You’ll find the longest fence in the world in Australia, the dingo fence. With it’s over 5300 km it’s one of the world’s longest man-made structures. It was built back in the 1880s originally as a rabbit proof fence but it was more successful at keeping out pigs, kangaroos, emus and brumbies. In 1914 it was converted into a dog-proof fence used to keep the continent’s wild dog at bay and protect the sheep being grown for wool and meat production.
The fence stretches across southeast Australia and in Queensland, where it stretches for 2500km, it is called the Barrier Fence. It then joins the Border Fence in New South Wales, and travels another 584km. This is finally connected to the Dog Fence, 2225km of fence in South Australia. The whole structure is known as the Dingo Fence.
The fence is 180cm high made of wire mesh, and extends for 30cm underground. The fence line on both sides is cleared to a 5m width. Star pickets are spaced every 9m.
