Daylight saving returns on the first Sunday of October in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks forward an hour. 5 October 2027 falls in this month of change, while Queensland, Western Australia and the Northern Territory keep the same clock they run all year, unaffected by the switch.
Tuesday 5 October 2027 is an ordinary working day in the standard Monday-to-Friday week, sitting in the first half of its week and counting toward the working-day total shown above. It follows the return-to-work adjustment of Monday and precedes the midweek point that Wednesday marks in most Australian workplaces running a standard five-day schedule.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2027 can show a different total depending on which state's calendar applies to 5 October. Interstate businesses need to check more than one state's list before setting a national deadline.
