Confirmed present This species was recorded within the project area

Yes – Suitable habitat was identified across most of the project area. Suitable habitat presented as Eucalypt forests and/or woodlands on steep, rocky hillsides with skeletal to shallow sandy soils.

Yes – Three historical (2001) records are located within the project area, the nearest of which is ~0.18 km north west of the project area.

Grevillea hockingsii only occurs in Queensland, where it is known from three disjunct areas: Coominglah State Forest west of Monto, Callide Ra. east of Biloela, and Razor Back Ra. Near Mt Morgan (DETSI, 2025). The species is 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 (DETSI, 2025). Leichhardtia brevifolia occurs in north and central Queensland where it is known from near Townsville, Springsure and north of Rockhampton (DCCEEW, 2025). North of Rockhampton, L. brevifolia grows on serpentine rock outcrops or crumbly black soils derived from serpentine in eucalypt woodland, often with Eucalyptus fibrosa and Corymbia xanthope . Near Paluma, the species grows in woodland dominated by E. granitica and E. acmenoides on granite soils (DCCEEW, 2025). Polianthion minutiflorum is known from five areas in east Queensland from Redcliffe Vale, south to Kingaroy. The species occurs in forest and woodland on sandstone slopes and gullies with skeletal soil or deep soils next to deeply weathered laterite (DEWHA 2008b). A small shrub or tree growing up to 6 m tall with red flowers and fruit and stiff and leathery leaves that are green and glossy. S. bidwillii is endemic to QLD, occurring from Mackay to Tweed Heads (DAWE 2020). It commonly occurs in lowland rainforest but can also be found in open forest or woodland. S. bidwillii is commonly found in areas adjacent to temporary and permanent watercourses.

Leichhardtia brevifolia

Unlikely to occur The project area is located in the distribution where the species or its habitat may occur and field surveys confirmed the presence of suitable habitat within the project area. However, no historical records were identified within the desktop assessment and the species was not confirmed within the project area. Unlikely to occur The project area is located in the distribution where the species or its habitat is likely to occur and recent historical records persist in the surrounding landscape. However, only marginal habitat was confirmed within the project area and the species was not observed during field surveys.

Species may occur in project area

No – the nearest historical record is approximately 70.14 km south of the project area.

Yes – Suitable habitat was identified across most of the project area. Suitable habitat presented as Eucalypt forests and/or woodlands on steep, rocky hillsides with skeletal to shallow sandy soils. Yes – Marginal habitat was identified across most of the project area. Marginal habitat presented as Corymbia citriodora forests and/or woodlands on steep, rocky hillsides with skeletal to shallow sandy soils.
