In 1982 the British Royal Mint invited 17 artists to submit portrait models to be considered as a replacement for the?Machin?portrait. The Royal Mint Advisory Committee on the Design of Coins, Medals, Seals and Decorations considered 38 models. The Committee selected a group of models by Raphael?Maklouf?as most promising.
A revised model was recommended by the Committee, and accepted by the Queen for use on circulating United Kingdom coinage from 1 January 1985. Although it is not mandatory for Australia to use the same portrait as the United Kingdom uses, it was decided that the?Maklouf?effigy would be adopted on Australia's coinage from 1985.
