Geographical variation to some extent clinal, and all three mainland races appear to intergrade; absence from Bass Strait islands suggests that Tasmanian race leachi may now be isolated. Other proposed races include ferdinandi (WC Australia, also Great Victoria Desert), which apparently relates to intergrading populations; sandlandi (coastal SC & SE Australia) and addenda (NW Victoria), both considered synonyms of leighi; and pallida (arid parts of Western Australia) and multi (humid SW Western Australia), both synonymized with nominate. Four subspecies recognized.
