Enid Lyons was elected the first female member of the Australian House of Representatives, winning the seat of Darwin. After the end of World War II, the state saw major urbanisation, and the growth of towns like Ulverstone. It gained a reputation as "Sanitorium of the South" and a health-focused tourist boom began to grow. The MS Princess of Tasmania began her maiden voyage in 1959, the first car ferry to Tasmania. As part of the boom, Tasmania allowed the opening of the first casino in Australia in 1968 Queen Elizabeth II visited the state in 1954, and the 50s and 60s were charactered by the opening of major public services, including the Tasmanian Housing Department and Metro Tasmania public bus services. A jail was opened at Risdon in 1960, and the State Library of Tasmania the same year. The University of Tasmania also moved to its present location in 1963.
