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. 16 October 2028 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.
Monday 16 October 2028 is an ordinary working day for the standard Monday-to-Friday workforce and counts toward the working-day total shown above, along with the four days that follow it through to Friday, separate from the shift rosters that retail, hospitality, healthcare and emergency services run on their own patterns.
The quarter containing 16 October 2028 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.
