Police allege the 37-year-old made a series of social media posts featuring nationalist, violent, racist, and extremist messaging.
The counter-terrorism officer allege the man was a regular and consistent social media user where he made violent threats against groups of people online.
In these posts, he would identify groups by race, political viewpoints and occupation, officers said.
It’s also alleged that he advocated for violence against several Australian politicians.
The NSW Joint Counter Terrorism Team started formally investigating the man’s online activity after his social media posts were considered to be criminal offences.
A search warrant was executed at a home in Tamworth and two semi-rural blocks over the past two days.
A number of electronic devices, as well as handwritten and printed material, were seized.
The man was arrested at his home about 4.30pm yesterday and taken to Tamworth Police Station.
He was charged with offences relating to urging violence against people and advocating terrorism.
Both of the offences can carry a maximum prison term of five years.
He will reappear before the court next year.
Authorities believe the man’s alleged posts could inspire others to commit violence in communities.
“This man’s quantity of messages on online forums was of similar concern to the actual content of the messages – resulting in the very real fear that it would inspire someone to commit a violent or terrorist act,” AFP Assistant Commissioner Scott Lee.
“The AFP and its partners will not hesitate to act quickly and lay charges if we identify criminal offences in online activity that promotes violent extremist messages, as our core duty is to ensure the ongoing safety of our entire community.”
