Wyn, found your research while perusing photos on Google Earth and Panoramio around Sorrento and Portsea, Mornington Peninsula, Victoria, where I holiday. My uncle was a top body-surfer, but stopped after an encounter with a Great White at Portsea around 1963/1964 I believe. He was out the back with his close friend (can't remember the name now) and the shark brushed past him, stripping skin off his leg with its bony hide, and took his friend. Pete was so shocked he swam ashore, walked right past the guy's wife on the beach, and drove home to Melbourne, not speaking to anyone for three days. The shark was later caught and the bones of his friend were verified in its belly. The jawbone of the shark was in the Sorrento Aquarium until it closed down a couple of years ago. Uncle Pete never went back in the sea. In fact it was fifteen years before be even went out in a boat again. He just turned 75 last month, and both his brothers still swim in the surf, as I do. I can probably get more details if you want... though it's probably still too painful to ask Pete.
