According to Burke & Wills Web Dost Mahomet participated in two further exploration expeditions under the command of A.W.Howitt. After being seriously injured by a camel in 1862 he returned to in Menindee where he worked for the town’s Chinese baker, Ah Chung. He died in 1880.
However, to my surprise, I discovered that there was a second “Afghan” cameleer named Dost Mahomet living and working in Australia in the nineteenth century. It is this second Mahomet who is described in detail in Wikipedia.
He arrived in Western Australia in the 1890s and lived and worked around the mining areas of the Pilbara and Murchison in Western Australia. There is quite a bit of information about his life, career and family in the entry, including his marriage to a European woman and eventual murder in 1909.
Both died at a relatively young age, but even for the times, it seems they each had an eventful life.
