After the Rules had been operating for a number of years, Gas Industry Co began a policy review to build on operational experience, remove unnecessary compliance burdens and inefficiencies, and look for general improvements in the Rules and downstream reconciliation arrangements.
An Options Paper was released in December 2011 which sought feedback on a number of proposals to improve the Rules. Following feedback on the Options Paper it was decided to split the review into two parts: Phase I would address the proposals that had a good level of support in the Options Paper or were considered to be minor or technical changes, while Phase II would address options to improve the accuracy of the initial allocation. A working group, the Downstream Reconciliation Advisory Group (DRAG), was appointed to provide expert industry advice on the issues under review.
In December 2012, Gas Industry Co recommended to the Minister of Energy and Resources a number of changes to the Rules that were the culmination of Phase I of the review. The rule amendments were gazetted by the Minister on 28 February 2013 and took effect from 1 June 2013.
