The next terrorist attack will "be on your head, Pauline", Greens senator Sarah Hanson-Young has told Pauline Hanson after the One Nation's burqa stunt on the floor of the Senate.

In an early-morning clash on television, Senator Hanson-Young told her political polar-opposite that Senator Hanson's wearing a burqa in Parliament last week contradicted the advice of security agencies who say the Muslim community is a vital ally in the fight against terrorism and marginalising it is unhelpful.

"You're doing ISIS's work for them. It is extremely dangerous. You're putting the entire country at risk," Senator Hanson-Young said on Channel Seven's Sunrise program.

She ended the fiery exchange by saying: "The next attack in Australia will be on your head, Pauline."
