Gourt Home::Gourt :: Dingo Fence
The Dingo Fence or Dog Fence is a barrier that was built in Australia during the 1880s and finished in 1885, to keep dingos 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 5,320 kilometres from Jinbour on the Darling Downs near Toowoomba through thousands of miles of arid country to the Eyre peninsula on the Great Australian Bight. At the time, it was the longest man-made structure in the world. 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.
The 2500km section of the fence in Queensland is also known as the Barrier Fence or Wild Dog Barrier Fence. It is administered by the Department of Natural Resources and Mines. The Wild Dog Barrier Fence staff has 23 employees, with two person teams which patrol a 300km section of the fence once every week. There are depots at Quilpie and Roma. * (pdf)
It joins the Border Fence in New South Wales, where it stretches for 584km along Latitude 29. The fence passes the point where the three states of Queensland, New South Wales and South Australia meet (Cameron's corner), where there is a brass plate on the survey monument. It is known as the Dog Fence in South Australia, which is 2225km long. *
The fence is 6 feet (180cm) high made of wire mesh, and extends for 1 foot (30cm) underground. The fence line on both sides is cleared to a 5 metre width. Star pickets are spaced every ten yards (9m). At first it was unsuccessfully used to try and keep out rabbits, with the fence built originally as a rabbit proof fence in 1884. It was more successful at keeping out pigs, kangaroos, emus and brumbies. In 1914 it was converted into a dog-proof fence.
It seems that there are fewer kangaroos and emus on the north western side of the fence where the dingos are, suggesting that dingos impact the populations of those animals. * It has also been suggested that the large kangaroo populations in the south east have been caused by the fence, which have caused a larger problem due to eating grass and using up water than the dingos were. *
Parts of the Dingo Fence are lit at night by 86mm cold cathode fluorescent lamps which are alternately red and white. They are powered by long life photovoltaic cells which are charged during the day. *
The fence is held together by Gripples.
Journalist James Woodford travelled along the fence and wrote an account of his trip called The Dog Fence *
