Australia has a decimal currency system. Notes are a high quality polymer-based synthetic and come in denominations of $5, $10, $20, $50 and $100.
Coin denominations are 5 cent, 10 cent, 20 cent, 50 cent, as well as $1 and $2.
Prices under 5 cents are rounded up or down to the nearest 5 cent - that is, 3 and 4 cent totals are rounded up to nearest 5 cent, while 1 and 2 cent totals are rounded down to nearest 5 cent denomination.
For example - 12 cents would be rounded down to 10 cents. 14 cents would be rounded up to 15 cents.

Tipping is generally not expected within Australia, however it is acceptable to leave a small amount should you feel you have received exceptional service.
