Port Hedland (Kariyarra: Marapikurrinya) is the second largest town in the Pilbara region of Western Australia, with a population of approximately 14,000, including the satellite town of South Hedland, 18 km away. It is also the site of the highest tonnage port in Australia. Port Hedland has a natural deep anchorage harbour which, as well as being the main fuel and container receival point for the region, was seen as perfect for shipment of the iron ore being mined in the ranges located inland from the town. The ore is moved by railway lines from four major iron ore deposits to the east and south of Port Hedland area. In August 2010 the port exported 13.6 million tonnes of iron ore. Other major resource activities supported by the town include the offshore natural gas fields, salt, manganese, and livestock. Grazing of cattle and sheep was formerly a major revenue earner for the region but this has slowly declined. Port Hedland was also formerly the terminus for the WAGR Marble Bar Railway which serviced the gold mining area of Marble Bar. Located between Port Hedland and South Hedland are the large salt hills of Dampier Salt, a subsidiary of Rio Tinto. These large mounds have almost become a tourist attraction in their own right.
