An Aboriginal map detailing significant cultural information has been released for the Lake Eyre Basin, which spans 1.2 million square kilometres across inland Australia.

The map, which took 12 years to make, features songlines, historical trade routes and other cultural information about the basin, which covers 71 language groups.

Northern Territory member of the Lake Eyre Basin Community Advisory Committee, Brenda Shields, described the map as a 'living' treasure.

"It is based on Aboriginal culture and law, and with all of the Aboriginal tribes in the basin," Ms Shields said.

"It shows the living, breathing, eating and trading on country, and sharing stories and culture in general.”
