Unfair Dismissal NSW – Thresholds, Eligibility and Application Guide

Jack Charlie Taylor Smith • 2026-04-17 • Reviewed by Sofia Lindberg

Employees in New South Wales who believe their termination was improper may be eligible to lodge an unfair dismissal claim under federal workplace legislation. Understanding the specific thresholds, eligibility rules, and application process is essential before taking action.

Unfair dismissal protections in NSW apply to most private sector workers through the Fair Work Act 2009. However, the system operates on strict eligibility criteria that vary based on business size, employment type, and length of service. Failure to meet these requirements typically results in dismissal of a claim.

This guide explains the thresholds for claiming unfair dismissal in NSW, how the process works through the Fair Work Commission, and what factors employees should weigh before pursuing a case. Detailed information about entitlements and rights is available through Legal Aid NSW and the Fair Work Ombudsman.

What is the threshold for unfair dismissal in NSW?

The minimum employment period required before an employee can claim unfair dismissal differs depending on the size of the business. These thresholds are set by federal law and apply uniformly across NSW.

Eligibility threshold

6 months for businesses with 15+ employees; 12 months for small businesses with fewer than 15 employees

Application deadline

21 days from the date dismissal takes effect

Small business exemption

Small businesses may follow a simplified dismissal code instead of the standard harshness test

Casual and probation coverage

Casual employees qualify only if work was regular and systematic; probation does not shorten statutory minimums

Small business eligibility thresholds

Businesses employing fewer than 15 people are classified as small businesses under workplace legislation. This count includes full-time, part-time, and regular casual employees, but excludes contractors and irregular casuals. For workers at these businesses, the minimum employment period extends to 12 months.

The Small Business Fair Dismissal Code provides a defence for small business owners who follow its procedures. Compliance with the code means a dismissal is deemed fair regardless of whether it would otherwise be considered harsh or unreasonable. The code requires employers to have a valid reason for dismissal, provide warnings for performance or conduct issues, and allow employees a chance to respond before termination.

Casual employee eligibility rules

Casual workers face additional requirements beyond the standard minimum employment period. They must demonstrate that their work was regular and systematic throughout the qualifying period. A recurring roster or consistent work pattern indicates the regularity needed to qualify.

Irregular, short-term, or occasional engagements do not meet this standard. Employees working under these conditions may find their claims dismissed even after completing the required time period if the nature of their engagement does not satisfy the regularity test.

Probation period considerations

Probation periods are internal employer tools typically lasting three to six months. However, these do not shorten or extend the statutory minimum employment period. Employees on probation can claim unfair dismissal once the required threshold is reached, regardless of any internal performance review processes.

Probation does not remove protections

An employee who completes six months at a business with 15 or more employees remains eligible for unfair dismissal protection even if the employer had planned a longer probation assessment.

Key eligibility checklist

Workers must be national system employees covered by a modern award, enterprise agreement, or earning below the high income threshold. As of July 2023, this threshold sat at $167,500 and is indexed annually.

How does unfair dismissal work through Fair Work in NSW?

Once eligibility is confirmed, the formal process begins with the Fair Work Commission. NSW does not maintain separate state-level unfair dismissal laws. Instead, the federal framework applies to all national system employees in the private sector, covering the majority of workers throughout the state.

Lodging an application

Claims are lodged using Form F2 through the Fair Work Commission website. The filing fee sits at approximately $83.30, though this may be waived for applicants experiencing financial hardship. The application must be submitted within 21 days of the dismissal taking effect. This deadline is calculated from the day notice expires or from the date payment in lieu of notice is received.

Extensions to this window are rarely granted and require demonstration of exceptional circumstances. Missing this deadline typically prevents further action, making timely filing critical.

Conciliation and hearing stages

After receiving an application, the Fair Work Commission arranges a conciliation conference. Approximately 90 percent of claims resolve at this stage through negotiated settlements between the parties. Conciliation is confidential and informal, designed to facilitate agreement without the need for a formal hearing.

When conciliation fails to produce a resolution, either party may request the matter proceed to a full hearing. At the hearing, the Commission assesses whether the dismissal was harsh, unjust, or unreasonable based on criteria outlined in section 387 of the Fair Work Act. Factors considered include whether the employee had a valid reason for dismissal related to capacity, conduct, or redundancy, whether they were notified of that reason, and whether they were given an opportunity to respond.

Evidence matters

Employers following the Small Business Fair Dismissal Code can submit evidence such as written warnings, meeting notes, and termination letters. Compliance with the code serves as a complete defence against unfair dismissal claims.

The Small Business Fair Dismissal Code explained

Small business owners seeking to rely on the code must be able to demonstrate adherence to its requirements. The code outlines specific steps for dismissal in different circumstances. For performance or conduct issues, employers should provide formal warnings and allow the employee a reasonable opportunity to improve before taking action.

