Para ops or meat bombing as it is affectionately known in Oz is a fairly popular way of gaining those first couple of hundred hours.
You need a CPL unfortunately there are many unscupulous
commercial para operations that don't pay or underpay.
To convert a JAR CPL or fATPL to an Oz CPL isn't too difficult or costly. Unfortunately the hardest part will be getting the right to work visa.
Best check the
CASA website for more info re the lic.
Check the
Immigration to Oz website. Has all sorts of info on visa's etc.
