It is endemic to Australia, where it is native to New South Wales and Tasmania,[5] with one subspecies introduced in Victoria.[6] It is considered vulnerable and faces a number of threats including land clearing, habitat degradation, and damage from or competition with invasive species.[7]

There are three subspecies currently recognised:[7]
- C. o. oblonga – northeast Tasmania,[7] introduced in Victoria[6]
- C. o. corangensis (K.D. Hill) – New England Tablelands in northern New South Wales[7]
- C. o. parva (K.D. Hill) – Corang River catchment in southern New South Wales[7]
