The Australian dollar 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.
Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt.
The pound was the currency of Australia from 1910 until 14 February 1966, when it was replaced by the Australian dollar. As with 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of the first Proclamation Coinage and the holey dollars, all Australian coins remain legal tender despite being withdrawn from circulation.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 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 Australian twenty-cent coin (Quinter) 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 (Nickel) 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 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 twenty-dollar note was issued when the currency was changed from the Australian pound to the Australian dollar on 14 February 1966. It replaced the £10 note which had similar orange colouration. There have been only three different issues of this denomination: a paper note which had a gradient of yellow and red, with a distinct orange background, and two designs of polymer note which can be recognised for their distinct red-orange colouration. The first polymer note was issued on 31 October 1994 and the Next Generation polymer banknote was issued on 9 October 2019.
The Australian ten-dollar note was issued when the currency was changed from the Australian pound to the Australian dollar on 14 February 1966; it replaced the £5 note, which included the same blue colouration. There have been four different issues of this denomination: a paper banknote; a commemorative hi-polymer note, to celebrate the bicentennial of Australian settlement ; the 1993–2017 polymer note; and from September 2017 a polymer note featuring a transparent window.
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.
The Australian two-cent coin was introduced in 1966 and was the coin of the second-lowest denomination until it was withdrawn from circulation in 1992. It is still counted as legal tender, but is subject to some restrictions, and one-cent and two-cent coins are legal tender only up to the sum of 20 cents.
The Australian five-dollar note was first issued on 29 May 1967, fifteen months after the currency was changed from the pound to the dollar on 14 February 1966. It was a new denomination with mauve colouration – the pre-decimal system had no denomination with a value of £21⁄2. The first polymer version of the note was introduced in 1992. A major design update was issued from 1 September 2016, with a minor update to the signatures in 2019.
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, the equivalent of five shillings in pre-decimal currency. 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.
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 notes of the Australian dollar were first issued by the Reserve Bank of Australia on 14 February 1966, when Australia changed to decimal currency and replaced the pound with the dollar. This currency was a lot easier for calculating compared to the previous Australian pound worth 20 shillings or 240 pence.
The coins of the New Zealand dollar are used for the smallest physical currency available in New Zealand. The current denominations are ten cents, twenty cents, fifty cents, one dollar and two dollars. The $1 and $2 coins are minted in a gold colour, the 20c and 50c coins are silver colour and the 10c coin is plated in copper.
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 history of Australian currency commences with the first European settlement of Australia on 26 January 1788. At the time, New South Wales was a British colony, and the English currency was in formal circulation, though the supply was insufficient and alternative forms of exchange were resorted to. A national Australian currency was created in 1910, as the Australian Pound, which in 1966 was decimalized as the Australian Dollar.
