Top here is Scoliidae, the scoliid wasp, are a family of about 560 species found worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Scoliid wasps act as important biocontrol agents, as many of the beetles they parasitize are pests.
The bottom critter is a European wasp, Vespula germanica (Hymenoptera: Vespidae). Although, as its name suggests, this critter is not native to Australia, it has become so widespread that it is now considered naturalised and no longer a notifiable pest in Victoria.
The native range of the European wasp is Europe, North Africa and temperate Asia, but it has since spread to North America, South America, South Africa, New Zealand, and Australia. Be careful of these. They can sting repeatedly and love crashing picnics!
