If you have been dismissed in Australia, you have 21 calendar days to lodge an unfair dismissal application with the Fair Work Commission (FWC). The clock starts the day after your dismissal takes effect, and the FWC states that the day of dismissal itself does not count. Weekends and public holidays are counted too, so the real working window is shorter than it looks.
This guide shows how to count the 21 days, what changes if your last day differs from the day you were told, when the Commission will accept a late application, and what to do in the first week.
TL;DR
- You have 21 calendar days from the day your dismissal takes effect, counting from the following day.
- Lodge online: electronic applications can be filed 24/7, but do not plan to use the last day.
- Late applications are only accepted in exceptional circumstances, and an extension is never automatic.
- Check eligibility early: minimum employment period, coverage and the high income threshold all matter.
- If your dismissal involves discrimination or a workplace right, a general protections claim may fit better, and it has its own 21-day limit.

How the 21 days are counted
The Fair Work Commission says an application must be lodged within 21 days after the dismissal takes effect. It uses calendar days, not business days. Every Saturday, Sunday and public holiday uses up one of your days.
A worked example. You are told on Monday 5 October 2026 that your employment ends that day. Day one is Tuesday 6 October. Day 21 is Monday 26 October 2026. An application lodged on 27 October is late, even by a single day.
The FWC says that if the final day falls on a weekend or public holiday when the Commission is closed, the deadline moves to the next business day. Because online lodgement runs around the clock, treat that as a safety net only. The sensible target is to lodge in the first week or two.
When does the dismissal "take effect"?
This is where people lose days. The date that counts is not always the date of the termination letter.
| Situation | Usually when the 21 days start counting |
|---|---|
| Dismissed immediately, with pay in lieu of notice | The day after the day you were told you were out |
| Given notice and required to work it | The day after your last day of employment |
| Termination letter dated in advance | The day after the date the employment actually ends |
| Resignation you say was forced | The day after the resignation took effect |
The table is a guide, not a ruling. Dates can be disputed, particularly where an employer says you resigned. If you are unsure, count from the earliest possible date and lodge on that basis. A lodgement made too early costs you nothing, while one made too late may cost you the claim.
Forced resignations and disputed dismissals
If you were pushed into resigning, you may still be able to claim, but you must show the resignation was in substance a dismissal. The same 21 days apply, and they run from the day your resignation took effect, not from the day the conduct began. We cover this scenario in our guide to constructive dismissal and the 21-day deadline.
If your employer says you resigned and you believe you were dismissed, do not wait for the dispute to settle. Lodge within 21 days of the date you say your employment ended, and let the Commission decide the facts.
What if you miss the deadline?
The Commission can allow a further period, but only in limited cases. Section 394(2) of the Act sets the 21 days or such further period as the Commission allows. The FWC explains that it may allow more time only in exceptional circumstances.
The FWC also warns that an extension is not a foregone conclusion. In practice the Commission looks at:
- The reason for the delay. An acceptable explanation for the whole delay is often the most important factor against an applicant when it is missing.
- Prejudice to the employer. For example, whether evidence or witnesses have been lost.
- The merits of your case. A strong claim helps, but does not rescue an unexplained delay.
- Fairness to others in similar positions. The Commission aims to treat like cases alike.
Exceptional circumstances do not have to be rare events. According to the Commission's own decisions, a combination of ordinary factors can add up to exceptional circumstances. Even so, law firm commentary on 2025 decisions shows that employers regularly challenge late filings, and they often succeed.
If you are already out of time, lodge anyway and include a clear statement of why you were late, day by day if you can. Illness, hospitalisation, misleading advice from an official body or a genuine mistake about the date can all be raised, but you will need evidence for each. Do not assume that being unaware of the rule will be enough. See a community legal centre, union or employment lawyer quickly.
Check eligibility before you lodge
The deadline is only half the picture. Even a perfectly timed application fails if you are not eligible. Under the FWC's overview, you generally must have completed:
- 6 months of employment with an employer of 15 or more employees, or
- 1 year with a small business employer (fewer than 15 employees).
Casual employees are generally only counted if their work was regular and systematic. Our guides on the minimum employment period and on casual employees and unfair dismissal go through the detail. If you were dismissed during probation, the same minimum period still applies, as set out in our probation checklist.
You also need to be covered by the national system and either be under the high income threshold, or be covered by an award or enterprise agreement. From 1 July 2026 the compensation cap is $95,050, which rose with the new threshold. Our article on the high income threshold explains how it can block a claim.
