Australia’s terror threat level has been raised from “possible” to “probable”. Here’s what it means.
WHAT HAS CHANGED WITH THE TERROR THREAT?
The Australian government uses a five-step colour-coded scale to warn the public of terrorism threats: from not expected (green), to possible (blue), to probable (yellow), and then expected (orange), and then certain (red).
In a press conference in Canberra on Monday, August 5, Prime Minister Anthony Albanese and ASIO director general Mike Burgess announced the threat level was moving from “possible” to “probable”.
This means authorities believe there is a greater than 50 per cent chance of an attack or planning within the next 12 months.
Along with other western nations, Australia adopted a colour-coded terror threat advisory system in the mid-2000s.
The set level is reviewed when deemed necessary rather than on a cyclic basis.
WHY WAS THE TERROR THREAT CHANGED?
In today’s announcement, Mr Burgess said the decision reflects a “degrading” security environment, which was becoming “more volatile and more unpredictable”.
Social cohesion was “deteriorating,” he said.
The decision comes after eight terror plots were investigated in the past four months.
No recent terror plots in Australia have been directly connected to the current situation in the Middle East, but that conflict could escalate local tensions.
ASIO said it has observed “the emergence of domestic actors increasingly driven to action by sociopolitical issues, intersecting with personal grievances”.
“There is an increase in extremism, fuelled by conspiracy theories and anti-authority ideologies. Some actors hold a blend of ideologies, including those that justify acts of violence to influence change.”
Social media was acting as both a “gateway” for “violent ideologies” and “a key driver of volatility,” ASIO said.
James Morrow, national affairs editor at The Daily Telegraph, said the war in Gaza “is widely considered a key driver to the increased alert levels”.
The rise in anti-Semitic incidents, demonstrations, and the blockades of government offices including the Prime Minister’s own electorate office, would also have factored into ASIO’s decision making, Mr Morrow said.
HAS AUSTRALIA BEEN ON ‘PROBABLY’ TERROR LEVEL BEFORE?
Indeed it has. Security agencies raised Australia’s threat level to “Probable” from “Possible” in 2014, and the rating stayed that way until November 2022.
Today’s announcement moves us back to the position we were in before November 2022.
At the time the then Minister for Home Affairs, Clare O’Neil, said: “The lowering of the threat level does not mean the threat from terrorism is extinguished.”
WHAT HAPPENS NEXT?
While the threat level has been raised, don’t expect to see your civil liberties curtailed overnight or armed guards on city streets.
First and foremost, said ANU terrorism expert Dr Michael Zekulin, the raising of the terror alert is a signal to the Australian public “to be a little more vigilant about what they’re seeing, and what they’re hearing” and report any incidents to the authorities.
Monday’s announcement will also put other agencies tasked with public safety on notice to be more vigilant about terror threats, which could lead to reviews of protocols for major events, Dr Zekulin said.
The Australia government’s online information about the terror threat level states that any local attacks are likely to be by a lone wolf or a small group, using low-cost tactics and readily-available weapons including knives, vehicles, explosives, and firearms.
While concerns about online radicalisation and exposure to extreme content are increasing, Dr Zekulin said it was unclear what pressure the government could exert on the tech giants to ensure content was being moderated.
Facebook declined to comment; responses were being sought from Google, X and TikTok.
If the authorities obtain information about a specific threat, the terror level warning could be raised to expected (orange) or even certain (red) – levels that Australia has never been at before.
DO AUSTRALIANS NEED TO WORRY?
While ASIO has stated the most likely location for a terrorist attack are crowded public events, or places such as shopping centres, transport hubs and places of worship, Dr Zekulin stressed that such terrorism incidents in Australia were still “very, very rare”.
“It’s not a question of changing the way you live your life, or anything like that,” he said.
James Morrow concurred.
“Australians should not be generally more alarmed about the threat of being a victim of a terror attack in their day to day lives,” he said.
“However the heightening of the alert level will have law enforcement agencies and security agencies working overtime, behind the scenes.”
Suspicious activity can be reported to the National Security Hotline on 1800 123 400, via email on hotline@nationalsecurity.gov.au or via SMS on 0429 771 822.
