Pauline Hanson wants to celebrate the strict immigration policy of an isolated Indian tribespeople who killed a young American evangelist.
The One Nation leader will move a motion in the Senate on Tuesday calling for the upper house to support the desire of the Sentinelese people to protect their culture and way of life.
The Sentinelese people live on their own small forested island and are known to resist all contact with outsiders, often attacking anyone who comes near.
John Allen Chau, 26, was killed by members of the community last week when they reportedly attacked him with bows and arrows.
Senator Hanson's motion calls for her colleagues to back the people of North Sentinel Island's "strict zero-gross" immigration policy.
"The Sentinelese people of the remote North Sentinel Islands are likely the last pre-Neolithic tribe in the world, and possess a unique culture and way of life that should be cherished and protected," the motion says.
"Even small levels of migration would have a devastating and irreversible effect on the beautiful and unique culture and way of life of the Sentinelese people."
Senator Hanson tweeted the motion, questioning whether the Senate would support the "proud" Sentinelese people's strong border protections or condemn their "intolerant immigration policies" and "lack of diversity".
"We'll have to wait & see!" the One Nation leader posted.
