Australia's Ecology

Australia’s terrestrial protected area system covers 19% of its terrain. Far more impressive is its marine protected area system, which covers 40% of Australia’s marine habitat, including the largest coral reef in the world, the Great Barrier Reef. Indigenous Peoples continue to exert powerful protected area leadership, advocating for new protections and serving in guardian capacities for current parks and monuments.
