One of the sp with pink body and hindwings. Hard to tell more with such worn wings. Yes she was probably laying which they do on the wing if not so worn.
Hi blacksheep, thanks for your sighting. The media you provided is missing or unclear. To help us verify this sighting, please provide additional media.
Not sure which named Fraus (genus) species would best fit. Perhaps Fraus marginospina although that species seems to be a dry country species (eg. SA, western Victoria) https://www.inaturalist.org/taxa/522870-Fraus-marginispina F. orientalis (Eastern Fraus) has a more eastern range better suiting where this record was made. https://www.inaturalist.org/taxa/1072359-Fraus-orientalis There is brown stripiing which would correspond roughly to F. orientalis.
