What is the Australian currency and do I need cash for the islands and day cruises?

The currency is the Australian dollar.

There are banks and ATM facilities at Airlie Beach and Hamilton Island. There is no bank at Daydream Island, however card payments, cash and travellers cheques are accepted. Daydream Island also has ATMs.

Camira Sailing Adventure and our day cruises to Whitehaven Beach are all inclusive, so you shouldn't have to reach for your wallet. Meals are include for Great Barrier Reef Adventures and Reefsleep, however drinks, snacks and souvenirs are available from the kiosk on board the boat or on the pontoon.
