Invasive animal species in Australia

A brumby is a free-roaming feral horse in Australia. Although found in many areas around the country, the best-known brumbies are found in the Australian Alps region. Today, most of them are found in the Northern Territory, with the second-largest population in Queensland. A group of brumbies is known as a "mob" or "band".
