A non government organisation in Papua New Guinea, LNG Watch, says the Exxon Mobil LNG project is progressing well because locals are essentially being forced into submission by police and security forces.
Australia's Prime Minister, Tony Abbott, is to be briefed on the project when he visits Papua New Guinea this week.
It is is understood to be ahead of schedule in terms of delivering it's first cargo of liquefied natural gas this year.
LNG Watch's Stanley Mamu says ExxonMobil is not concerned with biodiversity, making landowners happy, or compensating them fairly.
"They just pay them off and then bulldoze the project. Police and defence force, they use force to move the project. and they use force to pay the environment, whether they like it or not, they use force to get in there, and I know that the project is moving now, due to that."
Stanley Mamu is also warning of possible future clashes as he's seen clans bring in more guns to Hela because they're unhappy with how they're being treated.
