The brumby is a breed of horse from where?

'Brumby' is a general term for an Australian wild or feral horse. Brumbies are not a specific breed of horse, but descendants of horses that were released, or that escaped, into Australian bushlands when the early settlers arrived.

Brumbies are found throughout Australia, from the harsh outback, to the coastal regions (and Fraser Island, the world's largest sand island), to the Alpine country of southern NSW and northern Victoria.
