What is the Fijian currency and do I need cash for the islands?

The currency is the Fijian dollar.

There are no banks in the Yasawa Islands so you'll need to plan ahead! The bank at Nadi International Airport is open 24 hours and cash machines are available at Nadi Airport, in Nadi town, Wailoaloa Beach and at Port Denarau.

A number of resorts in the Yasawa Islands do no accept cash so a credit/debit card is a must but it is still advisable to have some cash with you.
