  A small sample of 7 southern Compact Steep Spectrum (CSS) radio sources has
been selected as part of the study of a larger flux-limited complete sample of
radio sources. High resolution images, using the VLBI network in the southern
hemisphere and the high resolution MERLIN array, are presented for all sources
in the CSS sample. The overall morphology of each source consists of
well-defined double lobes but with substantial diffuse and extended components
present. In the majority of cases only a fraction of the total flux density is
detected on the VLBI baselines, indicating the presence of larger extended
radio structures. However, all sources are unresolved at arcsecond scales and
are of sub-galactic size, with linear size in the range 0.1-2 kpc. The radio
properties of the sources agree well with CSS sources in other samples.
