How many years has the Australian flag bean around?

Answer 1

It has been around for about a century, but the present "blue ensign" has only been the official Australian flag since 1954. In World War I Australian soldiers were usually placed in units under British command, so they fought under the Union Jack. In World War 2 there were three flags around -- the blue ensign, the red ensign, and a white ensign (on which the stars were coloured blue). Most Australians fought under the red ensign, a flag like the present flag, but with a red background for the stars instead of a blue.
