value of potential habitat, this species is considered unlikely to occur within the project area. Unlikely to occur Vegetation types preferred by this species were not identified within the project area. While Upper Mundic Gully Dam may provide potentially suitable foraging habitat, given its seasonal inundation and the likely presence of amphibian prey species, the surrounding Regional Ecosystem (RE) type is classified as 11.12.6, which does not occur on cracking clay soils typically associated with optimal habitat for the species. Species was not detected during active surveys conducted throughout the project area. Due to the low dispersal rate of this species and lack of historical records, this species is considered unlikely to occur within the project area. Unlikely to occur Marginally suitable habitat in the form of moist areas adjacent to lake margins that support frog populations occurs around Upper Mundic Gully dam. Active surveys undertaken across the project area yielded no detections of the species or evidence of habitat utilisation. The nearest record occurs 35 km southwest of the Project (DETSI, 2025). Due to the low dispersal rate of this species and lack of historical records, this species is considered unlikely to occur within the project area. species is considered to have the potential to occur within the project area.

Suitable hunting habitat occurs in the northern area of the project area.

In Queensland, the grey snake ( Hemiaspis damelii ) is primarily associated with Brigalow ( Acacia harpophylla ) and Belah ( Casuarina cristata ) woodlands occurring on heavy cracking clay soils, particularly in proximity to watercourses, gullies, floodplains, and ephemeral wetlands. The Mitchell grass ( Astrebla spp. ) grasslands on alluvial plains with similar soil profiles. Critical habitat attributes include seasonally inundated landscapes, heavy-textured soils, and the availability of amphibian prey species, which constitute the primary diet (DCCEEW, 2025a). The preferred habitat is within, or adjacent to, habitat that is favoured by frogs. The species is known to prefer woodlands and open forests associated with moist areas, particularly gilgai mounds and depressions in REs on landzone 4, but also lake margins and wetlands (DoE, 2014a). species also inhabits Queensland bluegrass ( Dichanthium spp. ) and
