Perisher Ski Resort is the largest ski resort in the Southern Hemisphere. Located in the Australian Snowy Mountains, the resort is an amalgamation of four villages and their associated ski fields, covering approximately 12 square kilometres (5 sq mi), with the base elevation at 1,720 metres (5,640 ft) AHD, and the summit elevation of 2,054 metres (6,739 ft) at the top of Mount Perisher. 4.4 square kilometres (1.7 sq mi) of this area is covered by 240 snow guns, which are used to artificially supplement the natural snowfall. Perisher was acquired by Vail Resorts, United States on 30 March 2015 for a sum of approximately AU$177 million.

A ski resort is a resort developed for skiing, snowboarding, and other winter sports. In Europe, most ski resorts are towns or villages in or adjacent to a ski area – a mountainous area with pistes and a ski lift system. In North America, it is more common for ski areas to exist well away from towns, so ski resorts usually are destination resorts, often purpose-built and self-contained, where skiing is the main activity.
