Abstract: Full WALLABY survey observations have now started on the Australian SKA Pathfinder in Western Australia, with the goal being to map at least half of the southern sky in HI to a redshift depth of z=0.1. I will summarise some of the first results from full WALLABY. This includes extensive insights into the interplay of ram pressure and tidal forces in the outskirts of large groups and dynamically young clusters, and the implications for galaxy transformation and evolution. I will also discuss synergies with other current and planned large-area multi-wavelength surveys as future implications for LSST and MeerKAT/SKA science directions. Combined with theoretical models, the coming decade is likely to see an improved understanding of the baryon cycle in galaxies and new constraints on the physics of gas accretion, cooling and galactic outflows.
