Australia is stereotypically known for its dry desert landscape and climate, although this is not relatively true as Australia has diverse ranges of climate and temperature zones that can vary from tropical, arid, and snow. As Australia has a large land mass the climate varies, the states closer to the equator, such as Queensland and Northern Territory and the north of western Australia experience with temperatures ranging from 20-24 degrees (in winter) and above 31degrees in summer, this is because these areas are closer to the equator.
Other areas of Australia, more southern parts experience a fewer high temperatures and have a more temperate temperature, areas such as NSW, Victoria, South Australia and parts of Western Australia, with an average temperature of 10-25 degrees (winter) and 30-40 degrees (summer), these are because these cities are further away from the equator and do not have full exposure to the suns light and heat. Although further away, these cities are not cold enough to have snow, very little snow is found in Australia, but towns like Thredbo and Perisher (higher altitude towns on the Great Dividing Range) experience snow during winter.
