Traditional land of the Bediagal people, Belmore was once all forest. Early European settlers cut the timber for firewood and later for railway sleepers, and farmed crops and poultry. In 1869 the district was named Belmore in honour of the new governor of New South Wales. When the railway came through in 1895, subdivision accelerated and after World War I surburban development was rapid. Migration and home units have changed Belmore since the 1960s.
