Australia expelled the Iranian ambassador in Canberra as well as three other embassy staffers on Tuesday, with Prime Minister Anthony Albanese accusing the Islamic Revolutionary Guard Corps of orchestrating attacks on a synagogue in Melbourne and a kosher restaurant in Sydney.

Albanese, speaking at a press conference alongside the country’s top intelligence official, foreign minister and home affairs minister, called the plots “extraordinary and dangerous acts of aggression orchestrated by a foreign nation on Australian soil.” The expulsion of Ahmad Sadeghi marks the first time Australia has expelled a foreign ambassador since World War II.

Canberra also withdrew its diplomatic staff from Iran and has encouraged Australian citizens to leave the country if they are able.

Australian intelligence indicates that Tehran was behind additional antisemitic attacks in the country since the Oct. 7, 2023, Hamas terror attacks. The country has seen an explosion of antisemitism, with a 316% year-over-year increase in antisemitic incidents in the year following the attacks.

Mike Burgess, the director-general of the Australian Security Intelligence Organisation, said that the plots were carried out “through a series of overseas cut-out facilitators to coordinators that found their way to tasking Australians,” describing the scheme as a “layer cake” of middlemen originating with the IRGC.

The expulsion of the Iranian diplomats comes shortly after the arrests of two individuals in connection with the December 2024 Melbourne synagogue attack, in which a synagogue was firebombed while nearly two dozen people were inside. 

The arson at Sydney’s Lewis’ Continental Kitchen, which took place in October 2024, caused $1 million in damage to the kosher restaurant. Court documents released earlier this month indicate that a middleman, Sayed Moosawi, who was directing the Sydney attack, was to receive $12,000 for his work. Prior to the fire at Lewis’ Continental Kitchen, two men directed by Moosawi mistakenly set fire to a brewery with a similar name to the restaurant.
