  We report on neutral hydrogen observations of a ~ 5.5 x 5.5 degree field
around the NGC 1566 galaxy group with the multibeam narrow-band system on the
64-m Parkes telescope. We detected thirteen HI sources in the field, including
two galaxies not previously known to be members of the group, bringing the
total number of confirmed galaxies in this group to 26. Each of the HI galaxies
can be associated with an optically catalogued galaxy. No 'intergalactic HI
clouds' were found to an HI mass limit of ~ 3.5 x 10^8 Msun. We have estimated
the expected HI content of the late-type galaxies in this group and find the
total detected HI is consistent with our expectations. However, while no global
HI deficiency is inferred for this group, two galaxies exhibit individual HI
deficiencies. Further observations are needed to determine the gas removal
mechanisms in these galaxies.