If you are also a small business owner who has been named in a claim, the same dates matter to you. The date the application was lodged is on the notice you receive, and it decides whether you can raise a time objection.
Unfair dismissal or general protections?
These are two separate pathways. Unfair dismissal asks whether the dismissal was harsh, unjust or unreasonable. A general protections claim asks whether you were dismissed because of a protected workplace right, or because of something like discrimination.
Practitioners often point out that if your case involves discrimination or whistleblowing, a general protections claim may fit better, as the FWC's unfair dismissal page separates the two pathways. The Norton Rose Fulbright article above also notes that general protections dismissal claims face a 21-day limit as well. So the timing pressure does not go away by switching pathways.
For a closer look, read our general protections claim checklist and our piece on dismissal after whistleblowing. If you are not sure which path applies, preserve both options by acting within the 21 days, then get advice on which application to file.
Our perspective: why we tell people to start on day one
We built Terminationhelp around Australian Fair Work procedure only, and the same pattern shows up in the questions people bring to a preparation tool like ours. Most people do not miss the deadline because they were careless. They lose days because they are in shock, they hope the employer will reverse the decision, they wait for a final pay slip, or they are unsure whether they are eligible.
The 21 days are the one fixed point in a claim that otherwise has a lot of grey. So we suggest a simple order of work:
- Write down the exact date and time you were told, and the date your employment ended.
- Count 21 calendar days from the next day, and put the last day in your calendar with a reminder a week earlier.
- Gather the termination letter, contract, pay slips, performance records and messages while they are still accessible.
- Check your eligibility and which employer size applies.
- Lodge, then refine. Preparing a clean, accurate application takes time, so begin immediately.
We also think nobody should rely on an extension. It is a safety valve for exceptional cases, not a plan. A tool can help you assemble forms and evidence quickly, but it does not replace advice from a lawyer, union or community legal centre when your case is complicated.

Preparing your application without losing days
Our preparation support walks you through an unfair dismissal matter step by step: an eligibility check, a timeline built from your dates, evidence organisation and the generation of the Fair Work forms you need. Everything is grounded in Australian legislation and Fair Work Commission procedure. You can then file independently or take the finished packet to a lawyer, union or community legal centre. You can start from our homepage at any point in the 21 days.
What happens after you lodge
Lodging the application stops the time limit issue, but it starts a process. The employer responds, and the Commission usually arranges a conciliation or conference, which is a chance to settle. If the matter is not resolved, it can proceed to a hearing.
If you succeed, the Commission can order reinstatement or compensation. The FWC's page on outcomes at a hearing reports that compensation is far more common than reinstatement among granted applications in 2024-25. Compensation covers economic loss only, not distress or humiliation, and is limited by the cap, which is the lesser of 26 weeks of your pay or half the high income threshold. For more, see our overview of unfair dismissal remedies.
Common timing mistakes
- Waiting for an internal appeal. An internal review or complaint does not pause the 21 days.
- Counting from the wrong date. Counting from the letter date instead of the end of employment can cost or save days. Check both.
- Counting business days. The limit is calendar days.
- Leaving it for the last evening. Technical problems, missing documents or a wrong form can push you out of time.
- Assuming a lawyer will chase it. If you have booked an appointment, lodge or confirm the lodgement date in writing yourself.
- Mixing up other time limits. Other states' systems and other countries have different rules. For instance, the UK's tribunal time limits quoted on the GOV.UK site do not apply here. If you work in a state system, such as South Australia's tribunal, check that body's rules.
Frequently asked questions
Does the 21-day limit include weekends?
Yes. It is 21 calendar days, so weekends and public holidays count. The FWC says that if the last day falls on a day the Commission is closed, the deadline moves to the next business day, but you should not plan around that.
Can I lodge an unfair dismissal claim after 21 days?
Sometimes, but only if the Commission finds exceptional circumstances. You will need to explain the whole delay with evidence, and the employer can oppose it. The safest approach is to lodge within the 21 days.
Does the time limit apply if I was forced to resign?
Yes. If you say you were forced to resign, the same 21 days apply, counted from the day after your resignation took effect. You will also need to show the resignation was not truly your choice.
Is the time limit the same for general protections claims?
The 21-day limit also applies to general protections claims involving dismissal. The legal tests are different, so get advice on which application suits your facts, and do not let the decision use up your window.
