Australian National Flag Day is observed in Australia every September 3. This date commemorates the first flying of the Australian National Flag in 1901, when then Prime Minister Edmund Barton announced the winning design in a competition. The flag was first displayed over the dome of the Royal Exhibition Building in Melbourne. The celebration of this day was proposed by John Christian Vaughan in 1984, leading to public ceremonies, including one in Hyde Park, Sydney. The observance gained popularity, with notable events such as a Flag Day address by the Governor of New South Wales in 1989 and an official ceremony in Martin Place Amphitheater in 1996. Annual ceremonies are now held in schools and major centers across the country, although it is not a public holiday.
