Feral animals continue to threaten livestock, wildlife, flora & fauna right across Australia. The most effective solution is exclusion fencing because it can act as a physical barrier against digging, climbing & jumping feral threats. Conservation fencing will only be effective if it is designed, built & maintained using proven fencing products & solutions. Before making a final decision on your conservation fencing needs, talk to your local Waratah fencing representative.

Steel fencing systems
- Fabricated and netting fences with aprons are likely to afford the highest level of protection because the mesh itself is almost impenetrable (if correctly installed & maintained).
- wire netting aprons prevent feral animals from pushing or digging beneath a fence.
- floppy tops fences are the only fence designed to exclude cats & foxes.
- Cheap, poorly manufactured steel fencing products can be less durable.
Electric fencing systems
- Upfront material cost may be cheaper, but ongoing maintenance can be more expensive.
- Conditioned avoidance of electric fences has been demonstrated for a variety of species.
- to maximise the effectiveness of electric wires in exclusion fences the wires should form, or be used in conjunction with, a sufficiently challenging physical barrier.
- Often feral species can endure numerous shocks before developing avoidance behaviour. They also can often outsmart them by jumping or digging under the electrics.
- Repairing electrical faults & shorts is a regular maintenance requirement.
- Continual monitoring is required meaning this 'cheaper alternative' could become more costly then first planned.
Timber & steel fencing systems
- Treated pine posts can be cheaper than galvanised steel posts.
- In corrosive environments timber posts can be a more durable option.
- Timber posts provide a convenient platform for animals, particularly cats, foxes and goats to jump to. They also provide a excellent climbing surface.
- Timber posts grades vary considerably, potentially reducing the life of a fence and can therefore be less durable than galvanised steel posts.
- Timber will burn in most bush or grass fire prone conditions.

Mallee Cliffs National Park
In partnership with the NSW Government, AWC has constructed a 37.2 kilometre feral predator-proof fence within Mallee Cliffs National Park, creating a 9,570 hectare exclosure of ecologically significant bushland which, once cleared of predators, will be home to at least 10 regionally extinct mammal species as part of an ambitious rewilding program. The program began in October 2019 with the release of the Greater Bilby into a 480 hectare, specially-designed breeding zone.

Newhaven wildlife sanctuary
AWC’s ambitious project to restore central Australia’s lost biodiversity at Newhaven Wildlife Sanctuary has reached a new milestone – the eradication of all feral predators from the 9,400-hectare fenced area, making Newhaven home to the largest feral-free area on mainland Australia.
