Reasons for Dismissal in Australia: What Employers Should Know

Dismissing an employee is one of the toughest calls you’ll make as a business owner. Done well, it protects your team and your business. Done poorly, it can lead to costly claims, reputational damage, and stress for everyone involved.

If you’re wondering what counts as a valid reason for dismissal in Australia - and how to manage the process fairly - this guide walks you through the key concepts in plain English. We’ll cover lawful reasons for termination, what to avoid, the steps to follow for a fair process, and the core documents you should have in place before you act.

Our goal is to help you make confident, compliant decisions so you can manage risk and keep your business moving forward.

What Counts As A Valid Reason For Dismissal In Australia?

Under Australian employment law, you generally need a valid reason for dismissal and a fair process. A “valid reason” usually falls into one of the categories below.

1) Conduct (Including Serious Misconduct)

Misconduct covers things like repeated breaches of policy, dishonesty, harassment, bullying, theft, or safety breaches. Very serious misconduct (for example, theft or assault) may justify summary dismissal - meaning termination without notice - if you can substantiate the conduct and follow a fair process.

2) Performance (Poor Performance Or Unsatisfactory Work)

If an employee is not meeting reasonable performance expectations, you can consider dismissal - but only after a clear process. This usually involves setting expectations, providing feedback and training, issuing warnings, and giving the employee a real chance to improve.

3) Capacity (Including Medical Incapacity)

Capacity relates to an employee’s ability to perform the inherent requirements of their role. Long-term illness or injury can affect capacity, but this area is sensitive and must be handled carefully to avoid discrimination or adverse action risks. Get advice early if you’re considering termination on medical grounds.

4) Redundancy (Genuine Operational Reasons)

If the role itself is no longer required due to changes in your business (for example, restructuring or a downturn), a genuine redundancy may be a valid reason for ending employment. Redundancy isn’t about the person’s performance - it’s about the role no longer being needed. Make sure it’s genuine, consult where required, and pay any redundancy entitlements that apply.

As a quick reference, Fair Work decision-makers look at both the reason and the process. If you’re unsure whether your reason qualifies, it’s worth checking how decision-makers assess dismissals under the fairness criteria in section 387 of the Fair Work Act.

Lawful Vs Unlawful Reasons: What’s The Difference?

Lawful reasons for dismissal include conduct, performance, capacity, or genuine redundancy - provided you follow a procedurally fair process.

Unlawful reasons (which you must avoid) include dismissing someone because of a protected attribute or because they exercised a workplace right. Examples include termination because an employee:

• Took parental leave, sick leave, or made a workplace complaint
• Joined a union or engaged in industrial activities
• Has a protected attribute (e.g. race, sex, age, disability, religion)
• Took a temporary absence due to illness or injury (within the protections of the National Employment Standards)

Even if you have a valid reason, a dismissal can still be unfair if the process wasn’t fair - for example, if you didn’t warn the employee about performance concerns or didn’t give them a chance to respond to the allegations.

How Do You Manage A Fair Dismissal Process?

A fair process protects your business. It shows you acted reasonably, gave the employee a chance to respond, and made a considered decision. While every case is different, employers typically follow the steps below.

Step 1: Investigate And Gather Facts

Start by gathering evidence. For conduct matters, that might include documents, CCTV, emails, witness statements, and policy references. For performance issues, collect objective examples, KPI data, customer complaints, training records, and prior feedback.

Where appropriate, consider whether to keep the employee at work, place them on paid suspension, or stand them down during the investigation. If you need breathing room to preserve evidence or protect the workplace, you can consider suspending an employee pending investigation or, in specific circumstances, standing them down pending investigation.

Step 2: Provide Procedural Fairness

Outline the concerns in writing and give the employee the material you’re relying on (to a reasonable extent). Invite a written response and/or a meeting to discuss the issues. Let them bring a support person. Keep detailed notes.

For performance issues, a performance improvement plan (PIP) and a clear timeline can be useful. For conduct issues, a formal “show cause” process is common - you put the allegations to the employee and ask them to show why their employment should not be terminated. If you need help, see this plain-English overview on show cause letters.

Step 3: Make A Decision And Communicate It Clearly

After considering the employee’s response and all evidence, decide on the appropriate outcome. Options include no action, training or coaching, a formal warning, final warning, or termination. If you decide to dismiss, set out the reason clearly in a termination letter and note the effective date, notice (or payment in lieu), and any final entitlements payable.

If you intend to pay out notice rather than have the employee work it, make sure you handle payment in lieu of notice correctly and check any award or contract terms that apply.

Step 4: Handle Notice, Final Pay And Property

Calculate the correct notice (subject to any serious misconduct or probation period rules), accrued annual leave and, if applicable, redundancy pay. Collect company property and revoke access to systems. Some employers choose to place employees on garden leave during their notice period to protect clients and confidential information - make sure your contract allows this.

Step 5: Keep Records

Keep copies of investigation notes, emails, warnings, meeting notes, and the termination letter. Good records help you demonstrate a valid reason and a fair process if a claim is made later.

Common Lawful Reasons For Dismissal (With Examples)

Let’s look more closely at reasons that commonly lead to lawful termination - and what you should keep in mind to do it fairly.

Serious Misconduct

Examples include theft, fraud, assault, serious breaches of safety, wilful refusal to follow lawful and reasonable directions, or serious harassment. These can justify summary dismissal, but you still need to investigate, give the employee a chance to respond, and make a defensible decision.

