Instant Dismissal Under Fair Work: What Employers Need To Know

Sometimes, serious conduct issues mean you can’t keep someone in the business even for a day longer. That’s where instant dismissal (also called summary dismissal) comes in.

But moving too quickly, skipping a fair process, or misunderstanding what counts as “serious misconduct” can expose you to unfair dismissal or general protections claims. As a small business, you need a clear, lawful pathway you can follow with confidence.

In this guide, we explain when instant dismissal is permitted under Australian employment law, how to run a quick but fair process, what to pay on termination, and the practical steps you can take right now to protect your business.

What Is Instant (Summary) Dismissal Under Fair Work?

Instant dismissal is termination without notice where an employee’s conduct amounts to serious misconduct. In plain English, it’s behaviour so serious that it destroys the employment relationship and justifies ending it immediately.

Under the Fair Work framework, serious misconduct typically includes things like theft, fraud, assault, serious safety breaches, intoxication at work, or wilful refusal to follow lawful and reasonable directions.

Even when you’re confident conduct is serious, it’s important to act procedurally fair. That usually means a short investigation and giving the employee an opportunity to respond before you decide-often done quickly, but still done properly.

When Is Instant Dismissal Lawful? Serious Misconduct Explained

Not every breach or performance issue is “serious misconduct.” Misclassifying the issue is one of the most common pitfalls for employers.

• Theft, fraud or dishonesty: clear, deliberate acts that undermine trust.
• Assault, harassment or threats: physical or serious verbal misconduct that endangers others or the business’ reputation.
• Serious breaches of safety: conduct that puts people at risk or flagrantly disregards WHS rules.
• Gross insubordination: wilful refusal to follow a lawful, reasonable direction.
• Intoxication at work: where it creates a real safety or performance risk.

By contrast, poor performance, lateness, or less serious policy breaches generally require warnings and an opportunity to improve, not instant dismissal.

If you’re unsure whether conduct is “serious,” consider the factors the Fair Work Commission looks at for unfair dismissal claims, including whether there was a valid reason and whether a fair process was followed. For a quick refresher on those factors, see Section 387.

Step-By-Step: How To Lawfully Dismiss For Serious Misconduct

You don’t need a long, drawn‑out process to act fairly. In urgent situations, the steps below can often be completed within 24-72 hours (sometimes faster), provided you’ve gathered enough facts to make a defensible decision.

1) Stabilise The Situation And Secure Evidence

Act quickly to prevent further risk. This could mean removing system access, pausing rostered shifts, and capturing relevant evidence (CCTV footage, emails, witness notes, device logs).

Keep notes of what you did and why. Clear records become crucial if your decision is later challenged.

2) Consider A Short Suspension Or Stand Down

If the risk is ongoing, consider temporarily removing the employee from the workplace while you investigate. Depending on your contract and policies, that may be a paid suspension, or in limited cases, a stand down.

For the differences and legal guardrails here, see our guides on standing down an employee pending investigation and suspension pending investigation.

3) Run A Brief, Targeted Investigation

Interview relevant witnesses and review documents. Focus on the conduct you believe amounts to serious misconduct, and the policies or directions allegedly breached.

You don’t need to prove matters “beyond reasonable doubt”-but your findings should be reasonable in the circumstances and based on facts, not assumptions.

4) Issue A Show Cause Letter And Meet With The Employee

Give the employee a chance to respond before you decide. A short “show cause” letter sets out the allegations, the evidence you’re relying on, and the potential outcome (including summary dismissal). Offer a meeting time and allow a support person.

Well-drafted show cause letters keep the process on track and reduce disputes about what was said.

5) Consider The Response And Decide

After the meeting (and considering any written response), decide whether the alleged conduct occurred and whether it is serious enough to justify instant dismissal.

Confirm your decision in writing. A termination letter should summarise the findings and the effective date, and set out what pay (if any) will be provided in the final pay.

6) Finalise Entitlements And Return Of Property

Calculate final pay and any outstanding entitlements. Arrange return of company property, cessation of access, and a clean handover where needed.

Where practical, consider a short period of garden leave before termination if you need time to transition work or protect sensitive client relationships (noting garden leave is different to instant dismissal and must be supported by the contract).

Do Small Businesses Have Different Rules? The Small Business Fair Dismissal Code

If you have fewer than 15 employees, the Small Business Fair Dismissal Code may protect you from an unfair dismissal claim-if you follow it properly.

