A major police response was underway in Canberra on Monday afternoon after the ACT court complex was evacuated following a suspected bomb threat.

Police responded to the courthouse at approximately 3:30pm on 14 September, with the incident prompting an emergency operation in the city centre. The court complex was cleared while authorities assessed the reported threat and worked to determine whether there was any genuine danger to people inside or around the building.

The evacuation affected a significant public building in central Canberra and came as court proceedings and other services were operating during the weekday. Emergency responses to suspected explosive threats typically involve securing the surrounding area, moving people away from potential danger and conducting searches before a location can safely return to normal operations.

The incident also involved an Australian Public Service office in the area, according to reporting on the emergency response. The presence of multiple public facilities means police and emergency personnel must carefully assess access points and nearby areas while investigating a threat.

At this stage, the incident has been described as a suspected bomb threat, rather than confirmation that an explosive device was present. Authorities were investigating the circumstances surrounding the threat and determining the appropriate response.

For people travelling through central Canberra, incidents of this nature can result in temporary restrictions, delays and changes to normal access around affected buildings. Members of the public are generally advised to follow police directions and avoid entering areas that have been cordoned off during an emergency response.

The evacuation demonstrates the precautionary approach taken by authorities when a potential explosive threat is reported. Even when a threat ultimately proves unfounded, emergency services must treat reports seriously until the location has been assessed and declared safe.

The ACT court complex is an important part of Canberra's justice system, making any major security incident there particularly significant for court staff, legal professionals, people attending proceedings and members of the public.

Police activity remained focused on assessing the suspected threat and securing the area. Further information is expected as authorities establish what prompted the evacuation and whether any charges or further action will follow.
