The Great Dividing Range is the biggest mountain range, and starts in central Victoria and ends in Northern Queensland, some several thousand kilometres in length, making it the fourth longest range in the world. An area on the Victoria and New South Wales border receives more snow than the country of Switzerland.
Other prominent mountain ranges include The Hammersley Ranges, the Flinders Ranges, the Macdonell Ranges, the Darling Ranges, and the King Leopold Ranges.
Northern Australia is located in the tropics and the landscape consists of rainforest which leads into large areas of savanna grasslands which eventually merge into the central deserts. These deserts are the largest in the world outside of the Sahara. This part of Australia's is called the Red Centre, because of the unusual red colour in the sand.
Tasmania to the south is a mountainous island about the same size as Ireland or Sri Lanka located in the temperate climatic zone immediately below the Australian continent. One quarter of this island is protected wilderness and is similar in appearance to nearby New Zealand.
The Southwest corner of Australia is populated by Karri Forests which rate as some of the tallest trees on Earth.
