Abstract
We present multi-epoch VLBI observations of the methanol and water masers in the high-mass star formation region G 339.884-1.259, made using the Australian Long Baseline Array (LBA). Our sub-milliarcsecond precision measurements trace the proper motions of individual maser features in the plane of the sky. When combined with the direct line-of-sight radial velocity (vlsr), these measure the 3 D gas kinematics of the associated high-mass star formation region, allowing us to probe the dynamical processes to within 1000 AU of the core.
