Thank you Danilo Lüdke for identifying and Won-Gun Kim for helping with the id of this species for us

General Species Information:
Found in the Adelaide Hills and possibly elsewhere
A mainly green bug, ~8.5mm long.
Notice the lack of any horns protruding from the sides of the pronotum. Small horns would indicate C. simplex
Like the Long-spined Shield Bug, this species has a keel, but is not as noticeable. You can just see it in the profile shot. The ventral shot shows the shorter proboscis & little evidence of the keel.
Originally thought to be Cuspicona simplex, then C. eremophilae, then Cuspicona privata, Ocirrhoe prasinata. As you can see, difficult to separate.
Won-Gun also said "the shapes of the posterolateral pronotal margin, the scutellum, etc. For example, the posterolateral margin is relatively straight and relatively horizontal in C. privata when compared with O. prasinata. In addition, the dorsal surface of this bug is much closer to C. simplex than the species of the genus Ocirrhoe."
Notice that the wings are almost clear, and the edges of the abdomen have small black tipped spines on the edges of the "laterotergites" (abdominal segments). Danilo said "The laminate anterolateral margin of the pronotum is continuing onto the region of the humeral angle, which explicitely mentioned by Gross separates O. prasinata and allies from the C. thoracica group including C. privata. Also the basal scutellal foveae are visible here."
After exploding the images up, and adding more of the same specimen Danilo downgraded the id saying "From the pygophore we can at least clearly say that this is NOT Ocirrhoe prasinata." A case of needing the specimen under a microscope to differentiate.
Of course it's always possible it's undescribed.
