Barea phoenochyta ? looks to have bigger white spots like above, also more local https://bold-au.hobern.net/specimens.php?taxid=415151 https://www.inaturalist.org/observations?place_id=6744&taxon_id=924350 B. periodica https://bold-au.hobern.net/specimens.php?taxid=415183
Difficult ID because several named Barea spp. show this alternating black and white bar pattern in their forewings to some extent, I considered B. phoenochyta but which to me seems to have three white spots in-line whereas I thought B periodica apparently has only two prominent white spots in-line as in this specimen.
I got a moth rather like this last night. Mine, photographed from behind has a white spot on the thorax, not obvious on the above moth. I will see what iNat thinks, for another opinion. see https://www.inaturalist.org/observations/328281866
OK, I think your moth looks very like this one, but I don't find the single Holbern B. phoenochyta photo to be a convincing match to either, but I could be wrong. It will be interesting to see what the experts on iNaturalists say to your suggested ID,
A new comment on iNat on this - not a solution yet https://inaturalist.ala.org.au/observations/328281866 Mimobrachyoma maculifera - has more white on 'shoulders/neck' https://bold-au.hobern.net/specimens.php?taxid=415676
