A mysterious Tasmanian tiger photo by a German tourist is looking more like a hoax than proof the famous marsupial is alive. News of the photo emerged late last month when the man's brother in Victoria claimed to have a copy of the picture. The colour photo was said to have been taken in remote wilderness near Lake St Clair. But little has emerged to prove the photograph is genuine since it was first reported. Leading Tasmanian wildlife biologist Nick Mooney said the process was ongoing. "We are still trying to get information, but it is a little like pulling teeth," he said. Mr Mooney was one of a small group of experts called to the Tasmanian Museum and Art Gallery last month to view the photo from the Victorian man, brother of the German photographer. "I haven't seen the photos again, and don't know where they might be," Mr Mooney said. "I have been spending my time trying to encourage them to get some type of forensic examination of the photo. Then we can take it further. "I'm not part of any negotiations, it really is a waiting game. "But there would be many advantages if they did get it verified."
