The Arnhem Marine Park park lies off the coast of west Arnhem Land, and is a dynamic region with with localised upwellings. The gently sloping shelf within Arnhem Marine Park is topped with a number of pinnacles, and the dynamic habitats this geomorphology creates are of high commercial and conservation value. In addition to providing inter-nesting habitat for the threatened flatback turtle, this marine park is important for breeding species of seabirds such as the bridled tern and roseate tern.

The park is located north of Maningrida and adjacent to the Goulburn Islands. It covers 7125 square kilometres and is a Special Purpose Zone.Parks Australia

Arnhem ranges from less than 5 to 62 metres depth, with an average depth of 36 metres. The majority of the Park (67%) falls within the mesophotic zone (30-70 metres). [View on map]
