The Australian one-cent coin is the smallest denomination coin of the Australian dollar. Coins issued in 1966 circulated for 26 years before, together with coins of the two cent denomination, they were withdrawn from circulation in February 1992. They were not demonetised though and remain legal tender.

Although there was no formal mint mark, the products of the Melbourne, Perth and Canberra mints can be identified by comparison of the whiskers on the animal's left. The Melbourne coins have the first whisker (nearest the rim) blunted; Perth coins have the second whisker blunted while Canberra pieces show no blunting.

There were also 18,110 proof sets made.
