I think both 3383984 and 3384044 are Faviera tritalis (Phycitinae), common in southern tablelands grasslands. The photos don't show all, but F. tritalis has a rounded forewing termen whereas C. leptogrammellus has a more pointed apex; C. leptogrammellus usually has white lines between the veins towards the termen of the forewing; and F, tritalis has a darker hindwing that can be seen in one of the photos.
