Flag - Australian Red Ensign

The Australian Red Ensign is a red version of the National flag, featuring three main elements on a red background:
(1) the red, white and blue Union Jack in the canton (upper left corner);
(2) a large white seven-pointed Commonwealth Star beneath it; and
(3) the Southern Cross constellation on the fly (right-hand side) in white.
The Southern Cross consists of five stars: four seven-pointed stars and one five-pointed star, mirroring the design of the National flag but set against a red field instead of blue. The red color follows the British Red Ensign tradition, historically denoting merchant shipping.
