King's Birthday 2027

Type of holiday: statutory public holiday, a non-working day.

The King's Birthday public holiday, observed on the second Monday in June across most of Australia, has nothing to do with the monarch's actual date of birth. It is a long-standing constitutional tradition, a day set aside each year to formally mark the sovereign's official birthday regardless of when they were born.

A tradition dating back to King George V

The practice of celebrating an official royal birthday on a convenient date, separate from the monarch's real birthday, was established in Australia during the reign of King George V, whose actual birthday fell in an inconvenient part of the calendar for outdoor celebrations. Choosing a fixed date in the cooler months allowed governments to guarantee reliable weather for parades, gun salutes and community events, and the practice has simply continued through subsequent monarchs, with the title updated to reflect whoever currently holds the throne.

How the day is marked

Official observances include the Queen's (now King's) Birthday Honours lists, announced around this time to recognise Australians for service to the community, along with any formal vice-regal or ceremonial events at state level. For most people, though, the day is simply a mid-year long weekend: a chance for a short getaway, sport, or catching up on jobs around the house while the year's second half gets underway.

Where it's a public holiday

The second-Monday-in-June date applies almost everywhere in the country, but two states break from it entirely:

• New South Wales, Victoria, South Australia, Tasmania, the Australian Capital Territory and the Northern Territory — observed on the second Monday in June
• Queensland — does not use this date; the King's Birthday is instead held in early October
• Western Australia — does not use this date either; its King's Birthday holiday falls later, in September or October, on a date announced annually

Why Queensland and Western Australia go their own way

Queensland shifted its King's Birthday holiday to October decades ago, spacing it away from other mid-year holidays and giving the state a public holiday later in the year when the calendar would otherwise run for months without one. Western Australia took a similar approach but without settling on a fixed formula: instead, the state's Governor proclaims the exact date each year, which is why the Western Australian King's Birthday cannot simply be calculated in advance the way the June date can elsewhere.

Substitute days

Since the holiday is defined by reference to a particular Monday rather than a calendar date, it always lands on a Monday in every state that observes the June version, so no substitute-day arrangement is needed for it specifically.

What to expect on the day

Government offices, schools and banks close in every state observing the holiday on their respective date. Retail trading hours vary by state and by individual business, with many shopping strips open in some form and others closed entirely; public transport typically shifts to a holiday or Sunday timetable. Anyone dealing with Queensland or Western Australia in June should note that it is an ordinary working day in those two states.
