The Australian dollar was introduced as a [[decimal currency]] on 14 February 1966 to replace the non-decimal [[Australian pound]], with the conversion rate of two dollars to the pound (£A1 = A$2). It is subdivided into 100 [[cent (currency)|cents]]. The $ symbol precedes the amount. On the introduction of the currency, the $ symbol was intended to have two strokes, but the version with one stroke has also always been acceptable.<ref>{{Cite book |title=Style Manual: For Authors and Printers of Australian Government Publications |publisher=Commonwealth Government Printing Office |year=1966 |edition=1st |location=Canberra |page=35 |language=en |oclc=10365249}}</ref><ref>{{cite book |last=Australian Decimal Currency Board |title=The decimal currency handbook : a comprehensive guide to Australia's new decimal currency and the changeover period - planned to begin in 1966 |date=1965 |page=19 |id=[[National Library of Australia|NLA]]: [https://catalogue.nla.gov.au/catalog/585292 585292]}}</ref>

{{Main|History of Australian currency}}

=== Background ===
Before [[Australian federation|Federation]] in 1901, the six colonies that comprised Australia had separate currencies, all of which closely replicated the [[pound sterling|British currency system]], and were usually exchangeable with each other on a one-to-one basis. Hence Federation was not seen as urgently requiring a single, unified currency. For another 10 years, colonial banknotes and coins continued to be the main circulating currencies.

In 1902, a select committee of the [[Australian House of Representatives|House of Representatives]], chaired by [[George Edwards (Australian politician)|George Edwards]], had recommended that Australia adopt a single, national decimal currency, with a pound divided into ten [[Florin (British coin)|florin]]s and each florin comprising 100 cents.<ref>{{cite news |url = https://www.aph.gov.au/Parliamentary_Business/Committees/House_of_Representatives_Committees?url=reports%2F1902%2F1902_ppd4.pdf |title = Report from the Select Committee on Coinage |publisher = Commonwealth of Australia |date = 3 April 1902 |access-date = 31 October 2019 |archive-date = 19 December 2019 |archive-url = https://web.archive.org/web/20191219173736/https://www.aph.gov.au/Parliamentary_Business/Committees/House_of_Representatives_Committees?url=reports%2F1902%2F1902_ppd4.pdf |url-status = live }}</ref> However, the recommendation was not acted upon.

The [[Australian pound]] (£A) was introduced in 1910, at par with the [[pound sterling]]{{snd}} £A1 = £1 (UK). Like the UK pound, it was divided into 240 pence, or 20 shillings (each comprising 12 pence). In December 1931, the Australian currency was devalued by 25%, so that one pound five shillings Australian was equivalent to one pound sterling.<ref>{{Cite web |url=https://treasury.gov.au/sites/default/files/2019-03/03_Colin_Clark_speech.pdf |title=What have we learnt?

In 1937, a banking [[Royal commissions in Australia|royal commission]], appointed by the [[Lyons government]], recommended that Australia adopt "a system of decimal coinage ... based upon the division of the Australian pound into [[Mill (currency)|1000 parts]]".<ref name="new">{{cite news |url = https://museum.rba.gov.au/exhibitions/the-decimal-revolution/a-new-currency/ |title = A New Currency |publisher = Reserve Bank of Australia Museum |access-date = 17 October 2019 |archive-date = 29 November 2019 |archive-url = https://web.archive.org/web/20191129032752/https://museum.rba.gov.au/exhibitions/the-decimal-revolution/a-new-currency/ |url-status = live }}</ref><ref>{{Cite report |url=https://parlinfo.aph.gov.au/parlInfo/download/publications/tabledpapers/HPP052016003213/upload_pdf/HPP052016003213_1937_74.pdf;fileType=application%2Fpdf#search=%22publications/tabledpapers/HPP052016003213%22 |title=Royal Commission appointed to inquire into the monetary and banking systems at present in operation in Australia |date=24 August 1937}}</ref> This recommendation was not accepted either.

