Australia = New South Wales.
Generally considered to be closest to A. innotata, A. baeri and A. nyroca. Hybridization with Anas platyrhynchos recorded in captivity. Breeding birds collected in Banks Is, Vanuatu, were assigned a separate subspecies, extima, although it has been suggested that this population represented a temporary colonization by nomadic Australian birds; similarly, races have been described from Java (ledeboeri) and W New Guinea (papuana). Monotypic.
