Canada and Australia feel the squeeze in wake of Chinese economic slowdown

Iron and oil producers proved resilient during the crash of 2008-09 but are now struggling as commodities prices decline

In the mining town of Port Hedland, 1,500km north of Perth, modest prefabricated homes called fibro shacks, which were changing hands for more than A$1m four years ago, are now failing to find a buyer at a third of the price. Apartment blocks hurriedly tacked together by developers at the peak of the country's boom stand empty, because their promised supply of "fly-in-fly-out" mineworkers has dried up, along with the jobs they were brought in to do.
