Werribee Plain

The Werribee Plain is an expansive low-lying flat land located between the northwestern shore of Port Phillip Bay and the Grampians Central Highlands of Victoria, Australia, shared between Melbourne and Geelong. Named after the Werribee River, the plains are notable for their extensive, flat and rather featureless spans, interspersed by the occasional vertical feature, such as the You Yangs, a series of granite ridges and several small extinct volcanoes.

The Werribee Plain forms the eastern bayside portion of the vast Western Volcanic Plains between the Grampians and the Otway Ranges, which extend from the western suburbs of Melbourne to the South Australian border.^[1]
