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.

Yes, good suggestion, several O. rufobrunnea specimens a similar dot pattern. The difficulty here is the angle of the shots and the expected underlying mottled pattern is not obvious.
