Subspecies argenteus and colletti sometimes treated as a separate species. Subspecies colletti often included within argenteus, but seems reasonably distinctive. Nominate subspecies intergrades with leucopterus on western slopes of Great Dividing Range from southern Queensland south to Otway Range, in Victoria.
Proposed subspecies latens (Uwins I, in northern Western Australia) is a synonym of argenteus.
The following 5 subspecies are recognised:
torquatus (Latham, 1801) - Coastal south-eastern Queensland south (mainly east and south of Great Dividing Range) to Victoria.
.
argenteus Gould, 1841 - Western Australia (Kimberley region east from Yampi Sound and mouth of Fitzroy R) and marginally north-western northern Territory (east to mouth of Victoria R), south to Great Sandy Desert. Considered by some to be a subspecies of Grey Butcherbird (Cracticus torquatus) (argenteus). Considered by some authors to be a distinct species, Silver-backed Butcherbird (Cracticus argenteus).
colletti Mathews, 1912 - Coastal northern Territory from Victoria R almost to eastern tip of Arnhem Land, south to northern Tanami Desert in the west. Considered by some to be a subspecies of Silver-backed Butcherbird (Cracticus argenteus) (colletti). Considered by some authors to be a subspecies of Silver-backed Butcherbird (Cracticus argenteus).
leucopterus Gould, 1848 - Southern half of Australia south of 20° southern (except for desert areas of western Australia, South Australia, northern Territory and western half of Queensland), in east extending north in eastern Queensland (west of Great Dividing Range) towards southern Cape York Peninsula.
cinereus (Gould, 1837) - Tasmania.
