There is no single national date for the Labour Day public holiday in Australia in 2026; the date is determined separately by each state and territory. Depending on where the employee works, Labour Day (also known as May Day or Eight Hours Day) falls on different dates.

For the 2025‑26 financial year (i.e., the 2026 calendar year), the dates are:

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

Because the holiday is set at different times in different parts of the country, it would be incorrect to give one date that applies everywhere. Employers and employees must check the specific public holiday calendar for their state or territory.
