Australia’s ecosystems range from rich rainforests to the savannahs and teeming deserts of the interior.

More than 80 per cent of this continent’s flowering plant, mammal, reptile, and frog species are found nowhere else in the world. Many species are in decline – Australia is the site of half of all the world’s mammal extinctions in the past 200 years. Earthwatch is working to help protect and restore Australia’s extraordinary environment and natural heritage. Join our projects in this unique land for an extraordinary experience and to help us fulfill our mission.
