Proposed subspecies ellioti (from Watson River, in northern Queensland) is based on an intergrade between nominate and monachus; clamans, described from Wallaroo Gorge (Carnarvon Range, in south-eastern Queensland), is synonymized with monachus.
The following 3 subspecies are recognised:
corniculatus (Latham, 1790) - Southern New Guinea (Wassi Kussa R east to Oriomo R) and north-eastern Australia (north-eastern Queensland from about Weipa-Iron Range south, extending inland to middle reaches of Mitchell R and Staaten R and upper Norman R, to Mackay).
monachus (Latham, 1801) - Eastern and south-eastern Australia from central-eastern Queensland (Mackay region) south, extending inland to c. 144-145° east, to central-southern Victoria (Gippsland).
ellioti Mathews, 1912 - Trans-Fly lowlands of south-eastern New Guinea.
