On 2 September 2022, as Minister for Multicultural Affairs, Bettison said that there would be a Parliamentary inquiry into "neo-Nazi symbols, the activities of extremist groups, discrimination faced by targeted groups and the prohibition on symbols in other states". This was partly prompted by the activities of a group of neo-Nazis who had posted photographs of themselves giving fascist salutes outside the Adelaide Holocaust Museum, and concerns had been raised about the activities of groups such as the National Socialist Network in South Australia.[7]
