Gaby begins taking flying lessons and she gets her pilots license, but not before she falls for her instructor, Jack Flynn (Mark Pennell). After a short romance, Gaby leaves for a job in Europe, but she returns two months later and her family cannot understand why. Gaby then reveals she is pregnant and has decided to keep the baby. An "Inside Soap" columnist said "When she lets slip that the father is no-good flying instructor Jack Flynn, Doug goes berserk and hunts down the man that did his daughter wrong." Jack refuses to take responsibility and Gaby realises she will be a single mother. Though she has the support of her family. Shortly after Gaby announces her pregnancy, Cheryl Stark (Caroline Gillmer) also announces she is pregnant. Monroe said everyone expects Gaby to give birth first, but "in true "Neighbours" style" both Gaby and Cheryl go into labour at the same time. Gaby gives birth to a baby boy who is named Zac (Jay Callahan), while Cheryl gives birth to a daughter. Gaby finds it difficult to balance her career and motherhood and she later takes a less stressful job running a branch of Lassiter's in Darwin.
