Production:
The initial 1966 issue was produced by three mints: 146.5 million coins at the Royal Australian Mint in Canberra, 239 million at the Melbourne Mint, and 26.6 million at the Perth Mint. Except for the years 1966 and 1981, all other one-cent coins were produced at the Canberra mint. In 1981, 40.3 million coins were minted at the British Royal Mint in Llantrisant, Wales, and 183.6 million in Canberra. The coin was not minted in 1986 and was last produced in 1990.
The decision to withdraw the one-cent and two-cent coins was announced by the Treasurer in a Budget Speech on 21 August 1990. The coins were removed due to inflation reducing their value and the high cost of bronze. Around the same time, other countries also eliminated their bronze coins—New Zealand removed its one and two-cent coins in 1990, while the United Kingdom and Ireland transitioned their bronze one and two pence coins to copper-plated steel.

Mint Marks:
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 feathertail glider 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.
