Senator Thorpe claimed on Tuesday that she did not swear allegiance to the King after protesting during a parliamentary reception for the monarchs on Monday.
"You are not our king. You are not sovereign," she shouted.
"You committed genocide against our people. Give us our land back. Give us what you stole from us - our bones, our skulls, our babies, our people.
"You destroyed our land. Give us a treaty. We want treaty."
Asked on Thursday about the public blowback from her actions, Senator Thorpe said it was "just another day in the colony".
"I wanted to send a message to the King. I got that message across. The whole world is talking about it," she told Nine's Today program.
"My people are happy because my people have been protesting for decades and decades, as you all know, for exactly this.
"So the message has been sent, delivered. Now it's up to the King of England to respond."
The senator for Victoria again rejected coalition calls for her to resign from the upper house.
She then told ABC TV that she swore an oath of allegiance to the late Queen's "hairs" rather than her heirs when taking her seat in 2022.
“I swore allegiance to the Queen’s hairs. If you listen close enough, it wasn’t her heirs, it was her hairs that I was giving my allegiance to,” she said.
“And now that, you know, they’re not no longer here, I don’t know where that stands.”
But on Thursday, Senator Thorpe told Sky News she simply “misspoke” during her swearing-in ceremony.
“I spoke what I read on the card. Now, forgive me for not being – you know, my English grammar isn’t as good as others, and I spoke what I read,” she said.
“So I misspoke, and to have this country question – or particularly people like Dutton and other senators from his party – for them to question my legitimacy in this job is, is an insult. And they can’t get rid of me.”
The federal opposition is examining the senator's eligibility to sit and participate in upper house proceedings under section 42 of the Constitution.
"The coalition will explore options and consider legal opinions as to the implications of Senator Thorpe's admission," the coalition's leader in the Senate, Simon Birmingham, said.
Constitutional lawyer Anne Twoomey told AAP on Thursday that the words the senator had spoken aloud were beside the point because she had also signed a written oath.
The opposition is also considering moving a censure motion against Senator Thorpe when the upper house sits again in November.
The federal government's leader in the Senate, Foreign Minister Penny Wong, said Senator Thorpe's admission about her oath was "an unusual thing".
"I have to say, we're all part of an institution that is the parliament and our democracy, and within that, we have very different views," she told ABC television.
