The laser tracking system would work by giving space craft and satellites, which are able to be maneuvered, time to move out of the way of an incoming chunk of debris.

The Australian government said the technology was part of the country's "proud history" in space science and research.

The Canberra-based team says it has received interest from around the world. Its ultimate aim is to build a series of laser tracking stations in various countries to provide a defensive shield for activity in space.

They warn that the amount of junk in Earth's orbit is increasing and, as it does, the risks to satellites and space vehicles, also rise.

The project is part of an international consortium. Other members of the consortium include the Australian National University and other institutions in Germany and the United States.
