September 3 is Australian National Flag Day
PRIME MINISTER OF AUSTRALIA
The Australian National Flag consists of three parts set on a blue field. The first part is the Union Jack, acknowledging the historical link with Britain. The second part is the Southern Cross (a constellation of stars only visible in the Southern Hemisphere), representing Australia's geographical location in the world. Finally, the Commonwealth Star represents Australia's federal system of government. Originally, the Commonwealth Star had six points (for the six states), but in 1908 a seventh point was added to represent the Territories of the Commonwealth of Australia.
