Roslyn studied music during her childhood but started her professional life working as a primary school teacher in Sydney. Deciding to become an actress, Roslyn trained at the National Institute for Dramatic Art. She is probably best remembered as one of the most outrageous characters ever to appear in the cult TV drama “Prisoner”, playing Laura Gardiner, a shy librarian by day but a tough-talking prostitute, working under the name Brandy Carter, by night.
