Flag of South Australia
|Design||The flag is based on the defaced British Blue Ensign with the state badge located in the fly. The badge is a gold disc featuring a piping shrike with its wings outstretched. |
The current state flag of South Australia, was officially adopted by the government of South Australia in 1904.
The badge is believed to have been originally designed by Robert Craig, a teacher at the School of Arts in Adelaide, and officially gazetted on 14 January 1904. 
The 1904 design shows in heraldic form a local bird - what was called a Piping Shrike, a form of magpie. There has been some speculation that the stylisation of the bird was inspired by the Imperial German (and Austrian) heraldic eagle.
