<Tr> <Th> Pegged by </Th> <Td> Tuvaluan dollar and Kiribati dollar at par </Td> </Tr> <P> The Australian dollar (sign: $; code: AUD) is the currency of the Commonwealth of Australia, including its external territories Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru, Tonga, Tuvalu, and Vanuatu . The Australian dollar was legal tender of Papua New Guinea until 1 January 1976, when the Papua New Guinean kina became the sole legal tender . Within Australia, it is almost always abbreviated with the dollar sign ($), with A $or AU $sometimes used to distinguish it from other dollar - denominated currencies . It is subdivided into 100 cents . </P> <P> In 2016, the Australian dollar was the fifth most traded currency in the world, accounting for 6.9% of the world's daily share (down from 8.6% in 2013). It trades in the world foreign exchange markets behind the US dollar, the euro, the yen and the pound sterling . The Australian dollar is popular with currency traders, because of the comparatively high interest rates in Australia, the relative freedom of the foreign exchange market from government intervention, the general stability of Australia's economy and political system, and the prevailing view that the Australian dollar offers diversification benefits in a portfolio containing the major world currencies, especially because of its greater exposure to Asian economies and the commodities cycle . The currency is commonly referred to by foreign - exchange traders as the "Aussie dollar". </P> <P> With pounds, shillings and pence to be replaced by decimal currency on 14 February 1966, many names for the new currency were suggested . In 1963, Prime Minister, Sir Robert Menzies, a monarchist, wished to name the currency the royal . Other proposed names from a public naming competition included more exotic suggestions such as the austral, the oz, the boomer, the roo, the kanga, the emu, the koala, the digger, the zac, the kwid, the dinkum, and the ming (Menzies' nickname). Menzies' influence resulted in the selection of the royal, and trial designs were prepared and printed by the Reserve Bank of Australia . Australian treasurer and future Prime Minister, Harold Holt, announced the decision in Parliament on 5 June 1963 . The royal would be subdivided into 100 cents, but the existing names shilling, florin and crown would be retained for the 10 - cent, 20 - cent and 50 - cent coins respectively . The name royal for the currency proved very unpopular, with Holt and his wife even receiving death threats . On 24 July Holt told the Cabinet the decision had been a "terrible mistake" and it would need to be revisited . On 18 September Holt advised Parliament that the name was to be the dollar, of 100 cents . </P>
