The Ngarlawongga were the people who inhabited the area of the headwaters of the Ashburton and Gascoyne rivers, going south to the vicinity of the Three Rivers and Mulgul. Their eastern extension ran to Ilgarari. In Norman Tindale's estimation, their tribal territories covered some 8,700 square miles (23,000 km2).[1]
On the Ngarlawongga's boundaries, to their immediate north were the Mandara, then, running clockwise, the Wirdinya north-east, followed by the Wardal, and the Madoitja south/southeast and the Watjarri to their south-west. The Ninanu lay on their western flank, below the northwestern Inawongga.[2][3]
People
The Australian writer Katharine Susannah Prichard's 1929 novel of interracial love, Coonardoo, was written directly after her stay among the Ngarlawongga while resident on McGuire's pastoral station, which was run by local Aboriginal people. She called them Gnarler and found the Ngarlawongga both "poetic" and "naive".[4]
