Course and features
Myall River rises of the southern slopes of Kyle Range within the Great Dividing Range, north northeast of Stroud, and flows generally south southeast then southwest, joined by tributaries including, before reaching its mouth within Port Stephens at Hawks Nest. Port Stephens then empties into the Tasman Sea of the South Pacific Ocean. The river descends 355 metres (1,165 ft) over its 92 kilometres (57 mi) course.
After flowing past the town of Bulahdelah, east of the small settlement of Nerong, the Myall River enters the most southern of the three Ramsar-protected Myall Lakes, Bombah Broadwater, within the Myall Lakes National Park. The flow of the river runs adjacent to the coastline and through both the Little Brasswater and the Brasswater near the towns of Tea Gardens, and Hawks Nest.
