Globally significant gas reserves in the Beetaloo Sub-basin could propel advanced manufacturing, domestic supply security and cleaner energy production in Australia, while accelerating multibillion dollar growth in the Territory economy, with long-term global gas supply potentials of international significance.
The Beetaloo Sub-basin, 500km south east of Darwin, covers 28,000 square kilometres and is estimated to contain 500 Trillion cubic feet of gas (P50 gas-in-place resource as estimated by industry). That is just for the Velkerri B layer and does not include other known gas bearing geological layers.
Resource estimations are equivalent to more than 1,000 times the current annual domestic consumption in Australia, or the amount of energy required to drive a car 483 million kilometres.
Beetaloo Project Management Office
The NT Government has established the Beetaloo Project Management Office (PMO) as the central point in government to support and drive the development of the onshore gas industry in the Beetaloo Sub-Basin.
The PMO will deliver the significant and strategic planning needed to maximise the economic and community benefits of the Territory’s natural resources in the Beetaloo.
This coordination will ensure the Territory benefits from the growth and diversification of industry in the Beetaloo, which will support energy security and the transition to net zero emissions in Australia and across our region.
The PMO is based within the Department of Mining and Energy, ensuring industry-specific expertise can be harnessed to expedite Beetaloo development. It is also strategically aligned with the Office of the Territory Coordinator, where support may be required through the Territory Coordinator Legislative Framework.
The opportunity
The highly prospective resources of the Beetaloo Sub-basin are being compared to the productive Marcellus Basin in the north east of the United States, and there are other layers and basins yet to be explored.
The estimated gas volumes would be sufficient to service and grow existing LNG export markets, secure domestic gas supply and propel low-emission advanced manufacturing in the Territory.
Current exploration aims to determine recoverable volumes of both wet and dry gas from the Velkerri B layer and Kyalla formation. Studies and industry analysis projecting that development could:
- produce 13,000+ jobs by 2040
- increase economic activity by $17+ billion
- spur advanced manufacturing opportunities and new low-emission industries in the Territory
- deliver cheaper and more reliable gas across Australia for decades to come
- provide an additional source of gas for Liquefied Natural Gas (LNG) export.
Exploration and appraisals continue to show encouraging results, and first gas is expected to start flowing from the Beetaloo Sub-basin at the end of 2025.
To date studies provided for the Australian and Northern Territory Governments have looked at determining the most efficient pathways to market, as well as potential challenges and opportunities for the basins development.
Planning
Infrastructure in the Beetaloo Sub-basin will require future development, including new or enlarged gas processing, pipeline infrastructure and enhanced supporting infrastructure (such as road, rail, aviation and utility infrastructure) which will also benefit other users in the region.
Studies and detailed planning have commenced to build an infrastructure corridor from Elliott to Darwin.
Formerly known as the Tennant Creek to Darwin Infrastructure Corridor, the Territory Energy Link is a proposed multi-user, multi-asset infrastructure corridor which aims to deliver a buried services corridor designed to carry gas, water, optical fibre, hydrogen and other utilities critical to the Northern Territory’s future.
This project is now in feasibility stage, which will include further detailed technical and commercial feasibility assessments, as well as consulting with land owners and other key stakeholders about the proposed alignment.
The significance of the Beetaloo Sub-basin’s potential is recognised by the Australian Government through the Beetaloo Strategic Basin Plan, the first of five plans to be delivered under the Strategic Basin Plans Program.
The Australian Governments National Gas Infrastructure Plan also emphasises the importance of the Beetaloo in meeting the projected shortfalls in the east coast gas market over the next 20 years.
By working together with the Australian Government, gas operators, and local and Aboriginal communities, the Northern Territory Government can unlock the Beetaloo Sub-basin’s enormous potential and realise thousands of jobs and significant economic growth for Territorians over the next 40 years or more.
