South of Brisbane, the species is recorded along the Nerang River and the Tallebudgera valleys and has an important stronghold in the national parks adjacent to the Queensland-New South Wales border. In New South Wales, the species is widespread in rainforest southwards to the Blackwall Range near Wardell and the Cherry Tree State Forest near Mallangangee (Braby 2000, Sands & New 2002, Sands & Scott 1997). Note that although the species may be abundant at altitude (e.g. the Queensland-New South Wales border ranges national parks), these populations typically die out due to cold winter temperatures and require migration of adults from the lowlands for persistence. Population sizes in these habitats therefore vary from year to year.
