One Nation Leader Pauline Hanson has given her support to the Sentinelese people for their “strict immigration policy”.

The inhabitants of North Sentinel, generally considered the last pre-Neolithic tribe in the world and strictly repels visitors, have made headlines across the world this month after killing a 26-year-old missionary who approached them on the island.

John Allen Chau was killed with bow and arrows after travelling to the island located in the Bay of Bengal, trying to convert the tribe to Christianity.

And on Tuesday, Ms Hanson revealed she will be asking the Senate “to acknowledge the terrible impact immigration would have on the Sentinelese people”.

Ms Hanson also questioned Labor and the Greens by speculating their stance on the matter.

“It will be interesting to see if Labor and the Greens are willing to support a country with such harsh immigration rules,” she wrote on Facebook.

“You would think they would be offended by the lack of diversity right?”

Ms Hanson’s announcement comes as authorities revealed they will most likely be abandoning their mission to retrieve Mr Chau’s body.

“The rights and the desires of the Sentinelese need to be respected and nothing is to be achieved by escalating the conflict and tension, and worse, to creating a situation where more harm is caused,” a group of anthropologists, journalists and activists said in a joint statement.

“They are a treasure… we cannot go and force our way in. We don’t want to harm them,” Dependra Pathak, the director general of police in Andaman and Nicobar islands, said.
