Very unsure.
Tightly curled leaf on a Eucalyptus camaldulensis camaldulensis. When opened tiny animals could be seen moving, although many were hidden under the fluffy, cottony, almost silky material binding the margins and occupying some of the internal space. Although not 100% sure, several white critters that appeared on the decking after I shook the freshly fallen branchlet were I think from the same curled green leaves (there were quite a few just like this one, as shown in a 7yo child's hand). Images 11 to 14 were of one of the white creatures that were crawling slowly on the decking, after I placed it on my trousered thigh for clearer photos (with little advantage, due stark contrast and tiny size relative to the small gum leaf added for size comparison).
If the images turn out to be of two different taxa I'll resubmit separately!!
