We present molecular line imaging observations of three massive molecular outflow sources, G333.6-0.2, G333.1-0.4, and G332.8-0.5, all of which also show evidence for infall, within the G333 giant molecular cloud (GMC). All three are within a beam size (36 arcsec) of IRAS sources, 1.2-mm dust clumps, various masing species, and radio continuum-detected H II regions and hence are associated with high-mass star formation. We present the molecular line data and derive the physical properties of the outflows including the mass, kinematics, and energetics and discuss the inferred characteristics of their driving sources. Outflow masses are of 10^–40 M_☉ in each lobe, with core masses of the order of 10³ M_☉. Outflow size scales are a few tenth of a parsec, time-scales are of several x10⁴ years, mass-loss rates a few x10^–4 M_☉/yr. We also find the cores are turbulent and highly supersonic.
