Australian Federal Police (AFP) arrested 58-year-old Gavin Begbie at his Woodburn, New South Wales home on Thursday following an investigation into the harassment of a witness appearing before the Royal Commission on Antisemitism and Social Cohesion. Mr. Begbie faces charges related to the intimidation of a witness and the possession of prohibited weapons, as well as neo-Nazi materials including leaflets for the proscribed National Socialist Network.
Investigation and Arrest Details
The AFP’s National Security Investigations team launched an inquiry in May after receiving a report regarding three emails sent to a witness involved in the royal commission. Following a search warrant executed at the Woodburn property, police seized a knife, a whip, and a copy of Adolf Hitler’s Mein Kampf. According to the AFP, officers also discovered instructions on manufacturing explosives, which are currently undergoing further examination.

Mr. Begbie has been charged with four counts of using a carriage service to menace, harass, or cause offence. Additionally, he faces two counts of possessing a prohibited weapon and one count of intimidating a witness.
The National Socialist Network (NSN) was officially proscribed as a hate group in May. This legislative action followed the December terror attack at a Hanukkah event in Bondi Beach, which resulted in the deaths of 15 people.
Context of the Royal Commission
The Royal Commission on Antisemitism and Social Cohesion is currently investigating the circumstances surrounding the Bondi Beach shooting. The inquiry is also examining the broader climate of antisemitism in Australia that preceded the attack. Many of the witnesses providing testimony to the commission are Jewish Australians.
The arrest follows a public warning issued in May by Royal Commissioner Virginia Bell, who stated that the commission was monitoring instances of intimidation and recording offensive social media posts directed at witnesses. AFP Assistant Commissioner Peter Crozier noted that the force possesses the resources to identify and prosecute those attempting to interfere with judicial processes.
The charges against Mr. Begbie highlight the heightened security environment surrounding the commission. By linking the seizure of neo-Nazi materials to the intimidation of a witness, authorities are signaling that threats against inquiry participants will be treated as serious security matters rather than isolated incidents of harassment. The inclusion of explosive-making instructions suggests that investigators are looking beyond the emails to assess potential broader risks to public safety.
What May Happen Next
As the legal process moves forward, the evidence seized—including the explosive-making instructions and the neo-Nazi literature—will likely undergo forensic analysis to determine if further charges are warranted. The commission is expected to continue its oversight of witness safety, and the AFP has signaled that it will maintain its focus on identifying those who seek to threaten individuals involved in the judicial system.
