I agree the sticks are more densely attached to the case than is normal for M. elongatus. The only other Australian Metura species, M. phyllosacca is inclined to cover its case with dead leaves, so that is no contender. However, a drawing by John Westwood in 1854 shows the case of Lomera boisduvalii with sticks attached like this specimen, and this species has been found in Victoria and NSW, so I suspect this specimen is L. boisdualii. It would be wonderful if you could rear it in captivity to get an adult moth for confirmation (or refutation).
