After more than a decade of drilling, permitting, political argument and Capital raising, the Beetaloo Basin has finally sold gas. Tamboran Resources (ASX:TBN) began commissioning its Shenandoah South project in the Northern Territory in early September and has now started delivering gas under a long-term contract with the Territory government. For a company that has spent its listed life as a pre-revenue explorer, the shift is fundamental. Tamboran is now a producer, in a market that badly needs new supply.

The latest development

Tamboran announced on 1 September 2026 that gas from the five Shenandoah South pad wells had begun flowing into the Sturt Plateau Compression Facility. First commercial sales to the Northern Territory government followed over the weekend of 5 to 6 September.

Gas flows are expected to increase to the full 40 terajoules a day contracted to the Territory government by early 2027. The gas comes from Shenandoah South near Daly Waters, which Tamboran holds jointly with Daly Waters Energy.

What investors may watch next

The ramp to 40 terajoules a day and the transition off discounted commissioning pricing are the immediate operational milestones. Tamboran's FY2026 annual report, not released at the time of writing, will provide the first full picture of costs and cash following the Falcon Oil & Gas Acquisition completed in May 2026.

Investors will also look for an updated contingent resource statement, progress on securing an LNG joint venture partner, and further well results from the Beetaloo Central Development Area.

Conclusion

Tamboran has done the hardest thing an explorer can do, which is to become a producer. The question now is whether flow rates hold, whether costs come down as the company applies local sand and repeat well designs, and whether a credible partner emerges for the far larger LNG ambition. Those variables will determine whether first gas proves a milestone or a turning point.
