There is no single national date for the Labour Day public holiday in Australia. Public holidays are determined separately by each state and territory government, not at a federal level, so the date depends entirely on where the employee works. A single confident national date would be incorrect and should not be used for payroll.

In 2026 the relevant public holiday falls on these dates by jurisdiction:

- Western Australia: Monday 2 March 2026 (Labour Day)
- Victoria: Monday 9 March 2026 (Labour Day)
- Tasmania: Monday 9 March 2026 (Eight Hour Day)
- Queensland: Monday 4 May 2026 (Labour Day)
- Northern Territory: Monday 4 May 2026 (May Day)
- New South Wales: Monday 5 October 2026 (Labour Day)
- Australian Capital Territory: Monday 5 October 2026 (Labour Day)
- South Australia: Monday 5 October 2026 (Labour Day)

Confirm the employee's work location before applying any date.
