Documents provided under freedom of information laws show the total cost of Operation Bourglinster, the AFP investigation into a boy known as Thomas Carrick, was $507,087

Victorian children’s court found that police encouraged Thomas in his fixation on Islamic State during an undercover operation after his parents sought help from the authorities.

17 April 2021, his parents went to a police station and asked for help because Thomas was watching Islamic State-related videos on his computer and had asked his mother to buy bomb-making ingredients such as sulphur and acetone.

Thomas, an NDIS recipient with an IQ of 71, was first reported to police by Victoria’s Department of Health and Human Services (DHHS) and then by his parents because of his fixation with Islamic State, which included him accessing extremist material online and making threats to other students.

Thomas was investigated and charged with two terror offences by the Joint Counter Terrorism Team (JCTT), which comprises Australian federal police, Victoria police and Asio members. He was the youngest person ever charged with those offences
