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.

Camira Sailing Adventure is an all inclusive tour, so you shouldn't have to reach for your wallet. Meals are included for the Great Barrier Reef Adventure day cruise and Reefsleep, however drinks, snacks and souvenirs are available from the kiosk on board the boat or on the pontoon.  Our Full and Half day Whitehaven Beach cruises will have a meal or snack (depending on which option you choose) included; drinks, snacks and souvenirs are available for sale on board the boat.
