Campbelltown UWS Rotary Observatory

Campbelltown UWS Rotary Observatory in Campbelltown, New South Wales, Australia, was opened in 2000 and is owned by Western Sydney University. It consists of twin domes of 4.5-metre and 2.9 metre diameter.

The observatory is used for research and is the home of the Australian Optical SETI (OZ OSETI) Project. It is the only dedicated optical SETI project in the Southern Hemisphere. It is searching for nanosecond laser pulses from outer space with very sensitive and sophisticated equipment. In December 2008, it picked up a mysterious pulsed laser look alike signal from outer space.

The observatory is also used for Advanced Engineering student projects. One of the domes is being developed as a robotic observatory.

The Observatory can be seen from Main Ridge Park in Macarthur Heights.
