Yeah and you will always be a cadet
remember most of the generations before have done hard bush time, PNG and the like and they had to really do it tough to get a break. Even if you didnt have to go North i still would, its like the annual migration, your right of passage, our Nirvana as a pah-lot.
Go north, its character building and lots of fun plus you will meet invaluable contacts in the industry that may be your leg up into the airline game if your an honest fellow!
