Perhaps, but I have limited access to images of an O. oreades female to compare this specimen with. O. oreades is not included in the Moths of Victoria visual key to the Oxycanus (genus). Moths of Victoria (Part 6 supporting disc) shows a pinned specimen of O, oreades female (Edwards and Green, 2011) from high alpine Mt Twynam in Kosciuszko National Park (NSW), but that specimen shows fully extended, light coloured tapered forewings and somewhat shorter antennae. Of the females in the Moths of Victoria key I would say the antennae look most like an O. australis female.
