Abstract	We report on a blind neutral hydrogen survey for galaxies using the 21 cm multibeam receiver on the Parkes 64 m telescope. The surveyed region covers \|b\|<=5 deg in the zone of avoidance (ZOA) from Galactic longitude 308 deg to 332 deg. The survey represents the first phase of a blind H I survey covering the southern ZOA (l=212 deg to 36 deg). We have detected H I in 42 galaxies above a 3 σ limit of 60 mJy. The galaxies detected in this survey have velocities out to 6000 km s^-1 and H I masses in the range 4x10⁷ to 3x10¹⁰M_solar (h^-2₇₅). Only eight of the 42 galaxies have velocities previously measured. A further nine galaxies appear to have optical counterparts in the Woudt's 1998 catalog. In total, 16 of the galaxies appear to be associated with IRAS sources, although only three of these are without optical counterparts. The estimated median extinction for the 20 galaxies with optical or IR counterparts is A_B=3.8 mag. For the 22 galaxies with no counterparts, the estimated median extinction is A_B=5.6 mag. The distribution of galaxies is suggestive of a connection between the Centaurus supercluster above the Galactic plane and the Pavo-Indus supercluster beneath the plane. No previously hidden concentrations of galaxies were found.
