I recently had a 5 day holiday on Dunk Island. The accommodation was satisfactory and the island is beautiful. Unfortunately there seemed to be problem with reservations. Despite emailing my arrival and departure details 3 weeks in advance, there was no record of my arrival at Cairns airport and my transfer was not booked. I also had to leave a day early in order to connect with a return flight.
Staff on the island, while sympathetic, did not seem too concerned. Emails to reservations have also not been returned.
Ensure that transfers to the island have been confirmed.
