Restricted in Victoria to rocky areas around Mt Arapiles and apparently the northern parts of the Grampians (but latter localities not represented in MEL). Seedlings have been reported from near at least one planting elsewhere in the state (Wonga Park).
Acacia ulicifolia has somewhat similar phyllodes and heads but it is a non-resinous shrub with 5-merous flowers and non-arillate seeds. Acacia oxycedrus has similar phyllodes except that they are multiveined, and it has spicate inflorescences.
