The fallout from a secret undercover scheme exposing Australia's Nazi movement

It's another humiliating blow for the National Socialist Network after being infiltrated by an operative who was able to secretly film their activities.

Our infiltration last week of the country's largest far-right extremist organisation exposed a degree of evil that was difficult to comprehend; disgusting racism and calls for violent unrest.

The important work of the undercover operative in unmasking the neo-Nazis had an immediate effect.

Several of them have lost their jobs, and counter terror police have launched numerous fresh investigations.

And while the rotten ship of white supremacy hasn't quite sunk yet, plenty of its rats are deserting.

Now, senior members of the Coalition and Labor are calling for the NSN to be banned as a terror group.

But while the power battle within the NSN plays out, 60 Minutes, The Age and The Sydney Morning Herald have set out to find the links between other Australian Nazis and overseas groups.

We're zeroing in on Australia's west coast to try and unmask the key recruiter for a dangerous group in the United States.

Australia's top spy, Mike Burgess, doesn't shy away from the danger posed by neo-Nazis infiltrating our military.

In his first television interview, The ASIO boss told 60 Minutes a growing number of Australian men are being drawn to neo-Nazi extremist groups overseas.

"It's the online community that allows them to connect with other like-minded people, where they can encourage acts of violence, or be encouraged for acts of violence," he said.

Up until three months ago, Tom Sewell was the undisputed leader of the NSN and believed the Proud Boys movement could help his own neo-Nazi empire grow.

So, in early May this year while our undercover operative was investigating, Sewell set out a plan to bring Jaz Searby, the Australian leader of The Proud Boys, to Racism HQ to train his men.

But what Tom Sewell didn't anticipate was that two weeks later he'd be arrested by counter terror police and charged with armed robbery. He was refused bail, and his matter remains before the courts.

Mike Burgess told reporter Nick McKenzie the threat posed by these groups shouldn't be underestimated.

"They're smart, tech savvy and there's no doubt they have an understanding of the laws of our land," he said.
