SYDNEY (AFP) - Australia's military was hit by a fresh scandal on Sunday, with a female sailor claiming she was sexually assaulted by a crewmate on board a mine-hunting ship. The 21-year-old Able Seaman alleged that a fellow sailor, 24, had confronted and then sexually assaulted her aboard HMAS Diamantina while it was docked in Sydney last month, defence officials said. "Military authorities were made aware of the complaint on Friday Sept 9, when the complainant reported the alleged incident to HMAS Diamantinas Naval Police Coxswain, who immediately informed his chain of command," a spokeswoman told AFP.
