The Australian flag is the blue ensign design. It is the national flag of Australia and has flown since 1901. The flag is comprised of the Union Jack in the top left corner. Directly beneath, in the lower left corner, lies the Commonwealth star, also known as the Federation star. The right side of the blue ensign design is a pattern of five white stars. This pattern is the Southern Cross. Not all of the stars in the Southern Cross have seven points. The Australian blue ensign design is the result of a contest held by the first Prime Minister, Rt Hon Sir Edmund Barton. There were 32,823 entries into the contest. Five winners shared the prize due to their almost identical designs.
An Australian flag in both the blue ensign or the red ensign designs are readily available from the reliable sellers on eBay. So, hoist a flag for Australia. Fly red on merchant ships at sea and blue on the land, as stated in the 1953 decree.
