This may be an unnamed species from the Scoparia (genus). It appears to be a good match to this moth of which there are several photos on the ALA by Reiner Richter, see here:- https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/3fb7a124-1ad4-4213-bb53-ab46b983cf8c#gallery Further searching on Bold Systems may match it to an unnamed or named species held by ANIC. A good photo an an apparent first for CNM.
A further search has found a good match for S. gethosyna, previously recorded by D. Hobern at Aranda in October 2010.
