Researchers on expedition to Dauan Island heard two distinct frog calls in the rain and ‘sure enough, they were species new to science’

Three new animal species – two frogs and a gecko – have been discovered on a remote island in Australia’s north.

The animals were found on Dauan Island, a 3 sq km island in the far northern Torres Strait that is dominated by boulder fields.

Conrad Hoskin, an associate professor and terrestrial ecologist at James Cook University, described the new species after a research expedition to Dauan – the northernmost point of the Great Dividing Range.

“When you approach it, it just looks like a big triangle sticking out of the sea, and as you get closer, you realise you’re looking at … car- and house-sized granite boulders piled up.
