Government House Lake

Government House Lake is a saline lake on Rottnest Island in Western Australia. It is partly reclaimed on its southern shore, for the Rottnest Island Airport. Adjacent lakes are Pearse Lakes to the west, Serpentine Lake to the south west, and Herschell and Garden Lakes to the north.

The Government House Lake, and the other lakes of Rottnest are often mentioned in passing, in anecdotal reminiscences about the island.Various features have been constructed since European settlement of the Island in the 1800s. In the 1930s a stone jetty was constructed, with steps leading down to it cut into the limestone cliff. Apart from the airport it also had a war time railway, and recent tourist railway run south of its shore.
