We have re-processed all the observations in the Parkes pulsar data archive obtained during the first four years of the Parkes multibeam receiver and have discovered two new fast radio bursts (FRBs) and five single pulse candidates (SPCs) from unknown sources, but with Galactic dispersion measures. These signals were only detected in a single beam of the receiver suggesting that they are unlikely to be terrestrial. There are no known pulsars in the pointing direction of the five SPCs and therefore are likely giant pulses from currently unknown pulsars. Using the Ultra Wideband Low (UWL) receiver we have opportunity to detect repeating signals from the two FRBs and to confirm the five SPCs. Our previous observations have obtained new detections for one of these targets and therefore confirming that source. Therefore we propose for more observation in an attempt to confirm the remainder and to study the newly discovered source.
