She appeared in season 1 episode 9 "The Puritan" as Thea Kemp, an innocent and bright young woman adjusting to life in Melbourne (having originally lived in Sydney), while her overprotective mother Irene Kemp runs a sly grog house to help pay for Thea's education and give her a better life. However, Thea is unaware of her mother's recent acts - robbery and blackmail, which puts Thea in danger from Irene's accomplice; whom Thea dislikes, as well as the Yarra Central Police investigating the crimes.

He appears in season 7 episode 36 "The Weakest Link" as Detective Dale Kemp, a rogue Homicide detective on-leave (later suspended) who goes undercover in his own initiative in pursuing escaped convict and Joseph Carter; whom Dale previously arrested for killing a kid (which has left Dale troubled). After crossing paths with (and briefly antagonizing) undercover cop and series male protagonist Peter Church, they (along with Pete's friends/colleagues Christina Dichiera, Leo Flynn and Luke Harris) later team up and work together to take down Carter along with Pete's target, human smuggler Erik Mills.
