Spokesperson and Chairman of the Porebada Besena Association, Judah Matt Baru told Loop PNG that they haven't received any payment since the first shipment of the LNG in 2014.
He said the government has promised time and again to pay their royalties but has never kept those promises.
"We cannot sit and spectate on our own land. The government must come good with their promises or else we will shut the plant site for an indefinite period."
Baru said their petition was been given to the government but nothing has been forth coming.
