Cornelia Rau is a German and Australian citizen who was unlawfully detained for a period of ten months in 2004 and 2005 as part of the Australian Government's mandatory detention program. Her detention became the subject of a government inquiry which was later expanded to investigate over 200 other cases of suspected unlawful detention by the Australian government's Department of Immigration and Multicultural and Indigenous Affairs (DIMIA). Rau was the inspiration for the character Sofie Werner portrayed by Yvonne Strahovski in the 2020 show Stateless.
