We present molecular line imaging observations of three massive molecularoutflow sources, G333.6-0.2, G333.1-0.4, and G332.8-0.5, all of which also showevidence for infall, within the G333 giant molecular cloud (GMC). All three arewithin a beam size (36 arcseconds) of IRAS sources, 1.2-mm dust clumps, variousmasing species and radio continuum-detected HII regions and hence areassociated with high-mass star formation. We present the molecular line dataand derive the physical properties of the outflows including the mass,kinematics, and energetics and discuss the inferred characteristics of theirdriving sources. Outflow masses are of 10 to 40 solar masses in each lobe, withcore masses of order 10^3 solar masses. outflow size scales are a few tenth ofa parsec, timescales are of several x10^4 years, mass loss rates a few x10^-4solar masses/year. We also find the cores are turbulent and highly supersonic.
