Climate change is lapping at the shores of Poruma, a tropical island in Australia’s Torres Strait. It is a dot in the Pacific Ocean, just two kilometres long and 300 metres wide, that sits halfway between the northern tip of Australia and the south of Papua New Guinea. Christianity came to the Torres Strait in the late 1800s and it has been embraced by the Islanders. But when the people of Poruma gained this faith, they lost parts of their culture and language. Siobhan Hegarty journeys to the Torres Strait where the locals are fighting to save their land, their language and their cultural traditions – before it’s too late.
