The Australian Flag Society (AFS) was founded as an advocacy group to argue the case for a referendum and constitutional elevation for the existing flag of Australia.

The Australian flag debate is a question over whether the Australian flag should be changed, particularly to remove the Union Jack from the canton, but also to possibly introduce a completely new design without the Southern Cross. Acknowledgement of the significance of the issues, and corresponding changes are required to reflect Australia's multicultural society, as well as to reflect Australia's immensely rich, and intricate and complex shared history.
