I have flown with just one Malaysian F/O who lives in JB. No expat to my knowledge lives in JB. It is a bit of a dump in my opinion. I have been over there twice and that was enough although those who play Golf find it worthwhile going over.
Pin Head You would be mad to even consider trying to commute from Sydney. Yes a few do from Perth and most have unlimited ID 90's You if SQ Cargo would get none and only 4 pa if Mainline which on B777 would make for an interesting lifestyle.
Sydney Flights are always Full and you would have a nervous breakdown in no time at all trying to get on sub load and being at the very bottom of a long list being a new joiner.
Roster requests to help you commute??? Ha Ha.Ha This is Asia
