There is a flood of pilots over here in the UK that would love to return back to AUS but some are prevented from applying due to the minimum requirements. Take me for example.
4000 tt
1000 turboprop FO
1500 Airbus/737 FO
1500 Instrutor Time
I can't apply because of the requirement for 500 pic multiengine time, without going into the rights or wrongs of this I know that a lot of blokes over here in the UK are in a similar situation as myself because time to command at my current company is 10-15 years so will be unlikely to ever meet the minimum entry requirement. Tough luck really, just would'nt worry to much about the flood of expats.
