The revised Great Artesian Basin Jurassic-Cretaceous boundary was produced by the Great Artesian Basin Water Resource Assessment (GABWRA) . This boundary is modified from that of Habermehl and Lau 1997 and incorporates the revised boundary from the South Australia Great Artesian Basin (Eromanga Basin) Hydrogeological map 2012. Modifications made to sections of this boundary as part of the GABWRA include major revisions to the Surat and Clarence-Moreton Basins boundary; southern part of the Coonamble Embayment; NW Queensland boundary within the Lawn Hill and Westmoreland 1:250K map sheet areas. The dataset includes boundaries of basement inliers within the GAB Note: Habermehl and Lau 1997 boundary included Triassic GAB formations in Queensland which were not considered by the GABWRA. Data is available in polygon format. REFERENCE: Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.
