The 21-day deadline for an unfair dismissal or general protections claim
Both an unfair dismissal application and a general protections dismissal application must be lodged within 21 days of the dismissal taking effect. The Fair Work Commission's own guidance treats extensions as the exception, not the rule.
An unfair dismissal application must be lodged with the Fair Work Commission within 21 days after the dismissal takes effect. A general protections dismissal application carries the same 21-day deadline. The Commission counts the 21 days starting the day after the dismissal took effect, and if the final day falls on a weekend or a public holiday when the Commission is closed, the deadline rolls forward to the next business day. A weekend or holiday that falls inside the 21 days does not pause the count.
Extensions are not routine
The Commission may allow a later application, but only where it is satisfied there were exceptional circumstances for the delay. Its own guidance is explicit about what that standard means in practice: "Exceptional circumstances are NOT regularly, routinely or normally encountered." The Commission weighs six things when an extension is requested: the reason for the delay, whether the person only learned of the dismissal after it took effect, any action the person took to dispute the dismissal, prejudice to the employer, the merits of the application, and fairness against other people in similar positions. A long delay itself works against the applicant: the Commission's guidance states that "a long delay gives rise to a general presumption of prejudice" against the person who caused it.
One line in the Commission's own guidance is worth reading twice, because it closes off the most common assumption people bring to this deadline: "Ignorance of the timeframe for lodgment is not an exceptional circumstance." Not knowing the 21-day rule existed is not, by itself, a reason the Commission will accept.
General protections: the same clock, and a published extension-refusal rate
A general protections dismissal application is governed by its own 21-day rule under a separate section of the Act, but the Commission applies the same exceptional-circumstances standard to a late application. Its own guidance states plainly that this is "a strict time limit under the law" and that "late applications are generally not accepted," adding that while an extension can be requested, "most (about 80%) are denied."
What this means in practice
There is no soft version of this deadline. If you are still deciding whether to lodge an unfair dismissal claim, a general protections claim, or both, the 21 days runs regardless of that decision. Working out eligibility, gathering evidence and choosing between the two claim types are all things worth doing quickly, inside the window, rather than after it closes.
