Currency

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

Climate

Adelaide has a hot Mediterranean climate. Mild winters with moderate rainfall and hot, dry summers.

In summer (December to February) the average maximum is around 29 °C (84 °F), but there is considerable variation and Adelaide can usually expect around 3 days a year when the daytime temperature is 40 °C (104 °F) or above.

In winter (June to August) the average maximum is around 15–16 °C (59–61 °F) and the average minimum around 7–8 °C (45–46 °F). Frosts are common in the valleys of the Adelaide Hills, but rare elsewhere. There is usually no appreciable snowfall in Adelaide, except on rare occasions at Mount Lofty and in some towns in the Adelaide Hills.

Adelaide is the driest of the Australian capital cities. Rainfall is unreliable, light and infrequent throughout summer. The average in January and February is around 20 millimetres (0.8 inches), but completely rainless months are by no means uncommon. In contrast, the winter has fairly reliable rainfall with June being the wettest month of the year, averaging around 80 mm.
