  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 arcseconds) of IRAS sources, 1.2-mm dust clumps, various
masing species and radio continuum-detected HII 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 to 40 solar masses in each lobe, with
core masses of order 10^3 solar masses. outflow size scales are a few tenth of
a parsec, timescales are of several x10^4 years, mass loss rates a few x10^-4
solar masses/year. We also find the cores are turbulent and highly supersonic.
