Australia's Unknown (1915)

This silent travelogue chronicles Francis Birtles' and Frank Hurley's 6,000-mile motorized expedition through the unmapped Australian wilderness. Filmed over four months in 1914, it serves as a historic natural and ethological study across Central Queensland, the Gulf of Carpentaria, and the Northern Territory. The surviving written records detail outback landscapes, swamps, and water-lily lagoons. In addition to flora, it extensively records fauna including crocodiles, alligators, snakes, wallabies, wild boars, camel teams, lizards, pelicans, and various bird species. This documentary also provides footage of Indigenous people and their practices, capturing ceremonial dances, fish spearing, hunting methods, traditional corroborees and a native tree burial. This film is considered entirely lost.
