Anybody have an idea of what this is? My first thought was Boxthorn but leaves are different. Shrub has been heavily browsed by livestock and is covered in lichen. Getting what looks like buds coming on it now.
An almost cylindrical gall with a slightly broader base (point of attachment to the stem). The gall appeared woody with a rough exterior. A drier gall seen on the same tree appeared to have annular splits.
The apical end of the gall had rounded edges with a depressed centre and perfectly circular hole.
Spotted on ? Eucalyptus blakelyi (Blakely's red gum) in the Weddin Mountains National Park, NSW.

These were small slightly flattened trumpet-shaped lerps spotted on eucalyptus leaves. The broader part of these lerps were transparent and appeared fragile. Each of these lerps appeared to have a nymph inside with their pale orange bodies clearly visible through the transparent lerp shell.
Unlike lerps of Glycaspis species, I could not see any ants crawling around these lerps. I assume therefore that these lerps are not made of the same material as the Glycaspis species. Also, this species of Creiis lerps seemed keratinous. Various birds feed on lerps but a study on lerp-feeding by birds suggests that birds avoided the Creiis species of lerps.
