Skygal,
If your with REX already then you have an idea what the flying is like... It is another way to get into Qantas Mainline but it will take years to get in and in years to come it may not be the way. They do work you hard in the Sydney base and moral is on the low side with the newish management... My feelings are that the management dont take care of/support the staff as good as they should do in certain situations. Saying the above it is still good fun with the other crew and of course the flying experience! Make your choice and dont look back with regrets!
Good luck.
