* Australian money is very colorful. A $100 note is green, a $50 note is yellow, $20 note is red, $10 is blue, and a $5 note is purple. Also the size of the note gets bigger as the value increases. instead of having a $1 note, they have a $1 coin, and a $2 coin too. The coin denominations are $2 coin, $1 coin, 50 cent coin, 20 cent coin, 10 cent coin, and a 5 cent coin. from 5 cent to 50 cent they get bigger, but the $2 coin is smaller than the $1 coin. Also they've completely done away with the penny, so they round the prices to the nearest 5 cents. However they don't round the price until it's time to pay, so you'll see prices for $2.47 for example.
