I agree it is Endoxyla sp. There is a sequence on iNat of a newly emerged E. lituratus which does show the white 'tummy' with the upper side of the abdomen black and white cross-ways stripes. https://inaturalist.ala.org.au/observations/191350527 Images on http://lepidoptera.butterflyhouse.com.au/coss/coss-under.html show various with white on the underside of the abdomen
This is just one moth, newly emerged I think. The second image is it's abdomen, which can also be seen with third image. Could not get a picture of its head, unfortunately
I'm not sure about the second image. I assume it.s one moth seen from below with a bloated abdomen. Distinct serrated edge to the white colouring where it meets the black. For example:- https://www.inaturalist.org/observations/64087792
