National Gas Rules
Version 59
Status Information
This is the latest electronically available version of the National Gas Rules as at 27 May 2021.
This consolidated version of the National Gas Rules was last updated on 27 May 2021 as a result of the commencement of the following amendment:
National Gas Amendment (Minor changes 2) Rule 2021 No. 1
This consolidated version of the Rules reflects the initial Rules made by the SA Minister under section 294 of the NGL as amended by:
Rules made by the South Australian Minister under sections 294A to 294F of the NGL; and
Rules made by the Australian Energy Market Commission under Chapter 9, Part 3 of the NGL.
Application of the National Energy Customer Framework related Rule
On 27 June 2012, the South Australian Minister made Rules relating to the implementation of the National Energy Customer Framework (NECF), including amendments to the National Gas Rules under section 294C of the NGL (NECF related Rule). The NECF related Rule commenced operation as a law of Tasmania, the Australian Capital Territory and the Commonwealth on 1 July 2012; South Australia on 1 February 2013, New South Wales on 1 July 2013 and Queensland on 1 July 2015.
The NECF related Rule does not apply in Victoria, Western Australia or the Northern Territory until the National Energy Retail Law set out in the Schedule to the National Energy Retail Law (South Australia) Act 2011 is implemented as a law in that jurisdiction (clause 88, Part 13, Schedule 3 NGL). The NECF related Rule can be found on the Australian Energy Market Commission's website under the 'National Gas Rules', 'Rules made by the SA Minister' tabs.
