The flag was first flown in 1901. Until this time, Australia used Britain’s flag.
The Union Jack represents Australian membership of the British Commonwealth.
Beneath the Union Jack is a large white star with seven points. They represent the six states and the territories. Originally this star had six points. The seventh point, is for the territories added in 1908.
On the right hand side are the stars of the Southern Cross. The Southern Cross was chosen because it can always be seen in the Australian sky at night.
The original 1901 design depicted the stars with a differing number of points to signify their brightness. It is the only flag to fly over an entire continent.
It colours – Blue – vigilance, truth and loyalty, perseverance & justice White – peace and honesty Red – hardiness, bravery, strength & valour
