The astronomers will be based at the $20 million Cooperative Research Centre at Mount Stromlo.
Cooperative Research Centre chief executive Ben Green said scientists estimated more than 300,000 pieces of space junk were orbiting the Earth and they posed serious risks to satellites and space exploration.
Director of the ANU Research School of Astronomy and Astrophysics, Professor Matthew Colless, said that before debris could be removed "we must find out how much space junk there is and then track it all".
"If we know where the space junk is then satellites can avoid it," he said.
"Our long-term goal is to use a high-powered laser to push the space debris gently back into the Earth’s atmosphere."
The Mount Stromlo Observatory will play a leading role in monitoring the debris and any future laser activity.

In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula's center measures about 50 light-years across, lies about 4,500 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros).
' ... "All bright galaxies within 20 million light years, including us, are organized in a 'Local Sheet' 34-million light years across and only 1.5-million light years thick," says McCall. "The Milky Way and Andromeda are encircled by twelve large galaxies arranged in a ring about 24-million light years across – this 'Council of Giants' stands in gravitational judgment of the Local Group by restricting its range of influence." ...

"To laugh often and much;
to win the respect of intelligent people and the affection of children;
to earn the appreciation of honest critics and
to endure the betrayal of false friends.
To appreciate beauty;
to find the best in others;
to leave the world a bit better whether by a healthy child, a garden patch, or a redeemed social condition;
to know that even one life has breathed easier because you have lived.
This is to have succeeded."
