This paper discusses and describes one of the new optical search strategies that have come on-line in the last few years. Armed with a $DLR250,000 optical SETI observatory built mainly through private sector funds and other off- campus telescopes the OZ OSETI Project is searching for very fast optical pulses beamed at planet Earth by Extraterrestrial Intelligence civilizations which have surpassed the radio threshold. The search has initially concentrated on southern circumpolar stars and globular clusters.
