As hosted by naturalist Greg Grainger - one of the world's leading experts on Australian fauna - the hour-long documentary program Wildest Australia visits each major geographic region of the titular continent, for a firsthand exploration of the unique and wondrous species which make up that area's animal populace. The program works in such spectacles as the daily ascents of tree kangaroos, the release of coral polyps on the Great Barrier Reef, the quarrels of a clan of Tasmanian Devils and the behavior of a Kookaburra. ~ Nathan Southern, Rovi
