What is the local currency?
The currency in Australia is the Australian Dollar (AUD)
Should I change money before I go?
You may want to exchange money before you travel, but there are money exchange points as well as ATMs at all locations throughout the trip. You will also be able to pay with any major credit cards (not all places will take AMEX).
How much should I budget per day for extras?
Around $90 - $100 AUD a day should be plenty, but this is guidance only as you know your spending patterns better than we do. If you plan on buying gifts and souvenirs, remember to budget extra for these.
Is it customary to tip?
Tipping is not obligatory, but if the service is good in restaurants or bars giving a 10- 12.5% tip is fairly normal in Australia. Then for your guide and driver, it is customary, though not compulsory to tip them around $10 a day, this would normally be given at the end of the adventure and is completely up to you and whether you feel they have earned it.
