A Perth man has been charged after he allegedly posed as a woman online to chat about sexually abusing young children.

An investigation into the man began in July 2019 when the WA Joint Anti Child Exploitation Team received a report from the United States’ National Centre for Missing and Exploited Children about a person uploading child abuse material to social media.

Police will allege over a two year period, the 22-year-old pretended to be a woman on social media to engage in explicit conversations with men where “she” discussed the sexual abuse of a teenage girl and young children.

The man was arrested by the AFP last year.

A search warrant was executed at the man’s Palmyra home on December 17 last year, and Australian Federal Police seized a mobile phone.
