Thomas Sewell (born c. 1993) is a New Zealand-born Australian neo-Nazi activist and organiser,[1][2] known for controversial public stunts, violent criminal conduct, and promotion of National Socialism.

[3][15] Videos leaked to the press in November 2019 revealed Sewell's aim was to attract and recruit members from mainstream society using the pretense of a men's fitness club.

[1][20] In January 2021, over the Australia Day weekend, 38 members of EAM were photographed performing Nazi salutes next to Lake Bellfield at the foot of the Grampians in western Victoria.

[30][33] In August 2021, Nick McKenzie hosted a segment on 60 Minutes showcasing their investigation involving an undercover operative infiltrating the NSN.

[34] During part of the undercover footage, Sewell admits that during a previous police raid of his house that they found on his phone a meme celebrating Brenton Tarrant.

[36] Sewell and other members of the NSN marched down Spring Street, performed Nazi salutes on the stairs of Parliament House and referred to transgender people as paedophiles.

[7] Police told Sewell that the reasons for the order were his ideology, his associates, incidents he's been involved in, his criminal history and his goal of intimidating and provoking people.

[40] On 22 October 2024 Sewell and other NSN members attempted to disrupt a refugee rights protest outside of a Department of Home Affairs office.

[41][42] In the alleged comments, Sewell stated that his followers had identified a Victoria police officer who had attempted to remove a mask from one of the neo-Nazis who had attended the counterprotest.

Police alleged that Sewell was wearing a Arrow Cross star which is linked to a Hungarian fascist party with Nazi associations.

During the hearing Sewell stated that was not prepared agree to the bail conditions, which included a ban on associating or communicating with other neo-Nazis in the NSN.

[21] Sewell's stated goal was to encourage the "speed and ferocity of the decay" of society and to help foment a "race war" by exploiting issues raised by politicians.

[49] Sewell was suspended from X in July 2024, but the Croweater page remains, featuring a photo of masked members carrying a banner reading "Australia for the white man".

[49] In an interview in 2019, Sewell was quoted as saying that he would see violence against minorities as an option "if the state continues its persecution of our people for wanting to preserve their culture and heritage".

[5] In a June 2024 podcast, Sewell falsely claimed that authorities in the United Kingdom had threatened to remove children from families because of their parent's political views.

[43] Sewell then said that he would commit acts of terrorism and encourage his followers to do likewise if the courts began ordering children to be removed from neo-Nazi parents.

When asked by ABC News if recommending violence was acceptable, he stated that "terrorising white Australians for their political beliefs" would result in an "irreversible chain of events".

[43] Kristy Campion, who studies Australian far-right extremism, stated that central to the NSN's worldview "is the belief that if they do not act, it will be their children who suffer".

[43] In 2025, Sewell posted a video of Elon Musk straight-arm gestures describing it as a "Donald Trump White Power moment".