=== Adoption of the dollar ===
[[File:Dollar Bill - The Decimal Currency Jingle.webm|thumb|1966 government advertisement jingle on the change to decimal currency]]
In February 1959, treasurer [[Harold Holt]] appointed a Decimal Currency Committee, chaired by [[Walter D. Scott]], to examine the merits of decimalisation. The committee reported in August 1960 in favour of decimalisation and proposed that a new currency be introduced (from February 1963), to be modelled on South Africa's replacement of the [[South African pound]] with the [[South African rand|rand]] (worth 10 shillings or {{frac|2}} pound). The [[Menzies Government (1949–66)|Menzies government]] announced its support for decimalisation in July 1961, but delayed the process in order to give further consideration to the implementation process.<ref>{{cite news |url=https://www.abs.gov.au/ausstats/abs@.nsf/featurearticlesbytitle/9A953DE15F376525CA256F2A00073477?OpenDocument |title=Report of the 1959 Decimal Currency Committee |publisher=Australian Bureau of Statistics |year=1959 |access-date=17 October 2019 |archive-date=22 December 2019 |archive-url=https://web.archive.org/web/20191222144523/https://www.abs.gov.au/ausstats/abs@.nsf/featurearticlesbytitle/9A953DE15F376525CA256F2A00073477?OpenDocument |url-status=live }}</ref> In April 1963, Holt announced that a decimal currency was scheduled to be introduced in February 1966, with a base unit equal to 10 shillings, and that a Decimal Currency Board would be established to oversee the transition process.<ref name="new" />

A public consultation process was held in which over 1,000 names were suggested for the new currency. This was reduced to a shortlist of seven names: austral, crown, dollar, pound, regal, tasman and royal.<ref>{{Cite book |last1=Curran |first1=James |title=The unknown nation: Australia after empire |last2=Ward |first2=Stuart |date=2010 |publisher=Melbourne University Publishing |isbn=978-0-522-85645-3 |location=Carlton, Vic |page=94}}</ref> In June 1963, Holt announced that the new currency would be called the "royal". This met with widespread public disapproval, and three months later it was announced that it would instead be named the "dollar".<ref>{{cite news |url = https://www.moadoph.gov.au/blog/the-introduction-of-decimal-currency-how-we-avoided-nostrils-and-learned-to-love-the-bill/ |title = The Introduction of Decimal Currency: How We Avoided Nostrils and Learned to Love the Bill |publisher = Museum of Australian Democracy |access-date = 17 October 2019 |archive-date = 20 December 2019 |archive-url = https://web.archive.org/web/20191220113518/https://www.moadoph.gov.au/blog/the-introduction-of-decimal-currency-how-we-avoided-nostrils-and-learned-to-love-the-bill/ |url-status = live }}</ref>

The pound was replaced by the dollar on 14 February 1966<ref>{{cite web |title=Introducing the New Decimal Banknotes |url=http://museum.rba.gov.au/displays/rba-currency-reform/#introducing-the-new-decimal-banknotes |website=Reserve Bank of Australia Museum |publisher=[[Reserve Bank of Australia]] |access-date=31 December 2015 |archive-url=https://web.archive.org/web/20160427094349/http://museum.rba.gov.au/displays/rba-currency-reform/#introducing-the-new-decimal-banknotes |archive-date=27 April 2016 |url-status=dead }}</ref> with the conversion rate of A$2 = £A1. For example, a pre-decimal amount of nine pounds, sixteen shillings and sixpence (£A9 16s 6d) became $19.65 in terms of dollars and cents. Since Australia was still part of the fixed-exchange [[sterling area]], the exchange rate was fixed to the [[pound sterling]] at a rate of A$1 = 8s sterling (or £1 (UK) = A$2.50, and in turn £1 (UK) = {{USD|link=yes}} 2.80). In 1967, Australia effectively left the sterling area when the pound sterling was devalued against the US dollar from US$2.80 to US$2.40, but the Australian dollar chose to retain its peg to the US dollar at A$1 = US$1.12 (hence appreciating in value versus sterling).

The Australian dollar is legal tender in its external territories: [[Christmas Island]], [[Cocos (Keeling) Islands]], and [[Norfolk Island]]; and is also official currency in [[Kiribati]], [[Nauru]], and [[Tuvalu]]. It was legal tender in [[Papua New Guinea]] until 31 December 1975 when it was replaced by the [[Papua New Guinean kina|kina]], and in [[Solomon Islands]] until 1977 when it was replaced by the [[Solomon Islands dollar]].

