I am suggesting this is similar to Moths of Victoria's 'Proteuxoa sp. (24)', see Part (9), a species which has been recorded on Black Mt. by I. Common (1956) and also occurs in Victoria. It has a prominent white coloured major lobe to the renifom mark which stands out and two white orbicular marks between the reniform mark and the thorax. There is another similar looking 'Proteuxoa sp.(11)' but MoV have recorded that species from dry western Victoria.
