(CNN) -- The 32-year-old Texas man who died in a shark attack over the weekend while scuba diving off Western Australia was remembered Sunday by his sisters as "unique" and "one of a kind." Sharon Wainwright of Panama City, Florida, identified the victim as her son, George Thomas Wainwright. His sisters, Brenda Wainwright and Wanda Brannon, spoke to CNN affiliate WMBB-TV. "It's devastating. It's hard to even wrap your head around. I can't believe he's gone. I think it was just wrong place, wrong time because he was very wise. I would trust him with anything to do with being on the water," said Brenda Wainwright.NEW: "I think it was just wrong place, wrong time," the victim's sister saysGeorge Thomas Wainwright died while scuba divingHis mother says his body is expected in Florida in about four daysAuthorities believe the man was killed by a great white off the Australian coast
