Antisemitism has affected Jews since Australia's Jewish community was established in the 18th century, becoming more pronounced in the late 19th century, rising further in the 20th and early 21st centuries. There are a number of organisations that track antisemitic activities, including the Executive Council of Australian Jewry, that publish an annual list of all reported antisemitic activities. According to the Anti-Defamation League's 2014 Global100 survey, an estimated 14% of Australians harbour antisemitic views. In 2025, this percentage rose to 20%. Antisemitism in Australia is perpetrated by a variety of groups, and it has manifested in attacks on Australian Jews and their religious and communal institutions, in antisemitic publications, and in efforts to prevent Jewish immigration.
