comply with notice, anti-discrimination laws and any award or contract terms.

Your reason must be genuine and supported by evidence. It should not be harsh, unjust or unreasonable in the circumstances - especially for employees who are protected from unfair dismissal under the Fair Work Act 2009 (Cth).

Small businesses (fewer than 15 employees) must follow the Small Business Fair Dismissal Code. For larger businesses, the Fair Work Commission will consider procedural fairness and whether there was a valid reason when reviewing dismissals.

What Process Should You Follow Before Termination?

A fair, documented process is your best protection if the termination is challenged. While the specific steps depend on the issue (conduct vs performance vs redundancy), these fundamentals apply in most non-redundancy cases.

1) Check Your Documents First

• Review the Employment Contract, any applicable modern award or enterprise agreement, and your policies (e.g. performance, conduct, IT, WHS).
• Confirm probation status, notice periods, disciplinary steps, and any consultation or procedural requirements you must meet.

2) Investigate And Gather Evidence

• For misconduct allegations, conduct a prompt and impartial investigation. Collect documents, CCTV, emails and witness statements where relevant.
• If there’s a potential risk to safety or business integrity, consider standing down an employee pending investigation (where legally permitted) or temporarily adjusting duties.

3) Offer Procedural Fairness

• Provide the employee with the allegations or performance concerns in writing and enough detail for them to respond.
• Invite them to a meeting, let them bring a support person, and give them a genuine opportunity to respond and provide their side.
• Consider their response before making a decision. Take notes and keep a clear paper trail.

4) Use Warnings And Support For Performance Issues

• For underperformance, issue clear performance expectations, reasonable timeframes to improve, and support (training, mentoring, reasonable adjustments).
• Document formal warnings. A structured letter and process can help - see practical guidance on show cause letters when appropriate.

5) Consider Probation Rules

• Probation does not remove your legal obligations, but it can streamline the process, provided you comply with the contract, notice and anti-discrimination laws.
• For a deeper look at this scenario, read the guide on terminating employment during probation.

6) Decide And Communicate

• If termination is warranted, decide whether it’s termination with notice, payment in lieu of notice, garden leave, or (for serious misconduct) summary dismissal.
• Confirm the decision in a meeting, then issue a termination letter that sets out the key details and next steps (more on this below).

This all might sound formal, but following a consistent, fair process shows you’ve acted reasonably. It also helps the rest of your team see that standards are applied fairly.

Notice, Garden Leave Or Payment In Lieu - What’s Required?

In most cases, you’ll either require the employee to work out their notice, direct them to take garden leave during the notice period, or pay out notice instead of having them work.

Notice Periods

• The National Employment Standards (NES) set minimum notice periods based on service length (contracts and awards can specify more generous terms).
• Notice does not apply for summary dismissal due to serious misconduct, but you should only take that step when the evidence and circumstances clearly support it.

Garden Leave

• Garden leave means the employee remains employed (and paid) during notice but is not required to work. This can help protect client relationships, data and morale.
• Check the contract for a garden leave clause or consider what’s reasonable for your business if there isn’t a specific clause.

Payment In Lieu Of Notice

• You can pay out some or all of the notice period and end employment immediately. Make sure the contract or award allows this, and document it in the termination letter.
• There are important payroll and super considerations - see this practical guide to payment in lieu of notice for employers.

What Should The Termination Letter And Final Pay Include?

Your termination letter and final pay are the last touchpoints of the employment relationship - getting them right matters legally and professionally.

What To Include In The Termination Letter

• Employee’s name and position, and the date of the letter.
• Confirmation that employment is terminated and the effective date (consider whether it’s with notice, garden leave or payment in lieu).
• Any key reasons (many employers provide a brief, factual reason - keep it accurate and consistent with your process and evidence).
• Entitlements to be paid on termination (e.g. outstanding wages, accrued annual leave, and other amounts under an award, agreement or contract).
• Company property return steps (devices, keys, cards, documents) and confidentiality obligations post-employment.
• Contacts for queries and how the employee will receive their final payslip and documents.

Final Pay

• Calculate and pay all owed amounts within the required timeframe (check any applicable award, contract or state rules for timing).
• Include outstanding wages, accrued annual leave, and any other contractual or award entitlements. Long service leave depends on state and service length.
• Double check payroll and super on termination amounts - this step-by-step overview on calculating final pay can help.

Handle access removals and property returns promptly and professionally. It’s important to keep personal data secure and continue to comply with privacy obligations even after employment ends.

