Located about 15 kms north-east of Coober Pedy is the longest continual construction in the world, ‘The Dog Fence’, stretching some 5,400 kms. The fence starts east of Surfer’s Paradise in Queensland and winds it way north of Ceduna in the Great Australian Bight and is two and a half times longer than the Great Wall of China snaking across the outback . It was erected to keep out hostile invaders, to stop dingoes, Australia’s wild dogs and top predators, from killing sheep.
