title: Astrometry of southern radio sources.
abstract: An overview is presented of a number of astrometry and astrophysics programs based on radio sources from the Parkes 2.7 GHz catalogues.  The programs cover the optical identification and spectroscopy of flat-spectrum Parkes sources and the determination of their milliarc-second radio structures and positions.  Work is also in progress to tie together the radio and Hipparcos positional reference frames.  A parallel program of radio and optical astrometry of southern radio stars is also under way.
