Assessment
Queensland (DSEWPC, 2011). While the clearing and maintenance of access tracks could increase the movement of feral predators in the region, these risks will be mitigated through measures outlined in the EMP.
Unlikely
There is no direct evidence that disease has contributed to population declines in northern quolls (Hill and Ward, 2016). The Project is expected to have minimal potential to introduce or amplify disease transmission within the local quoll population. As such, the Project is unlikely to introduce disease that may cause the species to decline. While approximately 19.95 hectares of potential foraging habitat will be removed, similar quality habitat remains widely available throughout the region. No potential breeding or denning sites will be affected as no suitable ones were identified. The Project will not significantly impact local habitat connectivity or cause habitat fragmentation. Indirect impacts from construction and operation will be minimised through the implementation of mitigation measures outlined in the EMP

Wulguru Technical Services Pty Ltd – Heritage Minerals Upper Mundic Gully TSF – Fauna Survey Assessment Report 58 A population survey was conducted for Grevillea hockingsii . The survey involved transversing all areas within in G. hockingsii was confirmed. In total 67 individuals of G. hockingsii were confirmed within the project area during field surveys. Individuals ranged from seedlings to mature flowering/seeding individuals. All individuals appeared of good health. In addition to the above population, approximately 24.30 ha of essential habitat, and an additional 5.20 ha of suitable habitat, has been mapped for the species within the project area. Suitable habitat for the species, within the project area, has been describe as low woodland to open forests dominated by Corymbia citriodora , Corymbia trachyphloia , Syncarpia glomulifera and/or Acacia spp, on steep slopes and hill crests with shallow, well drained, sandy loam soils derived from sandstone or basalt volcanic rocks. Dumping of mine waste by previous site operators has resulted in land contamination across most of the Mount Morgan Mine. Contaminated runoff and seepage from existing mine infrastructure are actively contributing to land contamination. Prior to mining activities occurring at the Mount Morgan Mine, the headwater of the Mundic Gully flowed north to south before flowing in an easterly direction towards the Dee River. What should be the 4.8. Grevillea hockingsii Grevillea hockingsii only occurs in Queensland, where it is known from three disjunct areas: Coominglah State Forest west of Monto with 21 occurrences in AVH (2025), then Callide Timber Reserve northeast of Biloela with 11 occurrences in AVH (2025) and surrounding and within Mount Morgan with four occurrences in AVH (2025). The specimens collected near Mount Morgan ranged from 1984-2001 and were collected on Razor Back Range 3 km west of Mount Morgan. The species is typically found on slopes in hilly sandstone country on shallow sandy to sandy loam soils which are light brown to red in colour and occasionally stony or gravelly. It grows in woodland or open forest communities typically dominated by Eucalyptus decorticans , Corymbia citriodora subsp. variegata , Eucalyptus suffulgens or Eucalyptus acmenoides (DETSI 2025). The species has occasionally been described on the edge of soaks.
