King's Birthday

The King's Birthday is an official public holiday in Australia celebrating the birthday of the reigning monarch, King Charles III. Although the King was born on 14 November, Australia observes the occasion on a designated Monday rather than on his actual birthday. In 2026, most Australian states and territories will mark the King's Birthday on Monday, 8 June; Western Australia observes it on Monday, 28 September, while Queensland observes it on Monday, 5 October. These regional differences reflect the states’ separate public-holiday calendars.

The tradition developed from British imperial birthday observances held in Australia during the nineteenth century, particularly celebrations associated with Queen Victoria. Over time, the holiday became less a personal royal celebration and more a constitutional and civic occasion acknowledging Australia’s relationship with the Crown. It was known as the Queen’s Birthday during the reign of Queen Elizabeth II and was renamed the King’s Birthday after Charles III became monarch in 2022, with the new title adopted for Australian public holidays from 2023. The holiday also coincides with the announcement or presentation of Australian honours and awards, recognizing significant contributions to public life, community service, and national culture.

The Australian King’s Birthday is usually experienced as a long weekend rather than through one nationwide ceremony. Government buildings, schools, and many businesses close, while communities hold civic receptions, official ceremonies, citizenship events, and local gatherings. Honours recipients may be publicly acknowledged, and royal or military traditions can appear at formal events, although Australia’s celebrations are generally more modest than the United Kingdom’s ceremonial observances.

Australians commonly spend the long weekend visiting family and friends, taking short regional trips, enjoying picnics and barbecues, or attending winter sporting events. The King's Birthday weekend is strongly associated with Australian rules football, including the traditional AFL match between Collingwood and Melbourne at the Melbourne Cricket Ground in Victoria. Seasonal foods such as grilled meats, pies, baked dishes, and warming desserts are popular at informal gatherings. A standard greeting is “Happy King’s Birthday,” although many people simply refer to it as the “King’s Birthday long weekend.”
