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 27 June 2026 carries the public holiday in six jurisdictions and not in the other two, one of the clearest state-by-state splits on the calendar.
A public holiday that falls on a Saturday sits inside the weekend rather than beside it, so it does not automatically create a substitute day off during the working week; whether one applies depends on the specific holiday and the state. Saturday 27 June 2026 falls on this day of the week, inside the weekend itself.
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 27 June 2026 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.
