Australian money yes, obviously for Australia. Cook Island take New Zealand dollars. If you are going to Rarotonga, it's stunning! We had NZ dollars as we were going to NZ ports, & don't know if there was an alternative. Maybe someone else could reply. We went to Muri Beach on Rarotonga. American Samoa, Figi & Tahiti, US $s.
Thanks. Yes, we are going to Rarotonga - can't wait.
