Instant Dismissal In Australia: What Employers Need To Know

Serious misconduct can put your business, people and customers at risk. In those rare moments, you may feel you have no option but to end employment immediately - often called “instant” or “summary” dismissal.

Handled correctly, summary dismissal can be lawful and necessary. Handled poorly, it can expose your business to unfair dismissal, general protections, or breach of contract claims.

This guide breaks down when instant dismissal is appropriate, what “serious misconduct” actually means, and the fair process employers should follow so you can act quickly, confidently and lawfully.

What Is Instant Dismissal In Australia?

Instant dismissal (also called summary dismissal) is the termination of employment without notice where an employee engages in serious misconduct.

Under Australian employment law, “serious misconduct” is behaviour so serious that it makes continuing the employment relationship untenable. Common features include wilful or deliberate behaviour that’s inconsistent with the continuation of employment, or conduct that causes serious and imminent risk to the health or safety of a person, your reputation, viability or profits.

In practice, summary dismissal is the exception, not the rule. Most terminations require notice or payment in lieu of notice. You should only move to instant dismissal where the facts support serious misconduct and you have afforded basic procedural fairness (more on process below).

When Is Summary Dismissal Reasonable?

Serious misconduct will always turn on the facts, but the following types of conduct often justify instant dismissal when supported by clear evidence:

• Theft, fraud or deliberate falsification of records.
• Assault, threats of violence, or serious harassment or discrimination.
• Serious breaches of work health and safety obligations that create imminent risk.
• Unauthorised possession or use of drugs or alcohol at work where safety is compromised.
• Deliberate and serious damage to company property, systems or reputation.
• Serious confidentiality breaches, sabotage, or significant policy breaches after warnings.

Even if the alleged conduct looks like serious misconduct, you still need to consider context and credibility: what happened, the employee’s explanation, evidence available, consistency with how you’ve treated similar cases, and the employee’s length of service and record.

Importantly, the Fair Work Commission (FWC) also looks at the overall fairness of the dismissal. The factors in Section 387 of the Fair Work Act include whether the employee was warned about unacceptable performance (if relevant), whether they were notified of the reason for dismissal, given a chance to respond, and whether a support person was allowed in relevant meetings. Even for serious misconduct, a fair process matters.

The Right Process: Managing Serious Misconduct Step-By-Step

Speed is crucial when something serious happens - but so is process. Following a clear, fair and well-documented process is often the difference between a lawful summary dismissal and an avoidable claim.

1) Stabilise The Situation And Preserve Safety

• Remove any immediate risks (e.g. separate individuals, secure systems or equipment).
• Consider a short, paid suspension to allow a fair inquiry. It’s common to suspend pending investigation while you gather facts.
• Secure and preserve evidence (CCTV, emails, system logs, witness names, photos).

2) Identify The Issues And Review Your Documents

• Pinpoint the conduct you’re investigating and the policies or clauses potentially breached (e.g. code of conduct, confidentiality, WHS, bullying and harassment).
• Check the employee’s Employment Contract and your workplace policies for investigation and disciplinary procedures, confidentiality, suspension provisions and grounds for summary termination.

3) Put The Allegations In Writing (And Use Clear Language)

• Provide written particulars of the alleged conduct, the evidence you’ll rely on, and the possible outcomes (including summary dismissal).
• Give the employee a reasonable opportunity to respond in writing and at a meeting.
• Allow a support person to attend meetings, consistent with fairness expectations under the Fair Work Act.

It’s helpful to frame this letter as a formal show cause letter. That structure helps you cover the key elements a decision-maker (or the FWC) will later look for.

4) Conduct A Fair Investigation

• Interview relevant witnesses and the employee; gather and test evidence objectively.
• Keep notes and chronology; avoid pre-judging the outcome before you’ve heard the response.
• Consider whether the conduct, if substantiated, would amount to serious misconduct.

5) Make A Decision And Document Your Reasoning

• Weigh what is substantiated on the balance of probabilities (is it more likely than not?).
• Consider individual circumstances (service, record, consistency with past practice).
• Decide on the outcome: no action, warning, final warning, dismissal with notice, or summary dismissal.

Communicate the decision in writing. If you decide on summary dismissal, specify the serious misconduct, the policy or contractual clauses breached, the material relied on, and the effective date. Keep the letter succinct and factual.

6) Notice And Final Pay: Do You Need To Pay Anything?

If dismissal is truly summary (for serious misconduct), you don’t provide notice. However, you still pay all accrued but unused entitlements such as wages up to the last day worked, annual leave, and any applicable allowances or reimbursements.

