The Coordinator of Energy (Coordinator), in consultation with the Gas Advisory Board (GAB), is undertaking a review of the Gas Services Information (GSI) Rules.
There are two key drivers for the Review: the recent Inquiry into the WA Domestic Gas Policy (the Inquiry), and proposed changes to the National Gas Law (NGL) and National Gas Rules (NGR) as they may apply in Western Australia.
The purpose of this Review is to:
- assess the GSI Rules in the context of the four recommendations from the Inquiry, which were supported by the WA Government, and propose any necessary amendments or clarifications to the rules aimed at achieving the intent of the recommendations;
- ensure consistency with provisions in the NGL and NGR in light of a proposal to adopt certain new information disclosure requirements for pipelines and blend processing, compression and storage facilities under the NGL; and
- evaluate additional aspects of the GSI Rules that may require clarifications or amendments.
The GAB has established the GSI Rules Review Working Group (GSIRRWG) to support the Coordinator’s review.
Papers and detailed minutes of the GSIRRWG meetings are published on the GSIRRWG page and the relevant GAB papers and minutes are available on the GAB webpage.
Consultation Paper
As part of the review process, the Coordinator of Energy published a Consultation Paper on 15 December 2025 with proposed Review Outcomes aimed at strengthening the GSI Rules framework, by promoting market transparency and the quality of accuracy of reported information through the WA GSOO and the Gas Bulletin Board (GBB).
The window for submitting feedback on the Consultation Paper closed at 5:00pm on 9 February 2026. Stakeholder submissions received are available below.
Information Paper
Following consideration of stakeholder submissions on the Consultation Paper, the Department of Energy and Economic Diversification (DEED) published the Coordinator's Information Paper with the Review Outcomes on 28 October 2026. The Information Paper also includes a summary of the consultation submissions and DEED’s responses.
The Review Outcomes include:
- formalising improvements to the WA GSOO;
- amending GSI Rules definitions to address inconsistencies in how information is reported;
- adopting principles from the NGL reforms to enhance accuracy of information reporting;
- introducing a public register for the Economic Regulation Authority’s investigations; and
- increasing awareness of domestic gas reporting obligations by providing a link to the WA Domestic Gas Statement on the GBB.
Further Consultation Paper: Improving coordination between Gas Pipeline Operators and the Australian Energy Market Operator
On 25 August 2025, the Australian Energy Market Operator (AEMO), as the Market Operator and System Operator in the Wholesale Electricity Market (WEM), was required to intervene in the Real-Time Market to maintain power system security and reliability by dispatching Gas-Powered Generation (GPG).
The event highlighted the increasing interdependence between the operation of the WEM and the gas pipelines, and the need for enhanced coordination and information sharing arrangements to support whole-of-system reliability.
DEED, in consultation with AEMO and Gas Pipeline Operators, has developed proposed measures to strengthen coordination and information sharing between the Gas Pipeline Operators and AEMO, where:
- AEMO must provide electricity information to Gas Pipeline Operators daily to support effective pipeline operations;
- Gas Pipeline Operators must provide gas pipeline information to AEMO if requested, to assist AEMO in maintaining reliability in the WEM;
- AEMO must advise Gas Pipeline Operators if it declares a Low Reserve Condition in the WEM, providing early warnings to Gas Pipeline Operators that GPG consumption may change;
- Gas Pipeline Operators must advise AEMO if the gas consumption of Registered Large Users in the electricity Consumption Category will be curtailed, assisting AEMO to maintain reliability in the WEM; and
- AEMO may advise the Coordinator of Energy that it considers that an Emergency Management Facility direction is required if the WEM is in an Emergency Operating State, to prevent cascading problems in the energy sector.
Stakeholders are invited to provide written feedback on the Consultation Paper before 5:00pm (AWST) on 25 November 2026 by submitting comments to energymarkets@deed.wa.gov.au. Late submissions may not be considered.
Any submissions received will be published, unless confidentiality is specifically requested.
