De Witt Island, also known as Big Witch, is an island located close to the south-western coast of Tasmania, Australia. The island is the largest of the Maatsuyker Islands Group, and comprises part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site. The island is listed on the Australian Register of the National Estate.〔 ==Location and features== De Witt Island lies some south of Louisa Bay, on Tasmania's south coast. The island is broadly triangular in shape, some across, with cliffs ranging from high to the south on all sides except a part of the central north coast. The highest parts of the island are located very close to the south coast, and enclose a north-facing basin. The island's summit is located very close to its southernmost point.〔 Although currently uninhabited, it has a long history of human usage, including logging and occasional habitation.〔Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa.
