in NM ??? This is the first/only record on NM. For distribution maps see the map here https://bold-au.hobern.net/specimens.php?taxid=366689 and here (map button below pictures) https://inaturalist.ala.org.au/taxa/555454-Macrobathra-sarcoleuca
Both distribution maps indicate M. sarcolueca has somewhat of an Australia wide northerm distribution, but show no records from SE Australia. Until recently the stonghold of representation NatutreMapr has been predominently SE Australia, so personally, I'm not surprised such a distinctive moth has not showed up until now.
