AbstractStatistical overdensities of radiosources in the Sydney University Molonglo Sky Survey (SUMSS) are used as signposts to identify high-redshift clusters of galaxies. These potential clusters have been observed at 20 and 13 cm at the Australia Telescope Compact Array (ATCA) to obtain better positional accuracy for the sources. A subsample have been imaged in V, R and I at the 2.3-m telescope at Siding Spring and in J and K at the Anglo Australian Telescope (AAT) and the New Technology Telescope (NTT) at La Silla, Chile. The colours obtained from these observations will be used to estimate redshifts for the potential cluster members.
