The first deep catalog of the H I Parkes All Sky Survey (HIPASS) is presented, covering the south celestial cap (SCC) region. The SCC area is ~2400deg^2^ and covers {delta}<-62{deg}. The average rms noise for the survey is 13 mJy/beam. Five hundred thirty-six galaxies have been catalogued according to their neutral hydrogen content, including 114 galaxies that have no previous catalogued optical counterpart. This is the largest sample of galaxies from a blind H I survey to date. Most galaxies in optically unobscured regions of sky have a visible optical counterpart; however, there is a small population of low-velocity H I clouds without visible optical counterparts whose origins and significance are unclear. The rms accuracy of the HIPASS positions is found to be 1.9'. The H I mass range of galaxies detected is from ~10^6^ to ~10^11^M_{sun}_.
