I've been there. Hamilton Island is an urban resort style island but this employee is not employed to swim in Hamilton Island's pools. He needs to explore all those uninhabited island there...Do not forget it's Australia, up there is hellishly hot , you can't swim in bloody ocean because of all those jelly-fishes and sharks, you can't walk freely because of the snakes and other predators ...so it may end up to be literally " a hell of the job". They are not paying that money for nothing...or enjoyment...All though adventurers may still love it...
