A review of the SETI activities in the southern hemisphere over the past three decades is made. A description of the META II program, that is carried out from the Instituto Argentino de Radioastronomia (IAR), and that is continuously scanning the southern skies is described. META (Megachannel Extraterrestrial Assay) is an 8.4 million channels spectrum analyzer with a spectral resolution of 0.05 Hz, working at the 1,420 MHz hydrogen line at the Oak Ridge Harvard radio-observatory and at IAR. A description of the first optical SETI observing program from the southern hemisphere is made. For this purpose a high temporal resolution device called MANIA (Multichannel Analyzer of Nanosecond Intensity Alterations) will be used at the 2.15 m telescope of CASLEO (Complejo AStronomico El LEOncito) in the San Juan province in Argentina.
