The flag of Australia has a blue background, with the Union Jack in the canton, a white seven-pointed star below the Union Jack, called the "Commonwealth Star", and a representation of Crux in the fly half of the flag, in white seven-pointed stars, but the star representing ε (Epsilon) Crucis is a five-pointed star.


The inclusion of the entire UK flag represents the history Australia has with the British. Below it is the Commonwealth Star, uniting it with the other British colonies, who now share a monarch. The Southern cross is one of the most visible constellations in the Southern Hemisphere and it has represented Australia since the early days of British settlement. The four main stars also symbolize justice, prudence, temperance and fortitude.
