The Australian dollar (sign: $; code: AUD) is the currency of Australia, including its external territories: Christmas Island, Cocos (Keeling) Islands, and Norfolk Island. It is officially used as currency by three independent Pacific Island states: Kiribati, Nauru, and Tuvalu. It is legal tender in Australia. Within Australia, it is almost always abbreviated with the dollar sign ($), with A$ or AU$ sometimes used to distinguish it from other dollar-denominated currencies. The $ symbol precedes the amount. It is subdivided into 100 cents.
The Australian dollar was introduced on 14 February 1966 to replace the pre-decimal Australian pound, with the conversion rate of A$2 per = A£1.
