Cullen australasicum can generally be distinguished in the field by its upright branched habit and pinkish flowers. In herbarium material it can be extremely difficult to distinguish it from C. pallidum, C. patens and C. discolor.
An almost entirely glabrous plant collected near Mildura may be referable to this species.
