Human Rights Law Centre, representing 156 Bougainville community members, have filed a complaint with the Australian Government against Rio Tinto for environmental and human rights violations caused by its former mine on Bougainville in Papua New Guinea.

Rio Tinto, which was forced to suspend operations at Panguna due to the civil war in 1989 and divested its interest in 2016, acknowledged the filing of the complaint by the Panguna communities and said it was "ready to enter into discussions" with them.