In serious misconduct cases, the Code allows summary dismissal if you reasonably believe the conduct was serious enough to justify immediate termination. However, you should still:

• Identify the conduct clearly (and why it is serious).
• Have a reasonable basis for your belief (e.g. evidence, witness notes).
• Keep records: your notes, letters, evidence reviewed, and the termination letter.

For non‑serious issues (e.g. performance concerns), the Code expects you to warn the employee (preferably in writing), give them a chance to improve, and allow a support person in meetings.

The safest approach is to mirror the short, fair process outlined above even for small businesses. It protects you under the Code and demonstrates procedural fairness if your decision is reviewed.

Notice, Final Pay And Entitlements At Termination

For lawful summary dismissal due to serious misconduct, you don’t pay notice. However, you still pay any accrued entitlements such as outstanding wages and untaken annual leave.

If, after investigation, you decide the conduct isn’t serious enough for summary dismissal, you can still terminate with notice (or pay in lieu of it). If you choose pay in lieu, ensure the calculation is correct and documented-see our practical guide to payment in lieu of notice.

Avoid making unauthorised deductions from final pay unless they’re permitted by law, the award, or a written agreement. For more on this risk area, read about withholding pay.

Common Risks And How To Avoid Them

Instant dismissal is high‑stakes. Here are the main risk hotspots and how to manage them.

• Misclassifying conduct: If the behaviour wasn’t truly “serious misconduct,” summary dismissal may be unfair. Solution: investigate, assess the seriousness objectively, and consider termination with notice if borderline.
• Poor process: Skipping a response opportunity or not allowing a support person can tip a close case against you. Solution: use a short but fair process-show cause, meeting, response, decision.
• Inconsistent treatment: Treating similar cases differently (without a good reason) can undermine your decision. Solution: rely on clear policies and apply them consistently.
• Missing or vague contracts/policies: If expectations weren’t clear, it’s harder to justify dismissal. Solution: ensure each employee has a current Employment Contract and your key policies are up to date and acknowledged.
• Retaliation perception: If timing suggests you dismissed someone for making a complaint or exercising a workplace right, you could face a general protections claim. Solution: document the genuine conduct issues, separate them from any protected activities, and keep records.
• Procedural gaps in small business: Relying on the Code without records. Solution: follow the Code steps and keep a file of your decision‑making.

It also helps to understand how the Commission will evaluate a dismissal if challenged. The factors under Section 387 of the Fair Work Act (valid reason, notification, response opportunity, support person, warnings where relevant, and overall reasonableness) are a useful checklist.

What Documents And Policies Should You Have In Place?

The right documents make it easier to act quickly and fairly when serious issues arise. They also reduce disputes about expectations and process.

• Employment Contract: Sets clear standards, disciplinary procedures, rights to suspend, garden leave, and termination provisions. Each employee should have a signed, current Employment Contract.
• Workplace Policies/Staff Handbook: Establishes rules around conduct, safety, drugs and alcohol, bullying/harassment, IT use, investigations and disciplinary process. A tailored Staff Handbook or Workplace Policy pack helps drive consistent, defensible decisions.
• Show Cause Letter Template: A ready-to-use template ensures allegations are put fairly and clearly, with time for a response. See our explainer on show cause letters.
• Suspension/Stand Down Letter: If your contracts and policies allow, a letter template to confirm a short suspension or stand down during investigations helps manage risk and set expectations.
• Termination Letter And Final Pay Checklist: Documents the decision and what will be paid (e.g. annual leave), including whether notice applies or payment in lieu will be made.
• Employee Termination Documents Suite: Many small businesses prefer a bundled set of letters and checklists to streamline the process; our Employee Termination Documents Suite is designed for this.

Having these items tailored to your business and award coverage means you’re not scrambling in the heat of the moment-your process is clear, fast and compliant.

Key Takeaways

• Instant (summary) dismissal in Australia is only lawful for serious misconduct-think theft, fraud, assault, serious safety breaches or wilful refusal to follow lawful directions.
• A short, fair process is essential: stabilise risk, consider temporary suspension, investigate, issue a show cause letter, hear the response, then decide and document.
• Small businesses can rely on the Small Business Fair Dismissal Code, but you still need a reasonable basis for your belief and good records.
• For genuine summary dismissal, no notice is paid-but you still pay outstanding wages and accrued annual leave; use notice or pay in lieu if the conduct isn’t truly serious.
• Strong foundations-an up-to-date Employment Contract, clear policies, and ready-to-go letters-help you act quickly and avoid unfair dismissal risks.
• Keep good records at every step; the Section 387 factors used by the Commission are a great checklist to test your process and decision.
