Wrong Form on Day 21: Why the FWC Refused a Three-Day Extension, and How the 21-Day Rule Really Works

A worker's employment with residential care provider Hypar Group Pty Ltd ended on 26 June 2026. On the 21st and final day of the filing window she lodged a Form F9, the application for unlawful termination. On 20 July 2026 the Commission contacted her to say the wrong form had been completed, and she filed an unfair dismissal application the same day, three days out of time. Commissioner Spencer refused to extend time and dismissed the application on 15 September 2026 in [2026] FWC 3524 (report of the decision).

It was not an isolated result. In the same week the Commission dismissed an unfair dismissal claim against EnergyAustralia filed seven days late and refused an extension for a claim against Lendlease filed 25 weeks late. Late claims fail far more often than they succeed.

Under section 394(2) of the Fair Work Act an unfair dismissal application must be lodged within 21 days after the dismissal took effect. The Commission can allow a further period under section 394(3) only if it is satisfied there are exceptional circumstances, taking into account six things:

• the reason for the delay
• whether the person first became aware of the dismissal after it took effect
• any action the person took to dispute the dismissal
• prejudice to the employer, including from the delay
• the merits of the application
• fairness between the person and other people in a similar position

The worker argued that she had acted within time to dispute the dismissal, that the wrong form was a genuine mistake, that the delay was only a few days, that she moved promptly once told, and that the employer suffered no prejudice. The employer opposed any extension.

Reason for the delay weighed against her. The Form F9 explains that it is for terminations alleged to be for unlawful reasons under section 772 and directs applicants to the Commission's material on the different types of dismissal claim. The Commissioner also noted that general information could have been obtained by phoning the Commission.

Filing the wrong type of claim in the same tribunal is not the same as filing in the wrong tribunal. The Commissioner distinguished a 2009 case, Palmer v RCR Engineering, where an applicant had lodged in time with the Western Australian commission before filing federally and got an extension. Here both applications went to the same body, and the application type had "fundamentally" changed. The Commissioner applied the Full Bench's reasoning in Ioannou v Northern Belting Services that an unfair dismissal application under section 394 is "fundamentally different" from a general protections application under section 365, even where both arise from the same dismissal.

The first application had not been served on the employer, so it did not tell the employer the dismissal was being disputed. What was eventually served was the late unfair dismissal claim. There was no delay in the worker learning of the dismissal. Prejudice and fairness were neutral. On the merits, the employer raised a separate hurdle, that she was a casual who had not worked a shift since October 2025 and so may not have been employed on a regular and systematic basis, which the Commissioner called "problematic for the Applicant" while declining to decide it.

The Commissioner's summary: "the granting of an extension of time is a high bar; and the statutory time limit of 21 days is set to provide certainty."

• Count 21 days from the day the dismissal took effect, not from the day you were told or the day you got your final pay. If your employment ended on a Friday, day 21 is three weeks later. Lodge earlier than that.
• Pick the right application. Unfair dismissal is Form F2 (section 394). General protections involving dismissal is Form F8 (section 365) and also carries a 21-day limit. Unlawful termination (Form F9, section 772) is for people who cannot bring the other two. Our which-claim triage sorts this in a few questions, and the unfair dismissal checker confirms eligibility, including the six-month minimum employment period and the regular-and-systematic test for casuals.
• Serve the employer. The Commission sends your application to the employer once it is lodged, but an application that never reaches them will not count as disputing the dismissal.
• If you are already late, lodge anyway and explain. Extensions are rare, not impossible; the six factors above are what you need to address. The Fair Work Ombudsman's unfair dismissal page sets out the basics, and the guides on our legal help hub cover when a lawyer is worth the cost.
