  Compact Steep Spectrum (CSS) and Gigahertz Peaked Spectrum (GPS) sources are
classes of compact, powerful, extragalactic objects. These sources are thought
to be the earliest stages in the evolution of radio galaxies, capturing the
ignition (or, in some cases, re-ignition) of the AGN. As well as serving as
probes of the early stages of large-scale radio sources, these sources are
good, stable, amplitude calibrators for radio telescopes. We present an
unbiased flux density limited (>1.5 Jy at 2.7 GHz) catalogue of these objects
in the Southern Hemisphere, including tabulated data, radio spectra, and where
available, optical images and measurements. The catalogue contains 26 sources,
consisting of 2 new candidate and 15 known CSS sources, and 9 known GPS
sources. We present new Australia Telescope Compact Array (ATCA) data on ten of
these 26 sources, and data on a further 42 sources which were excluded from our
final sample. This bright sample will serve as a reference sample for
comparison with subsequent faint (mJy level) samples of CSS and GPS candidates
currently being compiled.
