Union workers at BHP’s Port Hedland iron ore facility in Western Australia conducted a two-day strike over the weekend. This action marks the first major industrial dispute at the site in more than 20 years.

Approximately 150 workers participated in the stoppage. The strike began August 8 with a 24-hour ship-loading ban, followed by a full work stoppage on August 9.

The dispute centers on a new four-year collective bargaining agreement following months of failed negotiations. BHP reported that operations continued and vessels were loaded throughout the weekend despite the action.

Both parties are scheduled to resume negotiations with the Fair Work Commission on August 18. BHP is expected to present an updated proposal during that session.
