High Quality Content by WIKIPEDIA articles! The Snowy River is a major river in south-eastern Australia. It originates on the slopes of Mount Kosciuszko, Australia`s highest mainland peak, draining the eastern slopes of the Snowy Mountains in New South Wales, before flowing through the Snowy River National Park in Victoria and emptying into Bass Strait. Up until the mid–20th century, the river was notable for its high volume of fresh water, wide reach and large rapids.
