You are going to need money to emigrate. Look at the thread on "How much did you bring with you" and some others on the cost of living, to start with. Look at some of the web sites that are mentioned for jobs, and see what the pay will be. Look at domain.com to see some rents (remember that those nice low numbers are per week), and browse around the Australian portion of gumtree.com. That will give you some idea of what the situation woul be like for you.

As far as whether you would be happy emigrating, I don't know. You could try for a working holiday visa to New Zealand, to try out living abroad.
