Survival of a naive travel nurse.

I'm 25, and taking off on my first adventure overseas. Naive and unprepared only begins to describe me. This is my chance to get out on my own and see the world. I have some concerns though. I'm going alone, have no one coming to help navigate, and have no idea what's in store. Will Australia get the best of me or will I be able to become the seasoned traveler that I have always strived to become? Who knows, but it should be interesting if nothing else.
