Variations
Two subspecies are generally recognized, *D. n. novaeguineae* (eastern Australia) and *D. n. minor* (Cape York Peninsula), with the latter being slightly smaller.

Conservation
Threats
Habitat loss and degradation (particularly loss of mature trees with hollows), Secondary poisoning (from pesticides or rodenticides), Competition with introduced species (e.g., Common Myna), Road mortality
Protection Programs
Habitat preservation and restoration initiatives, Public awareness campaigns promoting responsible pesticide use
Local National Laws
Protected under state and national legislation in Australia (e.g., National Parks and Wildlife Act).
