Here in Australia our currency is Australian Dollars (AUD). We also accept American Express, Bankcard, Diners Club, MasterCard, Visa, JCB and their affiliates. Currency exchange is available at banks, hotels and international airports. Try this handy web tool for International Currency Conversion.
Here we have a goods and services tax on purchases (10%) but you may claim this and the Wine Equalisation Tax when departing our shores. For more information visit the Tourist Refund Scheme.
Tipping is not common in Australia. When eating out, shopping or taking taxis, the prices are inclusive of tax or GST as we call it. Of course, tipping is appreciated for exceptional service.
