A jackaroo is a young man (feminine equivalent jillaroo) working on a sheep or cattle station, to gain practical experience in the skills needed to become an owner, overseer, manager, etc.[1][full citation needed] The word originated in Queensland, Australia in the 19th century and is still in use in Australia and New Zealand in the 21st century. Its origins are unclear, although it is firmly rooted in Australian English, Australian culture and in the traditions of the Australian stockmen.
