Nambucca River, an open and trained mature wave dominated barrier estuary, is located in the Mid North Coast region of New South Wales, Australia.
Nambucca River rises below Killiekrankie Mountain on the Dorrigo Plateau, part of the Great Dividing Range, and flows generally east southeast, joined by four tributaries including Taylors Arm, before reaching its mouth at the Tasman Sea of the South Pacific Ocean, at Nambucca Heads. The river descends 594 metres (1,949 ft) over its 87 kilometres (54 mi) course; adjacent to the towns of Bowraville, Macksville and Nambucca Heads.
The Nambucca River area has a fine subtropical climate, high rainfall and fertile volcanic soils. It was originally covered by rainforest, much of which has been cleared, although some rainforests remain in several national parks and reserves. The lowlands along the river are used for farming.
