This species was previously known as Centaurium spicatum or Centaurium australe . Distribution and Habitat This species is found throughout Australia and in New Caledonia. In Tasmania, Schenkia australis has been recorded from cleared forest pasture, rainforest/wet sclerophyll forest and heathland in the east and north of the State (Curtis 1963). This species may have been introduced to Tasmania.
