On Feb 14 1966, the currency was decimalised in Australia.
RBA has released interesting material on the 60th anniversary:
In the late 1950s, under the guidance of the Decimal Currency Committee, the Australian Government began to give practical consideration to replacing the imperial system of pounds, shillings and pence with decimal currency – an innovation that had been contemplated since the beginning of the 20th century.
Decimal currency simplified calculations, increasing financial efficiency. However, it represented a radical change to the customary transactions made daily by the nation. In 1963, the government announced that it would introduce decimal currency in 1966. In accordance with the recommendations of the Decimal Currency Committee, it explained that:
-
- a changeover to decimal currency would be set for February 1966
- the major currency unit (subsequently named the dollar) would be equal to ten shillings
- the minor currency unit (subsequently named the cent) would be one hundredth of the major unit, equal to 1 .2d. in the existing currency system
- no fractions of the minor unit would be introduced
- reasonable compensation would be paid to owners of monetary machines that would require conversion.
The Decimal Currency Board was established to oversee the far-reaching program of work. A new series of coins and banknotes was designed as part of the introduction of decimal currency, with imagery that enhanced a sense of the country’s distinctive identity.
