Gaby Willis is a fictional character from the Australian television soap opera Neighbours, played by Rachel Blakely. The show's casting director spotted Blakely on the cover of a magazine and asked her to audition for the role of Gaby. Blakely received the part and she was introduced to the show during a period of roller-coaster ratings. She made her first appearance during the episode broadcast on 12 August 1991. Gaby was introduced as the eldest daughter of Doug (Terence Donovan) and Pam Willis (Sue Jones). She comes to Erinsborough, after taking a business course in Japan. Gaby is characterised as beautiful, intelligent and the apple of her father's eye. She also has a temper, leading Blakely to call her fiery. Gaby opens her own fashion boutique, with the help and support from her boyfriend, and later fiancé, Glen Donnelly (Richard Huggett). Gaby and Glen's engagement ends when he flees Erinsborough following an accident. Gaby's business burns down and she becomes a punk to cope with her losses. She also befriends and briefly dates a punk musician. Gaby takes a job as a barmaid, before becoming a secretary at the Robinson Corporation. Gaby becomes attracted to teacher Wayne Duncan (Jonathon Sammy-Lee), with whom she shares a real chemistry. However, the couple are mismatched and they often fight. Gaby and Wayne realise their relationship is destructive and they end it. Blakely believed the breakup with Wayne was Gaby's fault and called for her character to grow up. Gaby takes flying lessons and she falls for her instructor, Jack Flynn (Mark Pennell). Gaby becomes pregnant and Jack refuses to stand by her. Gaby later gives birth to a son, who is named Zac (Jay Callahan). Blakely's decision to quit Neighbours in 1993, led to Gaby taking a less stressful job in Darwin after struggling to balance her career and motherhood. Her departure aired on 2 September 1994. Blakely later reprised the role to appear in the show's 20th anniversary episode, which was broadcast on 27 July 2005.
