Alaa Adam Atwani is accused of supporting the Islamic State in Iraq in 2014 by providing "Sony Vegas video-editing software" to a relative who had travelled to the conflict zone.

Australian Federal Police (AFP) alleged Mr Atwani's relative was working for the "media unit" of the group.

AFP assistant commissioner Ian McCartney said the arrest had helped protect national security.

"We will allege that the support this man provided was tangible and would directly assist a terrorist organisation with its objectives," he said.

According to court documents, police alleged the offence occurred in Sydney between late October and early November in 2014.

Rohith Rajana, who lived above Mr Atwani in a semi-detached house, said the man only moved in a few months ago and kept to himself.

"I had no clue … he was just quiet," he said.

Neighbour Dharam Singh said he was shocked to hear about the arrest.

"[I am] 100 per cent surprised. We used to think it was really peaceful and quiet here, it's shocking to be honest," he said.

Neighbours said they believed Mr Atwani was an engineer who did not spend a lot of time at home.

Assistant commissioner Peter Fleming from the Security and Counter Terrorism Command said the extremist groups used the internet to "exploit" and recruit people.

"The aim of extremists is to divide us and to turn our citizens against each other — but we will not let them win," Assistant Commissioner Fleming said.

Police also offered their assurance that there was no ongoing threat to the Queensland public.

Assistant Commissioner McCartney said the arrest highlighted the strong working relationships between Australia's law enforcement agencies.

"The AFP is committed to working with national security and law enforcement partners to identify all criminality associated with Australians who illegally travelled to participate in the conflict in Syria and Iraq," he said.

Mr Atwani was also revealed as a former Queensland police recruit.

A spokesperson from the the Queensland Police Service (QPS) said it was not at liberty to discuss the nature of each specific case.

"[The] failure to disclose relevant information may result in the termination of a recruit's contract," the QPS spokesperson said.

Mr Atwani appeared briefly in Richlands Magistrates Court this morning.

There was no application for bail and he was remanded in custody.

His case is due for mention in court again next month, when Mr Atwani is expected to appear via video link.
