When is King's Birthday 2026 in Western Australia and what day is it on?
In Western Australia, the King's Birthday public holiday in 2026 falls on Monday 28 September. It is observed on the same date it is officially scheduled, so there is no separate “observed” day or substitute day that year. The Monday timing creates a three‑day long weekend for many people who work regular Monday to Friday hours.
The King's Birthday in Australia is not tied to the monarch’s actual date of birth, and each state chooses its own observance date. Western Australia typically schedules the King’s Birthday later in the year, often in September or October, and 2026 is no exception. This later date spreads public holidays more evenly through the calendar for Western Australian residents and businesses.
Because the 2026 King's Birthday in Western Australia is on a Monday, people often plan short trips, family gatherings, or catch‑up days for errands. Public transport, retail trading, and event schedules may follow different patterns from a normal Monday, so checking specific timetables and opening hours before 28 September 2026 can help avoid surprises.
