This report focuses on the potential impacts of mining upon surficial and groundwater flows and quality in the alluvial flood plains at its headwaters in the Namoi valley and the Darling Downs catchments.

The Senate Environment, Communications and the Arts Legislation Committee acknowledges other mining activity conducted in the Murray-Darling Basin (MDB), particularly mineral sand operations in the south of the MDB. However, based on the submissions it received, the committee judged that the primary matters of public concern are the impacts of coal mining and coal seam methane extraction in the Namoi Valley and Darling Downs catchments. The committee also heard evidence pertaining to the impact of mining on Australia's current and future food security. In accordance with standing order 25(13) the committee deferred to the Senate Select Committee on Agricultural and Related Industries on the issue of food security, which reported on its inquiry into food production in Australia on 26 November 2009.
