The internal rift emerged after Ms Uibo last week told the ABC Territory Labor supported "strictly regulated" fracking adhering to all recommendations from the Pepper Inquiry. However, MLAs Dheran Young, Manuel Brown, Yiwarr McGrath and Chansey Paech all told the ABC they personally oppose the practice. Mr Brown said "our ecosystem is too fragile for any stuff-ups". Mr Paech had confirmed his long-standing opposition to ABC Radio Alice Springs earlier this month.
Deputy Opposition Leader Ed Smelt, who did not respond to a request for comment, has previously said gas was needed as part of the energy transition.
The stand-off comes two years after Labor was comprehensively defeated at the NT election, having lost votes to both the right and left. It also coincides with the start of production: the first fracked gas from the Beetaloo Basin began feeding into the grid this month.
While in government, Labor initially imposed a moratorium on fracking in 2016 before allowing the industry to proceed in 2018 following the independent Pepper Inquiry.
