I immediately thought Fraus but was not happy with any of the sp for matching the wing pattern. The specimens on Don's site do not have white spots like the above moth has. Also Kallies, A. et al in Moths of Victoria Part 6 CD p2/2 for that sp say it used to be found widely in eastern Victoria now mainly in the Alps above 1400m. Also if it is bigger than male Elhamma australasiae it way too big for any of the Fraus sp. I have been considering Oncopera rufobrunnea https://inaturalist.ala.org.au/observations?place_id=6744&quality_grade=research&taxon_id=892233
Yes, good suggestion, several O. rufobrunnea specimens a similar dot pattern. The difficulty here is the angle of the shots and the expected underlying mottled pattern is not obvious.
