Schred your "CASA" license and forget Australia ( White Africa ). Come over here to the U.S. take the ATPL written study the red book for 2 days with a highlighter jump in the 777 simulator or the Boeing Sim at Gatwick do the type ride again ( Just the sim ride ). That gives you the FAA ATPL flight test, the written is already done and the oral will be over a coffee in the lunch room with your experience at the Sim.
Just put Australia behind you seriously the U.S. is FULL of Aussies who have moved over now working and AUS businesses transferred from Australia and places like Australia.
Life is short.
