Western Australia tightens Alcoa mining conditions near Perth reservoirs and cockatoo habitat
Published · Updated
What happened
The Western Australian government increased environmental buffer requirements for Alcoa's mining near Perth water reservoirs and black cockatoo nesting trees as part of its assessment of jarrah forest operations. The revised order applies immediately and leaves open the option of additional restrictions.
Why it matters
The order changes the operating conditions for a large miner in a sensitive catchment and habitat area, raising the chance of production changes, compliance costs, and further regulatory action in coming days. It also provides a live test of how state governments balance resource extraction, drinking-water protection, and biodiversity rules.
Western Australia on 29 October imposed tougher conditions on Alcoa's jarrah forest mining operations, including wider buffers around Perth drinking-water reservoirs and black cockatoo nesting trees. The move came through the state's environmental assessment process and took effect immediately. Premier Roger Cook also indicated that further restrictions could follow, putting near-term focus on whether the state adds conditions, slows approvals, or forces operational changes at affected mine areas.
