Exploring the relationship between Aboriginal people and their land, Walya Ngamardiki was inspired by Silas Roberts' submission to the 1976 Australian Government inquiry on uranium mining. Silas, whose tribal name is Ngourladi, is an elder of the Allawa clan and was the first chairman of the Northern Land Council, established to assist Aboriginal people make land claims based on traditional ownership. The film, which moves from Arnhem Land in the north to Yuendumu in the centre, examines the importance of maintaining Aboriginal culture and laws and explains the reasons behind the land rights struggle.
