What are feral deer?
Deer are not native to Australia. They were introduced to New South Wales as domestic livestock with European settlement.
Five species of deer have established feral populations in New South Wales:
- fallow deer (Dama dama)
- red deer (Cervus elaphus)
- sambar deer (Rusa unicolor)
- chital deer (Axis axis)
- rusa deer (Rusa timorensis).
A sixth species, the hog deer (Axis porcinus), has been recorded in New South Wales but established populations are unknown.

Why are deer a pest?
Deer have a range of major negative impacts in our parks and reserves because they:
- destroy native plants by trampling plants, grazing on them and ringbarking young trees – in the Royal National Park, they have had a major impact on the variety and abundance of plant species
- foul waterholes due to wallowing behaviour of some species
- cause soil erosion due to impacts of hard hooves in sensitive areas
- have the potential to transmit diseases such as foot-and-mouth disease
- spread weeds
- increase the risk of accidents and transport disruption due to collisions with vehicles and trains.
Herbivory and environmental degradation caused by feral deer has been listed as a key threatening process in New South Wales by the NSW Scientific Committee.
Managing deer in our national parks
The National Parks and Wildlife Service (NPWS) is responsible for the management of feral deer in our national parks. This is important not only for the protection of our native species and environment but for agricultural and urban areas close to our parks.
Feral deer can pose a threat to park neighbours and agriculture by competing with livestock for grazing resources, dispersing weeds, damaging crops and fences, and potentially spreading disease. In parkland close to urban areas, wild deer can pose a risk to drivers and can damage private gardens and public amenities.
As deer are widespread, management focuses on reducing impacts in priority areas. Management of deer for the protection of threatened species is prioritised through our regional pest management strategies and Saving our Species (SOS) program.
Deer control is undertaken using aerial shooting and ground shooting. NPWS shooting programs have been developed in consultation with RSPCA NSW to ensure that they are as effective, safe and humane as possible.
Report pests
Widespread pest animals should be reported to your Local Land Services.
Sightings of unusual animals should be reported to the Department of Primary Industries and Regional Development via the website or by phoning 1800 680 244.
