{{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parlance, these coins collectively are referred to as "gold coins". 1 and 2 cent coins were discontinued in 1991 and withdrawn from circulation in 1992; since then cash transactions have been [[Swedish rounding|rounded to the nearest 5 cents]].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>
