They are the cowboys of the Outback, the embodiment of Australia's frontier spirit.
But jackaroos, who spend their days on horseback mustering cattle and sheep, are being pushed out of the saddle by their female counterparts - jillaroos.
A record number of young Australian women are forsaking the comforts of city life to become jillaroos, a job that requires them to fix fences, check remote waterholes, and herd unruly mobs of livestock through some of the world's toughest terrain.
The women have been given a chance to enter what was until recently a staunchly male domain because outback 'stations', or ranches, are facing dire recruitment problems.
Lured by the prospect of tripling their wages, jackaroos are flocking to the mining industry, which is booming on the back of China's demand for raw materials to feed its surging industrial development.
With Australia's buoyant economy into its 17th consecutive year of growth, the country is experiencing its lowest unemployment in more than 30 years.