== Coins ==
{{Main|Coins of the Australian dollar}}

In 1966, coins were introduced in denominations of 1 and 2 cents (bronze); 5, 10, and 20 cents ([[cupronickel]]; 75% copper, 25% nickel); and 50 cents (silver, then cupronickel). The 50-cent coins in 80% silver were no longer minted after March 1968 due to the intrinsic value of the silver content rising to exceed the face value of the coins.<ref>{{Cite web |title=Fifty Cents |url=https://www.ramint.gov.au/fifty-cents |access-date=2024-05-14 |website=[[Royal Australian Mint]] |date=8 January 2016 |publisher=[[Australian Government]] |language=en-AU}}</ref> [[Aluminium bronze]] (92% copper, 6% aluminium, 2% nickel) 1 dollar coins were introduced in 1984, followed by aluminium bronze 2 dollar coins in 1988, to replace the banknotes of that value. In everyday Australian parlance, these coins collectively are referred to as "gold coins". 1 and 2 cent coins were discontinued in 1991 and withdrawn from circulation in 1992; since then cash transactions have been [[Swedish rounding|rounded to the nearest 5 cents]].

Australia's coins are produced by the [[Royal Australian Mint]], which is located in the nation's capital, [[Canberra]]. Since opening in 1965, the Mint has produced more than 14 billion circulating coins, and has the capacity to produce more than two million coins per day, or more than 600 million coins per year.

Current Australian 5, 10 and 20 cent coins are identical in size to the former Australian, New Zealand, and British sixpence, shilling, and two shilling (florin) coins. Pre-decimal Australian coins remain legal tender for 10 cents per shilling. Before 2006 the old New Zealand 5, 10 and 20 cent coins were often mistaken for Australian coins of the same value, and vice versa, and therefore circulated in both countries. The UK replaced these coins with smaller versions from 1990 to 1993, as did New Zealand in 2006. Still, some confusion occurs with the larger-denomination coins in the two countries; Australia's $1 coin is similar in size to New Zealand's $2 coin, and the New Zealand $1 coin is similar in size to Australia's $2 coin.

With a mass of {{Convert|15.55|g|oz}} and a diameter of {{Convert|31.51|mm|in|frac=32}}, the Australian 50-cent coin is one of the largest coins used in the world today.

=== Commemorative coins ===
{{See also|Australian commemorative coins}}

The [[Royal Australian Mint]] also has an international reputation for producing quality numismatic coins. It has first issued commemorative 50-cent coins in 1970, commemorating [[James Cook]]'s exploration along the east coast of the Australian continent, followed in 1977 by a coin for Queen Elizabeth II's [[Silver Jubilee of Elizabeth II|Silver Jubilee]], the wedding of [[Charles, Prince of Wales]] and [[Diana, Princess of Wales|Lady Diana Spencer]] in 1981, the [[Brisbane]] [[Commonwealth Games]] in 1982, and the [[Australian Bicentenary]] in 1988. Issues expanded into greater numbers in the 1990s and the 21st century, responding to collector demand. Commemorative designs have also been featured on the circulating two dollar, one dollar, and 20 cent coins.

In commemoration of the 40th anniversary of [[decimal currency]], the 2006 mint [[Proof coinage|proof]] and [[Coin grading|uncirculated]] sets included one- and two-cent coins. In early 2013, Australia's first triangular coin was introduced to mark the 25th anniversary of the opening of Parliament House. The silver $5 coin is 99.9% silver, and depicts Parliament House as viewed from one of its courtyards.<ref>{{Cite news |url=https://www.abc.net.au/news/2013-05-09/first-triangular-coin-celebrates-parliament-birthday/4679654 |title=Triangular coin celebrates Parliament House's birthday |work=[[ABC News (Australia)|ABC News]] |date=8 May 2013 |access-date=25 September 2022 |archive-url=https://web.archive.org/web/20130511002654/https://www.abc.net.au/news/2013-05-09/first-triangular-coin-celebrates-parliament-birthday/4679654 |archive-date=11 May 2013 |url-status=live}}</ref>

The first paper issues of the Australian dollar were issued in 1966. The $1, $2, $10 and $20 notes had exact equivalents in the former pound notes. The $5 note was issued in 1967, the $50 was issued in 1973 and the $100 was issued in 1984.<ref>''History of Banknotes'' http://banknotes.rba.gov.au/australias-banknotes/history/ {{Webarchive|url=https://web.archive.org/web/20151025162900/http://banknotes.rba.gov.au/australias-banknotes/history/ |date=25 October 2015 }}</ref>

