Tasman Island is an oval island, with an area of 1.2 km2, in south-eastern Australia. It is part of the Tasman Island Group, lying close to the south-eastern coast of Tasmania around the Tasman Peninsula, and is in the Tasman National Park. It is a plateau surrounded by steep dolerite cliffs, with its highest point 300m and an average plateau height of 280m. It is the site of the Tasman Island Lighthouse and weather station, which has been automated since 1976 and unmanned since 1977.
It is also very, very cold 😉
