The Jeannie River is a significant waterway in Far North Queensland, flowing into the Coral Sea near Howick Island. It forms part of the broader Jeannie and Endeavour River Basins, a system that includes both freshwater and estuarine environments. The catchment is characterized by distinct wet and dry seasons, shaping its hydrology and ecology. The river's waters are managed with specific environmental values in mind, and a portion of its coastal area falls within the Starcke River declared Fish Habitat Area, indicating its importance for marine life.
