George Leitch established himself as a comedian between 1867 and 1874 in the English provincial towns and appeared in London for the first time in 1876. In 1881 he went to South Africa, and to Australia in 1882. He remained in the Australasian region until the late 1890s in association with such companies as Williamson, Garner and Musgrove, the MacMahon Bros and Brough and Boucicault.
Among the works likely written during his time in Australia and New Zealand are: Two Brothers ; Or, Suitors to Grind (ca. 1895) and The Old Homestead (ca. 1895). Leitch also adapted Marcus Clarke's For the Term of His Natural Life as a five-act play (a draft manuscript is held by the University of Queensland's Fryer Library).
