Anyone interested in political activism may want to sign up to the Libertarian Leadership School run by the American Libertarian Party. They run 6-week online correspondence courses in the same manner as you’d expect from a professional educational institution. It costs $50 ($55 Australian) per course.
If you’re interested in being a politician this is a good way to learn something and support the broader libertarian movement at the same time.
As I haven’t done any of the subjects, I’m not sure how much is America-specific and how much could be applied in Australia. But it’d be easy enough to find out before enrolling.
