A female Abantiades sp, (genus) I think, The antennae a small and thin and the wing markings faint and abbreviated ansd moth is large in size - but this family is notorious for variations in colour and wing patterns within species. I have initially suggested A. labryinthicus considering likelihood and the Abantiades genus known distributions ( see Simonsen T.J 1918 CSIRO) , but A. magnficus is also a possibility. see also: https://biocache.ala.org.au/occurrences/3192f93e-bb60-46c3-99e7-aebf0b43b718
A third species that has similar females is Abantiades latipennis. Males were seen in numbers at 1200m in the ranges further west earlier in the week. And also female Abantiades atripalpis inn April/May
