Labour Day falls on the first Monday of October in New South Wales, South Australia and the ACT, the only three jurisdictions observing the holiday on this date. 1 October 2026 carries this public holiday in those three states, with every other state and territory working through an ordinary day.
Workplaces commonly schedule their heaviest meeting load on Thursday, leaving Friday clearer for closing out the week's remaining work. 1 October 2026 falls on this day, the fourth working day of its standard Monday-to-Friday week, with one working day remaining before the weekend begins and the count above resets for Monday.
The quarter containing 1 October 2026 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.
