I think they are tiny wasps. Possibly Family Scelionidae, subfamily Telenominae. I have a couple of them in a test tube in my fridge but I don't dare take them out for a better photo because I worry they will fly away. Any advice?
@KimberiRP I have just added 4 photos of one of the frozen wasps that I took at home with my MPE65 lens. It was very hard. The whole house is shaking when you look at something that close ;-)
@kasiaaus I think you are right about the family: Scelionidae. I can't suggest a subfamily, might be either Scelioninae or Telenominae; the former has over 500 Australian species and the latter nearly 100, and that's just the ones that are named. https://tasmanianinsectfieldguide.com/hexapoda/insectsoftasmaniahymenoptera2/superfamily-platygastroidea/scelionidae/
