“We need to take this seriously. We need to deal with it now.”
His comments have been backed by counter-terrorism experts calling for increased vigilance to tackle the extremist threat.
Mr Husic, who is Australia’s first Muslim member of Parliament, cited an incident last week in which a “man with a machete” walked up to the Holland Park Mosque in Brisbane, terrifying four worshippers in the building.
The same mosque was the target of a graffiti attack last month when swastikas and a reference to the suspect behind the Christchurch terror attacks vandalised the building.
“This isn't right, and it is raising a point and reinforcing a point that I've been raising with the government,” the Labor MP said.
“This stuff is rearing its head in the US, and we've seen it a number of times this year where people have been the victim of some terrible behaviour that has resulted in the loss of life.”
The Christchurch terrorist attack in which 51 people were killed in a shooting that was live-streamed by the Australian suspect, has put the focus back on right-wing extremism this year.
In 2011, Norwegian political terrorist Anders Breivik killed 77 people in 2011 and American Dylan Roof shot dead nine people in an African American church in South Carolina in 2015.
Australian National University counter-terrorism analyst Clive Williams told SBS News right-wing extremism has increasingly shown itself around the world.
“It is probably a link on from what is happening in Europe and in the United States where right-wing related attacks have been more common,” he said.
“I think to some extent right-wing extremists have been ignored because of the great threat since the 1990s from Islamist extremists.”
Professor Williams, who formerly worked as director of intelligence at an Australian intelligence agency, said police and intelligence officials had long warned of the threat.
But he said combatting the scourge can be difficult for counter-terrorism agencies, even when monitoring activities such as hate speech on social media for signs of threatening behaviour.
“The problem is the individuals may not be identifiable until quite late in the piece … I mean it might be a tip-off from the national security hotline like a family member,” he said.
“The most dangerous people are the lone actor who tends to listen and look and not actually do very much, which means of course they’re harder to identify."
Counter-terrorism analyst Greg Barton has also previously called on Australia to do more to counter the threat posed by right-wing extremism.
In his speech, Mr Husic backing the concerns raised by the experts.
“The point is this: I don't care if it's Islamist-inspired or supremacist-inspired, if it represents a threat to the Australian people it should be taken seriously,” he said.
“And I'm telling you now, based on the briefings I've received, we are not taking this seriously. We reckon that we're only following a few people on this issue here in this country.”
Professor Williams said balancing counter-terrorism resources is a challenge for security agencies, saying the general public must also increase their vigilance to guard against the problem.
“There are an awful lot of public resources out there and there are fairly limited national security resources,” he said.
“So it’s beholden on people more generally to keep their eyes open and if they have a concern talk about it.”
It’s a concern Mr Husic recognised in his speech, expressing respect for Australia’s security and intelligence agencies' work to curb the problem.
“We ... know in this day and age, with the rise of the lone wolf, we can’t track these people easily.”
“[But] this form of extremism is very serious, and ... it is crossing borders.”
