How does a fence protect native plants and animals

Friday 2 December, 2022

Wilsons Promontory National Park will become a 50,000-hectare climate change safe haven – where Victoria’s rich wildlife and habitats are freed from the pressures of introduced species, thanks to the Wilsons Prom Sanctuary project.

Many of Victoria’s native plants and animals are facing challenges due to climate change, loss of habitat, and predation from feral pests.

So, you might wonder - how does a fence help?

Put simply, the fence will keep unwanted animals out and protect vulnerable species, giving them the best chance to survive.

This can get complicated when some of the undesirable animals are clever and will try to jump, dig under or swim around the fencing.

There are many things to consider when designing this fence, which is why Parks Victoria is taking inspiration from existing projects, wildlife experts, environmental scientists, and engineers, to ensure that the Prom Sanctuary Fence is built right.

Parks Victoria is working with Traditional Owners in the protection of Aboriginal Cultural Heritage in this bio-cultural landscape.

Newhaven Wildlife Sanctuary, Northern Territory

Quick stats


261,501 hectares (100,000 protected by fencing)

Fence length:

44 kilometres

Protected species: 604 native plant species
294 native animal species


Newhaven Wildlife Sanctuary is one of Australia’s largest non-government protected areas. A hotspot for central Australian wildlife, Newhaven is a popular birdwatching destination supporting 174 species of birds.

Newhaven's 44-kilometre fence has created the world's largest feral cat eradication project, providing safe habitat for threatened animals including The Great Desert Skink.

Marna Banggara, South Australia

Quick stats


170,000 hectares (150,000 protected by fencing)

Fence length:

25 kilometres

Protected species:

659 native plant species
258 native animal species


Marna Banggara, meaning ‘healthy, prosperous Country’ in Narungga language, is a collaborative program to restore ecosystems and return locally extinct species back to South Australia’s Yorke Peninsula. The ambitious project is unique as the reintroduced species are making their home within a working landscape, next door to farms, popular beaches and towns.

Its 25-kilometre fence is supported by a feral predator control program which provides refuge for threatened creatures including brush-tailed bettongs and southern brown bandicoot who are at risk from feral cat and fox predation.

Marna Banggara is jointly funded through the Australian Government’s National Landcare Program, the Northern and Yorke Landscape Board, the South Australian Department for Environment and Water, WWF-Australia and Foundation for National Parks & Wildlife, in partnership with the Narungga Nation Aboriginal Corporation.

Scotia Wildlife Sanctuary, New South Wales

Quick stats


64,969 hectares (8,000 hectares fenced)

Fence length:

56 kilometres

Protected species: 437 native plant species
267 native animal species


Located in the Murray-Darling Basin, Scotia Wildlife Sanctuary is home to some of the largest remaining populations of threatened mammals like the Woylie.

Thanks to careful land management and a 56 kilometre fence, the sanctuary contains one of the largest fox and cat-free areas on mainland Australia and represents a chance for threatened species to repopulate.

For more information, visit Australian Wildlife Conservancy.

Project Eden in Francois Peron National Park, Western Australia

Quick stats


52,000 hectares

Fence length:

3 kilometres

Protected species: 158 native plant species
145 native animal species


Known as the ‘desert on the edge of this sea,’ this national park is on the traditional Country of the Malgana people and lies within the Shark Bay World Heritage Area.

In 1995, a fence was constructed across the narrow neck of Peron Peninsula to prevent feral animals from entering. Feral animal control works have helped plants bounce back and create a safe habitat to re-introduce native species like the Rufous Hare-Wallaby.

For more information, visit Project Eden.

Wilsons Prom Sanctuary, Victoria

This will be Victoria’s largest conservation sanctuary, protecting an incredible diversity of ecosystems and allowing the Prom to be enjoyed in its full glory for many generations to come. 

Quick stats


50,000 hectares

Fence length:

To be determined

Protected species: 101 threatened native plant species
49 threatened native animal species


Fence projects across Australia are helping to protect vital habitats and vulnerable species.

The Prom Sanctuary will reduce threats to native plants and animals found at the Prom and provide a safe haven for species that may be on the brink of extinction.