The $1 banknote was replaced by [[Australian one dollar coin|a $1 coin]] in 1984, while the [[$2 note (Australian)|$2 banknote]] was replaced by [[Australian two dollar coin|a smaller $2 coin]] in 1988.<ref name="rbafgfysjf-mus-inflate-note">{{Cite web |url=http://museum.rba.gov.au/displays/rba-currency-reform/#inflation-and-the-note-issue |title=The Reserve Bank and Reform of the Currency: 1960–1988, Inflation and the Note Issue |publisher=Reserve Bank of Australia |work=Reserve Bank of Australia Music um |access-date=31 December 2015 |archive-url=https://web.archive.org/web/20160427094349/http://museum.rba.gov.au/displays/rba-currency-reform/#inflation-and-the-note-issue |archive-date=27 April 2016 |url-status=dead}}</ref> Although no longer printed, all previous notes of the Australian dollar remain legal tender.<ref name="rba-legal">{{cite web|url=http://banknotes.rba.gov.au/legal/deliberate-damage/|title=DELIBERATE DAMAGE|publisher=[[Reserve Bank of Australia]]|quote=All Australian banknotes, present and all past issues, are lawfully current in Australia.|work=Legal|access-date=9 February 2015|archive-date=4 March 2015|archive-url=https://web.archive.org/web/20150304102856/http://banknotes.rba.gov.au/legal/deliberate-damage/|url-status=live}}</ref>

=== First polymer series ===
Australia was the first country to produce [[polymer banknote]]s,<ref>{{Cite news |url=https://www.bbc.co.uk/news/magazine-20071644 |work=[[BBC News]] |title=Wi-fi, dual-flush loos and eight more Australian inventions |date=8 November 2012 |access-date=25 September 2022 |archive-url=https://web.archive.org/web/20121108070446/https://www.bbc.co.uk/news/magazine-20071644 |archive-date=8 November 2012 |url-status=live}}</ref> more specifically made of [[polypropylene]] polymer, which were produced by [[Note Printing Australia]]. These polymer notes are cleaner than paper notes, are more durable and easily recyclable.

The first polymer banknote was issued in 1988 as a $10 note<ref>{{Cite web|url=https://www.banknotes.rba.gov.au/australias-banknotes/other-banknotes/index.html|title=Other Banknotes|website=Reserve Bank of Australia Banknotes|access-date=10 October 2021|archive-date=31 March 2022|archive-url=https://web.archive.org/web/20220331123357/https://www.banknotes.rba.gov.au/australias-banknotes/other-banknotes/index.html|url-status=live}}</ref> commemorating the bicentenary of European settlement in Australia. The note depicted on one side a young male Aboriginal person in body paint, with other elements of Aboriginal culture. On the reverse side was the ship ''Supply'' from the First Fleet, with a background of Sydney Cove, as well as a group of people to illustrate the diverse backgrounds from which Australia has evolved over 200 years.

The first polymer series was rolled out starting 1992 and featured the following persons:

* The $100 note features world-renowned soprano [[Nellie Melba|Dame Nellie Melba]] (1861–1931), and the distinguished soldier, engineer and administrator [[John Monash|General Sir John Monash]] (1865–1931).<ref>{{Cite web |url=https://www.banknotes.rba.gov.au/australias-banknotes/banknotes-in-circulation/hundred-dollar/index.html |title=$100 Banknote |publisher=Reserve Bank of Australia Banknotes |access-date=10 October 2021 |archive-date=10 October 2021 |archive-url=https://web.archive.org/web/20211010090612/https://www.banknotes.rba.gov.au/australias-banknotes/banknotes-in-circulation/hundred-dollar/index.html |url-status=live}}</ref>

A special centenary issue of the $5 note in 2001 featured [[Henry Parkes|Sir Henry Parkes]] and [[Catherine Helen Spence]].

Australia also prints polymer banknotes for a number of other countries through [[Note Printing Australia]], a wholly owned subsidiary of the Reserve Bank of Australia. Note Printing Australia prints polymer notes or simply supplies the polymer substrate<ref>{{Cite web |url=http://www.bankofcanada.ca/wp-content/uploads/2011/06/spencer.pdf |page=4 |title=Paying with Polymer: Developing Canada's New Bank Notes |publisher=[[Bank of Canada]] |date=20 June 2011 |access-date=12 August 2015 |archive-url=https://web.archive.org/web/20110626150611/https://www.bankofcanada.ca/wp-content/uploads/2011/06/spencer.pdf |archive-date=26 June 2011 |url-status=live}}</ref> for a growing number of other countries including [[Bangladesh]], [[Brunei]], [[Chile]], [[Kuwait]], [[Malaysia]], [[Mexico]], [[Nepal]], [[New Zealand]], [[Papua New Guinea]], [[Romania]], [[Samoa]], [[Singapore]], [[Solomon Islands]], [[Sri Lanka]] and [[Vietnam]]. Many other countries are showing a strong interest in the new technology.

