There is no single national date for "Labour Day" in Australia in 2026. Labour Day (and its equivalents) is a state and territory public holiday, not a national one, and each jurisdiction sets its own date under its own holiday-related legislation. The correct date for any given employee depends entirely on the state or territory in which that employee works, not on a single Australia-wide calendar entry. A payroll officer should look up the holiday by the employee's work location, not assume one date applies everywhere.

For FY2025-26, the 2026 dates are:

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

So the same holiday name maps to three different dates across the country in 2026 (2 March, 9 March, 4 May, or 5 October, depending on state/territory), and in WA, Victoria and Tasmania the date even differs from one another despite all falling in March. There is no single confident "the date" answer that holds nationally - confirm the employee's state/territory of work first, then apply that jurisdiction's gazetted date.
