A catalogue of 297 radio sources between declinations -20° and -60°, has been compiled from observations with the Australian 210-ft telescope. The sources were selected from a survey at 75 cm wavelength as having flux densities in excess of 4 X 10-26 W m-2(cJs)-1. The survey did not cover a small area near the galactic plane. Additional measurements were made at wavelengths of 21 and 11 cm. Results on source identification, spectra, and polarization are discussed.
