The One Nation Leader was in full black when she walked into the chamber, to the outrage of Labor Senators.
Her identity was checked before she entered the red chamber.
Senator Hanson, who exclusively spoke to The Courier-Mail before she entered the Senate, will give a significant speech at 4pm to call for the face covering to be banned in Parliament and across the country.
Senators continued on with Question Time in the Upper House as normal while Senator Hanson sat in the full black covering.
Labor senators called “shame” and “you’re a disgrace” as Senator Hanson rose to ask if the Government would work towards implementing the ban.
Senator Derryn Hinch questioned why she was allowed in “fancy dress’’.
The Speaker Stephen Parry said he would not dictate what people could wear.
Attorney-General George Brandis received a standing ovation from the Labor senators when he called Hanson’s stunt “appalling”.
“Senator Hanson, no, we will not be banning the burqa,” Brandis said.
“I am not going to pretend to ignore the stunt that you have tried to pull today by arriving in the Chamber dressed in a burqa when we all know that you are not an adherent of the Islamic faith.
“I would caution and counsel you with respect to be very, very careful of the offence you may do to the religious sensibilities of other Australians.”
