I wasn't sure. Moth has large abdomen. I wondered whether it was Heliozela (genus) or Heliothela (genus) eg. H. floricola. Fore example:- https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/429141ef-999d-4186-90f5-35351138e8f8#gallery
With difficulty. Heliozela seems no likely due to colour and shape, To me the large protruding abdomen suggests Heliothela (genus). There is no hint of yellow hindwing, so two out of the three names species online ie H. atterima and H. floricola could qualify, See here:- https://bold-au.hobern.net/taxon.php?taxid=102453
