There is no single national Labour Day date in Australia in 2026. Labour Day (called Eight Hours Day or May Day in some places) is a public holiday set independently by each state and territory, so the date depends entirely on where the employee works. A single confident national date would be wrong.

The 2026 dates, by jurisdiction:

- Western Australia: Monday 2 March 2026 (first Monday in March)
- Victoria: Monday 9 March 2026 (second Monday in March)
- Tasmania: Monday 9 March 2026 (called Eight Hours Day, second Monday in March)
- Queensland: Monday 4 May 2026 (first Monday in May)
- Northern Territory: Monday 4 May 2026 (called May Day, first Monday in May)
- New South Wales: Monday 5 October 2026 (first Monday in October)
- Australian Capital Territory: Monday 5 October 2026 (first Monday in October)
- South Australia: Monday 5 October 2026 (first Monday in October)

For payroll, the correct date to apply is determined by the state or territory in which each employee works, not by a national rule.
