==Distribution and habitat== Tasmanian smokebush usually grows in coastal heathland and heathy forest or woodland between Bruny Island and Cape Barren Island with a disjunct population near Avoca in the Fingal Valley.

==Conservation status== Tasmanian smokebush is listed as "vulnerable" under the Australian Government ''Environment Protection and Biodiversity Conservation Act 1999''. The main threats to the species are land clearance and fragmentation, the species' small population size, and dieback caused by ''Phytophthora cinnamomi''.<ref name="dcceew" />
