The national flag of Australia is based on the British Blue Ensign—a blue field with the Union Jack in the upper hoist quarter—featuring a large white seven-pointed star (the Commonwealth Star) and a representation of the Southern Cross constellation, made up of five white stars (one small five-pointed star and four larger seven-pointed stars). Australia also has a number of other official flags representing its states and territories, indigenous peoples and government bodies. It is one of the most distinctive constellations visible in the Southern Hemisphere, and has been used to represent Australia since the early days of British settlement. The flag was last altered in 1908 to its current form when a seventh point was added to the Commonwealth Star; this seventh point has come to represent all territories and any future states of Australia.
