The Australian dollar is the official currency and legal tender of Australia, including all of its external territories, and three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu. In April 2022, it was the sixth most-traded currency in the foreign exchange market and as of Q4 2023 the seventh most-held reserve currency in global reserves.
The lira was the currency of Italy between 1861 and 2002. It was introduced by the Napoleonic Kingdom of Italy in 1807 at par with the French franc, and was subsequently adopted by the different states that would eventually form the Kingdom of Italy in 1861. It was subdivided into 100 centesimi, which means "hundredths" or "cents". The lira was also the currency of the Albanian Kingdom from 1941 to 1943.
The pound was the currency of Australia from 1910 until 14 February 1966, when it was replaced by the Australian dollar. Like other £sd currencies, it was subdivided into 20 shillings, each of 12 pence.
Australian coins refers to the coins which are or were in use as Australian currency. During the early days of the colonies that formed Australia, foreign as well as British currency was used, but in 1910, a decade after federation, Australian coins were introduced. Australia used pounds, shillings and pence until 1966, when it adopted the decimal system with the Australian dollar divided into 100 cents. With the exception of the first Proclamation Coinage and the holey dollars, all Australian coins remain legal tender despite being withdrawn from circulation.
The Tuvaluan dollar is one of the currencies of Tuvalu, whose unofficial international currency code is TVD. Tuvalu has never had banknotes of its own, and has been issuing coins since 1976. However, the Tuvaluan dollar is used as a unit of account, and is pegged to the Australian dollar at parity. From 1966 to 1976, Tuvalu officially used the Australian dollar. In 1976, Tuvalu began issuing its own coins, which continue to circulate alongside Australian coins. Tuvalu continues to use Australian banknotes. Tuvaluan coins are not legal tender in Australia. Similar to the Faroese króna's relationship to the Danish krone and the Panamanian balboa's relationship to the United States dollar, the Tuvaluan dollar is not an independent currency, but a variation of the Australian dollar.
The Cook Islands dollar was the former currency of the Cook Islands, which now uses the New Zealand dollar, although some physical cash issued for the Cook Islands dollar remains in use. The dollar was subdivided into 100 cents, with some older 50-cent coins carrying the denomination as "50 tene".
The twelve-sided Australian fifty-cent coin is the third-highest denomination coin of the Australian dollar and the largest in terms of size in circulation. It is equal in size and shape to the Cook Island $5 coin, and both remain the only 12-sided coins in the southern hemisphere. It was introduced in 1969 to replace the round fifty-cent coin issued in 1966.
The twenty-cent coin of the Australian decimal currency system was issued with conversion to decimal currency on 14 February 1966, replacing the florin which was worth two shillings, a tenth of a pound.
The Australian five-cent coin is the lowest-denomination circulating coin of the decimal Australian dollar introduced in 14 February 1966, replacing the pre-decimal sixpence. It has been the lowest-denomination coin in general circulation since the withdrawal of the one-cent and two-cent coins in 1992.
The Australian ten-cent coin is a coin of the decimal Australian dollar. When the dollar was introduced as half of an Australian pound on 14 February 1966, the coin inherited the specifications of the pre-decimal shilling; both coins were worth one twentieth of a pound and were called "bob". On introduction it was the fourth-lowest denomination coin. Since the withdrawal from circulation of the one and two cent coins in 1992, it has been the second-lowest denomination coin in circulation.
The Australian one-dollar coin is the second most valuable circulation denomination coin of the Australian dollar after the two-dollar coin; there are also non-circulating legal-tender coins of higher denominations.
The Australian two-dollar coin is the highest-denomination coin of the Australian dollar. It was first issued on 20 June 1988, having been in planning since the mid-1970s. It replaced the Australian two-dollar note due to having a longer circulatory life. The only "mint set only" year was 1991.
The Australian one-hundred-dollar note was first issued in 1984 as a paper note. There have been two different issues of this denomination: initially a very light turquoise-blue paper note, and from May 1996, a green polymer note. Since the start of issue there have been six signature combinations. Two other combinations were not issued.
The cent, formally the one-cent coin, was the lowest-denomination coin of the Australian dollar. It was introduced on 14 February 1966 in the decimalisation of Australian currency and was withdrawn from circulation in 1992. It is still minted as a non-circulating coin. A one-cent coin in 1966 would have a purchasing power equal to about 16c in 2023 values.
The round fifty cent coin was the highest-denomination and largest diameter coin of the Australian decimal coins, introduced in 1966. It has a nominal value of half an Australian dollar, equivalent to five shillings in the pre-decimal accounting system. Due to the large number minted in 1966, and the rising cost of silver, it was not made in any other year. It was replaced by a twelve-sided 50 cent coin in 1969, which retained its reverse of the Australian Coat of Arms.
Pre-decimal Australian coins arose when the Federation of Australia gave the constitutional power to Commonwealth of Australia to mint its own coinage in 1901. The new power allowed the Commonwealth to issue legal tender rather than individually through the six former British self-governing colonies of Queensland, New South Wales, Victoria, Tasmania, South Australia, and Western Australia.
The coins of the Australian dollar were introduced on 14 February 1966, although they did not at that time include the one-dollar or two-dollar coins. The dollar was equivalent in value to 10 shillings in the former currency.
The Australian sixpence circulated from 1910 up until the decimalisation of Australian Currency in 1966. The coins were initially minted in England; however, Australia began to mint their own from the year of 1916 at branches of the Royal Mint in Sydney and Melbourne. The coins which made up Australia's pre-decimal currency were identical to British currency in the characteristics of weight and size. The Coinage Act of 1909–1947, authorised the issue of Australian coins in the select denominations, including the sixpence. By 1916 all silver denominations, including the sixpence, could be minted at the Royal Mint branch in Melbourne. Unique Australian currency was created with decimalisation in 1966.
The Australian pre-decimal halfpenny coin, commonly known as a ha’penny, was the smallest denomination of the Australian Pound in circulation. It was a unit of currency that equalled half of a penny, 1/24 of a shilling, or 1/480 of a pound. The coin was made to be equivalent to the British halfpenny; its dimensions, composition and values were equivalent, and additionally, the two currencies were fixed at par.
Prior to European colonization, early Aboriginal Australian communities traded using items such as tools, food, ochres, shells, raw materials and stories, although there is no evidence of the use of currencies.
