The Dingo Fence or Dog Fence is a pest-exclusion fence that was built in Australia during the 1880s and finished in 1885, to keep dingoes out of the relatively fertile south-east part of the continent (where they had largely been exterminated) and protect the sheep flocks of southern Queensland. It is one of the longest structures on the planet, and the world's longest fence. It would eventually stretch 5,614 km (3,488 mi) from Jimbour on the Darling Downs near Dalby through thousands of miles of arid country to the Eyre peninsula on the Great Australian Bight. It was only partly successful; Dingoes can still be found in parts of the southern states to this day, and although the fence helped reduce losses of sheep to predators, this was counterbalanced by increased pasture competition from rabbits and kangaroos.
