6 species of deer exist in Australia, 4 of which are well established in Victoria. These are the Sambar, Fallow, Red, and Hog Deer. Deer are classified in Victoria as wildlife and so are protected. Authorisation is required to control or hunt deer. Currently, shooting is one of the only effective methods available for deer control.
Deer can have negative impacts by damaging fences, trampling and eating native vegetation, and competing with native fauna for food. Collisons with cars are also a major impact of deer, causing serious traffic incidents.
You can report sightings of deer here, using the FeralScan site.
