Australia's official currency is the Australian dollar. Paper currency comes in denominations of $5, $10, $20, $50 and $100. Coins are minted in denominations of 5, 10, 20 and 50 cents, $1 and $2.
Australian currency is notated with a dollar sign ($) within Australia. Internationally, it is notated as "A$" or "AUD" to distinguish it from other currencies. Colloquially, the currency is known as the "Aussie dollar."
Each denomination of Australian banknotes is printed on a different color field and features a significant figure from Australian history, including Australia’s first female parliamentarian Edith Cowan, Aboriginal writer and inventor David Unaipon and the Royal Flying Doctor Service, known as the world's first aerial medical service. Coins celebrate the continent's unique fauna and flora. For example, the $1 coin depicts five kangaroos, while the 20 cent coin depicts a platypus.
