Generally uncommon to rare and sporadically distributed in coastal and near-coastal areas; growing in heathy forest in freely draining, sandy soil; less commonly in adjacent ranges among shrubs in gravelly loam; also in sparse open forest in clay loam. R.D. Fitzgerald, who described the species, records it around Sydney as ‘growing in swampy ground under the shade of tea-trees (Kunzea)'.
