Kwinana Refinery to Close After 60 Years The Kwinana alumina refinery in Western Australia is closing permanently after more than six decades of operation. The facility has been a major part of the local industrial landscape since the 1960s. Why It’s Closing Alcoa says the refinery is too old, too expensive to run, and no longer competitive to restart. Production at the site was already curtailed in 2024, and studies into restarting the plant found no viable long-term path forward. Cost of the Shutdown Closing the refinery will cost around $890 million, with approximately $600 million expected to be spent over the next six years. These costs cover site closure, remediation, and long-term obligations. What Happens Next While the refinery itself will shut down, port and rail operations at Kwinana will continue. The site will be prepared for future redevelopment, marking the end of alumina refining at Kwinana but leaving the door open for new uses of the land.
