Grahway is a bounded rural locality, and cadastral parish,[2][3] 100 kilometers south of Nyngan, New South Wales.

The original inhabitants of the area were the Wiradjuri Australian aboriginal tribe, though anthropologist Norman Tindale believed the area around "The Overflow" was traditional lands of the neighboring Wangaibon a tribe of the Ngiyambaa peoples.

Thomas Mitchell explored the area around the Bogan River in 1835.

The sheep station "The Overflow" made famous with the poem Clancy of the Overflow by Banjo Paterson,[7][8] is located 1 km south of the Parish.
