Two notorious Australian Neo-Nazis have been exposed as the likely architects of a menacing video in which a masked man denigrates Indigenous senator Lidia Thorpe before burning the Aboriginal flag.

A forensic analysis by ABC Investigations suggests reasonable grounds to suspect Melbourne men Jimeone Roberts and Stefanos Eracleous are behind the footage which sparked national outrage last week.

In a Melbourne press conference on Thursday, Senator Thorpe — who has been campaigning for a No vote in the Voice to parliament referendum — accused the AFP of failing to protect her from racist abuse and threats, saying: "For four months I wasn't allowed to be in my home because people want to kill me out there".

Archives of private Telegram chats provided by antifascist research group White Rose Society showed Eracleous had signed a letter with the alias "John Dixon" during a dispute with a Melbourne publican last year.

Independent far-right and extremist researcher Kaz Ross reviewed the analysis by ABC Investigations and said: "I have zero doubts in my mind that it was Jim [Roberts] and Stefanos [Eracleous's] video".

A Melbourne magistrate last year labelled his actions "disgusting, vile and repugnant" after he put up more than 50 swastika stickers in a suburb with a large Jewish population, the day after the Victorian government announced it would criminalise the hate symbol.
