Acacia gordonii is an erect or spreading, often straggly heath-like shrub. It grows to 1.5 m high, sometimes to 2 m, and has perfumed globular golden yellow flower heads (Harden 1991; Orchard & Wilson 2001).

The species is restricted to the Central Coast region of NSW (Harden 2002; NSW NPWS 2003g). Chiefly found in the lower eastern slopes of the Blue Mts (Orchard & Wilson 2001), it also grows in the Glenorie-Maroota area on the northern outskirts of Sydney (Benson & McDougall 1996; Fairley & Moore 2000) and there is a record from Hornsby (Tindale 1968; Simmons 1982; Orchard & Wilson 2001). Specific localities at which this species has been recorded include: Linden, Kings Tableland, Bilpin and Faulconbridge (Tindale 1968; Harden 1991, 2002; Benson & McDougall 1996; Fairley & Moore 2000; Orchard & Wilson 2001). Local government areas in which it is found include: Baulkham Hills, Blue Mts, Hawkesbury, Hornsby and Sydney (NSW NPWS 1999ak).

The species is conserved within Blue Mts NP (Benson & McDougall 1996) and Maroota NP (Glenorie & Forest Glen) (James 1997).

This species grows in dry sclerophyll open forest, woodland and heath on sandy soil amongst sandstone outcrops (Simmons 1982; Harden 1991; Tame 1992; Benson & McDougall 1996; James 1997; NSW NPWS 1999ak; Fairley & Moore 2000; Orchard & Wilson 2001). It occurs on rock platforms on ridgetops and spurs at 0-400 m asl. The substrate is Hawkesbury Sandstone with some residual clay and laterite influence, low in nutrients and well drained. The average annual rainfall is 900-1000 mm. Associated species include Eucalyptus eximia, E. gummifera, E. squamea and E. piperita (Benson & McDougall 1996).

The flowers are borne Aug.-Sept. and pods occur Oct.-Feb. (Simmons 1982; Harden 1991; Tame 1992; Benson & McDougall 1996; Fairley & Moore 2000; Orchard & Wilson 2001).

The species resprouts and germinates prolifically after high intensity fires (S. Douglas, pers. comm. in Benson & McDougall 1996).

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.
