She also downplayed the response Senator Brandis received to his rebuke, pointing out that no Coalition members took part in a standing ovation.
"I couldn't believe his reaction to this. He's talks about having a go at a religious organisation - you know, the Muslims, that type of thing. Wearing the burqa is not a religious requirement."
She claimed to not know about any feedback from the Muslim community, but said she has received a lot of support from Australians.
"I actually got a message from a woman in Saudi Arabia who actually has congratulated me and said 'thank you because we want to get rid of the scarf that we have to wear'," she said.
During a press conference in Canberra, Prime Minister Malcolm Turnbull took aim at Senator Hanson's stunt.
"The (Muslim community) are our best allies in every respect and that is why the foundation of the success of ours, the greatest, most successful multicultural society in the world, is mutual respect," Mr Turnbull said.
"Mutual respect is critical. Mutual respect is not just the foundation of our success as a multicultural society, it's the foundation of our national security, because that enables us to live together, work together, in harmony."
It was almost important for national security and intelligence-gathering to maintain "good relation with the Muslim community", the prime minister said.
"Look, it was a stunt. And I'm not going to dignify stunts in the Senate with much more commentary other than to say that George spoke with great eloquance and wisdom."
Cabinet Minister Christopher Pyne said he's wasn't sure what the point of Senator Hanson's stunt was, given her later statements about security in Parliament House.
"Once Pauline Hanson is inside the entrances of Parliament House and been through security, quite frankly, what she wears in Question Time has no bearing on security whatsoever," he told Nine Network.
Mr Pyne reminded Senator Hanson she was meant to be a leader in the community.
"She's a leader in Australia, and to ensure that our country is cohesive we actually need to work with all the communities in it to protect each other from terrorists."
Labor frontbencher Anthony Albanese said Senator Hanson's stunt had no place in the Australian parliament.
"I think that George Brandis' response was correct, courageous and spot on," he said.
