A study of 12 compact radio sources (11 extragalactic and 1 Galactic) was conducted over a period of approximately 4 years with the Southern Hemisphere VLBI Experiment array. The main focus of this work has been on six nearby, bright, and compact radio sources which make up the Southern Hemisphere component of a ``Whole-Sky'' sample of such sources.
Particular emphasis has been placed on determining the structure and evolution in these sources at high spatial resolution and investigating relationships between the compact structure/evolution and emission at other wavelengths.
Results from the Southern Hemisphere study are summarised in the next section. Then a brief summary of the Northern Hemisphere sources, from already published results, is given and the overall VLBI properties of the ``Whole-Sky'' sample are considered.
