The flag of Western Australia was officially adopted on 31 December 1953, but it had been used unofficially for many years before that. It was designed by a committee that included the state's governor, Sir James Mitchell, and the state's premier, David Brand. The committee held a competition to design the flag, and the winning entry was submitted by a 16-year-old schoolgirl named Jenny Forward.
The flag of Western Australia is one of the most distinctive flags in Australia. It is flown on all state government buildings and is also used by many businesses and organisations in the state. The flag is a symbol of Western Australia's identity and heritage, and it is a source of pride for many Western Australians.
