Specimen has the finely attenuated antennae said to be a feature of many Garrha spp. (Zborowski and Edwards 2017). Looks close to G. ocellifera although seems to have darker markings which are continuous between the wings and thorax which is not seen on almost all the specimens of G. ocellifera I've seen online. Although see the specimen labelled Garrha sp, on the ALA https://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:cda0a9d9-e031-4c9c-a6f6-227d28d447c1#gallery
Yes, seems to match the specimen labelled G. iodesema on the ALA: https://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:a8b54d4a-70b9-458a-80f4-79109fc46226
