Have you considered the RAAF? They usually have engineering officer positions. Its not a bad life in the RAAF especially if your an officer. They also have some new kit coming so probably some good project work. Could get you through another door when your service tenure is complete. The problem (as you probably now realise) is that multiple Uni's pump out Aero's every year - but Australia doesn't have the demand - no industry.
All the best
