Australis is the great southern continent of Pandora. It contains a number of lush jungles and rainforests, as well as vertigo-inducing mountains. The edge of Australis juts into the Equatorial Sea; it is here that the RDA and the Avatar team are stationed. Australis is also the home of the Na'vi Omaticaya clan.
