The range also contains the five highest peaks on the Australian mainland (including Mount Kosciuszko), all of which are above 2100 m .  They are located in southern New South Wales and are part of the larger Australian Alps and Great Dividing Range.  Unusual for Australia, the mountain range experiences large natural snowfalls every winter.  Snow normally falls the most during June, July and early August.  Therefore, most of the snow usually melts by late spring.  The Tasmanian highlands makes up the other (major) alpine region present in Australia.
