Normally, I would find some way of mocking the self-proclaimed "best job in the world," but I don't think anyone would argue the merits of this gig. Check out the job description:
The role of Island Caretaker is a six-month contract, based on luxurious Hamilton Island in the Great Barrier Reef. It’s a live-in position with flexible working hours and key responsibilities include exploring the islands of the Great Barrier Reef to discover what the area has to offer. You’ll be required to report back on your adventures to Tourism Queensland headquarters in Brisbane (and the rest of the world) via weekly blogs, photo diary, video updates and ongoing media interviews. On offer is a unique opportunity to help promote the wondrous Islands of the Great Barrier Reef.
It looks like the contest is over (for now), but check out the full description if you want to try to take over in a few months.
