On 9 December 2010, the AEMC gave notice under sections 311 and 313 of the National Gas Law of the making of the "Timetable for Prescribed Gas STTM Reviews" Rule and Rule determination.

In its final Rule determination, the Commission decided to make the Rule proposed by AEMO with minor amendments. The Commission made the Rule as it was satisfied that the Rule will or is likely to contribute to the achievement of the National Gas Objective.
