Tristan started work in Australia as a walk on/stuntman and doubled as a boom carrier also doing sound effects in the parking lot at night and volunteering for any other work which would keep him on the lot and in peoples eyesight. He landed a series regular role in 1969 but this folded after about ten episodes so he headed for England and had three years of intense experience where he finally figured out that he REALLY did want to act.
Back in Australia in 1972 Tristan found himself working in all manner of local productions. For the next seven years it was non-stop work in everything form television to radio. By then the idea of coming to America had taken hold so in 1979 it was time to move again. He arrived in summer and felt right at home.
In December of 1980 Tristan landed a job in a show called "General Hospital", and his life changed. The show opened many doors for him with appearances on most of the then prominent '80's and '90's television series.
It was during this period he became involved in the American Cinema Awards Foundation, an organization created to honor achievement in the cinema. As the vice-president and director of shows Tristan helped to raise over $4,000,000 for the Motion Picture Retirement Home and Hospital. The organization also afforded him the rare opportunity to work with, and get to know such legendary stars as: Joseph Cotton, Robert Preston, Bette Davis, Sophie Loren, Robert Mitchum, Glenn Ford, Elizabeth Taylor, Bob Hope and many, many more.
In 1992 he made the momentous decision to leave "General Hospital" and seek other challenges. He had always felt that it is after all show business and that he had only participated in one portion of it and that in order to do the other he had to commit to it. His first experience on the production side came about in 1996 after he had spent several years researching a show about what is arguably his first love, motor racing. In 1997 Tristan found himself in Canada where he was instrumental in launching a show for the Showtime Network called "Fast Track", set in the world of American stock-car racing. The show lasted for 22 episodes and the learning experience was priceless.
In addition to producing Tristan continues to appear in major films, television shows, as well as being the spokes voice for several major TV ad campaigns.
