Results of variability observations of the southern extragalactic radio sources PKS 1610-771, PKS 1830-211 and the inner region of Centaurus A (Cen A) at 1.42 GHz are presented. Different light curves with temporal resolutions of minutes, 1 day and 1 month were obtained for each source. Significant variability was detected in PKS 1610-771 and Cen A. The implications of these results are discussed.
