A Sydney woman has been charged by the Australian Federal Police (AFP) after allegedly using social media accounts to promote violent extremism and possessing dozens of related files on her mobile phone.

The 23-year-old woman, from Quakers Hill, was identified following a tip-off to the AFP in July 2025 that a Sydney-based person was actively sharing extremist material and glorifying martyrdom online.

The investigation quickly focused on the young woman, leading to a search warrant executed at her home that same month. Police seized a mobile phone for forensic analysis, which allegedly uncovered 43 files classified as violent extremist material.

Police will allege that this material encouraged serious acts of violence and was intended to inspire others to commit similar crimes. 

It is also alleged that the woman operated two social media accounts which were used to upload and share this dangerous content with the wider community, celebrating allegiance to known terrorist groups.

The AFP formally charged the woman with two offences relating to using a telecommunications service to possess and share violent extremist material. Both charges carry a maximum penalty of five years in prison.
