There area few images of a species Chlenias stenosticha for which some specimens show black blotches like those of this specimen but they appear to be in different places on the forewing. See

This is a Calathusa species. (The palpi indicate Noctuidae or Erebidae.) There are many species, including undescribed ones, and some are quite variable. I'm not sure if it will be possible to isolate the species of this one.

I meant to add that similar dots occur within the variation of more than one of the species. C. thermochroa is certainly a common prospect, but it has a transverse rather than longitudinal pattern, and is usually variable brown rather than grey moth (although there are grey exceptions. I think C. thermosticha, a widespread inland moth, is the most likely prospect..

4247141 and 4245724 seem to be the same species. They match a few specimens from the NSW tablelands and further west that might be a variation on Calathusa thermosticha, or a similar unnamed species.
