The Australian Brumby was imported to Australia probably during the Australian Gold Rush of 1851. Many of these horses that were imported escaped from the mining settlements and ran wild in the scrublands. These horses became known as Brumbies. The Brumbies of the wild are no longer of good quality but have developed the survival instinct that has enabled them to withstand the climate and avoid the stockmen who hunted them. Some of these Brumbies have been caught and tamed, but many are too wild to be of any use. In the 1960s the population of the horses was a problem and even though many of these horses were being slaughtered as meat for pet food, a huge culling operation was organized. A herd of 8,000 Brumbies about 700 miles west of Brisbane were chased and shot at from vehicles and small aircraft. An estimated 17,000 Brumbies were killed on just three properties. After the public became aware of this, there was a global outrage and today the issue is still under discussion. There is definitely a problem with the population of the Brumbies and there is no use or demand for them in modern Australia. Today the Australian Brumby has spread all over the Australian outback.
