Central Highlands (Tasmania) in the context of River Derwent (Tasmania)

The River Derwent, also known as timtumili minanya in palawa kani, is a significant river and tidal estuary in Tasmania, Australia. It begins its journey as a freshwater river in the Central Highlands at Lake St Clair, descending over 700 metres (2,300 ft) across a distance of more than 200 kilometres (120 mi). At the settlement of New Norfolk in the Derwent Valley its waters become brackish, flowing through Hobart, the capital city of Tasmania, its seawater estuary eventually empties into Storm Bay and the Tasman Sea.

Historically, the banks of the Derwent were covered by forests and frequented by Aboriginal Tasmanians. With the arrival of European settlers, the area saw agricultural development and the construction of dams for hydro-electricity generation during the 20th century.

The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion in southern New South Wales, Australia, and is the tallest mountain range in mainland Australia, being part of the continent's Great Dividing Range, a cordillera system. It makes up the northeastern half of the Australian Alps (the other half being the Victorian Alps) and contains Australia's five tallest peaks, all of which are above 2,100 m (6,890 ft), including the tallest Mount Kosciuszko, which reaches to a height of 2,228 m (7,310 ft) above sea level. The offshore Tasmanian highlands makes up the only other major alpine region present in the whole of Australia.

The Snowy Mountains experience large natural snowfalls for several months of the year; with significant accumulation during May, June, July, August, September and October with the snow cover usually melting by November (although it can occasionally persist through high summer and the next autumn). It is considered to be one of the centres of the Australian ski industry during the winter months, with all four snow resorts in New South Wales being located in the region. The range is host to the mountain plum-pine, a low-lying type of conifer.
