King's Birthday falls on the second Monday of June in New South Wales, Victoria, South Australia, Tasmania, the Northern Territory and the ACT. Western Australia and Queensland do not observe the holiday on this date, so 11 June 2027 carries the public holiday in six jurisdictions and not in the other two, one of the clearest state-by-state splits on the calendar.
Traffic volumes, flight bookings and getaway trips peak on Friday afternoons across Australian cities as the working week ends. Friday 11 June 2027 falls on this day of the week, at the close of its standard five-day working stretch, marking the start of the weekend for the standard Monday-to-Friday workforce.
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 11 June. Interstate businesses need to check more than one state's list before setting a national deadline.
