The only word recorded for the 'bush around the third river' (Sisters Creek) between the coast and plains, told to Robinson when he and his group camped the night in this place on 25 July 1830. On the same day he was also told the name mayntranga (Detention River), and on the 26th the names of nearby pinmatik (Rocky Cape) and tuynplinuk (Table Cape). Tanaminawayt, Pintawtawa, and Nikaminik, men from the neighbouring Cape Grim/Robbins Island area, were among his group of Aboriginal guides. The north western language area extended from Table Cape to Circular Head (Stanley), to Cape Grim/Robbins Island and down the west coast to around Macquarie Harbour: people in these areas spoke either the same or similar dialects, understood each other clearly and shared much vocabulary. Sisters Creek (and the bush around it), between Stanley and Table Cape, is within the north west language area.
