I have visited Port Hedland on many occasions, it's mostly a mining town with Port facilities to export iron ore and other minerals and boasts the purest salt production in the world. Also famous for it's 5km long trains carting ore to the continuous line of ships waiting offshore. In it's heyday it was the most expensive place to rent or stay in Australia.
The landscape is predominantly a rusty red with stilted trees and colourful wildflowers during certain seasons. Only once you start travelling south towards Newman and the major mine sites does the countryside get really interesting.
