Counter-terrorism expert and Labor MP Anne Aly has called for a substantial change in the way far-right extremists are targeted by authorities after the devastating Christchurch mosque massacre.
An Australian man, Brenton Tarrant from Grafton in NSW, has been charged with murder over the mass shooting that claimed the lives of 50 people.
The 28-year-old posted a 74-page "manifesto" online before the attack, and a 17-minute live streamed video was uploaded of him arming himself and entering the mosque where he started shooting.
Dr Aly said while more could be done to target threats online, she was aware companies were acting to stamp out extremist activity.
"What we don't want is a situation where we're playing a game of whack-a-mole where we take down one and 10 more show up in its place," she told ABC radio on Monday.
"What we want is some kind of substantial change."
"It's one thing to have the powers, it's another thing to direct them towards white supremacist movements and to recognise the seriousness of that threat."
Muslim Greens senator Mehreen Faruqi also called for more focus on far-right terror.
"I think there are serious questions to be asked about how much attention agencies and governments have been paying to right-wing extremists," she told ABC Radio National.
"Whenever we raised those issues we've been told we have a victim mentality or we're being too politically correct. I think now is the time to actually listen and act."
She said Home Affairs Minister Peter Dutton and other Liberal politicians had created an atmosphere which incubated hate in society.
"What they've been doing does come with a cost, it does come with consequences because really they've been playing games with our lives," Senator Faruqi said.
Prime Minister Scott Morrison has taken aim at social media companies for not doing enough to ensure Friday's live streamed attack, which was originally uploaded to Facebook, was not republished.
Former crossbench senator David Leyonhjelm, who is running for a seat in the NSW upper house, believes authorities should be using increased powers to stop terrorism.
"The responsibility is on them to use those powers to make sure that they identify the individuals who are in danger of doing these sorts of atrocities," he told the ABC.
ASIO Director-General Duncan Lewis and Australian Federal Police Commissioner Andrew Colvin are expected to address a special meeting of federal cabinet's national security committee on Monday.
