Dampier is a major industrial port in the northwest of Western Australia. The port services petrochemical, salt, iron ore and natural gas export industries. Rio Tinto exports large volumes of iron ore through the port. North of Dampier lies the Burrup Peninsula, or Murujuga, which means “Hip Bone Sticking Out” in the Yaburrara language, which is home to what is believed to be the largest collection of petroglyphs (ancient rock art) in the world. The port of Dampier was opened in 1966, when the first iron ore from the Mount Tom Price mine was transported via the Hamersley & Robe River railway. The port has an annual loading capacity of 140 million tonnes of iron ore. It takes from 24 to 36 hours to load a ship at port.
