85% of Australian indigenous plants that total 28000 species are unique to this land.

Nowadays Australia's tropical north is largely covered with forests, including now almost extinct rainforest. Due to the harsh and dry climate of the inland, plants like eucalypts and wattles (acacias) dominate the grasslands. But despite this climate even the desert turns into a beautiful botanical garden after rainfall.

The gum tree, or eucalypt, is ubiquitous except in the deepest rainforests and the most arid regions. Of the 700 species of the Eucalyptus genus, 95% occur naturally in Australia, the rest grow in New Guinea, the Philippines and Indonesia. Eucalyptus wood is prized and its oil is used for pharmaceutical and cosmetic products.
