Bobby Marshall is a fictional character from the Australian Channel Seven soap opera Home and Away, played by Nicolle Dickson. She was introduced in the pilot episode by executive producer Alan Bateman. Nearly four hundred actresses auditioned to play Bobby, with Dickson taking the role. Bobby is described as a trouble-making teen who is rebellious and a loner. Bobby became a popular character because of her confronting attitude. Bobby's story lines have focused on finding her biological parents, her feud with Roo Stewart, adoption and her marriage to foster brother Frank Morgan. Bobby's marriage to Frank was only implemented when script writers were sure viewers approved of it. At certain points in Bobby's duration, Dickson disapproved of her actions, for instance she became frustrated with her because she decided to find her biological parents without thinking about her foster parents' feelings. Dickson decided to leave the serial in 1993, and the character was killed off in a boat accident. In 1995 Dickson made a cameo appearance when Ailsa Stewart has hallucinations of Bobby in her fridge door. Dickson has received a Logie Award for her portrayal of Bobby and she has been referred to as a "Summer Bay icon".
