The NT Environment Protection Authority (NT EPA) has given environmental approval to the Santos Darwin Pipeline Duplication Project.

The Environment Protection Act 2019 mandates an environmental impact assessment and separate environmental approval for all projects with significant environmental impact potential.

Santos is developing the Barossa Gas Export Pipeline to transport gas from the Timor Sea’s Barossa reservoir to Darwin, with the NT EPA assessing the Santos Darwin Pipeline Duplication Project in Northern Territory waters.

The pipeline duplicates a Bayu-Undan pipeline section, allowing Santos to reuse it for transporting CO2 to the depleted Bayu-Undan reservoir for sequestration.


The NT EPA assessed the project’s potential impacts on the marine environment, culture, heritage, and greenhouse gas emissions.

The environmental approval outlines conditions to manage potential environmental impacts to an acceptable level.

“The Santos Darwin PipelineDuplication project has been through a rigorous environmental assessment by the NT EPA. I have applied the NT EPA’s recommended conditions and granted the environmental approval,” Minister for Environment, Climate Change and Water Security Kate Worden said.

“The Territory Government has supported this project from the beginning. Gas will play a critical role in supporting our transition to renewables, ensuring ongoing energy security for Territorians as we head towards net zero.”

The Barossa Gas project, worth $6.4 billion to the NT economy, is expected to generate 600 local jobs through construction and hundreds more over the next two decades.

Minister for Mining Mark Monaghan said the State is well-positioned to become a global leader in low-emissions energy exports.

“The $6 billion Barossa Gas project is significant for the Territory’s economy and secures hundreds of local jobs for the next two decades, all while being pivotal in the world’s transition to a cleaner, greener future.”
