The Australian currency is a decimal currency - there are 100 cents to one dollar.
Five, 10, 20 and 50 cent silver coins are available, and one and two dollar gold coins. Silver and gold is the colour of the coins, not the material. They are made from cupro-nickel (silver) and aluminium-bronze (gold), respectively. Depicted on coins of Australian currency you can find several popular Australian animals: kangaroos (one dollar), the platypus (20 cents), the lyrebird (10 cents) and the echidna or spiny ant-eater (5 cents).
The bank notes are colourful and made from some sort of plastic (a polymer). The denominations of the Australian currency bank notes are five (purple), 10 (blue), 20 (red), 50 (khaki) and 100 (green) dollars. ATMs usually dispense 20 and 50 dollar notes.All notes of the Australian currency show pictures of personalities important to Australia's history.
