A silver coin (28 mm diameter with milled edge) featuring on the obverse a laureate bust of Elizabeth II facing right; around, ELIZABETH II . DEI . GRATIA . REGINA +
The reverse is based on the arms of the Commonwealth of Australia, as authorised by Royal Warrant 19 September 1912 - composed of a shield divided into six parts, each containing a representation of the badge of a State (although that of South Australia is depicted as three sheaves of wheat above a rising sun instead of the authorised Piping Shrike). The shield is supported by a kangaroo and an emu standing on a grassy mound accompanied by small branches of wattle. Above the shield is a crown instead of the Federation star.
Around above, FLORIN between two seven pointed stars; and below, in the exergue, the date, 1954 curved below which, AUSTRALIA. The artist's initials KG are in the field above the back of the emu.
