Western Australia Petroleum Legislation Amendment Act 2024
The Petroleum Legislation Amendment Bill 2023 (passed May 7, 2024) writes GHG transport and storage into three Western Australian statutes — the PGERA 1967 (renamed with GHG Storage), the Submerged Lands Act 1982 and the Pipelines Act 1969 — mirroring the Commonwealth OPGGS Act 2006. Two licensing paths lead to the GHG injection licence: direct access for petroleum/geothermal titleholders (no acreage release) and the exploration-permit-or-drilling-reservation path with work commitments; overlapping titles run on non-interference with DEMIRS-managed priority. Site closing mirrors the Commonwealth model with a 15-year closure assurance period before limited state indemnity. The regime answers Safeguard Mechanism demand (4.9% baselines) with state-waters storage for LNG-adjacent emitters — Gorgon-adjacent Barrow and North West Shelf geology under state, not Commonwealth, titles.