For serious misconduct, the code permits summary dismissal without notice. Examples include theft, fraud, workplace violence, and serious occupational health and safety breaches. While a police report can strengthen the employer’s case, it is not strictly required for the code to apply.

In the matter of Jingmin Zeng v Vectus Biosystems Ltd (FWC 5536), the Commission found dismissal fair based solely on the employer’s compliance with the Small Business Fair Dismissal Code, without needing to assess whether the dismissal was harsh, unjust, or unreasonable.

Is pursuing unfair dismissal in NSW worth it?

Whether lodging a claim makes practical sense depends on several factors including the strength of the case, the availability of evidence, and the potential remedies. Employees should weigh these considerations carefully before committing to the process.

Potential outcomes and remedies

Successful claimants may receive reinstatement to their former position or compensation of up to 26 weeks’ pay. Compensation awards are capped by the high income threshold and reduced if the employee’s earnings during the redundancy period reduce the financial impact of dismissal. Reinstatement is generally preferred by the Commission as it restores the employee to their original position.

Costs and practical considerations

The filing fee for a Fair Work application is relatively modest, and self-representation is permitted throughout the conciliation stage. Many applicants navigate the process without engaging a lawyer, particularly when the facts are straightforward and well-documented.

However, complex matters involving disputes over regularity of employment, small business code compliance, or significant compensation amounts may benefit from professional legal advice. Employment lawyers with experience in unfair dismissal cases can assess the merits of a claim and advise on preparation before conciliation or hearings.

Important risks for claimants

Claims can be dismissed at an early stage if the applicant fails to meet the casual regularity test or does not satisfy the minimum employment period. Employees with borderline cases should verify their eligibility carefully before filing.

Timeline for unfair dismissal claims in NSW

The following sequence outlines the key stages from dismissal to potential resolution. Timelines can vary depending on whether conciliation succeeds or a full hearing becomes necessary.

  1. Dismissal occurs: The employment relationship ends, with or without notice or payment in lieu.
  2. Eligibility check: The employee verifies minimum employment period, business size, employment type, and income threshold.
  3. Application lodgement: Form F2 filed with the Fair Work Commission within 21 days of dismissal taking effect.
  4. Conciliation scheduled: The Commission contacts both parties and arranges a confidential conference, typically within weeks of filing.
  5. Settlement or escalation: Approximately 90 percent of cases settle at conciliation. Unresolved matters proceed to a formal hearing.
  6. Hearing and decision: The Commission member evaluates evidence and issues a written determination. Either party may appeal on legal grounds.

Background: How unfair dismissal fits within NSW workplace law

Unfair dismissal provisions were introduced nationally through the Fair Work Act 2009, harmonising what had previously been a fragmented system of state and federal protections. NSW residents employed in the private sector access these federal protections rather than any state-specific scheme, as the state referred its industrial relations powers to the Commonwealth.

Public sector employees in NSW, including those in government departments and agencies, generally fall under state-based public sector employment legislation. This distinction means most workers reading this article will be covered by the federal framework described here. For targeted information about public sector roles, separate resources are available through NSW government employment portals.

The system aims to balance employee protections with legitimate business needs. The Small Business Fair Dismissal Code reflects legislative intent to reduce compliance burdens for smaller employers while still providing meaningful protections against unjustified termination. Understanding which framework applies to your employment situation is the first step in determining your rights and options.

What sources say about unfair dismissal protections

The Fair Work Commission must consider whether the dismissal was harsh, unjust or unreasonable. The Commission is not required to find that the dismissal was unreasonable in light of the employer’s action, but rather whether the dismissal was harsh, unjust or unreasonable as a whole.

— Section 387, Fair Work Act 2009

Small business employers who comply with the Small Business Fair Dismissal Code are taken to have dismissed the employee fairly. This means the Fair Work Commission will not consider whether the dismissal was harsh, unjust or unreasonable.

— Fair Work Commission Small Business Hub

A casual employee is only eligible to make an unfair dismissal claim if they have been employed on a regular and systematic basis and had a reasonable expectation of ongoing employment.

Summary: Key points about unfair dismissal thresholds in NSW

Employees in NSW considering an unfair dismissal claim should first confirm they meet the minimum employment period, verify their business size classification, and ensure their employment type satisfies the applicable requirements. Applications must reach the Fair Work Commission within 21 days, and casual workers must demonstrate regularity of engagement throughout the qualifying period.

Small business employees may find their cases subject to the Simplified Dismissal Code, which focuses on procedural compliance rather than the broader harshness test applied to larger employers. Compensation and reinstatement remain available remedies, though outcomes depend heavily on the specific facts and evidence presented.
