Waterways play a crucial role in Victoria's geography, agriculture, and recreation.
* **The Murray River:** Forms the majority of the border between Victoria and New South Wales, serving as a vital agricultural lifeline and a hub for houseboating and fishing. * **The Yarra River:** Flows through the Yarra Valley and directly through the heart of Melbourne into Port Phillip Bay. * **Port Phillip Bay and Western Port:** Major coastal embayments that serve as commercial shipping channels and recreational hubs. * **The Gippsland Lakes:** Australia's largest inland network of waterways, featuring lakes, marshes, and lagoons separated from the ocean by the Ninety Mile Beach. * **Inland Lakes:** Man-made reservoirs like Lake Eildon and natural lakes such as Lake Wendouree (Ballarat) are popular for water skiing, rowing, and fishing.
