The first team, from the Southern Cross Institute for Health Research (Morgan and Jalaludin, 2001), investigated the physical health impacts of air pollution. The team reviewed a large range of international and Australian studies that had applicability to the GMR airshed.

The results of both of these consultancies are reported in subsequent.
