If you could use a break from the world, perhaps a prolonged stay on a remote Australian island is right up your alley. The Tasmania Parks & Wildlife Service is looking for a volunteer caretaker for an uninhabited island.
Six miles off the coast of Tasmania, Maatsuyker Island is pretty empty, save for Australia's southernmost lighthouse. The Parks service is looking for caretakers for six-month stints on the island, where they would track daily weather conditions in addition to maintenance of grounds, buildings and plant and equipment.
Be sure to bring a lot of books, though—there's no internet access and the only way to get to and from the mainland is by helicopter in an emergency.
