Two major legal challenges have been launched to overturn the federal government’s approval of the extension of Woodside’s North West Shelf gas hub to 2070. The Australian Conservation Foundation (ACF) and Friends of Australian Rock Art (FARA) argue that Environment Minister Murray Watt failed to legally consider climate, emissions, and heritage factors.
Who’s taking the appeal — and on what grounds
ACF’s case: economics, emissions, and procedural error
- ACF contends that Minister Watt unlawfully factored in the projected economic benefits of a separate, yet-to-be-approved Browse gas project in justifying the extension decision.
- They argue key environmental data was omitted: the minister neglected to fully assess the greenhouse gas emissions of the extended operation, the downstream combustion emissions, and the risks of climate tipping points.
FARA’s challenge: protecting Murujuga rock art
- FARA argues the decision ignored the potential harm to Murujuga’s Indigenous rock art, a UNESCO-listed cultural site, by weakening environmental conditions after initial proposals.
- The group claims social, economic, and cultural impacts weren’t properly weighed, especially given weakened protections for acidic emissions and pigment damage in the rock carvings.
Government & Woodside defend the decision
- Woodside asserts the approval followed a protracted multi-year regulatory process involving both state and federal assessments.
- Minister Watt has emphasised that 48 strict conditions were imposed to mitigate risk to heritage and the environment, including emissions targets and monitoring regimes.
- The government also argues that under the EPBC Act, climate change impacts from combustion (Scope 3 emissions) are not required to be considered when approving projects.
Why these appeals matter
- Climate precedent: Courts may clarify whether future gas approvals must consider downstream emissions and climate risks.
- Heritage protection: The Murujuga rock art is among the oldest in the world; legal rulings could reshape how heritage and industry co-exist.
- Regulatory scrutiny: If courts find flaws, it may force the environment minister or Parliament to revisit the EPBC Act and assessment processes.
- Project delay risk: Legal challenges may delay or bring conditions that affect gas exports, contracts, and investment timelines.
Key dates & what to watch
- The appeals have just been filed; case scheduling and submissions will unfold in the coming months.
- Watch whether the court grants injunctions or interim relief to pause the extension.
- Monitor responses from traditional owners, conservationists, and state governments.
- Expect cross-examination of the 48 conditions — especially those relating to emissions cuts (60% by 2030, 90% by 2060) and their enforceability.
- Observe whether the court uses this case to hint at broader reforms to how gas and fossil fuel projects are assessed under Australian law.
