About East Arm

East Arm is the centre of marine services and development in Darwin Harbour, with large gas industry development and the NT’s main port on its shores.

East Arm receives urban stormwater runoff from the city of Darwin and there is a small discharge of treated wastewater from the Berrimah plant into Bleeser’s Tidal Creek.

Large areas of mangroves have been cleared for industrial development alongside East Arm. However, intact mangrove habitats still remain along approximately half the coastline of East Arm.

Part of the foreshore is bounded by Charles Darwin National Park.
