4 subspecies, 3 in Victoria.

Previous records of the species for East Gippsland are based on misdetermination of specimens, most of which are O. rugosa. Both these species have geographically disjunct subspecies with distinct leaf morphologies. 

Olearia asterotricha subsp. glaucophylla Messina occurs north of Mittagong in New South Wales. This subspecies is distinguished by its distinctly bluish leaves that are lobed in the distal half, and white ligules.
