After studying a business course in Japan, Gaby returns to Erinsborough to be with her family. She learns her parents are on the verge of bankruptcy and she poses as a lawyer to get Wilf Turner (Terry Trimble), one of her father's debtors to pay an outstanding debt. 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.
