Acacia grandifolia is a tree growing to about 8 m high with flowers in long golden spikes (Orchard & Wilson 2001a).

This species is endemic to south-east Qld and is restricted to a small area around Gayndah, Mundubbera, Coulston Lakes and Proston in the Burnett District (Qld CRA/RFA Steering Committee 1998; QDNR 2000).

The type specimen is from 54 km south of Mundubbera and another specimen is from 12 km east of Gayndah (Pedley 1987). The species occurs in SF 132 (Brovinia), SF 220 (Malmaison), SF 249 (Wigton), SF 255 (Woroon), SF 1344 (Boompa) (QDNR 2000). Also in SF 210 and on Brian Pastures Research Station. It is also recorded from leasehold land and road verges in the area (Qld CRA/RFA Steering Committee 1998).

The literature does not specify how many populations exist, though its existence near three towns and in five state forests (QDNR 2000), suggests around eight populations. The species occurs as large colonies or as scattered individuals (QDNR 2000). It covers a range of approx. 100 km and encompasses an area of occurrence of approx. 4200 sq. km. (Qld CRA/RFA Steering Committee 1998).

There are no records of this species from a conservation reserve or a protected area (Briggs & Leigh 1996; Qld CRA/RFA Steering Committee 1998; QDNR 2000).

The species grows on hilly terrain of varying aspects and slope, on hillcrests, in gullies on plains (Qld CRA/RFA Steering Committee 1998). The species appears to flourish in disturbed ground and grows well on roadsides. At the type locality the species forms open stands on sand, among large sandstone boulders. It has also been recorded on shallow stony soils derived from basalt (Pedley 1978, 1987; Orchard & Wilson 2001a).

It occurs in ironbark gum and spotted gum forests and woodlands (QDNR 2000). The most frequently recorded associated tree species are Eucalyptus crebra, Corymbia citriodora, C. trachyphloia and E. exserta (Qld CRA/RFA Steering Committee 1998).

This species flowers from July to Oct. (Pedley 1978, 1987; Qld CRA/RFA Steering Committee 1998; Orchard & Wilson 2001a). Mature pods have been collected from Oct. to Nov. (Pedley 1978, 1987; Qld CRA/RFA Steering Committee 1998). Seeds are dormant when released from mature pods and accumulate as a persistent seed bank between fires. It is not known how long seeds remain viable in the soil (Qld CRA/RFA Steering Committee 1998).

Although plants flowered profusely, no seed was produced at observed sites over two successive years. This may have been due to climatic conditions or to low genetic diversity. Although not confirmed, it is suspected that these plants usually seed irregularly (Leverington et al. 2003).

Rare species occurring within a restricted geographical location typically exhibit low levels of genetic diversity; this is so for A. grandifolia. Its genetic profile suggests that it may have been geographically isolated from near relatives and has developed in isolation (Leverington et al. 2003).

The plant appears to respond well to disturbance, with records of good regeneration in disturbed areas and by roadsides. It appears to be highly fire tolerant with populations expanding after fire (Leverington et al. 2003).

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.
