Terry Harrison was an officer at Wentworth Detention Centre appearing from Episode 199 - 223.
Terry is an old friend of Jim Fletcher's who is transferred to Wentworth and becomes romantically involved with Vera Bennett. He is also the ex-husband of prisoner Kathy Hall who arrives at Wentworth in episode 213 along with Dinah Walford. When she receives harmful threats and is bashed, he confronts Kathy about who would have attacked her.
He finds out about Dinah who was already out on parole in episode 215 to which the harsh threats on Kathy have ironically stopped. In episode 216, Harrison confronts Walford after looking for her on the street who denies knowing anything about the attack, who denies it at first. After visiting her male friend, a pimp, he is later beaten up by more of his friends. As it later turns out, Dinah was responsible for the threats and the attack on Kathy to keep her silent about illegal business going on in a pawn shop she went to one night and witnessed involving Dinah and her friends.
Going to the pawn shop to look for answers for Kathy, he threatens the manager who calls in a guy named Harry Bailey who arrives at Vera's apartment with a gun after she comes home and attacks her, looking for Terry. Terry arrives only to be caught in the matter, saved in time by Jim Fletcher who arrives and knocks Bailey unconscious from behind. Involving himself in trouble, this puts an effect on him and Vera's planned marriage to which Vera throws him out of her apartment.
He later creates a set up to have Kathy killed on the day of her release from Wentworth as revenge for their troubled relationship, to which she is immediately in a hit-and-run right outside the building in episode 220. In episode 223, Dinah and some of her gangster friends kidnap Terry to have him work for them or else they'll harm Vera. While trying to work out his relationship with Vera, he informs her on Kathy's death which leads to her telling Inspector Grace who knew Harrison was behind it all along.
To her surprise, Grace decides not to do anything as he has other plans for Harrison. He is seen talking to Grace outside the prison by one of Dinah's friends who look at the conversation the wrong way.
Terry is killed in a hit-an-run as he is shot from behind by a road just outside of Wentworth while trying to reconcile with Vera once more.
