Planning Annual Leave Around King's Birthday
The King's Birthday is a Monday public holiday in most states and territories, so it delivers a ready-made three-day long weekend with no leave at all — and one or two extra days extend it comfortably.
The catch is timing: most states observe it in June, but Queensland holds it in October and Western Australia in late September, so the King's Birthday long weekend happens on different dates around the country.
