G'day shiver, first you need to look at the
dept of immigration site to see if you qualify for a visa to allow you to live and work in Australia.
Actually, this
section is probably a better place to start.
Then have a look at the
CASA site for the conversion and other bits and pieces.
Please note
As of 1 November 2005 the Department of Immigration and Citizenship have removed aircraft pilots from the Skilled Occupation List.
Therefore, the Civil Aviation Safety Authority no longer issues skills assessments for the purpose General Skilled Migration.
this from the CASA site. However, I would cross reference this info with what the Dept of Immigration says.
In Europe, a CPL holder is probably going to start in a turboprop or possibly a jet. Others instruct and so on. In Australia, it is very rare to go straight onto turbine equipment unless you're part of a cadet scheme with that airline.
Also, your ATPL subjects will not be formally recognised, you'll have to do the Australian ATPL subjects to get an ATPL. However, there's no rush for that.
