Perth Basin (Waitsia)

Beach's Perth Basin gas position in Western Australia, centred on the Waitsia gas project (250 TJ/day Waitsia Gas Plant) and Beharra Springs, developed in a joint venture with Mitsui. The Waitsia Gas Plant was constructed and first LNG cargoes were delivered during FY25 via the North West Shelf facilities at Karratha. FY25 production was 1.6 MMBOE. Net-to-Beach 2P reserves are 67.4 MMBOE (gas 392 PJ), the largest single-asset 2P position in the portfolio; the Beharra Springs Deep 3 well result indicated pressure communication across the field, contributing to a downward 2P revision during the year. 2C contingent resources are 6.1 MMBOE.
