The main cost in the LNG cargo from the swap would be the sales gas production cost from Waitsia Stage 2 to be produced later on to complete the swap. I think it will be less than $1 per GJ. Looking at these numbers the profit offset the BPT could make against contract obligation could be between $30m to $35m.
I am hoping that BPT can do at least 2 LNG cargo in the First Half of FY25.

From the December Quarterly Report dated 25/1/2024:


Waitsia LNG cargo

Production and stored volumes from the Xyris Gas Plant, together with third-party surplus gas sourced via a swap arrangement, enabled processing and lifting of the first Waitsia LNG cargo at the North West Shelf in December 2023.

Beach acquired Mitsui's 50% share and sold the cargo to bp under the terms of the previously announced LNG SPA. The cargo delivered revenue of $96 million and net cash proceeds to Beach of $49 million after purchase of Mitsui's share.

LNG sales were priced at $24 per MMBtu.

LNG in one cargo:

LNG volume 77.4 KT or 738 KBoe
BPT share 50%
