Australia commemorates the 60th anniversary of its transition to decimal currency, which took place on February 14, 1966. This change marked a pivotal moment in the nation's economic history as it moved away from the complex imperial system of pounds, shillings, and pence to the more straightforward decimal system of dollars and cents. This transition, known as C-Day, was part of a broader global trend, with many countries having already adopted decimal currency by the time Australia made the switch.

The move to decimalisation was supported by an extensive education and publicity campaign that lasted two years leading up to the changeover. The campaign aimed to familiarize the public with the new currency system and included catchy jingles, notable among them the tune sung by a cartoon character named Dollar Bill, which communicated the key details of the transition. This effort was essential in helping the general population understand and embrace the new currency, ensuring a smoother implementation of the decimal system.

The establishment of the Royal Australian Mint in 1965 in Canberra was a crucial step in managing this transition. It emphasized the government's commitment to making the change as effective as possible. As Australia reflects on the past six decades, the decimal currency system is recognized for simplifying daily transactions, aligning with global standards, and contributing to the efficiency of the nation's economy.
