McNutt's Wattle is a tall bushy shrub or tree 1-3 m high with golden yellow, globular flower heads (Harden 1991; Tame 1992; Steenbeeke 1998; Orchard & Wilson 2001a).

The species is found in the Glen Innes - Tenterfield district in the Northern Tablelands of NSW (Tame 1992; Orchard & Wilson 2001) in an area approximately bounded by Ashford, Deepwater and Boonoo Boonoo NP (Harden 1991; Quinn et al. 1995; J.T.Hunter 2000, pers. comm.; Orchard & Wilson 2001).

The species is most common in the Boonoo Boonoo Falls area (Harden 1991; Sheringham & Westaway 1995; Hunter & Clarke 1998) and the Torrington district (Sheringham & Westaway 1995; Hunter & Clarke 1998; J.T.Hunter 2000, pers. comm.). It is conserved in Boonoo Boonoo NP, with fewer than 1000 individuals (Sheringham & Westaway 1995; Briggs & Leigh 1996) and in the Torrington State Recreation Area, where at least 1000 plants occur in several populations (Copeland & Hunter 1999). In addition, a small population was recently discovered along Morven Creek in the western additions to Washpool NP (J.Hunter 1998 in Copeland & Hunter 1999).

This species favours sandy soils on acid granite substrates, often among boulders, in riparian situations near streams and in gorges (Harden 1991; Tame 1992; Sheringham & Westaway 1995; Orchard & Wilson 2001). It occurs in dry sclerophyll forest, woodland and heath (Harden 1991; Tame 1992; Sheringham & Westaway 1995; Steenbeeke 1998). Found at 500-1000 m asl (Quinn et al. 1995).

Associated species include Allocasuarina littoralis, Angophora floribunda, Bursaria spinosa, Callistemon flavovirens, Eucalyptus biturbinata, Leptospermum brachyandra, Lophostemon confertus and Pomaderris sp. (Quinn et al. 1995; Sheringham & Westaway 1995).

A comprehensive description of the community types that A. macnuttiana occurs in, including associated vegetation, geology, conservation status, and habitat threats, can be found in Hunter & Clark (1998).

Flowers are borne July-Sept (Harden 1991). Fruit are borne spring to summer (Steenbeeke 1998).

It is a relatively short-lived obligate seeder that requires a comparatively large population size to maintain its viability (Copeland & Hunter 1999), As with most acacias, this species would be expected to regenerate from seed after fire (Quinn et al. 1995).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
