To protect the World Heritage-listed Ningaloo Coast in Western Australia’s north-west region, the Australian Maritime Safety Authority (AMSA) to establish an area ships should avoid. A new AMSA Marine Notice will recommend ships keep at least two nautical miles from the edge of Ningaloo Reef at its narrowest part, and between eight and 12 nautical miles from the reef along the remainder of the Ningaloo Coast section to reduce the risk of shipping accidents and help protect the World Heritage listed region from ship-sourced pollution.
