Australia, previously a part of the supercontinent Gondwana, became isolated and evolved its own distinct flora due to its extended separation. Owing to its vast expanse, the country boasts diverse trees adapted to various climatic zones, ranging from tropical to subalpine landscapes.
In the tropical regions, Australia showcases an array of vegetation including palms and is home to the world's oldest surviving rainforest, the Daintree.
Adjacent to the tropics along the eastern coastline, the Gondwana Rainforest stands as the largest expanse of subtropical rainforest globally.
Heading south to the temperate zone, you will find various temperate rainforests on and near the slopes of the Great Dividing Range, Cape Otway, and the island state of Tasmania.
The largest climatic zone in Australia is arid and semi arid where vast deserts occupy the centre of the continent. Here Australian trees and plants still exist, but are sparsely populated. Instead of cactus which is not native to Australia, Acacia forests and shrubs dot the barren landscape. Eucalypts are also common, but are much more numerous in wetter areas further south.
