When is the King's Birthday public holiday in Australia in 2026?
In 2026, the King's Birthday public holiday in Australia falls on Monday 8 June. This date applies to the Australian Capital Territory, New South Wales, the Northern Territory, South Australia, Tasmania and Victoria, where the holiday is set for the second Monday in June each year. The official and observed date are the same in 2026, so there is no separate “observed” day to keep track of.
Knowing that King's Birthday 2026 lands on a Monday means residents in these states and territories enjoy a long weekend. That timing is important for planning travel, work rosters and family events, as roads, accommodation and popular attractions may be busier than a standard weekend. Western Australia and Queensland mark the King's Birthday on different dates later in the year, so people moving between states should check which calendar applies to them.
Because the holiday is tied to a fixed weekday pattern rather than the monarch's actual birth date, the exact calendar date shifts slightly from year to year. In 2026 it happens to be 8 June, while in other years the King's Birthday long weekend can fall a few days earlier or later. Checking the specific date helps avoid confusion with school terms, sporting fixtures and other June commitments.
