The first episode – retitled "The General" – aired in Sydney on 8 August 1971, and the rest of Australia on 26 August 1971. It was originally intended to produce 26 episodes, but following the success of the first series, Mirams held talks with both Nine Network and Paramount Pictures, who backed him for a second series. In all 42 episodes were produced. The series was last aired on Australian television in Adelaide on 21 September 1976, but has been re-run several times since.
