It is part of the Myall Lakes National Park. Archaeology indicates that the certain ancestors of the Worimi people inhabited the island for an otherwise apparently indeterminate period of two thousand years, and whatever name those people may have had for the island itself remains unknown. It lay within the territory of the Garrawerrigal branch of the Woromi. "Garrawerrigal" meant "the people of the sea", from garoowa=sea. Niritba was "the home of the mutton bird" in their language.
