Hi tail whell, may you please explain this part more clearly?
Conversion of a Working Holiday Visa to an Australian Permanent Residence Visa is certainly not guaranteed, particularly for pilots and may even be impossible. Your chances would be enhanced if you also held other vocational skills on the Skills in Demand List or had some entitlement to Australian residence.
I knew that normally to be sponsored by an employer an overseas doesn't need to do more thing than just go to an immigrand agent (who is optional as far as I know) to assist him with all the burocratic stuff, and the employer has to guarantee a minimum amount salary.
