Unions to strike at South32's Australian Al refinery

Workers demanding higher pay are set to strike on 10 November at Australian metals producer South32's 4.4mn t/yr Worsley alumina refinery in Western Australia (WA), in an action the company said will not affect production.

More than 200 of the Electrical Trades Union (ETU) and Australian Manufacturing Workers Union's (AMWU's) combined 256 members will take part in 48 hours of protected industrial action from tomorrow, both unions said on 9 November.

The strike is deliberately planned to coincide with maintenance at the refinery's high-temperature bauxite digester. Delays to the restart of the digester will impose irrecoverable losses on Worsley's alumina production, the ETU said.

South32 confirmed it is in enterprise agreement discussions with both unions and said no operational impacts are expected from the strike.

The unions said they are aiming to increase South32's workers' pay to match Alcoa's, as Alcoa prepares to acquire South32's bauxite, alumina and aluminium assets across Australia, South Africa and Brazil. The deal is expected to close in the first half of 2027.

Alcoa already operates WA's 4.2mn t/yr Pinjarra and 2.85mn t/yr Wagerup alumina refineries.

South32's attributable production at Worsley increased by 2pc on the year in July-September to 966,000t. The company has set a production guidance of 5.26mn t of alumina for its fiscal year ending 30 June 2027.
