The Waitsia Gas Field encompasses the Xyris Production Facility, the Waitsia Gas Plant, multiple production wells, and an integrated network of gathering systems, flowlines and hubs that transport extracted gas for processing.
Located approximately 16 kilometres southeast of Dongara and 350 kilometres north of Perth, the Waitsia Gas Field plays an important role in supporting energy supply and economic development across the Mid West region and Western Australia. The project contributes regional value through local employment, community investment and opportunities for local businesses and suppliers.
Waitsia Gas Field was developed in two stages. Stage 1 commenced production in 2016, establishing the initial processing and export capability. Stage 2 achieved First Gas in December 2025 and is a 250 TJ/day capacity facility connected to production wells and supporting infrastructure. Â
The Waitsia Gas Field is a conventional gas reservoir located on privately owned agricultural land. The Waitsia Joint Venture is a 50:50 partnership between Mitsui E&P Australia and Beach Energy for Permit Areas L1 and L2, with Mitsui E&P Australia as the Operator.

Stage One
Xyris Production Facility
The Xyris Production Facility has been operating since 2016 and has a maximum processing capacity of approximately 30 terajoules per day (TJ/day). The facility supplies natural gas to the Western Australian domestic market via the Dampier to Bunbury Natural Gas Pipeline (DBNGP), supporting reliable energy delivery across the state.
During the initial development phase, more than $6 million in service contracts were awarded to Mid West businesses delivering core project services, including pipeline construction, earthworks, concreting, and electrical and instrumentation works. Local service providers played a key role in delivering the project safely, on schedule and within budget.
Xyris Gas Plant Expansion
The 2020 Expansion Project for the Xyris Gas Plant Facility to refurbish the facility and connect it to the DBNGP awarded more than $2 million to local contractors to provide construction services. In addition, local contractors were engaged for road maintenance, cleaning, minor earthworks and communications.
Stage 2
Waitsia Gas Plant
The Waitsia Gas Plant and associated gas gathering pipelines extend across an area of approximately 10 kilometres in radius and is located adjacent to the Xyris Production Facility. The plant forms the central processing hub for gas produced from the Waitsia field, integrating production wells and supporting infrastructure through a connected network of flowlines and facilities.
Gas from the plant is exported to the DBNGP and sold to domestic users with the balance processed through the Karratha Gas Plant and sold as LNG to the international market.
All the major units of the Waitsia Gas Plant were built in Western Australia by specialist fabrication companies and trucked to site – the largest of the modules weighed in at 45 tonnes and stands 34m tall. During 2023-24 peak construction, the project created 39 regional jobs and supported 705 jobs statewide.
Waitsia Gas Project Stage 2B
Waitsia Gas Project Stage 2B reached Final Investment Decision (FID) by the Waitsia Joint Venture in October 2025. The project includes connecting three additional wells, which would be tied-back via new flowlines to the Waitsia Gas Plant.
These activities will occur on private agricultural land or at existing well pads that have gas infrastructure in place or adjacent to them.
