In these proceedings, Koribalski presents redshift slices of galaxies detected in the HI Parkes All-Sky Survey (HIPASS). In this contribution, we study the spatial and mass distribution of HIPASS galaxies from a statistical point of view, using the two-point correlation and mass functions. Comparison with optical samples (2dFGRS) reveals that gas-rich galaxies are relatively unclustered. A real-space correlation length of 3.2± 0.4 h100-1 Mpc is measured for HIPASS galaxies (Meyer 2003), compared with 5.1±0.3 h100-1 Mpc for 2dFGRS galaxies (Hawkins et al. 2003). Low-mass HIPASS galaxies have the smallest clustering strength, even compared with the faintest late-type optical samples. However, the difference in clustering strength with late-type optical samples appears to be most marked when comparing the highest HI mass galaxies and the brightest 2DFGRS galaxies. Processes which can lead to large systematic difference for objects of the highest mass are discussed. The HI mass function of galaxies is also discussed, again with an emphasis on the highest mass objects, including the most massive galaxy so far discovered in HIPASS and Parkes ZoA surveys, HIZOA J0836-43.
