A man has been charged with allegedly sending a series of offensive emails to a witness who appeared at the Royal Commission on Antisemitism and Social Cohesion.
Investigators with the Australian Federal Police said they received a report about the offensive emails in May.
Three emails were allegedly linked to a 59-year-old man.
On Thursday, a search warrant was executed in Woodburn, on the NSW far north coast, with investigators seizing electronic devices and two prohibited weapons.
Right-wing literature and pamphlets and instructions on making explosives were also seized for further examination.
The man has been charged with four counts of using a carriage service to menace, harass or cause offence, one count of intimidating a witness and two counts of possessing a prohibited weapon.
