Traces of asbestos are being found on beaches in Darwin.

Locals believe the asbestos has been on the beaches for years, following the dumping of household debris near the coastline.

There are signs on beaches that warn people of the potential asbestos hazards, but locals consider these to be insufficient warnings.

No extensive effort has been made to remove the asbestos, but a representative of the Darwin Council has encouraged people to report large pieces to the Northern Territory government.
