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."
Senator Hanson, who is calling for a ban on full face-coverings in public places on grounds of social cohesion and public safety, said it was "a security risk" and should not be allowed into the Senate.
She said it underscored her point that she had not been visually identified by security before entering the chamber, though Senate President Stephen Parry said on Thursday she had been identified by another senator.
Senator Hanson-Young shot back: "Everyone knew it was you being a goose. Everyone knew it was you putting the country in danger and having a stupid stunt."
ASIO head Duncan Lewis said on Friday during a press conference - without commenting directly on Senator Hanson's stunt - that "our relationship with the Islamic and Muslim community here in Australia is absolutely critical ??? central to our business".
Senator Hanson made a number of incorrect claims about other countries banning the burqa.
"Why have we got Islamic countries around the world that are actually banning the burqa? Tunisia, Turkey, Congo. These are Islamic countries - Malaysia - they've banned the burqa for national security."
The Republic of Congo in west Africa banned the burqa in public places in 2015 but is not a majority Muslim country with just 1.6 per cent of the country practising the religion, according to the CIA Factbook.
Turkey has in the past had restrictions on strict Islamic dress in government buildings though these have been eased. Tunisia lifted a ban on head scarves in 2011 but has had a continuing debate on whether face coverings should be permitted.
Senator Hanson said, nonetheless, the issue needed to be discussed.
"People are out on the streets. It's OK for us. We're secure in the Parliament, we've got security guards, we've got federal police with guns. What about the people out there?
"If I've got to drive it to wake these people up, these politicians, to get, you know, heads out of the bloody sand and see what's going on ??? "