Repeated Underperformance

If an employee continues to miss targets or make serious errors despite feedback and support, dismissal can be fair. The key is documentation. Spell out expectations in the Employment Contract, set measurable KPIs, and document your performance management process. Warnings should be clear about what needs to change and the consequences if it doesn’t.

Capacity Or Fitness For Work

Where an employee can’t perform the “inherent requirements” of the role, dismissal may be lawful - but tread carefully. Explore reasonable adjustments, consider medical evidence, and ensure you’re not breaching discrimination laws. If the issue is long-term illness or injury, read up on your obligations before considering termination on medical grounds.

Genuine Redundancy

When a role is no longer required for operational reasons, you can make the position redundant. Consult as required, check redeployment opportunities, and pay entitlements if they apply. Remember, redundancy is about the role - not the person’s performance. If you’re weighing up whether it’s really redundancy or performance-based termination, this quick explainer on the difference between redundancy and termination will help you frame your decision.

Probation

Many employers use a probation period to assess fit and performance. While employees on probation still have rights, it’s often simpler to end employment during probation (with required notice) if it’s not working out. If that’s on your mind, read through this guide to terminating employment during probation to avoid missteps.

Risky Or Unlawful Reasons You Must Avoid

Some reasons for dismissal are unlawful, and others are simply risky because they’re easy to misinterpret or poorly evidenced. Here’s what to avoid.

• Discrimination: Terminating because of a protected attribute (such as age, disability, pregnancy, race, sex, religion) is unlawful.
• Adverse Action: Terminating because an employee exercised a workplace right (for example, making a complaint or taking leave) can trigger general protections claims.
• Temporary Absence Due To Illness/Injury: Dismissal because someone is temporarily absent due to illness/injury can breach protections.
• Retaliation: Firing someone for raising health and safety concerns or refusing unsafe work is unlawful.
• “No Reason” With No Process: Failing to warn, consult, or consider responses can make even a valid reason look unfair.

If you’re unsure whether your reason is safe, step back and stress-test it: is the reason documented, reasonable, and genuinely connected to the role or the conduct? Have you given the employee a fair chance to respond? If you can’t answer “yes” to both, pause and get advice.

Alternatives To Dismissal You Should Consider

Dismissal isn’t always the best or only path. Often, less drastic options can protect your business and resolve the issue.

• Training and Support: Address skill gaps through coaching, mentoring, or short courses.
• Performance Improvement Plans: Set clear goals, timeframes, and support - then reassess.
• Warnings: Issue formal warnings that outline the issues and consequences if things don’t improve.
• Redeployment: If the role is changing or the fit isn’t right, consider suitable redeployment options.
• Suspension Or Stand Down: Where safety, evidence preservation, or serious allegations are involved, use suspension pending investigation or, in specific circumstances, stand down pending investigation.
• Garden Leave: Keep the employee away from the workplace during notice to protect clients and confidential information - check your contract permits garden leave.

Exploring alternatives shows fairness and can significantly reduce your legal risk if dismissal becomes necessary later.

The Documents And Policies That Make Dismissals Safer

The right documents make your expectations clear, support fair processes, and reduce disputes. At minimum, small businesses should consider the documents below.

• Employment Contract: Sets out duties, policies, misconduct definitions, notice, and rights around suspension, garden leave, and termination.
• Workplace Policies: Clear rules on conduct, performance, harassment and bullying, WHS, social media, confidentiality, and investigations.
• Performance Management Process: A simple, documented pathway for feedback, PIPs, and warnings so the process is consistent and fair.
• Show Cause Letter: Used in conduct or serious performance matters to put allegations to an employee and invite a response.
• Termination Letter And Checklist: Confirms the reason, last day, notice (or payment in lieu), entitlements, property return, and confidentiality reminders.
• Employee Termination Documents Suite: A practical set of templates and guidance to manage termination steps consistently.

If you manage complex or sensitive matters (for example, medical capacity or alleged serious misconduct), it’s best to get tailored advice before you send letters or make final decisions.

Practical Tips To Reduce Unfair Dismissal Risk

A few simple habits will go a long way to protecting your business.

• Set Clear Expectations Early: Role descriptions, KPIs, and policies should be part of onboarding and reinforced regularly.
• Keep Notes: Document meetings, warnings, and agreed improvement steps - contemporaneous records carry weight.
• Be Consistent: Treat similar issues similarly to avoid claims of unfairness or discrimination.
• Use Measured Language: Stick to facts in letters and conversations; avoid speculation or emotional language.
• Offer A Support Person: It’s a basic fairness step that tribunals expect, and it builds trust in the process.
• Pause If Emotions Run High: If a meeting escalates, adjourn and reconvene later - rushing leads to mistakes.
• Sense-Check Against Fairness Criteria: Before deciding, reflect on the fairness factors in section 387 of the Fair Work Act to see how your conduct might be assessed.

Key Takeaways

• A valid reason for dismissal in Australia usually relates to conduct, performance, capacity, or genuine redundancy - paired with a fair process.
• Unlawful reasons (like discrimination or retaliation for using workplace rights) are off-limits and carry high legal risk.
• A fair process involves investigation, procedural fairness, clear communication, and correct notice or payment in lieu where applicable.
• Explore alternatives first - training, warnings, redeployment, or temporary measures like suspension pending investigation - to show fairness and reduce risk.
• Strong documents (an up-to-date Employment Contract, policies, show cause and termination letters) make difficult decisions defensible.
• When issues touch medical capacity, serious misconduct, or redundancy, get advice early to avoid costly mistakes.
