Prior to 1910, Australia used the British currency. British coins continued to circulate with Australian Coins for many years.
The Australian coinage was first introduced in 1910 and included the Threepence, Sixpence, Shilling and Florin. All coins were based on the equivalent British Coins and were made from sterling silver.
The following year in 1911, the One Penny and Halfpenny coins were introduced, again all based on the equivalent British coins and were made from bronze.
Paper money was introduced in 1913.
In the early 1960's, it was decided that Australia should have a decimal currency rather than the cumbersome British Imperial style of currency. It was eventually decided that Australia would adopt the Dollar of 100 cents as its currency.
The last of the predecimal coins were minted in 1964. On the 14th of February, 1966 the new Australian decimal currency was issued to a well prepared Australian public.
