Sam Dastyari, an opposition senator and an Iranian-born Muslim, said: “We have seen the stunt of all stunts in this chamber by Sen. Hanson.”

“The close to 500,000 Muslim Australians do not deserve to be targeted, do not deserve to be marginalized, do not deserve to be ridiculed, do not deserve to have their faith made some political point by the desperate leader of a desperate political party,” Dastyari said.

Senate President Stephen Parry said Hanson’s identity had been confirmed before she entered the chamber. He also said he would not dictate the standards of dress for the chamber.
