Gippsland occupies much of the south-eastern part of Victoria. It lies to the east of the eastern suburbs of Greater Melbourne, to the north of Bass Strait, to the west of the Tasman Sea, to the south of the Black-Allan Line that marks part of the Victorian/New South Wales border, and to the east and southeast of the Great Dividing Range that lies within the Hume region and the Victorian Alps.
The region is best known for its primary production such as mining, power generation and farming as well as its tourist destinations— Phillip Island, Wilsons Promontory, the Gippsland Lakes, Walhalla, the Baw Baw Plateau, and the Strzelecki Ranges.
The Gippsland Lakes are a network of lakes, marshes and lagoons in east Gippsland, Victoria, Australia covering an area of about 354 square kilometres (137 sq mi). The largest of the lakes are Lake Wellington, Lake King and Lake Victoria. The lakes are collectively fed by the Avon, Thomson, Latrobe, Mitchell, Nicholson and Tambo rivers.
The numbers of Southern Right Whales and Humpback Whales using the Lake Entrance area have shown increases in recent years as the populations have recovered. The lakes are home to about 50 of the recently described species of Bottlenose dolphin, the Burrunan dolphin (Tursiops australis). The other 150 or so of this rare species are to be found in Port Phillip. The wetlands provide habitat for about 20,000 waterbirds – including birds from as far afield as Siberia and Alaska.
