Union Vote Triggers Strike Threat at Premier Coal, WA Grid’s Main Supplier

After union negotiations with Yancoal Australia broke down, workers at Premier Coal voted to take protected industrial action, targeting the mine that feeds Synergy’s Muja and Collie power stations 200 km south of Perth. The strike demand focuses on higher wages, clearer redundancy arrangements and certainty ahead of Western Australia’s plan to retire coal-fired generation by 2030. State officials assert that Synergy’s coal stockpiles will prevent any interruption to the grid, but union secretary Steve McCartney cautioned that prolonged action could cause disruptions.

The dispute follows recent announcements that the mine will cut 70-100 jobs and that the government will allocate over $700 million, including $3.2 million for affected workers, to support the transition and mine rehabilitation. Critics, including Shadow Energy Minister Steve Thomas, argue the government is favoring state-owned power stations while neglecting mine workers. Negotiations on strike timing are ongoing, with unions prepared for stoppages longer than 12 hours.
