Coleman River
From its source under Lapunya Mount in the Great Dividing Range, around eighty kilometres south of Coen, the Coleman River flows south past the Curlew Range before turning west through Bakanh, Kunjen, Yir Yoront and Thaayore country to discharge into the Gulf of Carpentaria between the Mitchell River's mouth and the settlement of Pormpuraaw to the north.
Over its 399-kilometre course, six tributaries, including the King and Lukin Rivers, join the Coleman, which drains a sparsely settled 737.6 square kilometre catchment that includes the abandoned mining settlement of Ebagoola.
William Hann named the river in 1872. His journal does not explain the origin of the name.
