Nearly three thousand people [2,638] from 64 villages along the Sepik River in Papua New Guinea have taken action to stop a huge copper/gold mining project.
The project is planned at the head waters of a vital waterway by PanAust, the Australian subsidiary of a Chinese Government owned company.
The complaint has been lodged with the Australian National Contact point for the OECD.
The communities are represented by Project Sepik Inc and environmental campaigners, Jubilee Australia.
