An education assistant is accused of harassing children online and paying them to have sex while he filmed them.
Thomas Gottaas, 18, was arrested in the Sydney town of Picton on Tuesday.
The arrest comes after police launched an investigation between September and November that included the seizure of his electronic assets.
The young man is charged with prostitution, production of child abuse material and possession of child abuse material.
He used several fake profiles through which he contacted his victims.
He remains in custody, without the option of posting bail, until his next hearing on March 19.
