One Nation leader Pauline Hanson shocked her fellow senators after entering the chamber during Question Time on Thursday afternoon wearing a full length burqa.
There were audible groans in the Senate as she walked in and one person was heard saying "What on earth?"
Senator Hanson removed the burqa a few minutes later as she attempted to ask the Attorney-General a question on banning the garment altogether.
Senator Brandis' passionate impromptu response to the One Nation senator's stunt earned a standing ovation from Labor and Greens senators.
“You are not an adherent of the Islamic faith,” Senator Brandis said in a passionate response.
“I would caution you and counsel you. Be very, very careful of the offence you may give.”
"We have about 500,000 Australians in this country of the Islamic faith. And the vast majority of them are law abiding good Australians."
Mr Brandis said that it was vital to work with the Muslim community to combat the threat of radicalisation.
"It is vital for their intelligence and law enforcement work that they work cooperatively with the Muslim community, and to ridicule that community, to drive it into a corner, to mock its religious garments is an appalling thing to do and I would ask you to reflect on what you have done."
Independent Derryn Hinch asked Senator Parry whether he could come into the chamber wearing fancy dress, given Senator Hanson is not a Muslim.
“It may have been something that I did that was radical, yes it was, coming into this chamber with a burqa on but it was a case in point saying that I do not believe that at any point in time ever in the future that any full face coverings should ever be worn in this place,” Senator Hanson later said in the chamber.
She has since moved a motion in parliament calling on the federal government to ban the burqa but it was defeated within an hour.
“The fact is wearing a burqa is not a religious requirement. Non Islamic countries like Switzerland, Norway, Germany, France, Belgium, the Netherlands, Spain, China and Russia have also banned full face coverings. Again, lawmakers believe a ban improves public safety and enables social cohesion.
“How can you justify the banning of a helmet or balaclavas but not a burqa when entering a bank?”
She has also renewed her push for a temporary ban on Muslim immigration for at least five years.
“If we do not draw a line in the sand against immigration from Islamic countries, the influence of Muslims in this country will continue to grow and Australia will continue down the path of Islamisation."
Labor Senator Doug Cameron spoke straight after to oppose the motion and condemn Ms Hanson’s earlier stunt.
“A contribution underpinned by racism, a contribution underpinned by religious intolerance and a contribution from my point of view underpinned by just plain stupidity,” Senator Cameron said.
Senator Nick Xenophon has applauded the Attorney General's response to Pauline Hanson's burqa stunt and says it was offensive and demeaning to people of the Islamic faith.
"I know a thing or two about stunts but I wouldn't even call this a stunt, this was just toxic," Senator Xenophon told reporters in Canberra.
Opposition leader Bill Shorten described it as a 'political circus stunt'.
"I do not believe, no matter what anyone thinks, that pulling those sorts of antics in parliament does anything other than trivialise parliament and democracy," Mr Shorten told reporters in Canberra.
NSW Muslim MP Jihad Dib said the incident was "calculated and divisive".
"I did warn you that proroguing the parliament was in national interest. Things are getting seriously weirder by the day," he posted to Twitter.
