On this basis I suggest this sighting is C. filata not P. testulata.

Pasiphilodes testulata

For notes identifying features separating Chloroclystis filata, and Chloroclystis pallidiplaga/Pasiiphodes testulata see pp. 196-7 of 'Moths in the ACT' (Cocking et al (2022). ie.: "C. filata 'is very common and can be recognised by the dark inside the apex of the forewing, and in some specimens there is also a white patch extending inwards from near the inner margin (see arrows on photos p. 196). Chloroclystis pallidiplaga (or Pasidiphilodes [Chloroclystis] testulata, a very similar species) usually has two distinctive white patches on the forewing in different positions from the white patch that can occur on C, filata." (These different white patch positions are illustrated on pp. 196 and 197 for the two different species).
