Snowy Mountains
From Tardis Wiki, the free Doctor Who reference
The Snowy Mountains were located in Australia. Nate Simms once skied there over the course of a number of days. He stayed in a wooden house in the town of Jindabyne. The mountains were part of the boundary between New South Wales and Victoria. (PROSE: Invasion of the Cat-People)
Behind the scenes
Technically, Cat-People calls the mountains the "Snow Mountains", but this is a fairly obvious typo.
