Whats the earliest flight I should book, to leave Cairns?
Scuba diving safety experts suggest a minimum of 24 hours between your last dive, and any high-altitude flights. So if you want to do all the dives on our last diving day (the next-to-the-last day of the trip), including the night dive, the earliest you could fly out of Cairns would be mid-evening. You may prefer to spend a night in Cairns and fly out the next day.
