Dog Fence

The 5,400 km dog fence protects sheep grazing districts from wild dogs and dingoes. It stretches eastwards across South Australia from the Great Australian Bight near Fowlers Bay, borders the grazing properties into New South Wales and then turns north and east across Queensland to the Darling Downs. It is the longest continuous fence in the world.

The fence protects sheep graziers and their livestock from wild dogs and dingoes on the southern side of the fence. It is a crucial part of supporting and protecting the South Australian sheep industry.

It was established under the Dog Fence Act 1946. For more information on the history of the Dog Fence (and other control fences) visit the History of Agriculture website.

Dog fence upgrade cost benefit analysis

The State Government and the South Australian Dog Fence Board commissioned BDO EconSearch to undertake a cost benefit analysis for the upgrade of the Dog Fence in South Australia.

The report and it’s key findings are now available.


The Dog Fence Board (the Board) is the governing body set up to administer and manage the approximately 2,150 kilometre long South Australian section of the Dog Fence. Local dog fence boards (Local Boards) are established to patrol and maintain the Dog Fence. There are currently 6 Local Boards in South Australia, each with responsibility for a section of the fence.

The fence has been maintained, re-aligned, and upgraded since 1947.

The Board ensures that the fence is regularly patrolled and maintained with funds received from:

  • A levy paid by properties greater than 10 square kilometres in unincorporated areas, inside of the Dog Fence. The levy also applies to properties in incorporated areas that are close to the unincorporated areas. This levy is enforced by the Dog Fence Act 1946. The lands to which the levy applies can be seen in this list where Dog Fence rates are payable, or on this map showing where Dog Fence rates are payable.
  • A levy paid on all sheep sold in South Australia. This levy is collected for the Board by the Sheep Advisory Group of SA (SASAG).
  • The South Australian Government, which matches the above levies on a dollar for dollar basis.
  • A levy paid by properties outside the Dog Fence, where they utilise the fence as a boundary for their lands.

Maintenance and inspection

As fence owners, Local Dog Fence Boards have contractors do fortnightly patrols to:

  • undertake repairs
  • place poison baits along the fence line
  • destroy dogs sighted in the vicinity of the fence.

The Board also inspects approximately half of the fence every year to:

  • identify sections that need updating or replacing
  • prioritise and assign capital funds to sections of the fence.

Reports on the Dog Fence

The Dog Fence Board reports on the condition of the Dog Fence and the activities of the Inspector of Dog Fences every 4 months.


The Dog Fence in South Australia is owned by:

  • Some pastoral lessees, whose properties are on the southern side of the fence and adjacent to it.
  • The Local Dog Fence Board maintains the Dog Fence on behalf of many pastoral lessees inside the Dog Fence.

All Dog Fence owners must:

  • maintain and keep the fence dog proof
  • destroy wild dogs in the vicinity of the fence.

Dog Fence Board

Members of the Dog Fence Board are appointed under the Dog Fence Act 1946. The current Board members were appointed on 6 August 2015 and will retain their positions on the Board until 13 July 2019.