=== Second polymer series ===
On 27 September 2012, the [[Reserve Bank of Australia]] stated that it had ordered work on a project to upgrade the current banknotes. The upgraded banknotes would incorporate a number of new future proof security features<ref>Media Release: R.B.A.: ''Upgrading Australia's Banknotes'' http://www.rba.gov.au/media-releases/2012/mr-12-27.html {{Webarchive|url=https://web.archive.org/web/20130403141719/http://www.rba.gov.au/media-releases/2012/mr-12-27.html |date=3 April 2013 }}</ref> and include tactile features like Braille dots for ease of use of the visually impaired.<ref>"Next Generation Banknotes: Additional Feature for the Vision Impaired". www.rba.gov.au (Press release).

== Exchange rates ==
=== Exchange rate history ===
[[File:Euro exchange rate to AUD.svg|thumb|right|The cost of one Euro in Australian Dollar]]
<!-- Editor, please don't change this page every time you hear about a new high. Keep in mind style, and edit guides before you do anything. -->

Prior to 1983, Australia maintained a [[fixed exchange rate]]. The Australian pound was initially at par from 1910 with the British pound or £A1 = £1 (UK); from 1931 it was devalued to £A1 = 16s sterling. This reflected its historical ties as well as a view about the stability in value of the British pound.

From 1946 to 1971, Australia maintained a peg under the [[Bretton Woods system]], a fixed exchange rate system that pegged the [[U.S. dollar]] to gold, but the Australian dollar was effectively pegged to sterling until 1967 at £1 sterling = £A1 5s = A$2.50 = US$2.80. In 1967 Australia did not follow the pound sterling devaluation and remained fixed to the U.S. dollar at A$1 = US$1.12.

With the breakdown of the Bretton Woods system in 1971, Australia converted the traditional peg to a fluctuating rate against the US dollar. In September 1974, Australia valued the dollar against a basket of currencies called the [[trade weighted index]] (TWI) in an effort to reduce the fluctuations associated with its tie to the US dollar.<ref>{{cite web |url=http://www.abs.gov.au/ausstats/abs@.nsf/90a12181d877a6a6ca2568b5007b861c/d4a22ad91e0348bfca256fd3007baf93!OpenDocument |title=1350.0 – Australian Economic Indicators, Mar 1998 |publisher=[[Australian Bureau of Statistics]] |date=8 December 2006 |access-date=19 April 2011 |archive-date=16 October 2015 |archive-url=https://web.archive.org/web/20151016030017/http://www.abs.gov.au/ausstats/abs@.nsf/90a12181d877a6a6ca2568b5007b861c/d4a22ad91e0348bfca256fd3007baf93!OpenDocument |url-status=live }}</ref> The daily TWI valuation was changed in November 1976 to a periodically adjusted valuation.

The highest valuation of the Australian dollar relative to the U.S. dollar was during the period of the peg to the U.S. dollar.  On 9 September 1973, the peg was adjusted to US$1.4875, the fluctuation limits being changed to US$1.485–US$1.490;<ref>{{cite book |title = World Currency Yearbook, 1984 |year=1985 |isbn=0-917645-00-6 |page=75 |editor-first = Philip P. |editor-last = Cowitt |publisher =International Currency Analysis }}</ref> on both 7 December 1973 and 10 December 1973, the noon buying rate in New York City for cable transfers payable in foreign currencies reached its highest point of 1.4885 U.S. dollars to one dollar.<ref>{{cite web |title = U.S. / Australia Foreign Exchange Rate |publisher = Federal Reserve Bank of St. Louis |url = http://research.stlouisfed.org/fred2/data/DEXUSAL.txt |access-date = 3 January 2020 |archive-date = 2 January 2016 |archive-url = https://web.archive.org/web/20160102151628/https://research.stlouisfed.org/fred2/data/DEXUSAL.txt |url-status = live }}</ref>

