Hopefully my post didn't come off too doom and gloom. My point is give it a shot and you may or may not like it. Everybody knows the pay and QOL sucks at any job(especially the regionals) when you first start, but until you are there you really can't decide if its what you want to do long term. Besides priorities change over time and that may be why sediment changes on why the career is worth it or not. I never understand why people come on and just spout off about "you knew what you were getting into". We all did. Sure everybody knows they love flying, but only you'll know for sure if you want the career for the long haul.
Now flying in Asia may be a little different. I know in Oz to fly for QF you need alot of time and those are jobs people hold onto life for. Its competitive there. You'll probably be flying in the bush for a while before you even get on with an Oz commuter. But someone who has actually done it would know better. I don't know jack about NZ so no comment. Asia usually wants high time if your going to Cathay. In China you might get hired as a low timer, but your only chances are probably if you are ethnic chinese and nationalized to get those jobs.
