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. 19 October 2030 carries this public holiday in those three states, with every other state and territory working through an ordinary day.
Sport fixtures, markets and family events across Australia are concentrated on Saturdays more than any other day of the week. 19 October 2030 falls on Saturday, outside the standard working-day count used on this page, between the working week that ends on Friday and the one that begins the following Monday.
The quarter containing 19 October 2030 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.
