The world's largest nesting spot for endangered green sea turtles will be made over to stop baby turtles drowning and adults dying from heat exhaustion.

During nesting season about 60,000 female green turtles swim from Indonesia, Papua New Guinea, the Torres Strait and the West Pacific to Raine Island to lay their eggs.

Six Olympic-sized pools of sand will be moved across the island to raise the nesting area, while fences will be added around dangerous cliffs.

A rock formation dubbed "Death Rock", due to turtles becoming trapped under its overhangs and dying, will also be reshaped.
