The south-east coast drainage division is the very long, narrow area of southern Australia between the Great Dividing Range and the Coral and Tasman seas, Bass Strait and the . It includes the small part of south-eastern South Australia which lies to the east of the Murray-Darling Basin, and all of coastal Victoria and coastal New South Wales. While the southern, eastern, and western boundaries are clearly defined by geography, the northern boundary is arbitrarily defined as the New South Wales - Queensland border. The distinguishing feature of the drainage basin is the Great Dividing Range and the associated Australian Alps.
Major rivers of the division, from north to south, then east to west include the Clarence, Macleay, Hunter, Hawkesbury-Nepean, Shoalhaven, Clyde, Snowy, La Trobe, Hopkins, and Glenelg rivers.
