The Deua River is a scenic freshwater stream flowing through New South Wales, Australia, draining the eastern slopes of the Great Dividing Range south of Braidwood and winding its way to the coast near Moruya. The river passes through the Araluen Valley and is fed by tributaries including Araluen Creek, creating a diverse aquatic environment that supports a range of native and introduced fish species. The catchment also supplies a significant portion of water for the Eurobodalla Shire, reflecting the river's ecological and community importance. The surrounding landscape is characterized by the rugged terrain of the Great Dividing Range, with the river transitioning from upland reaches near Braidwood down through valley corridors toward the coast.
