Australia's domestic spy chief, Mike Burgess, has disclosed that multiple countries, including some considered allies, are engaging in foreign interference within Australia's diaspora communities, with Iran explicitly named. Burgess indicated that at least three or four other nations are involved in activities ranging from surveillance operations to attempts at influencing elections and intimidating Australian residents. The revelation comes as Australia raises its terrorism threat level to 'probable' due to increased politically motivated violence and the proliferation of extreme ideologies. Burgess highlighted the challenges posed by misinformation on social media in addressing these threats. He warned that he might publicly name the nations involved if the security threat persists.
