Sam was introduced into the serial as a foster child of
Bobby Simpson (
Nicolle Dickson). His father,
Greg Marshall (
Ross Newton) is later introduced into the series and goes onto marry Bobby. However, Bobby dies in a boating accident and Greg abandons him. Sam is subsequently fostered by
Pippa (
Debra Lawrance) and
Michael Ross (Dennis Coard). Sam is washed into a river and Michael dies after attempting to save him. A columnist for
MSN online described the character's tenure stating that "with basically everyone parental in his life either dying or skipping town, Sam was moved between families like a young pass-the-parcel." When Pippa departs the series, Sam is placed in
Rebecca (
Belinda Emmett) and
Travis Nash's (
Nic Testoni) care. The official
Home and Away website stated that Sam's personality changed during this period. He becomes "very prickly and rebellious". Rebecca and Travis cannot cope with a "restless teenager's behaviour" and send him to live with
Donald Fisher (
Norman Coburn). After several years apart, Sam arranges a reunion with Greg. However, Sam is left feeling betrayed and disappointed when Greg fails to show up. Sam returns home to his guardian Donald and he hopes for some comforting words from him, but Donald cannot bring himself to open up. Another love interest for the character was introduced later that year. Herbison's colleague Annette Dasey said Sam would have his "first big romance" with
Daria Ellis (Tamra Williams), the hippy daughter of the new surf shop owner. Clark said it is love at first sight for Sam, explaining "She's meditating in her front yard when he rides past on his paper round. Sam thinks she's absolutely gorgeous." When Sam returns in 2002, he reveals that he has become successful on the professional surfing circuit. ==Storylines==
