Australia–Iran relations

Australia–Iran relations (Persian: روابط استرالیا و ایران) refers to bilateral relations between the Commonwealth of Australia and the Islamic Republic of Iran. Australia had maintained, despite a strenuous relationship, a continuous diplomatic presence in Iran from 1968 to 2025. Iran, in kind, has had an embassy in Canberra from 1971 to 2025.

In August 2025, the relationship severely deteriorated after the Australian prime minister announced that the Australian Security Intelligence Organisation had concluded that Iran had ordered several clandestine terrorist attacks inside Australia during 2024. Australia expelled the Iranian ambassador and other Iranian consular staff, declaring them persona non grata. Australia also ceased operations at the Australian embassy in Tehran, and declared the Islamic Revolutionary Guard Corps a terrorist organisation.

Australia, like most Western countries, has expressed concerns about Iran's human-rights record and its nuclear-weapons program, and has issued sanctions against Iran for abuse and violations of human rights as well as for supplying drones to assist Russia in its war against Ukraine.

According to the 2004 census, 18,798 people in Australia have Iranian ancestry. It is estimated that 25,000 people of Iranian descent live in Australia, most of whom came after the 1979 Iranian Revolution.

Australia officially listed Islamic Revolutionary Guard Corps (IRGC) as a "state sponsor of terrorism" after its security services concluded the IRGC orchestrated antisemitic arson attacks in Sydney and Melbourne.
