Independent Senator, Indigenous Treaty and sovereignty advocate and DjabWurrung Gunnai Gunditjmara woman Lidia Thorpe says she is receiving formal protection as a result of recent threats to her safety.
Senator Thorpe cut ties with Greens in February citing the party's support for the Voice to Parliament without stating her official stance on the proposal as she moved to the crossbench.
She later announced her opposition to the Voice and has since fronted the Blak Sovereign Movement promoting Treaty ahead of an advisory body to government.
In an interview with The Project's Hamish Macdonald aired on Wednesday, Senator Thorpe said the Voice "has nothing to do with giving our peoples the power that they need to make real change that is needed".
"We want power in this country. We want land back. We want peace. We want the end of the war that was declared on us. We don't want to continue to talk about high rates of deaths of our people, incarceration of our people. We're still locking up 10 year olds in this country," she said.
Senator Thorpe alleged aggressive public response to her passionate, and often controversial political actions has prompted a serious safeguard.
"There are a lot of people out there who... don't want me in parliament, who don't want me alive... I've felt very unsafe the last few weeks and until things are resolved then I continue to feel unsafe and it's shit. It's really horrible not feeling safe in your everyday life just because of the things you do in your job that are genuinely to make this country a better place," she said.
The senator called Commonwealth head of state King Charles a "violent invader" with no grounds for sovereignty, still benefiting from the crown's colonisation of Australia over two centuries ago.
"Yes, he wasn't personally responsible, but he certainly relishes in the wealth that has been created on the backs of slavery on the backs of massacres and murderers and stolen children," she said.
The Queen's death in September sparked an outcry with reminders of the massacres and forced and ongoing marginalisation of Aboriginal and Torres Strait Islander people since British arrival.
"We want reparations. His (Charles') recent coronation saw millions of dollars being put into crowns and jewels that are all stolen from an Indigenous community somewhere in the world, So start giving it back," said Senator Thorpe.
The Victorian senator rejected claims she has fallen in line with federal opposition leader Peter Dutton and One Nation Senator Pauline Hanson because of her stance on the Voice, instead promoting Treaty as a means for more effective positive change.
"We're only one of a couple of Commonwealth countries in the world that does not have a treaty with its First People," she said.
"Treaty is about having equal power. At the moment, we are being dictated to by successive governments on what is best for us and how we should live our lives. I think that no matter what we need to fight for treaty."
Senator Thorpe said the Voice is "absolutely... not good enough".
Recent reports have emerged of her intention to quit politics at the end of her term.
