Tina hails from Sydney and initially wanted to be an anthropologist before studying drama at the National Institute of Dramatic Art, graduating in 1971. Tina began her career in musicals and stand-up comedy, before developing her craft in more serious roles on stage. She became a notable name with the Australian public when she starred in the TV drama "Skyways", set in an airport, playing the cool blonde administrator Louise Carter, and then reinvented her public persona with a role in " Prison er" as the scheming Sonia Stevens. Tina continues to work in all media, consolidating her reputation as one of Australia's best actresses.
