After high school, Augustin first did a commercial apprenticeship in Erlangen. He then completed an apprenticeship at the Film and Television University in Munich. He played on stages in Munich, Detmold and numerous touring theaters. In 1966 he made his film acting debut in a short film directed by Marran Gosov, under which he starred several more times. Augustin appeared in numerous light comedies such as Engelchen or Die Jungfrau von Bamberg (with Gila von Weitershausen) and Helgalein (alongside Anita Kupsch), often playing stiff and awkward characters. He became known to a wide audience in 1973 as a comedian in the comedy series Klimbim. In the first season of Michael Pfleghar's entertainment series, Augustin acted in various skits and disguises and as the father of the "Klimbim family". After a year Augustin left the production. In the years that followed, he played in Alfred Vohrer's adaptation of Erich Kästner's Three Men in the Snow, in Werner Herzog's Woyzeck adaptation (with Klaus Kinski in the title role), in the Gottschalk comedy Tender Chaos and made guest appearances in numerous television series such as Der Kommissar, Police Inspection 1, The Fast Gerdi and Claude Chabrol's Histoires Insolites.
