Isa GBA Region

Isa GBA Region

The Isa GBA region covers approximately 8,223 square kilometers and is centred on the remote township of Doomadgee in north-west Queensland. The area is specifically defined for the GBA Program as the area that contains known unconventional hydrocarbon systems (shale gas) hosted in rocks of the Isa Superbasin. It is also the most likely area of the Isa Superbasin where future development of unconventional hydrocarbon resources (shale gas) could result in delivery of gas to the East Coast Gas Market.

Rapid regional prioritisation (stage 1)

On 18 January 2018 the Isa GBA region was announced as the second basin selected for assessment under the Geological and Bioregional Assessment Program. The selection was based on the region’s world class petroleum source rocks, demonstrated shale gas flows, and proximity to pipeline infrastructure. These features make it a candidate to deliver new gas supplies to the East Coast Gas Market. The rapid regional prioritisation report can be found here. 

Baseline analysis (stage 2)

The geological and environmental baseline assessment for the Isa GBA region synthesises knowledge about the geology and prospectivity of shale gas resources, water resources, protected matters and risks to water and the environment.

User panels

The next meeting of the Isa GBA region user panel is expected to be held in the second half of 2020.

Previous user panel meetings were held on 9 May 2018 and 13 August 2019.

Discussions from each user panel meeting are summarised in a communique which is published on the Geological and Bioregional Assessment website (below).
