Anyone emigrated from the UK to Australia?

Hiya I'm currently a mental health nursing student in the UK (london) and I will be qualified in 3 years time. Moving to & working in Australia has always been a dream of mine & I'm determined to make that happen. I was just wondering how do I go about it? Anyone who has done this whether as a nurse or another occupation? I know its early but 3 years goes by quick & its good to start looking into these things, I have looked online but require additional info. Oh I also have a child who will be 11 years once I qualify just in time to start high school and I'm interested in moving to Melbourne or Perth, Sidney is another option.
