What Osaka Gas Australia does
Osaka Gas Australia Pty Ltd (OGA) is a wholly owned subsidiary of Osaka Gas Co., Ltd. (Daigas Group), established in 2000 and headquartered in Perth, Western Australia. OGA operates as an upstream energy investment and asset management entity, holding participating interests in four upstream oil and gas projects across Australia and Timor-Leste. Its portfolio comprises three core assets: the Greater Sunrise gas fields (10% interest, pre-development, Timor Sea), the Gorgon LNG project (1.25% interest, operating, Carnarvon Basin, with Stage 3 expansion under Final Investment Decision in December 2025), and the Ichthys LNG project (1.2% interest, operating, Browse Basin, with an additional 1.2% interest in the adjacent AC/RL7 block under acquisition).
OGA's revenue mechanics are anchored in equity participation in LNG production — Gorgon delivers 15.6 million tonnes/year of LNG capacity and Ichthys 8.9 million tons/year — with the majority of production directed to the parent Osaka Gas for resale into the Japanese market. The company's stated mandate is to secure long-term stable LNG supply underpinning Osaka Gas' core business and the Daigas Group's global expansion.
In recent years OGA has pivoted part of its strategy toward decarbonization, pursuing biomethane production (Griffith Biohub targeting 460 TJ/year in phase 1, scaling toward 10 PJ/year by 2030), e-methane via Pre-FEED work with Santos, Tokyo Gas, and Toho Gas at Moomba in the Cooper Basin, green hydrogen studies with AGL, and concentrated solar thermal development with FPR Energy. These initiatives are pre-commercial or early-stage and represent optionality rather than current revenue. As a privately held subsidiary, OGA does not publicly disclose revenue or financial statements.
