I suggest A. triganophora based on several images of Donald Hobern's (Black Mountain) on the ALA website: http://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:591a07ae-9d34-4c28-b4ce-f9b45a3d3521#gallery. I think also one or two images previously called Amata sp.on CNM are a close match. However, I stand to be corrected back to Amata sp.!
