Australian LNG player Woodside has signed a deal with aluminum producer Alcoa to deliver domestic natural gas from its Western Australian operations.
Woodside said on Tuesday that the sale and purchase agreement with Alcoa includes the supply of 31.1 petajoules of domestic gas from 2027 to 2030.
The agreement follows the Western Australian state government’s approval in December 2025 extending the operation of the Pluto-Karratha gas plant interconnector.
Woodside noted that approval enables additional Pluto-sourced gas to be processed using existing capacity at the Karratha gas plant and brought to market quickly as new contracted domestic supply.
“This gas will be supplied to Alcoa’s Western Australian refineries, which provide thousands of local jobs and produce alumina, the feedstock for aluminum, a key material for the construction, manufacturing, and energy sectors,” Woodside executive VP marketing and CCO Mark Abbotsford, said.
“The agreement again demonstrates the Western Australian domestic market is operating in a way which supports both gas producers and consumers. It also underlines the ongoing effectiveness of Western Australia’s domestic gas policy in providing stable and predictable policy settings that underpin the delivery of gas to major industrial users,” he said.
The company has supplied domestic gas to Western Australia for more than 40 years.
In 2025, Woodside’s share of Western Australian natural gas production was 90.3 petajoules, representing approximately 21 percent of the state’s domestic gas supply, according to Woodside.
