Dark filaments on the male antennae apparently not as pronounced in this speciemen as in most A. ferriginosa photographed elsewhere. Perhaps amother species?
The females figured in Moths of Victoria Part 1 2nd ed CD pages show females with the white/pale antennae with short pectinations. Also some shots on iNat e.g. https://inaturalist.ala.org.au/observations/200749846 https://inaturalist.ala.org.au/observations?place_id=6744&preferred_place_id=6744&quality_grade=research&taxon_id=471402
