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. 15 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.
Friday 15 October 2027 is the last working day of the standard Monday-to-Friday week, the fifth and final working day before the weekend begins. A public holiday landing on this day of the week joins directly onto the Saturday and Sunday that follow it, forming a three-day weekend without using any annual leave.
A public holiday that falls on a Monday or a Friday produces a three-day weekend without using any annual leave, which is why long-weekend planning around 15 October 2027 depends on which day of the week the nearest public holiday falls on. A midweek holiday delivers no such automatic extension, though many workers bridge it with a single day of leave.
