I think this moth is Mixochroa sp. ANIC1. M. gratiosata has a distinct white line across the wing, not dots like above. Also the BOLD (Hobern) specimens are all from Tasmania, likewise iNat. Mixochroa sp. ANIC1 has the row of dots and the BOLD (Hobern) specimens are from around Canberra. https://bold-au.hobern.net/taxon.php?taxid=363280 https://inaturalist.ala.org.au/observations?place_id=6744&quality_grade=research&taxon_id=965133 These comments are relevant to the 3 specimens of 'M. gratiosata' from Canberra area already on NM.
