New spate of stabbings, overdoses and fires at Australian immigration detention centres run by ICE-linked US prison firm

Melbourne immigration detention centre saw violence, aggression, illicit substances and improvised weapons. These incidents matter because they created risks for detainees and workers, and Comcare said the government was likely breaching workplace safety law by failing to control them.

On 18 August, two groups fought at Melbourne. Six detainees went to hospital with slashing and stabbing injuries caused by improvised weapons. On 10 September, staff found another detainee overdosed in his room and administered Naloxone, which reverses opioid overdose effects.

Villawood immigration detention centre faced a different but related danger. Eight fire-related incidents occurred between February and May. The incidents followed earlier warnings about fire safety, including a 2025 fire in which two workers were hospitalised after entering a detainee’s room without proper safety equipment.

Immigration detention centres are facilities where people are held under Australia’s immigration system while the government manages their immigration status. They are not ordinary prisons in the article’s description, but they require security, health care, staffing and emergency controls. Their safety matters because workers and detainees share the risks created inside the facilities.

The Australian government sets the system’s responsibilities and contracts companies to run operations. Management and Training Corporation, or MTC, won a $2.3bn detention contract in late 2024. Its local subsidiary, Secure Journeys, operates the centres and is expected to maintain safe and secure operations, staff welfare and detainee welfare.

Private operation does not remove government oversight. The Department of Home Affairs has used financial penalties and ministerial pressure to improve performance. Comcare has also directed attention toward the department, saying it must ensure risks are controlled so far as reasonably practicable.

The reported problems are serious because they involve repeated hazards across more than one centre. Melbourne experienced violence, aggression, illicit substances and improvised weapons. Villawood experienced eight fire-related incidents between February and May. Comcare said the hazards posed an ongoing risk of serious harm to workers and others.

The Melbourne violence produced a stark measure of harm. On 18 August, an altercation between two groups left six detainees hospitalised with slashing and stabbing injuries. On 10 September, staff treated a detainee who had overdosed with Naloxone. Villawood’s fires followed earlier concerns about inadequate preparedness.

The problems also sit within a major contracted system. MTC won the $2.3bn detention contract in late 2024. The article also describes escapes, staff injuries and missed medical appointments elsewhere in the network, suggesting the reported failures are broader than the incidents at these two centres.

Poor controls can expose workers and detainees to serious harm. Violence and improvised weapons can cause severe injuries. Illicit substances can lead to overdoses. Fires can trap people or injure staff during emergency responses. Comcare said these hazards created an ongoing risk of serious harm inside the centres.

The article gives concrete examples. Six detainees were hospitalised after slashing and stabbing injuries at Melbourne. Another detainee overdosed and needed Naloxone. At Villawood, two workers were hospitalised after entering a burning detainee room without proper safety equipment during an earlier fire. These events show how risks can harm both groups.

There are legal and operational consequences as well. Comcare said the department was likely contravening section 19 of the WHS Act. It could require stronger controls or further regulatory intervention. Continuing failures may also deepen pressure on Secure Journeys, MTC and the government to improve staffing, security and emergency preparedness.

The government can be held responsible because it controls the department that manages the detention network and influences how risks are handled. Under the workplace safety law cited by Comcare, the department must ensure, so far as reasonably practicable, the health and safety of workers and other people. Contracting out operations does not end that duty.

Secure Journeys performs operational work, but Comcare focused on the department’s failure to demonstrate effective controls. The regulator said violence, aggression, illicit substances and improvised weapons were not adequately managed. It also found the department had not systematically reviewed all fire and smoke controls within its influence or control.

This creates shared accountability. MTC and Secure Journeys must operate safely, while the government must oversee, assess and respond to risks. The department has used penalties and ministerial pressure, but Comcare’s notices show that oversight must produce effective controls, not merely promises or actions that cannot be demonstrated.

The latest Comcare notices did not arise without warning. Earlier fires at Villawood had already exposed serious gaps in MTC’s preparedness. The regulator had previously warned the government to intervene. Despite that history, further fire-related incidents occurred over roughly four months.

On 23 September 2025, MTC staff entered a detainee’s room to rescue him from a fire without proper safety equipment. Two workers were hospitalised. Comcare later said the department had not conducted its own systematic review of all fire and smoke controls within its influence or control.

Other background warnings came from repeated failures across the network after Secure Journeys took over. The Guardian had reported escapes, staff injuries and sick detainees missing medical appointments because escorts were unavailable. The union also repeatedly raised understaffing concerns. Comcare said the later incidents provided repeated and compelling reasons to review whether controls were effective.

The article identifies a core requirement in section 19 of the WHS Act: the department must ensure, so far as reasonably practicable, the health and safety of workers and other persons. This means foreseeable hazards must be identified and controlled, rather than ignored after someone is injured. The duty covers risks inside the detention network.

Comcare applied that principle to violence, aggression, illicit substances, improvised weapons and fires. It said the department had not sufficiently demonstrated that existing controls were effective in eliminating or minimising those risks. For fires, the regulator said the department had not systematically reviewed fire and smoke controls within its influence or control.

The practical implication is continuous oversight. When repeated incidents show that controls may not work, responsible agencies must review and improve them. Comcare said multiple fires after earlier regulatory intervention created compelling circumstances for such a review. The notices indicate that action must be effective, not merely claimed.
