Query: Who refuses contact with outsiders on Sentinel Island?
Context: One such group is the Pila Nguru (Spinifex people) of Western Australia, whose habitat in the Great Victoria Desert has proved unsuitable for European agriculture (and even pastoralism).[citation needed] Another are the Sentinelese of the Andaman Islands in the Indian Ocean, who live on North Sentinel Island and to date have maintained their independent existence, repelling attempts to engage with and contact them.[citation needed]
