The Heard Island and McDonald Islands (HIMI) Marine Reserve is located in Australia's remote subantarctic waters, approximately 4000 kilometres south-west of the Australian mainland and 1000 kilometres north of Antarctica.

The Reserve covers an area of approximately 65,000 square kilometres, and includes Heard Island and the McDonald Islands, the surrounding 12 nautical mile territorial sea, plus an extended marine area (including the seabed and subsoil to a depth of 1000 metres) which extends in parts to the 200 nautical mile Exclusive Economic Zone (EEZ) boundary.

Descriptions and diagrams of the zones within the Reserve are available from the Zoning page.