Common Risks When You Fire Someone (And How To Avoid Them)

Most disputes arise from either the reason for dismissal or the process you followed. These are the big risks to keep in mind.

Unfair Dismissal

• Employees who are eligible for unfair dismissal protection can challenge terminations that are harsh, unjust or unreasonable. The Fair Work Commission looks at factors in section 387 of the Fair Work Act, including whether there was a valid reason, whether the employee was notified of the reason, and whether they had a chance to respond.
• Strong documentation and a fair process are your best defence.

General Protections (Adverse Action)

• It’s unlawful to take adverse action (including firing) because someone exercised a workplace right, engaged in industrial activity or due to protected attributes (e.g. sex, race, disability, pregnancy, carer’s responsibilities).
• Keep a clear record of the real reason for dismissal and ensure it’s unrelated to any protected reason.

Discrimination

• Terminating someone because of a protected attribute is unlawful. Be especially careful where performance or capacity issues may be linked to disability, illness or injury - you must consider reasonable adjustments.
• Seek advice if there are medical or capacity questions; you may need a lawful, evidence-based assessment of inherent requirements before making a decision.

Procedural Missteps

• Skipping warnings, not offering a support person, or failing to consider the employee’s response can tip an otherwise valid termination into “unfair” territory.
• Use consistent templates and a checklist so you don’t miss key steps.

Pay And Notice Errors

• Incorrect notice, underpaying entitlements, or delays in final pay create risk and can become the focus of a dispute.
• Cross-check the award or agreement and your contract, and confirm any industry-specific rules.

Essential Documents And Policies That Make Termination Smoother

Having clear, tailored documents in place before things go wrong makes a huge difference. At a minimum, make sure you have:

• Employment Contract: Sets out duties, performance expectations, policies, notice, confidentiality and post-employment obligations.
• Workplace Policies: Clear rules on conduct, performance management, bullying/harassment, leave, IT and social media. Policies guide day-to-day expectations and help you apply consistent standards.
• Performance Management Process: A simple, documented pathway for raising issues, providing support and issuing warnings - this helps show procedural fairness.
• Confidentiality And IP Clauses: Either in the contract or via a separate non-disclosure agreement to protect sensitive information during and after employment.
• Termination Templates: Structured letters for warnings, show cause, and termination help you communicate clearly and consistently at each step.

If you’re unsure where to start, it’s worth standardising these documents now so you’re ready to act promptly and fairly if problems arise.

Special Cases: Conduct, Capacity And Redundancy

Not all terminations are alike. Tailor your process to the reason you’re ending employment.

Misconduct And Serious Misconduct

• Investigate promptly and fairly, give the employee an opportunity to respond, and consider whether the conduct truly amounts to serious misconduct before deciding on summary dismissal.
• If there’s ongoing risk to your business, consider a lawful stand down or suspension while you investigate.

Underperformance Or Capacity

• Set clear expectations, provide support and time to improve, and document warnings.
• Where an injury or illness is involved, focus on the inherent requirements of the role and reasonable adjustments. Seek medical evidence where appropriate.

Probation

• Probation reduces unfair dismissal risk for many employees, but you still need to act fairly, give required notice, and avoid discriminatory reasons.
• Use the probation period deliberately with regular check-ins so your decision (to confirm or end employment) is evidence-based. See more on termination during probation.

Redundancy

• Redundancy is about the role no longer being required, not the person. You must consult under the applicable award or agreement, consider redeployment across the business (or associated entities), and pay redundancy pay if required.
• Don’t use “redundancy” to mask a performance issue - that’s a fast track to legal trouble. If the role is genuinely not required, follow the redundancy pathway; if it’s a conduct/capacity issue, follow the disciplinary/performance pathway.

Key Takeaways

• You can fire someone for a valid reason (conduct, capacity or redundancy), but you must follow a fair, well-documented process.
• Investigate issues, provide details to the employee, allow a response, and use warnings and support for performance concerns before deciding on termination.
• Choose the right exit method - notice, garden leave or payment in lieu - and confirm everything in a clear termination letter.
• Pay everything owed on time and accurately; a careful approach to final pay avoids many disputes.
• Understand your risk areas - unfair dismissal (see section 387 factors), general protections and discrimination - and document your genuine reason for dismissal.
• Strong foundations matter: a clear Employment Contract, practical policies and consistent templates make termination smoother and safer.
• For misconduct investigations and disciplinary steps, use structured tools like show cause letters and consider lawful options such as standing down during an investigation when needed.
