I'm not certain whether it's Epidesmia chilonaria or hypenaria. The palpi of hypenaria are longer, but the photos don't show the length explicitly. The strongly white costa suggests chilonaria, but I think it's variable in both species.
There seems no evidence of a bright white costa in any of the 21 specimens of Epidesmia hypenaria in the BOLD page http://v4.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=89567 only pale brown or orangish.
The moths are wonderfully camouflaged and rest on the ground on dried leaves etc. Their caterpillars are brown and resemble twigs and feed on the leaves of eucalypts and bottlebrushes (both species within meters of where the moth was found).
