Senator Hanson told the ABC on Wednesday that she did not believe there are no "good" Muslims and referenced a non-practising Muslim woman who stood for One Nation.
She apologised if she "offended anyone out there that doesn't believe in sharia law, or multiple marriages, or wants to bring ISIS brides in, or people from Gaza that believe in a caliphate".
But she added: "In general, that is what they want — a world caliphate. And I am not going to apologise … I will have my say now before it's too late."
Senator Hanson then suggested that the government's policies were being unduly influenced by Muslim voters and called for a "far more stringent" vetting process for prospective migrants.
"People are in fear. We don't know who these people are. You've got 18,000 people on ASIO's watchlist. Doesn't that tell you something?" she said.
"We've had terrorist attacks in this country, and it's not just about terrorist attacks, it's about our changing way of life."
Senator Hanson alleged that Australians were not welcome in some suburbs with large Muslim populations, such as Lakemba in Sydney's west.
That's not an apology. It's not even a "partial apology", she straight up doubled down on her original comments.
