Australia holds many world records, including the world’s longest fence, the dingo fence.

At 5,531 km (3437 miles), the dingo barrier fence stretches from eastern Queensland all the way to the South Australian coastline. The fence was erected in the late 1800s and early 1900s to protect cropland from rabbits. It was later modified to protect livestock, particularly sheep, from dingoes.

The dingo fence is still actively maintained. A levy is charged to graziers to fund wages for maintenance and patrol workers. In Queensland, the Wild Dog Barrier Fence Panel provides administrative assistance, as does the Wild Dog Destruction Board in New South Wales.

The dingo fence has stirred a long-running scientific debate about whether the exclusion of dingoes has a detrimental effect on ecosystems. One argument is that dingoes can keep in check smaller predators such as invasive red foxes and feral cats, in turn benefiting native species by reducing overall predation pressure upon them.
