Nelson Marine Park is deep and remote. It lies 200 kilometres south of South Australia, beyond the edge of the continental shelf. The park encloses important habitats representative of the West Tasmanian Transition, and includes geological features such as plateaus, knolls and canyons. These features provide important hard substrate for benthic biota to attach, creating oases of biodiversity in an otherwise soft and muddy terrain. Nearer the surface, whales transit through the park on the way to and from their breeding and feeding grounds.

The park is located to the south-west of South Australian’s border with Victoria. It covers 6,123 square kilometres and is a Multiple Use Zone. – Parks Australia
