Imagine the scene, 23 million years ago, as the Mt Warning Volcano erupted, rising 2 kilometres into the lava and volcanic ash over an area of 100 kilometres. 20 million years of erosion has not only produced the biggest caldera in the southern hemisphere, a designated ‘Landscape Of National Significance’ (Australian Tourism) – bigger in size than the famous Ngorongoro Crater in Tanzania, but also ‘Australia’s Green Cauldron’, supporting some of the richest sub-tropical wildlife in the world. Join host Lin Sutherland in this stunning documentary, filmed over the changing seasons, as she introduces the fauna and flora that inhabit this wonderfully unique Australian environment.
