I'm wondering whether A eximia (Forest Ghost moth) is not the more likely ID given its strongly south eastern distribution evident on the ALA and on LBH and these images which show specimens with the two isolated black dots with white centres, presumably the female also. see here;- https://biocache.ala.org.au/occurrences/61a7e442-eed7-40ea-9249-1e01170d45ec https://biocache.ala.org.au/occurrences/a3d76c87-cadd-4330-9825-523872ee7d88 A. blackburni apparently (on ALA map evidence) has a more 'dry country' distribution ie western Victoria and in South Australia.
