  We present preliminary results from a study of the neutral hydrogen (HI)
properties of an X-ray selected sample of nearby loose galaxy groups. This
forms part of a multi-wavelength investigation (X-ray, optical and radio) of
the formation and evolution of galaxies within a group environment. Some
initial findings of an ATNF Parkes Multibeam wide-area neutral hydrogen imaging
survey of 17 nearby galaxy groups include two new, potentially isolated clouds
of HI in the NGC 1052 and NGC 5044 groups and significant amounts of HI within
the group virial radii of groups NGC 3557 and IC 1459 - two groups with complex
X-ray structures that suggest they may still be in the act of virialisation.
Here we present ATCA high-resolution synthesis-imaging follow-up observations
of the distribution and kinematics of HI in these four groups.
