Worn. I'm confident this is Hypena (genus), although not 100% sure this is H. subvittalis cf. to H. masuaralis. I have suggested H. subvittalis based on similar ALA images.
See AFD: https://biodiversity.org.au/afd/taxa/Rhynchina_obliquarlis Hypena masurialis Guenée, 1854 is the junior synonym of Rhynchina obliquarlis Kollar's 1844. Kollar's holotype was lost for a period, during which the replacement name Hypena masurialis Guenée, 1854, was suggested. Subsequently the holotype was found, and so now the junior replacement name is no longer used. How one distinguishes the genus Rhynchina from Hypena, and R. obliquarlis from H. subvitalis and H. obacerralis is beyond me.
