Bailgu traditional lands extended over 6,300 square miles (16,000 km2), according to Norman Tindale's estimate,[1] covering the upper Fortescue River, and taking in Roy Hill and eastwards beyond the Goodiadarrie Hills. Their northern extension ran as far as the Chichester Range scarp the Nullagine River divide. The eastern border ran to the western headwaters of the Oakover Davis rivers.[1] Their neighbours further down the Fortescue were the Niabali. Their boundary with the Yindjibarndi lay at Mandanaladji.[1]
History of contact
According to oral traditions handed down by the Bailgu, before the advent of the whites, they were dislocated from the salt marshs on the Fortescue river by pressure from the Panyjima tribe, which drove them further east. This narrative appears to be corroborated by the fact that among western tribes they were known as the Mangguldulkara (people of the marshes).[1]
