I want to work and live in Australia?

[Ozmaniac]

You can't work in Australia unless you have a work visa and you have zero chance of getting a work visa unless you have formal qualifications and experience in an occupation on the Consolidated Skilled Occupation List (CSOL) and employer sponsorship. From what you've written (you haven't mentioned a degree or any other formal qualifications), you would not be eligible for any work visa so you're wasting your time applying for jobs in Australia - no employer would be allowed to sponsor you.
