In 1983, Tasmania gained worldwide recognition through a controversy thought by many to be the awakening of Australia's conservation conscience. Blockades by environmentalists on the remote southwest region and protests in other major cities saved the area from being doomed, and it's now on the World Heritage listing.

Glenn Ridge visits Tasmania to witness the area first-hand, and stops off at locations such as the Gordon and Franklin rivers, the infamous Sarah Island Penal colony, the endangered King River and the historic township of Strahan.

Using spectacular aerial vision, Tasmania's Wilderness Frontier gives a great insight into the beauty of this once controversial region, and may justify why conservationists fought so hard to preserve it in its natural form.
