The Australian Security Intelligence Organisation raised the national terrorism threat level to “probable” on Aug. 4, 2024 [2].
This escalation signals a significant shift in the national security landscape, indicating that security agencies believe an attack is more likely than not. The move reflects a growing concern over the stability of domestic security amid global geopolitical tensions.
According to Greg Barton, the "probable" designation means there is more than a 50 percent chance of an attack occurring [1]. While the upgrade reflects a heightened risk environment, some reports indicated that no specific, singular threat had been identified at the time of the change [2].
Mike Burgess, the director-general of ASIO, said the agency is gravely concerned about the temperature and trajectory of terrorism threats. He described a "strange cocktail" of risks contributing to the current environment, including the influence of Iran-aligned proxies seeking to spread fear and terror within Australia [1].
Officials said these threats are particularly focused on Jewish communities. Barton said the most common elements of these threats are the justification of violence and the specific targeting of those communities [3].
The shift from "possible" to "probable" follows a period of increasing radicalization and a series of foiled plots. The agency is now monitoring a broader array of actors, ranging from lone actors to state-sponsored proxies, to prevent potential violence on Australian soil [1, 2].
““We are at a threat level of probable, which means there’s more than a 50 per cent chance of an attack.””
The move to a 'probable' threat level indicates that Australian intelligence sees a systemic increase in risk rather than a reaction to a single plot. By highlighting Iran-aligned proxies and the targeting of Jewish communities, ASIO is acknowledging how overseas conflicts are directly impacting domestic security, shifting the threat profile from traditional extremist cells to state-influenced volatility.
