Four key corroborating features: 1. the lack of dorsal extension of the yellow patches on abdominal segments 7 and 8; 2. the inverted black "T" mark on the frons (there would be a metallic black patch on the upper frons for an Australian Emerald); 3. the brown upper part of the eyes (rather than blueish/greeninsh); and 4. the yellow pterostigma in this young individual (darker in australiae). Your photos are excellent for showing all of these features.
