Australia is a megadiverse country, with 7–10% of the world’s species. It’s home to 84% of plant species, mammals, and 45% of birds. The country and its surrounding seas support 600,000–700,000 native species, with a very high proportion found nowhere else. Australia’s biodiversity has developed over millions of years, largely in isolation.
