A tourist mauled in a horror shark attack has been pictured for the first time as her hero partner fights for life in hospital. Livia Muhlheim and her boyfriend, 26-year-old Lukas Schindler, were swimming at first light in waters off Kylies Beach at Crowdy Bay, Australia , on Thursday. The Swiss couple were approached by a three-metre bull shark, which struck instantly. Mr Schindler, a qualified diving instructor, fought desperately to save his girlfriend as the predator sunk its teeth into her.
