Feral deer impact natural environments by eating, ringbarking, rubbing against and trampling native plants and creating wallows. This habitat destruction can have flow on effects to other fauna that are sustained by healthy habitats. Feral deer also compete for food with native herbivores such as kangaroos and wallabies.

Feral deer impact agricultural production by eating pasture, crops and forestry saplings and damaging fences and infrastructure. They can also carry diseases and parasites that can be transmitted to livestock.

Feral deer impact Australians in peri-urban areas (the areas between rural and urban landscapes) where they can cause vehicle collisions and damage to parks, gardens and revegetation plantings. Males can be aggressive to people and domestic animals during deer mating seasons and feral deer are also a potential reservoir for human disease (e.g. COVID19).

Feral deer on private property may also attract illegal poaching, resulting in trespassing, illegal use of firearms and damage to properties. Feral deer also damage Traditional Owners’ cultural sites through loss and fragmentation of valued living landscapes, scar and signal trees and loss of culturally important trees such as Kurrajong.

DeerScan enables you to record new (and historical) observations of deer in your local area:


DeerScan is a free resource for landholders, landcare groups, community groups, local Councils, professional pest controllers and biosecurity groups. It has been designed to map and monitor deer in your local area by:

  1. Mapping sightings and evidence (e.g. photos & prints)
  2. Reporting damage (e.g. browsing of trees)
  3. Documenting control activities (e.g. ground shooting)

FeralScan is committed to protecting users’ data, location and information, with all DeerScan information managed securely and discreetly as described in our privacy policy. Exact locations of sightings, damage reports or control activities will not be visible to the public.

You can access DeerScan via www.deerscan.org.au or download the ‘FeralScan’ App and follow the deer prompts.

The National Feral Deer Action Plan is focused on supporting farmers, communities, organisations and government agencies to stop the spread and impacts of feral deer.

The final plan was released in August 2023 and aims to support farmers, communities, organisations and government agencies in halting the spread and impacts of feral deer. The development of the Plan has been funded by the Australian Government, in partnership with Centre for Invasive Species Solutions and the Department of Primary Industries and Regions South Australia.
