CSR Activities of Coal Mines

Idemitsu Australia’s Boggabri Coal Operations produced a documentary video, “The Kamilaroi”, to provide a publicly available learning aid and a record of the key elements of the Kamilaroi traditional owners culture and stories, as recounted by local Kamilaroi people. This was an initiative championed by Boggabri Coal mine staff in partnership with members of the Kamilaroi nation.

The video was submitted to the 2019 annual New South Wales Mining Industry Awards and won the highly contested Community Excellence Award.

“The Kamilaroi” video was produced as a contribution to our community and to help preserve the unique and priceless culture of the traditional owners of the land on which Boggabri Coal Mine operates.
