In 1819 Wentworth published the first book written by an Australian: "A Statistical, Historical, and Political Description of the Colony of New South Wales and Its Dependent Settlements in Van Diemen's Land, With a Particular Enumeration of the Advantages Which These Colonies Offer for Emigration and Their Superiority in Many Respects Over Those Possessed by the United States of America", in which he advocated an elected assembly for New South Wales, trial by jury and settlement of Australia by free emigrants rather than convicts.