The lowest ever value of the dollar after it was floated was 47.75 US cents in April 2001.<ref>{{cite news |title=Global risk weighs on Howard's agenda |url=http://edition.cnn.com/2001/BUSINESS/asia/11/12/aust.economy.biz/ |access-date=14 October 2010 |publisher=[[CNN]] |date=12 November 2001 |archive-date=15 May 2011 |archive-url=https://web.archive.org/web/20110515140207/http://edition.cnn.com/2001/BUSINESS/asia/11/12/aust.economy.biz/ |url-status=live }}</ref> It returned to above 96 US cents in June 2008,<ref>{{cite news |title=Dollar Falls Before RBA Meeting: New Zealand's Drops |url=https://www.bloomberg.com/apps/news?pid=newsarchive&sid=aQV4HwdZoDek |access-date=14 October 2010 |publisher=[[Bloomberg L.P.|Bloomberg]] |date=30 June 2008 |archive-date=11 May 2011 |archive-url=https://web.archive.org/web/20110511042749/http://www.bloomberg.com/apps/news?pid=newsarchive&sid=aQV4HwdZoDek |url-status=live }}</ref> and reached 98.49 later that year. Although the value of the dollar fell significantly from this high towards the end of 2008, it gradually recovered in 2009 to 94 US cents.

Since the end of China's large-scale purchases of Australian commodities in 2013, however, the Australian dollar's value versus the US dollar has since plunged to $0.88 as of end-2013, and to as low as $0.57 in March 2020. As of 2024, it has traded at a range of $0.63 to $0.68.

=== Determinants of value ===
In 2016, the Australian dollar was the fifth most traded currency in world [[foreign exchange market]]s, accounting for 6.9% of the world's daily share (down from 8.6% in 2013)<ref>{{cite web |url = http://www.businessinsider.com/the-most-traded-currencies-in-2016-2016-12 |title = Here are the most traded currencies in 2016 |website = Business Insider |first = Jeff |last = Desjardins |date = 29 December 2016 |access-date = 30 June 2017 |archive-date = 7 July 2017 |archive-url = https://web.archive.org/web/20170707135916/http://www.businessinsider.com/the-most-traded-currencies-in-2016-2016-12 |url-status = live }}</ref> behind the [[United States dollar]], the [[euro]], the [[Japanese 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 [[Economy of Australia|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.<ref name="SMH1" />

Economists posit that commodity prices are the dominant driver of the Australian dollar, and this means changes in exchange rates of the Australian dollar occur in ways opposite to many other currencies.<ref>{{cite web |url = http://www.westpac.com.au/docs/pdf/aw/economics-research/MarketInsights.pdf |publisher=Westpac |title=Westpac Market Insights March 2011 |page=4 |access-date=8 April 2011 |archive-url = https://web.archive.org/web/20110307030949/https://www.westpac.com.au/docs/pdf/aw/economics-research/MarketInsights.pdf |archive-date=7 March 2011 |url-status=dead}}</ref> For decades, Australia's balance of trade has depended primarily upon commodity exports such as minerals and agricultural products. This means the Australian dollar varies significantly during the business cycle, rallying during global booms as Australia exports raw materials, and falling during recessions as mineral prices slump or when domestic spending overshadows the export earnings outlook. This movement is in the opposite direction to other reserve currencies, which tend to be stronger during market slumps as traders move value from falling stocks into cash.

The Australian dollar is a [[reserve currency]] and one of the most traded currencies in the world.<ref name="SMH1">{{cite news |url=https://www.smh.com.au/business/aussie-now-fifth-mosttraded-currency-20100901-14nma.html |title=Aussie now fifth most traded currency |newspaper=[[The Sydney Morning Herald]] |date=2 September 2010 |access-date=19 April 2011 |last=Yeates |first=Clancy |archive-date=5 April 2011 |archive-url=https://web.archive.org/web/20110405073729/http://www.smh.com.au/business/aussie-now-fifth-mosttraded-currency-20100901-14nma.html |url-status=live }}</ref> Other factors in its popularity include a relative lack of central bank intervention, and general stability of the Australian economy and government.<ref>{{cite web |url=http://www.safehaven.com/article/4608/analyzing-the-australian-dollar-up-down-and-under |title=Analyzing the Dollar – Up, Down, and Under |first=Gary |last=Dorsch |date=14 February 2006 |website=SafeHaven.com |access-date=8 April 2011 |archive-date=31 October 2010 |archive-url=https://web.archive.org/web/20101031201958/http://www.safehaven.com/article/4608/analyzing-the-australian-dollar-up-down-and-under |url-status=live }}</ref> In January 2011 at the [[World Economic Forum]] in [[Davos]], [[Switzerland]], [[Alexey Ulyukaev]] announced that the [[Central Bank of Russia]] would begin keeping Australian dollar reserves.<ref>{{cite news |url=http://en.ria.ru/business/20120126/170960429.html |title=Russia to Keep Dollar Reserves From February |date=26 January 2012 |publisher=[[RIA Novosti]] |access-date=27 January 2012 |location=[[Davos]], [[Switzerland]] |archive-date=12 June 2012 |archive-url=https://web.archive.org/web/20120612135834/http://en.ria.ru/business/20120126/170960429.html |url-status=live }}</ref>

