Gomeroi Traditional Owners will meet this weekend to decide whether to accept or reject Santos' latest proposal for the Narrabri Lateral Pipeline.

The proposal forms part of an Indigenous Land Use Agreement covering state forest and stock routes across the Pilliga Forest and Liverpool Plains.

Gomeroi Elder, Aunty Polly Cutmore, said the offer repeats terms the claimant group previously rejected.

"Our mob rejected Santos' offer before and they have not come up with anything new apart from this ILUA, which attempts to guarantee access to lands we already have access to," she said.

She said the company had not provided the cultural evidence Traditional Owners had requested.

"Santos have spent 12 years undertaking studies in the forest, yet have not undertaken any credible study of the stories and cultural knowledge and the importance of the forest as a whole to Gomeroi people," she said.

Aunty Polly said the offer cannot address the impacts already determined through the planning process.

"A commitment now is too late as it will be outside the planning approval process," she said.

She said Gomeroi people should continue to reject the proposal.

"Gomeroi Traditional Owners should reject this agreement and any other inducements to get Gomeroi to renege on their promise to their people to protect the country and waters of the Great Artesian Basin, special to all Gomeroi people," Aunty Polly said.

The Native Title Claimant Group will vote on the ILUA in Tamworth.

The decision comes while the group continues its appeal against the National Native Title Tribunal ruling which gave Santos permission to proceed with petroleum production leases for the Narrabri Gas Project.

The Federal Court hearing has been delayed until March 2026.

In November, Gomeroi opponents of the plan rallied in Magandjin (Brisbane), with the action to coincide with the beginning of the appeal hearing. The gathering went ahead despite the adjournment of the hearing until March.

Gomeroi man, Boe Spearim, said the goal was to maintain public support and detailed the irreversible effects the project will have on Country.

"The main thing about today is just to continue to garner that support for Gomeroi folks with our struggle against Santos," he said at the rally.

"The irreversible effects that they [will] have on Country, whether that's destroying sacred sites, where there's grooving stones, to actual cave paintings, to scarred trees, to campsites.

"They want to put the gas wells above the Great Artesian Basin, which could possibly pollute the Great Artesian Basin."

Traditional Owners say the outcome of this weekend's meeting will shape the next stage of their resistance to the Narrabri Gas Project and the pipeline proposal.
