At the completion of the project in 2013, the Australian Feral Camel Management Project had reduced the feral camel population by 160,000 camels. This includes over 130,000 through aerial culling, 15,000 mustered and 12,000 ground-culled (shot from vehicle) for pet meat. It estimated around 300,000 camels remained, the population increasing 10% per year. The largest individual aerial cull operation was conducted in mid-2012 in the south-west of the Northern Territory. It employed three R44 helicopter cull platforms in combination with two R22 helicopter spotting/mustering platforms. It removed 11,560 feral camels in 280 operational hours over 12 days, over 45,000 square kilometres, at a cost of around $30 per head.
