Thomas Gibson Dysart billed, well known as Tommy Dysart, was a British-born Australian stage, television, and film actor, known for his appearances on television dramas and comedies and in character roles in films and miniseries.
Born on December 24, 1935, in Maryhill, Glasgow, Lanarkshire, Scotland, United Kingdom, Dysart graduated from NIDA in 1959, and started his career as a vocalist and performed in theatre.
In the early 1980s, Dysart appeared briefly in the series Prisoner, where he played what is perhaps his best-known acting role, that of vicious and cold prison officer Jock Stewart.
In the storyline, after being fired from the prison service, Stewart admitted to prisoner Judy Bryant that he was the one responsible for murdering her lesbian lover, fellow prisoner Sharon Gilmour.
This revelation brought to a close murder-mystery storyline in the series but launched a long-running story-arc where Bryant repeatedly escaped from prison in a succession of attempts to exact her revenge on Stewart.
