Mulgrave River
Sourced by runoff from the Bellenden Ker Range, and formed by the confluence of the East Mulgrave and West Mulgrave Rivers within the Wooroonooran National Park, the Mulgrave River flows through Yidinji Country to discharge into the Coral Sea via an estuary it shares with the Russell River approximately 40 kilometres south-southeast of Cairns.
The river's east and west branches rise west-northwest of Babinda below Mount Bellenden Ker's South Peak, merge, and flow north towards Little Mulgrave and through the Goldsborough Valley, passing Gordonvale's outskirts to cross the Bruce Highway before a 270° turn to the southeast sees it run roughly parallel to the highway past Aloomba, Fishery Falls and Deeral with the Malbon Thompson Range between the stream and the sea.
Volcanic activity that formed Green Hill northeast of Gordonvale redirected the Mulgrave from its former mouth in Trinity Inlet. However, river sediments above the Green Hill basalt flows, suggest the river may alternate between the two mouths according to the amount of wet season runoff.
The Goldsborough Valley was the location for the late 1870s Mulgrave gold rush.
