We have an ongoing programme using Mopra molecular line data to investigate the role played by turbulence in triggering and regulating star formation in the G333 giant molecular cloud. To make a comprehensive assessment of this role, we also require information on the effect of local magnetic fields and the feedback effect of bipolar outflows from YSOs within the cloud. There are 5 sources of polarized mainline OH maser emission in the cloud, in proximity both to UCHII regions and sources of bipolar molecular outflows in the Mopra data. We wish to use the LBA to observe the OH masers in full polarization mode to measure the magnetic field strengths and structures that give rise to the polarization. This will enable both a determination of the magnetic energy available for support against turbulence-induced collapse, and an investigation into magnetic collimation effects in the outflows. The sub-arcsec resolution spatio-kinematic data will permit a study of the outflows themselves and a determination of whether the masers lie in the outflow or in a collimating disk. This is part of a co-ordinated, multi-wavelength, international campaign to study star formation in the G333 cloud.
