Her maternal grandfather was Charles Thomas McGlew, a prominent merchant and founder of the Liberty Motor Oil Company. Her father, Raphael "Ray" Cilento, was a medical practitioner who became famous for his work combating malaria and other tropical diseases. Diane's mother, Phyllis Cilento, was a medical practitioner and medical journalist who advocated for family planning, contraception, and the legalization of abortion in Australia.
Diane was the fifth of six children born to her famous parents, and four of her siblings followed their parents' footsteps as medical practitioners. Her most famous sibling was the professional painter and print-maker Margaret Cilento.
Diane was expelled from school while living in Australia and later studied abroad, spending part of her school years in New York. She decided to follow an acting career and won a scholarship to the Royal Academy of Dramatic Art (RADA) in London. She settled in England during the early 1950s.
After graduating from RADA, Diane started a career as a theatrical actress and was eventually offered a five-year contract by British film producer Alexander Korda. She began her film career with small roles before landing her first leading role in the romantic drama "Passage Home" (1955).
