You have 21 calendar days from the date your dismissal takes effect to lodge an unfair dismissal application. Weekends and public holidays count. The deadline is strictly enforced — extensions are only granted in exceptional circumstances. If you're unsure, read this first, then act.
- Most SA private sector workers fall under the national Fair Work system — your claim goes to the Fair Work Commission, not SAET.
- You have exactly 21 calendar days from the date your dismissal takes effect. The clock starts the day after dismissal.
- Weekends and public holidays during the 21 days do not pause the clock — only if the 21st day itself falls on one.
- Missing the deadline by even one day — or in one recent case, 4 seconds — resulted in the claim being dismissed with no extension granted.
- ChatGPT and generic AI tools have failed to flag this deadline in documented cases. Do not rely on them.
How the 21 days work in South Australia
Most South Australian employees in the private sector fall under the national Fair Work system following SA's referral of industrial powers to the Commonwealth. That means your claim goes to the Fair Work Commission — not the South Australian Employment Tribunal (SAET), which handles SA public sector workers under state law.
The rules under the Fair Work Act are strict and apply nationally:
- The 21 days start the day after your dismissal takes effect — the day of dismissal itself is not counted
- Your dismissal "takes effect" on the last day of your employment — which may be later than the last day you physically worked if you're on a notice period being paid out
- If the 21st day falls on a weekend or public holiday, you have until the next business day
- Weekends and public holidays during the 21-day window do not extend the deadline
- The Commission counts the date it receives your application — not the date you sent it
If your employer terminated your contract on 1 July but gave you two weeks' notice ending 15 July, your dismissal takes effect on 15 July — not 1 July. The 21-day clock starts on 16 July. If they paid out your notice rather than requiring you to work it, the dismissal generally takes effect on the last day you worked. If you are unsure which date applies to you, assume the earlier date and act immediately.
What happens if you miss it
The Fair Work Commission can grant an extension — but only where there are "exceptional circumstances." The bar is high, the Commission's own decisions describe it as a high bar, and it is getting harder to clear.
In 2025, the Commission refused to extend time after an application was filed just 4 seconds late. The applicant knew the deadline. The Commission found no exceptional circumstances and dismissed the claim.
In a separate case, an applicant relied on ChatGPT for guidance on their dismissal. ChatGPT failed to flag the 21-day requirement. The applicant filed their claim two and a half years late. The Commission dismissed the application and the presiding Deputy President stated the case highlighted "the obvious danger of relying on artificial intelligence for legal advice."
What does not count as exceptional circumstances:
- Not knowing about the deadline
- Being too distressed or unwell to act — unless a serious medical condition is formally documented
- Waiting to see whether the situation would resolve directly with your employer
- Relying on incorrect information from AI tools, online searches, or informal advice
- Your representative missing the deadline — you share responsibility for their actions
Are you eligible to claim in SA?
Before you file, check that you meet the basic eligibility requirements under the Fair Work Act:
You may be eligible if you
- Worked for the employer at least 6 months (12 months for small businesses under 15 staff)
- Earn below $183,100 in 2025–26, or are covered by an award or enterprise agreement
- Are a national system employee — most SA private sector workers are
- Were dismissed — not made redundant through a genuine redundancy
- Are a casual with regular and systematic employment and a reasonable expectation of ongoing work
You are generally not eligible if you
- Are still within your minimum employment period
- Earn above the high income threshold and are not covered by an award
- Were made genuinely redundant with proper consultation
- Resigned — unless you were forced to (constructive dismissal)
- Are an SA public sector worker — SAET applies, not FWC
What "unfair dismissal" actually means
Not every dismissal is unfair in the legal sense. The Fair Work Commission assesses whether the dismissal was harsh, unjust, or unreasonable — and your employer only needs to fail on one of the three for a claim to succeed.
The Commission considers: whether there was a valid reason for the dismissal; whether you were told why and given a chance to respond; whether the process was consistent with how others have been treated; and whether the outcome was proportionate to the conduct alleged.
Being let go without prior warnings, being dismissed on a reason that doesn't hold up to scrutiny, or being treated differently to colleagues in similar situations are the circumstances that tend to succeed. Dismissals following a complaint, an injury, or a request for entitlements attract additional scrutiny.
What to do right now — step by step
Confirm the exact date your dismissal took effect
This is the date your employment ended — not when you were told, not when you cleaned out your desk. If you served a notice period, it is the last day of that period.
Count forward 21 calendar days
Start from the day after dismissal. Count every day including weekends and public holidays. Mark that date clearly. That is your hard deadline.
Check your eligibility
Minimum employment period, income threshold, employment type. If you are unsure, assume you are eligible and act — you can clarify later. Missing the deadline while checking eligibility is not recoverable.
Lodge your application at fwc.gov.au using Form F2
You can file online. The fee is $83.30 for 2025–26 — a waiver is available if you hold a concession card or would face financial hardship. File first, negotiate later.
Get advice — even briefly — before the deadline
You do not need a lawyer to lodge the form. But a short consultation before you file is worth it. Most claims resolve at conciliation — having a clear picture of your position matters.
The bottom line: The strength of your case, the length of your service, and the unfairness of what happened to you will not save a claim that was filed late. The Commission has dismissed applications filed 4 seconds after the deadline. Act first. Understand your position fully once the form is lodged.
