I am planning to give myself a wonderful birthday present next year (but I will never say WHICH birthday, cough50cough) and thought I would take a great vacation. I've always wanted to visit Australia, but I need some tips from anyone that lives there or has visited. I will be on my own, is it easy to get around solo, or would I be better off with a tour? (I'd prefer to go solo, if it is manageable) When is the best time to go? What shouldn't I miss? And will I be able to see kangaroos and koalas?
