Dom Moran - Brad Armstrong

Bradley "Brad" Armstrong, played by Chris Sadrinna, made his first appearance on 11 July 2006 and departed on 13 November 2007. Shortly before he arrived, an Inside Soap reporter stated that Brad would help ease Sally Fletcher's (Kate Ritchie) pain over the death of her husband, Flynn Saunders (Joel McIlroy). A spokesperson from the show revealed "Sally's due a bit of good luck. Brad's a nice guy, but he has his fair share of problems – which develop when his mother is killed in tragic circumstances. But he and Sally will draw strength from each other."

Brad arrives in Summer Bay following the death of his mother Elaine (Julie Hudspeth). Sally Fletcher arrives to find Brad in Leah Patterson-Baker's (Ada Nicodemou) house naked. Brad tries to help his sister Rachel (Amy Mathews) with her grief and organises Elaine's funeral. When Brad is locked out, Sally finds him naked again. Brad later saves her from a burning building. Emily Vincent (Libby Richmond), Brad's girlfriend arrives and they get married on the beach in a small ceremony but she dies of leukaemia, leaving him devastated. Brad and Sally grow closer, as she had lost her husband Flynn Saunders several months earlier. When Rocco Cooper (Ian Meadows) enrols at Summer Bay High, Brad is reluctant to give him a chance but Sally is willing. Rocco's brother, Johnny (Callan Mulvey) arrives and angers Brad. At Christmas. Brad and Sally share a kiss under the mistletoe and plan to have dinner together, but Sally does not arrive but is found bleeding outside of the school after being stabbed by Rocco on Johnny's orders. Sally recovers and she and Brad's bond strengthens when he moves in with her.

Naomi Preston (Tiffany Preece) arrives and Brad discovers her relationship with Lucas Holden (Rhys Wakefield). Naomi twists the story to make it look like Brad had knowledge of the relationship before she began teaching at the school. Brad is later stood down as principal but things look up when Sally accepts his marriage proposal. On the day of the wedding, Sally jilts Brad, leaving him hurt and and he moves out. While on a boat trip with Alf Stewart (Ray Meagher), Ric Dalby (Mark Furze), Dan Baker (Tim Campbell) and Jack Holden (Paul O'Brien), a storm occurs and the men are lost at sea but return safely. Brad and Rachel later learn their father Robert (John Gregg) had an affair with Heather McCabe (Olivia Pigeot), resulting in a daughter, Tamsyn (Gabrielle Scollay), their half-sister. Heather leaves Tam with Rachel and Brad to attend a gambling rehab programme. They struggle to look after to Tam, as she defies Rachel's authority. Brad takes sole care of Tam but due to her behaviour he loses out on a job at Yabbie Creek High. He supports Sally when her daughter Pippa is hit by Alf's Ute. Heather returns and Brad decides to move to Tasmania and invites her and Tam to come with him and they accept.
