Australian counter-terrorism authorities are investigating the firebombing of a Melbourne defence manufacturer as a suspected act of politically motivated terrorism, saying the attack appears to have been carried out by alleged far-left extremists motivated by anarchist and revolutionary ideologies.

The Victorian Joint Counter Terrorism Team (JCTT) announced on Wednesday that it had released CCTV images of several suspects believed to be responsible for an attack on Lovitt Technologies Australia in Greensborough, in Melbourne’s north-east, during the early hours of 5 July 2025.

The investigation marks one of the rare occasions in Australia that authorities have publicly described an alleged act of politically motivated violence as potentially linked to far-left extremist ideology rather than religiously motivated or right-wing extremism.

According to investigators, the offenders arrived at the Lovitt Technologies facility at approximately 3.55am wearing dark clothing, masks and gloves before vandalising the premises and setting multiple vehicles on fire.

Police allege the group fled the scene by riding e-bikes along the Plenty River corridor after carrying out the attack.

Authorities believe the company was deliberately targeted because the offenders believed it formed part of Australia’s broader defence manufacturing supply chain, particularly through components ultimately supplied for the F-35 Joint Strike Fighter program.

Days after the attack, investigators allege masked members of the group uploaded a video claiming responsibility.

The recording reportedly featured individuals standing in front of a Palestinian flag alongside Aboriginal and Torres Strait Islander flags while condemning the Australian Government and expressing support for Palestine.

Police further allege the video included instructions demonstrating how to construct an improvised incendiary device similar to those allegedly used during the attack, making the footage a significant focus of the ongoing investigation.

Australian Federal Police Detective Superintendent Anthony Hall said investigators had gathered substantial information about those allegedly involved and indicated arrests could occur at any time.

“We clearly have some information about these alleged offenders and are focused on identifying who they are,” Hall said.

He warned members of the alleged group that police remained determined to identify everyone involved and bring them before the courts.

Hall also stressed that terrorism offences carry some of Australia’s most severe criminal penalties.

“We cannot overstate the seriousness of this criminality and the AFP, together with our partners, will not tolerate acts of terror motivated by extremist ideologies aiming to cause fear and anguish in our community,” he said.

Victoria Police Detective Acting Superintendent Anthony Wheatfill similarly described the alleged conduct as placing the broader community at risk.

He said using fire and explosive devices to promote political or ideological causes was unacceptable because of the potential to cause catastrophic consequences beyond the intended target.

“Fire is dangerous and unpredictable and criminal offending of this nature – which has the potential to significantly impact our community and lead to deaths or serious injury – will not be tolerated,” Wheatfill said.

The Victorian Joint Counter Terrorism Team is a multi-agency taskforce comprising Victoria Police, the Australian Federal Police and the Australian Security Intelligence Organisation (ASIO). It investigates suspected terrorism offences and other nationally significant security matters.

Authorities said the suspects could face multiple terrorism-related charges if sufficient evidence is obtained, with some offences carrying maximum penalties of life imprisonment.

Police have appealed for members of the public to assist the investigation by providing dashcam footage or any other information relating to activity around the Greensborough industrial area during the early hours of 5 July 2025.

CCTV images released by investigators show several individuals dressed entirely in black with backpacks and face coverings, although police have not publicly identified any suspects by name.

Lovitt Technologies manufactures precision-engineered components for the aerospace and defence industries and supplies products to major international defence contractors, including companies involved in the F-35 Joint Strike Fighter program.

While the company exports components through global defence supply chains, Australian authorities have previously stated that local manufacturers do not directly supply weapons systems to Israel. Nevertheless, investigators allege the attackers believed the business was connected to military equipment ultimately used by the Israeli Defence Forces.

The investigation comes against the backdrop of heightened tensions surrounding the Israel–Hamas conflict, which has prompted numerous protests across Australia since late 2023.

Although the overwhelming majority of demonstrations have been peaceful, security agencies have increasingly warned about the risk that a small number of individuals may seek to justify criminal violence through political or ideological causes.

ASIO has previously identified ideologically motivated violent extremism as one of Australia’s principal national security concerns, noting that threats can emerge from a range of ideological backgrounds rather than a single movement.

The alleged attack has also renewed discussion about the legal threshold for terrorism offences in Australia.

Under Commonwealth law, an act may be prosecuted as terrorism if it is carried out with the intention of advancing a political, religious or ideological cause while seeking to intimidate governments or the public through serious violence, threats or major property damage.

Whether those legal thresholds have been met will ultimately be determined through the courts if charges are laid.

Investigators have not announced any arrests, and no individual has been charged over the alleged firebombing at the time of publication.

Authorities say Operation Braehead remains active and have urged anyone with information about the identities or movements of the offenders to contact Crime Stoppers or the Australian Federal Police.

The investigation represents one of the most significant counter-terrorism inquiries currently underway in Victoria and highlights growing concern among security agencies that politically motivated violence—regardless of ideology—poses an ongoing threat to public safety.
