Tinpis4,
Dude, the requirements for those airlines you mentioned are quite high, and pretty hard to get into...even after you have been flying for a while. Completing flying school is the easy bit, afterwards is where you have to be prepared to move countries, sacrifice holidays and work for around nothing just for the love of flying to gain those hours of experience you need to even apply to the likes of
VB, Jet*, Rex..and so on...
Either the Cadetship route with Qantas, Instructor rating or like most of us...the regional Charter company either in a different country or in the middle of no-where is what happens in reality after flying school.
What ever you choose, Good Luck! Also, those airlines you mentioned can be found on the internet with their min. requirments and current positions....Just search for it, I am sure you will find it.
Anyway, Good Luck with that..
