The headwaters of the river are in the Mitchell Ranges and the river flows in a southerly direction between Mount Ramsay and Mount Fleming and through Fairy Glen then down onto a plain then cuts through Bath Range under Mount Rankine and veering eastward. The river then passes the Aboriginal communities of Marrkalawa and Andanangki the past the Coast Range and discharges into Blue Mud Bay and the Gulf of Carpentaria and the Arafura Sea.

The estuary formed at the river mouth is in near pristine condition with a tidal delta. The estuary at the river mouth occupies an area of 29.5 hectares (73 acres) of open water. It is river dominated in nature with a tide dominated delta with a single channel and is surrounded by an area of 30.9 hectares (76 acres) covered with mangroves.