== Legal tender ==
===Within Australia===
Australian notes are [[legal tender]] throughout Australia by virtue of section 36(1) of the ''Reserve Bank Act 1959'' without an amount limit.<ref>{{Cite Legislation AU|Cth|act|rba1959130|Reserve Bank Act 1959|36}}</ref> Section 16 of the ''Currency Act 1965'' similarly provides that Australian coins intended for general circulation are also legal tender, but only for the following amounts:<ref>{{Cite Legislation AU|Cth|act|ca1965120|Currency Act 1965|16}}</ref>
* 1c and 2c coins (withdrawn from circulation from February 1992, but still legal tender): for payments not exceeding 20c
* 5c, 10c, 20c and 50c (of any combination): for payments not exceeding $5
* $1 coins: for payments not exceeding $10
* $2 coins: for payments not exceeding $20
* Non-circulating $10 coins: for payments not exceeding $100<ref name="currency_act">{{Cite web|url=https://www.legislation.gov.au/Details/C2016C01090|title=Currency Act 1965|date=21 October 2016 |access-date=24 July 2018|archive-date=9 May 2019|archive-url=https://web.archive.org/web/20190509005541/https://www.legislation.gov.au/Details/C2016C01090|url-status=live}}</ref>
* Coins of other denominations: no lower limit

However, being legal tender does not necessarily oblige businesses to accept cash. The Reserve Bank states that businesses can set commercial terms for a transaction that requires the use of a non-cash payment.<ref name="rbalegaltender">{{cite web |title=RBA Banknotes: Legal Tender |url=http://banknotes.rba.gov.au/legal/legal-tender/ |url-status=live |archive-url=https://web.archive.org/web/20141213015111/http://banknotes.rba.gov.au/legal/legal-tender/ |archive-date=13 December 2014 |website=rba.gov.au}}</ref> However, a business may technically be required to accept cash if they are taken to court, but this is usually not a viable option for consumers.<ref>{{Cite news |last=Watterson |first=Larrisa |date=2024-02-08 |title=Legal tender rights for Australians in the headlines again following Bob Katter's cafe cash snub |url=https://www.abc.net.au/news/2024-02-08/right-to-pay-with-cash-or-card-legal-tender-bob-katter/103441698 |access-date= |work=ABC News (Australia) |language=en-AU}}</ref>

===Outside Australia===
Australian notes and coins are also legal tender in the independent sovereign states of [[Kiribati]], [[Nauru]], and [[Tuvalu]].<ref name=nauru/><ref name=tuvalu/><ref name=kiribati/> Nauru never had its own currency. Tuvalu and Kiribati additionally had their respective [[Tuvaluan dollar|Tuvaluan]] and [[Kiribati dollar|Kiribati]] dollars at par with the Australian dollar. They are legal tender in their respective countries but not in Australia. However, both countries no longer produce coinage since the 1990s and have never produced their own banknotes. As a result, the Australian dollar is the dominant currency in both countries.

Tuvalu also issues non-circulating commemorative bullion coins produced by the [[Perth Mint]].<ref>{{cite web|url=https://www.perthmint.com/news/collector/coin-collecting/explaining-tuvalus-role-in-modern-coins/|title=Explaining Tuvalu's role in modern coins|publisher=Perth Mint|date=27 August 2019|access-date=11 February 2023}}</ref><ref>{{cite web|url=https://www.abc.net.au/news/2020-05-31/tuvalu-pacific-collectable-coins-perth-mint/12290590|title=Why the tiny Pacific nation of Tuvalu wants a bigger share of the collectable coin market|publisher=ABC News|date=31 May 2020|access-date=11 February 2023}}</ref>
