The coat of arms of Australia is the formal symbol of the Commonwealth of Australia and its monarch, currently Queen Elizabeth II. The first arms were authorised by King Edward VII on 7 May 1908, and the current version by King George V on 19 September 1912.

The Red Kangaroo and Emu that support the shield have never been designated as official animal emblems of the nation. They owe their unofficial recognition to the fact that they are native Australian fauna (found only on that continent), and likely chosen because they are the most well-known native Australian animals large enough to be positioned together in scale holding up the shield.
