Australia ? Trouble struck paradise this week when a British man who has the “Best Job in the World” as the caretaker of a tropical Australian island was stung by a potentially lethal jellyfish.

Ben Southall — who won a contest to blog for six months about life on Australia’s Hamilton Island to promote tourism — wrote Tuesday that he was lucky to have survived his brush with the extremely venomous Irukandji jellyfish.

Earlier this week, Southall was getting off a Jet Ski in the ocean when he felt “a small bee-like sting” on his arm. When he later noticed a tingling in his hands and feet, island staff took Southall immediately to the doctor.

He was given pain medication and slept off the venom’s effects overnight.

The 34-year-old former charity worker bested nearly 35,000 applicants from around the world for the dream assignment that started in July to swim, explore and relax on Hamilton Island in the Great Barrier Reef while writing a blog to promote the area and earning a salary of $120,000.
