The pics below are from Joe Goding from his recent trip to Tassie. They include some DWS at Blackmans Bay, and some shots taken from a boat cruise out to Cape Pillar. Cripes there is a lot of rock out there!

As far as I know there are a few routes on "The Blade" at Cape Pillar done by Bob McMahon, Gerry Narkowicz, Ben Maddison et al. There was an article in Rock a while back. But AFAIK there are no routes at Black Head. There is a world of potential out there for somebody with a boat.
