Labour Day falls on the first Monday of March in Western Australia and on the second Monday of March in Victoria and Tasmania. New South Wales, Queensland, South Australia, the Northern Territory and the ACT do not hold a Labour Day public holiday in March at all, so the long weekend applies only in the three states that observe it on these dates.
The Ekka public holiday in greater Brisbane is held on a Wednesday during the Royal Queensland Show each August, one of the few recurring public holidays fixed to this day of the week. Wednesday 17 March 2027 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
The quarter containing 17 March 2027 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
