The Dingo Fence or Dog Fence is a pest-exclusion fence in Australia to keep dingoes out of the relatively fertile south-east part of the continent (where they have largely been exterminated) and protect the sheep flocks of southern Queensland. It is one of the longest structures in the world. It stretches 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. Geography The 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 Agriculture and Fisheries. The Wild Dog Barrier Fence staff consists of 23 employees, including two-person teams that patrol a section of the fence once every week. There are depots at Quilpie and Roma. The Queensland Border Fence stretches for 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 southwards along the border with New South Wales, these two sections are managed by the New South Wales Wild Dog Destruction Board. It then joins a section known as the Dog Fence in South Australia, which is long. Physical design The fence varies in construction. Mostly it is made of high wire mesh but some sections in South Australia comprise multi-strand electric fence. The fence line on both sides is cleared to a width. Sheep and cattle stations protected by the fence are exceptionally large. While varying in size, some stations can be larger than small countries. One station alone in South Australia lost over 11,000 sheep in a year due to dingo attacks before the completion of the fence. As recently as 1991, one station lost 3000 sheep in a year . Sheep farmers fought back by using poisoning, shooting, and eventually constructing the longest fence
