There is no "special" climate that koalas need in which to live. It is more that they need a specific biome, one that contains the types of eucalypts trees which provide their food and shelter.
Koalas can be found in a range of climatic zones, as long as they have their food requirements met. They most commonly inhabit warm temperate zones. They are known to inhabit cooler areas of southern Australia, including sub-alpine regions, and extend north up the Queensland coast (sub-tropical, but not rainforests) and inland where the weather is hotter and drier.

No. Koalas cannot live in savanna. They need to be in an area where there are many gum trees (eucalyptus) of the specific type they need to feed. Savanna, or grassland, does not have enough gum trees for koalas.
No, koalas do not live in the deserts of Australia. They need eucalyptus trees for food and they do not grow in the deserts.
No. There are no jungles in Australia, but there are rainforests. Koalas cannot live in rainforests, as rainforest trees do not provide the food koalas need. Koalas need certain species of eucalyptus trees to survive. Much of Australia's non-desert areas are made up of eucalyptus and native bushland. Koalas live in eucalyptus bushland, wherever there are sufficient eucalyptus trees of their preferred variety.
Koalas do not, and cannot, live in the desert. Koalas need access to gum trees. Their habitat is eucalypt woodland and bushland, but of the several hundred species of eucalyptus ("gum trees"), koalas prefer about 60 varieties, with their specific preferences being limited to a couple of dozen.
No, penguins do not need to keep warm because they live in a very cold climate.
There are no "special" koalas. Koalas live on a highly specialised diet consisting primarily of certain types of gum tree leaves (eucalyptus). They do not eat all types of gum tree leaves: of the 300 or so species in Australia, they are restricted to eating the leaves of just 60, and within that 60 there are a dozen or so of their preferred variety. A koala colony will not survive if the animals do not have ready access to any of these dozen species of gums.
Koalas live in closed bushland - primarily eucalyptus forest - along Australia's eastern coast and southeastern coast and inland.Koalas do not live in rainforests, as rainforests do not support the eucalyptus trees they need for food and shelter.
Well it really depends on what zoo you live near.
No. Koalas are found only in bushland along the eastern and southern coasts of Australia. They cannot live in the desert, as deserts do not support enough of the type of eucalyptus tree that koalas need.
No, koalas do not live in the tundra. Koalas require eucalyptus bushland in temperate or sub-tropical zones of eastern Australia. Tundra is too cold. Australia's only tundra is on Mt Kosciuszko and nearby high country, which does not support the eucalyptus trees koalas need for their survival.
There are two main misconceptions in this question. Firstly, koalas are not bears. They are marsupials, whereas bears are placental mammals. The two are completely unrelated. Secondly, koalas do not live in the jungle. There are no jungles in Australia, but there are rainforests. Koalas cannot live in rainforests, either, as rainforest trees do not provide the food koalas need. Koalas live in eucalyptus bushland or low woodland: wherever there are sufficient eucalyptus trees of their preferred variety.
