The first Commonwealth Coat of Arms was introduced on 7 May 1908. The current Coat of Arms was introduced on 19 September 1912.
History of the Commonwealth Coat of Arms
The first official coat of arms of Australia was commissioned in 1908, seven years after the federation. It consisted of a shield held by the Australian Coat of Arms animals (the kangaroo and the emu) on a bed of green grass, with the motto “Advance Australia” written underneath.
In 1912, the coat of arms underwent a redesign, with the animals in particular made to look more realistic. Some people argued against having the emu and kangaroo on the emblem altogether, saying that they weren’t fitting with the heraldic theme.
