Dog fence

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 in the world and is the world's longest fence. It stretches 5,614 kilometres (3,488 mi) from Jimbour on the Darling Downs near Dalby through thousands of kilometres of arid land ending west of Eyre peninsula on cliffs of the Nullarbor Plain above the Great Australian Bight near Nundroo. It has been partly successful, though dingoes can still be found in parts of the southern states. Although the fence has helped reduce losses of sheep to predators, this has been countered by holes in fences found in the 1990s through which dingo offspring have passed and by increased pasture competition from rabbits and kangaroos.

The 2,500 km (1,553 mi) section of the fence in Queensland is also known as the Great Barrier Fence or Wild Dog Barrier Fence 11. It is administered by the Department of Natural Resources and Water. The Wild Dog Barrier Fence staff consists of 23 employees, including two-person teams which patrol a 300 km (186 mi) section of the fence once every week. There are depots at Quilpie and Roma.

The Queensland Border Fence stretches for 394 km (245 mi) westwards along the border with New South Wales, into the Strzelecki Desert. The fence passes the point where the three states of Queensland, New South Wales and South Australia meet (Cameron Corner). At this point, it connects with the South Australian Border Fence, which runs for 257 km (160 mi) southwards along the border with New South Wales. It then joins a section known as the Dog Fence in South Australia, which is 2,225 km (1,383 mi) long.