Where the conduct does not reach the “serious misconduct” threshold, you should either work out the notice period or make a lawful payment in lieu of notice. The amount of notice typically depends on the employee’s contract, modern award or the National Employment Standards (NES).

Include a clear breakdown of final pay in the termination letter. If you’re unsure about entitlements, awards or offsets, it’s best to get advice before finalising the payment calculation.

7) Return Of Property, Confidentiality And Post-Employment Obligations

• Collect keys, passes, devices and disable access (email, CRM, shared drives, messaging apps).
• Remind the employee of confidentiality and intellectual property obligations.
• If restraint clauses apply, note them in the outcome letter and keep a record of delivery.

8) Consider A Risk-Managed Exit

In some situations, even with serious allegations, an immediate exit may not be the best path. Depending on your contracts and policies, you might consider alternatives such as temporary garden leave while you finalise investigations, or a without-prejudice conversation about a negotiated exit (handled carefully to avoid undue pressure). Whichever route you take, stick to a consistent, fair process and document every step.

Contracts, Policies And Records To Protect Your Business

Instant dismissal decisions are much easier - and safer - when your paperwork is in order. Solid contracts, clear policies and consistent records will reduce disputes, guide managers and show the FWC you acted reasonably.

• Employment Contract: Your Employment Contract should define serious misconduct, allow suspension in appropriate cases, outline notice provisions, and include confidentiality, IP and restraint clauses suited to your business.
• Workplace Policies: Up-to-date policies covering code of conduct, bullying and harassment, discrimination, WHS, drugs/alcohol, social media, IT/communications, grievance handling and investigations set expectations and support disciplinary decisions.
• Performance And Conduct Framework: A fair performance management and investigation process helps you treat employees consistently and demonstrate procedural fairness. If you need ready-to-use templates and letters, consider a structured set of termination documents to standardise your approach.
• Position Descriptions And Inductions: Clear duties and training records can be critical where misconduct relates to safety or compliance.
• Record-Keeping: Keep thorough notes of incidents, interviews, evidence and decisions. Good records are a strong defence if a claim is made.

Key Risks And How To Avoid Them

Summary dismissal carries legal risk. Here are the main pitfalls and how to manage them.

Unfair Dismissal (Harsh, Unjust Or Unreasonable)

Employees who meet eligibility thresholds may claim unfair dismissal. The FWC will consider whether there was a valid reason related to conduct or capacity, plus the fairness of your process against the factors in Section 387 of the Fair Work Act.

Risk reduction tips:

• Base your decision on reliable evidence and address relevant explanations.
• Notify the employee of the reasons and give a genuine chance to respond.
• Allow a support person and follow your own policies consistently.
• Issue a clear, polite and factual termination letter.

General Protections (Adverse Action)

It’s unlawful to take adverse action because an employee exercises a workplace right (e.g. making a complaint, taking leave) or for discriminatory reasons. Beware of timing - if serious misconduct occurs shortly after a complaint or during protected leave, ensure your records show the conduct (not the protected reason) drove the decision.

Breach Of Contract And Notice Claims

If the conduct falls short of serious misconduct but you withhold notice, you risk a breach of contract claim. Where instant dismissal isn’t clearly justified, provide notice or payment in lieu, and explain the calculation in writing.

Investigation Missteps

Cutting corners on process is a common error. If the situation is volatile, you can pause the immediate pressure by using a short, paid suspension while you gather facts, as outlined in the guide to suspending an employee pending investigation. Then proceed with a structured show cause letter and fair meeting process.

Probation And Junior Tenure

Instant dismissal can still be risky during probation if process is unfair. Probationary employees may not be eligible for unfair dismissal (depending on service length and business size), but they still have access to other claims (e.g. general protections). A fair process remains best practice when you’re terminating during probation.

Communication And Dignity

How you communicate matters. Keep conversations private, professional and consistent with your letters. Treating the employee with dignity reduces reputational risk and the likelihood of disputes.

Key Takeaways

• Instant (summary) dismissal is only appropriate for serious misconduct that makes continued employment untenable, supported by clear evidence.
• A fair process is essential: stabilise risk, consider a short suspension, put allegations in writing, give a genuine chance to respond, and document your decision.
• If the threshold for serious misconduct isn’t met, provide notice or make a lawful payment in lieu of notice and include all final entitlements.
• Solid foundations help: a robust Employment Contract, clear policies, and consistent records will support lawful decisions and reduce disputes.
• The FWC assesses both your reason and your process using the factors in Section 387 of the Fair Work Act - following a documented, fair process is your best protection.
• Where circumstances are complex, consider interim steps (e.g. garden leave or suspension) and use a structured suite of termination documents to stay consistent.
