Campaigners gathered outside the WA Parliament House on Tuesday May 27, calling for the federal government to reject the North West Shelf.

Overview

  • Environment Minister Murray Watt granted Woodside Energy permission to operate its North West Shelf gas venture until 2070 under federal approval issued on May 28, 2025.
  • The approval comes with strict conditions on heritage protection at Murujuga and tighter air quality controls around the Burrup Peninsula facility.
  • Independent researchers estimate the prolonged project will emit about 4.3 billion tonnes of greenhouse gases by 2070, raising concerns about Australia’s net zero by 2050 commitments.
  • Indigenous custodians and environmental groups have staged protests and announced court action, citing damage to ancient rock art and cultural heritage.
  • The extension clears the path for Woodside’s planned Browse Basin development and underscores gas’s role in Australia’s energy security and domestic supply strategy.
