A young Sydney man accused of preparing possible terrorist attacks in the name of Islamic State has been remanded in custody ahead of a possible bail application.

Riverwood man Youssef Uweinat, 21, did not appear on Thursday when his case was briefly mentioned at Parramatta Local Court.

His lawyer, Kiki Kyriacou, asked for a bail hearing to be set later in December before acknowledging he would need to file paperwork.

Uweinat was arrested on Wednesday by counter-terrorism police and accused of preparing possible terrorist acts, advocating terrorism and being a member of a terrorist organisation.

Police say the man had, over six months, posted increasingly extremist material online and sought to convince others - particularly teenagers aged 17 and 18 - to pledge allegiance to IS.

The accused also allegedly downloaded a document on how to use knives and other blunt instruments in a terrorist attack.

Authorities say the 21-year-old was connected to others previously charged with terrorism offences in Australia.

Uweinat's next scheduled court date is 13 February.
