Environmental experts say they are "deeply concerned" by a recent contamination incident in the Northern Territory's Beetaloo Basin and have warned it could be the start of more to come should full-scale fracking go ahead in the region.

Traditional Owners, doctors and scientists have joined environment and human rights organisations in signing a letter calling on APA Group to end its plans to build a pipeline enabling gas fracking in the Northern Territory.

Native title holders say they are insulted by the NT government's decision to approve a plan to drill nine new gas wells in the Beetaloo Basin before they've decided whether to support the project.

A controversial gas project in the heart of the Northern Territory has been given the green light by the government.

Nurrdalinji Aboriginal Corporation, which represents native title holders from the NT's Beetaloo Basin who wish to protect Country, have responded to the draft Territory Co-ordinator Bill released Thursday, which they say is "designed to side-step environmental and other laws that apply to fracking".

Environment Minister Tanya Plibersek will force controversial gas fracking projects in Australia’s far north to undergo tough environmental checks, as the federal government brawls with political opponents and miners over its nature law reforms.

The newly elected Northern Territory government wants to grant itself sweeping new powers to exempt major projects from environmental assessments in a move described by conservationists and Indigenous groups as authoritarian and anti-democratic.
