The obverse shows the crowned mature head offacing right (her effigy known as the”Fourth Portrait”). The Queen wears the “Girls of Great Britain and Ireland” diamond tiara, a wedding gift from Queen Mary (Her Majesty’s grandmother) in 1947 – which she also has on the Machin and the Gottwald portraits.
The reverse design includes a representation of the head and shoulders of a traditional Australian Aboriginal (half-length figure of Aboriginal male, bare-chested, facing three-quarters right), a representation of the Southern Cross and a representation of Australian flora.
