Background

  • From 1840 to 1907, up to 20,000 one-humped dromedary camels (Camelus dromedaries) were imported into Australia.
  • Camels were used for transport, exploration and in the goldfields—a male camel can carry up to 600 kilograms.
  • By 1930, camels had largely been replaced by motor and rail transport.
  • Some camels were destroyed, but most were simply released into the wild. Released camels thrived and bred prolifically in the dry remote areas of Australia.

Distribution and density

  • There may have been 800,000 camels in Australia before culling was introduced in 2009.
  • There are now about 300,000 camels due to culling and the effects of drought throughout central Australia in 2013.
  • Because of the large amount of damage they cause to pastoral infrastructure in Western Australia, feral camels are declared pests under the provisions of the Biosecurity Agriculture and Management Act 2007.
  • Western Australia is now home to the largest herd of feral camels in the world, with 45% of the nation's camels. Most camel herds are domesticated in other parts of the world.
  • In the Australian desert, camels may now out number red kangaroos by 100 to 1.

Camel biology and ecology

  • Camels can survive without water for long periods, and survive extreme dehydration without serious effects.
  • A camel can go up to a week with little or no food and water, and can lose a quarter of its body weight without impairing normal functions.
  • Camels can travel up to 70 kilometres a day. They range freely and are not territorial.
  • Camel populations have relatively few diseases and no natural predators.
  • They rarely starve as they can feed on more than 80 per cent of the available plant species in most areas.
    • Camels can eat up to 3.5 kilograms of food a day.
    • They graze on low shrubs or vegetation up to 3.5 metres above the ground—a larger range than any other herbivore in Australia.
  • A thirsty camel can drink up to 200 litres of water in 3 minutes.
  • Camels can live for up to 50 years.
    • They actively breed for 30 years of their life.
    • Cows give birth to a single calf every 2 years.
  • Female camels, cows, live in groups of about 30 with their calves.
    • Female groups are temporarily herded by a male bull during mating season
    • Male camels usually live alone or in bachelor groups of about 20 bulls.
    • When water and food is scarce, herds can reach up to 400 individuals.

Impacts

Wildlife and natural habitat

  • Camels pose a direct threat to areas of ecological significance, many of which are managed by the department.
  • Mobs of camels can quickly completely strip an area of vegetation by trampling and grazing.
  • They can drain or foul water points, affecting local wildlife that rely on these scarce desert water sources.

Damage to Aboriginal communities, cultural sites and rock holes

  • Camels can cause tremendous damage to Aboriginal ceremonial art and other cultural sites associated with rock holes by trampling and rolling.
  • Camels can overrun Aboriginal communities in their attempt to get to taps, wells and the water in air-conditioners.

Damage to pastoral infrastructure

  • Camels regularly move from undisturbed desert areas to pastoral leases during periods of drought in search of more permanent water, although they generally return to desert once conditions are favourable.
  • Camels can cause damage to stock fences for several hundred metres. They can also damage infrastructure at cattle watering points.

Potential hazard to remote motorists

  • Camels can pose a hazard on outback roads, which they use as paths to travel along.
