Pre-decimal Currency (Before 1966)

On 14 February 1966, Australia transitioned to a decimal currency system, introducing the Australian dollar (AUD) and replacing pounds, shillings, and pence. The decimal coins introduced included the 1 cent, 2 cent, 5 cent, 10 cent, 20 cent, and 50 cent coins.

Evolution of Coinage

From 1966 onwards, the coins saw gradual design changes, special commemorative issues, and innovations in minting technology. Queen Elizabeth II has appeared on most coins since decimalization.
