About
The WA Government intends to increase transparency in the WA domestic gas market, particularly on LNG exporters progress in meeting their domestic gas commitments under the (Policy), which is critical to support an efficient functioning gas market and effective operation of the Policy.
The WA Domestic Gas Statement (Statement) is designed to assist the operation of the WA gas market and the Policy by providing market participants with information on each domestic gas project, LNG exporters progress in complying with their 15% domestic gas reservation requirements, and how much gas is expected to be supplied in the WA market in the short to medium term.
The Department of Energy and Economic Diversification has worked with the Australian Energy Producers and its members to develop the Statement that provides information to the market on:
- Historical and expected gas supply by producer;
- Each domestic gas project;
- Each LNG exporter, including their obligation to supply the domestic gas market and strategy to meet their domestic gas commitment by end of field life and/or commitment life; and
- Each domestic-only producer, including how they're delivering volumes of gas into the domestic market.
The publication of the Statement responds to the findings from the recent Inquiry into the Policy, which called for increased market transparency.
The WA Government intends to update the Statement on an annual basis and in future will consider the inclusion of additional information such as demand data from major gas users.
The effectiveness of the Statement will be reviewed in 2026, with the Government to consider legislating the transparency measure if required.
Notes:
Devil Creek, Beharra Springs, Walyering, Macedon and Varanus Island are 100% domestic-only projects and therefore do not have a Domgas Commitment under the WA Domestic Gas Policy. Domgas commitment is indicative as of 31 December 2024.
All figures are reported in calendar years. Reporting of <1 PJ is reported to one decimal point.
For LNG projects, remaining domgas to be supplied includes the remaining commitment volume (PJ) and the daily rate of supply required to meet the commitment before end of field life and/or commitment life (TJ/d) subject to proponents' entitlement to the domgas plant’s nameplate capacity. For domestic-only projects this includes the estimated supply based on the remaining reserves.
These numbers are estimates and non-binding. Actual volumes are subject to factors including, but not limited to, volumes nominated by existing and future customers, planned and unplanned maintenance activities and future contracting activities.
Includes volumes executed during the negotiation of the North West Gas Development (Woodside) Agreement Amendment Act 2015 (42.743 PJ).
Woodside actively markets and makes volumes available comprising Western Australia Domgas on a portfolio basis including volumes from the North West Shelf, Pluto, Scarborough, Wheatstone-Julimar Brunello, and Macedon projects.
Includes equity volumes from Woodside's interest in Wheatstone - Julimar Brunello. Woodside's ownership in this asset is expected to end in 2026 following completion of the proposed asset swap with Chevron.
Other Pluto JV participants include MidOcean Pluto Pty Ltd and Kansai Electric Power Australia Pty Ltd, who sold their share of Pluto JV Domgas to Woodside in 2025.
The Pluto Domgas commitment requires that Woodside markets and makes available Domgas subject to commercial viability.
Currently 45 TJ/d of domestic gas supply infrastructure in place at the Pluto LNG facilities comprised of 25 TJ/d pipeline gas facility and approximately 20 TJ/d LNG truck loading facility.
This project has entered suspension of operations.
Proponent did not provide.
This figure reflects gross production from L11/L22 through the Beharra Plant, including from previous owners and JV parties. There is some uncertainty with this number given the long history and record keeping, but this should be considered a reasonable assessment.

State Agreement:
A legislated contract between the WA Government and proponents of major resources projects which has been ratified by an Act of the WA Parliament. State Agreements specify the rights, obligations, terms and conditions for development of the project and establish a framework for ongoing relations and cooperation between the State and the project proponent.
