Norman Tindale estimate Nimanburu tribal lands to extend over roughly 1,200 square miles (3,100 km2) from the King Sound coast, around Repulse Point southwards to the swamp plain where the Fraser River debouches into the sea. Their inland extension ran as far as the headwaters of that river.[1]
People
Despite being territorially a coastal people, the Nimanburu refrained from seafaring, and were not known to employ rafts as other contiguous groups in the King Sound did.[1]
