The dollar is the currency of the Commonwealth of Australia, including Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru and Tuvalu. The Australian dollar's ISO 4217 code is AUD but it is often abbreviated with the dollar sign $. A$ or AU$ is often used informally to distinguish it from other dollar-denominated currencies. It is subdivided into 100 cents.
On 14 February 1966 the dollar was introduced at a rate of two dollars per pound, or ten shillings per dollar. At its introduction, it was pegged to sterling at a rate of 1 dollar = 8 shillings (2.5 dollars = 1 pound). In 1967, Australia effectively left the sterling area for the first time. When sterling devalued in 1967 against the U.S. dollar, the Australian dollar did not follow. It maintained its peg to the U.S. dollar at the same rate of 1 Australian dollar = 1.12 U.S. dollars.
