I suggested G. oculata because on the forewing near the trailing edge I didn't think there was a 'pale tapering sub-marginal band" as there is for G. oculicola, see http://lepidoptera.butterflyhouse.com.au/cato/oculata.html However, I stand to be corrected on that....
In the drawing by Snellen (the author of of Grammodes oculata) of this species, there is no pale submarginal arc, see fig 6 in https://www.biodiversitylibrary.org/item/40933#page/301/mode/1up Meanwhile Walker, author of Grammodes oculicola, says "a testaceous streak along the exterior border", see https://www.biodiversitylibrary.org/item/121628#page/482/mode/1up. This specimen, 4251430, has a testaceous streak along the exterior border, so I think it is Grammodes oculicola.
