Have you ever driven or walked by a fence that seems to go on forever? Well, long fences have been used by ranchers and large-scale farmers for centuries to keep unwanted animals out of their property and their crops and animals safe.

The longest fence in the world, also known as the dingo fence, is located in Australia and stretches for 3,437 miles (5,531 kilometers). The fence is 6ft high plus 1ft underground and was built to keep certain pests in Australia, mostly rabbits and wild dogs (dingoes), from the fertile lands.

The longest fence in the world is the longest border or barrier built by man and in this article, we’ll discuss the Who, why, and when questions concerning the longest fence in the world.

The official name of the longest fence in the world is The State Barrier Fence of Western Australia. The name explains the fence as a barrier between the western and the southeastern side of Australia.

However, this popular spot is commonly known and referred to as the dingo fence but this has not always been so.

The fence is also known as the following titles;

  • The Rabbit – Proof Fence
  • The State Vermin Fence
  • The Emu Fence

The longest fence in the world was named during these times for the animals and pests it was proposed to keep out.

Who built the Longest Fence in the world?

The longest fence in the world stretches for 3437 miles and was an effort by the Australian government-backed heavily by the community of Australian farmers in the late 1800s.

The fence was built to keep out the pests that were killing their sheep, destroying their livelihoods, and just plain nuisance.

The sheer length of the fence depicts that it wasn’t an easy task especially as the fence is unbroken throughout its length. However various sections were built separately in the late 1800s and later joined in 1946 to 1950.

Why was the Longest Fence in the World Built?

The longest fence in the world might seem like a wonder or a visitor’s attraction while visiting Australia but the fence was built to serve a very necessary purpose at the time. Here are some of the reasons why the fence was built.

  • To keep rabbits away.

Rabbits might be herbivores but a large number of rabbits meant that a lot of the grazing grassland was being devoted leaving inadequate amounts for the sheep. Building the border helped control the rabbit population.

  • Protect farm animals from wild dogs (dingoes).

One of the major reasons for building the longest fence in the world was to stop the attack on farm animals by dingoes. Dingoes are wild dogs indigenous to Australia and are one of the largest predators in the country.

  • To protect the sheep.

Australia is known for having more sheep than people and the majority of farmers rear these farm animals. Dingoes are one of the biggest predators of the local sheep and the Fence was constructed to protect the sheep.

  • To reduce the number of pests on Australian farmers and their farmlands.

Farmers would lose thousands of sheep to dingoes and grasslands to rabbits every year before the fence was built and that number dropped significantly after the border was erected.

How Long did it Take to Build the Longest Fence in the world?

Building a regular fence might take a weekend or two. However, when you’re talking about a 3437-mile fence, the time range changes drastically.

Construction of the longest fence in the world began in 1859 and was completed in 1885. This means that it took twenty-six years (26 years) for the dingo fence to be constructed.

However, the fence was built in sections. It was connected to form the unbroken barrier called the dingo fence from 1946 to 1950.

What material was used to build the longest fence in the world?

Building an unbroken fence of over 3,000 miles requires durable and reliable materials. Although the fence was built a century ago and has had to undergo extensive maintenance, the original materials used to build the fence were of good quality and durable.

The major material used in the construction of the longest fence in the world is wire mesh but some areas along the South Australian Border Fence have multi-strand electric fences.
