As the Afghan cameleers increasingly travelled through the inland, they encountered a diversity of Aboriginal groups. An exchange of skills, knowledge and goods soon developed. Some cameleers assisted Aboriginal people by carrying traditional exchange goods, including red ochre or the narcotic plant pituri, along ancient trade routes such as the Birdsville Track. The cameleers also brought new commodities such as sugar, tea, tobacco, clothing and metal tools to remote Aboriginal groups. Aboriginal people incorporated camel hair into their traditional string artefacts, and provided information on desert waters and plant resources. Some cameleers employed Aboriginal men and women to assist them on their long desert treks. This resulted in some enduring partnerships, and several marriages.
