A Drover in Australia is a person (Stockman) who takes cattle over long distances, usually during a drought or season change in search of green pastures on which the cattle can feed. Droving was extremely popular in the Kosciuszko National Park and Alpine National Park areas until the areas became National Parks. The Drovers would often bring cattle from the lower pastures to the fresh green pastures for the summer months.
