Police will allege the Flinders Park man posted videos to social media that encouraged people in overseas conflict zones to commit terrorist acts.
Police said he was arrested on Thursday “at a facility in Northfield” after information was passed to the South Australian Joint Counter Terrorism Team through the National Security Hotline and will appear in the Adelaide Magistrates Court at a later date.
He was believed to already be in custody at the time of his arrest but further details have not be released.
However, police have moved to allay public fears over the allegations.
“There are no current or impending threats to the Australian community as a result of these activities,” they said in a statement.
