Gaby begins making dresses for her friends and neighbours and she decides to open her own boutique in the Lassiter's Complex, with Caroline Alessi (Gillian Blakeney) as her silent partner. The business is successful and profits increase after Glen Donnelly discovers one of Gaby's customers is called Elizabeth Taylor and tells the "Erinsborough News". Gaby considers dating Guy Carpenter until she learns he is seeing Caroline. Gaby then turns to Glen and they fall in love. After a brief split, Glen proposes and Gaby accepts. Glen falls from the roof of Lassiter's Hotel and he is paralysed from the waist down. Gaby stands by him, but Glen later flees Erinsborough, leaving Gaby behind. Gaby's aunt, Faye Hudson (Lorraine Bayly) accidentally causes the boutique to burn down and Gaby finds employment at The Waterhole. Gaby goes through a rebellious phase to cope with her losses and she befriends punk musician, Zed. Gaby competes with her brother, Brad, for the manager's position at the pub, but after confronting their boss, Philip Martin, she is fired. Gaby becomes a secretary at the Robinson Corporation and she is later promoted to manager. Gaby meets Lassiter's client, Simon Hunter, and they begin dating. However, during a weekend away Simon tries to rape Gaby. Gaby presses charges and her father, Doug, hits Simon. Simon blackmails Gaby into dropping the charges, so her father does not get a conviction for assault. Wayne Duncan moves into Ramsay Street and Gaby immediately clashes with him. Her grandfather, Bert (Bud Tingwell), realises she is attracted to Wayne and he tries to get the couple together. Gaby and Wayne admit their feelings for each other and they begin a relationship. Gaby becomes jealous of Wayne's friendship with Annalise Hartman (Kimberly Davies) and when she fails to stand by him after he is accused of murdering biker Cactus (Les Toth), Wayne ends the relationship. After The Waterhole explodes due to a gas leak, Gaby and Philip have to work together to rebuild it. Lassiter's owner, Paul Robinson (Stefan Dennis), tires of their bickering and sends senior associate Jack Parker (Philip Parslow) to Erinsborough to sort them out and choose which one is most suitable for the manager job. Gaby works hard to impress Jack, but when she steals one of Philip's clients, Jack tells Paul that Philip should be given the managerial position.
