Since the eighties we have begun, in Brazil, a search for Post-T Tauri stars. Here we describe the main steps of this research that resulted in the discovery of the nearby TW Hya and Horologium associations. A very recent survey resulted in the detection of three different kinematical groups: 1) the Great Austral Young Association, which is a very extended complex region involving the Horologium and Tucana associations, 2) a CrA extend association and 3) a new group in Pisces.
