Video footage from the raids obtained by The Herald shows his wife and the children being led away from the home by uniformed police, while officers swarm on the Auburn home.
Senior sources say that the man remains under surveillance because of his suspected radical views and links to Islamic State, but he has not been charged with any offence under Australian law.
He is believed to not have actually participated in the fighting in Syria, but spent time there with the radical group before returning and allegedly continuing his work for the Caliphate.
«An administrator is the right term for him,» a source familiar with the investigation into the man said.
The man remains involved with the Islamic State’s encrypted online messaging, sources say, and continues to take care of the WhatsApp and Telegram groups that the radical Islamic group uses to communicate internally and for recruiting.
The man came back from his stint in the self-declared Islamic State different, people who knew him say.
«When he came back, he was angrier,» said his former neighbour.
«He was more radical. He made his wife wear the niqab [a face-covering veil associated with conservative elements of Islam], and he was very controlling of his children.»
Documents leaked by online vigilante group Ghost Squad Hack showed that several of the accused Islamic State supporter’s children are enrolled in local Islamic school Al Bayan. He is understood to attend South Granville mosque Al Noor, where some sources suggest he became radicalised.
The former security guard, who has no criminal convictions, has also spent time living in a town in NSW’s Central West.
Images purported to be from his phone depict the Islamic State flag flying above Venice, explosions, blood stained knives, children brandishing Islamic State flags, a meme saying «One bullet away from Paradise» and critically wounded soldiers.
Alleged Islamic State members from other countries including Indonesia, Belgium and Uganda were also exposed in the global data dump.
Leaked data showed one Belgian teenager, known to be an Islamic State supporter, had a video on his phone about how to most effectively behead someone.
The teenager, who cannot be named, was one of the almost 30 Belgian nationals exposed in the Ghost Squad Hackers.
