I am suggesting this is Dysbatus singularis (referring to the Moths of Victoria key) because: (1) the curved black line from the wingtip is present - but it doesn't reach the third outer transverse line in the forewing - it reaches the line in D. stenodesma; (2) the third outer transverse line has shallow curves with a point; and (3) there is an elongated spot present located against the second outer transverse line (in the key this spot is against the line in a male, while not touching the second line in the female in Dysbatus singularis) - this pale spot is absent in Dysbatus sp. and doesn't touch the second line in D. stenodesma.
