Hi Wendy, I'm not sure I can easily agree this is C. melanaleuca and not L. comparella. For example, if we go to iNaturalist page you cite above which iare sightings classified as C. melenaleuca ie.:- https://inaturalist.ala.org.au/observations?verifiable=true&taxon_id=701043&place_id=6744&preferred_place_id=6744 to my eye there looks to be a sighting amongst them which to my eye is likely C. comparella ie. https://inaturalist.ala.org.au/observations/257422504 amongst the majority which are most likely C. melenaleuca eg. https://inaturalist.ala.org.au/observations/246421001
I have more faith in BOLD images than iNaturalist, as their classifications are based on DNA rather than wing pattern. I think this looks more like https://v4.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=89480 than https://v4.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=364899 which has a partial black line along the forewing inner margin.
