New research has found undisturbed artefacts under the seabed off the Northern Territory coastline which could tell the stories of how the first people arrived to Australia.

Flinders University said submerged landscapes around islands hold ancient tools, structures, burial sites and rock art from thousands of years ago, when sea levels were lower.

The university noted Northern Territory’s importance, as it once held an inhabited shelf of land which stretched all the way to Papua New Guinea.
