On 25 August 2011, the Commission published a Rule to enable participants in the Declared Wholesale Gas Market (DWGM) to better manage their financial risks. Its key purposes are to allow participants to renominate their AMIQ profiles and renominate AMDQ between system injection points during the gas day, and to provide for participants to nominate injection hedges and agency injection hedges collectively to close proximity injection points.

The Rule as Made also amends the definition of close proximity injection points and allows DWMG participants to submit their injection hedge nominations, agency injection hedge nominations and AMIQ profiles to AEMO up to one hour before the start of the gas day.
