The ISO 4217 currency code for Australian Dollar currency.
ISO 4217 code for the Australian dollar. It was introduced in 1966, replacing the Australian pound. It was initially pegged to the British pound, but changed the peg to the U.S. dollar in 1967. It is now a floating currency and is the sixth-most widely traded currency in the world. It is especially important in the South Pacific region, where a number of small nations either use the dollar or peg their currencies to it at a 1:1 ratio.
