Because Australian winters are relatively mild in the regions where koalas are found, koalas do exactly the same as they do in summer - climb trees and feed on eucalyptus leaves.
Koalas do smetimes curl up tightly when they sleep. They curl up in winter to keep warm.

its fur keeps it warm
Koalas are mammals, and most mammals have skin, either with or without fur or hair. In the case of the koala, the fur has particular functions. The koala's fur helps to keep it cool in summer and warm in winter. Its outer layer is partially waterproof, so that when rains do come, the koala does not become saturated.
Koalas live in exactly the same place during winter as they do in summer, and that is in eucalyptus trees. Despite the changing seasons, koalas do not need to change where they live, as they are well equipped physically for cold winter nights and hot summer days.
