Leave school, join a union and beoome a union official. Make sure you snuggle up to the most powerful faction. Become a union secretary. Or you could work for a leftie legal firm. Make sure you often have Chinese banquets with the faceless men.
Timely and cunning snuggling will allow you to be parachuted into a safe Labor seat early on. Or maybe straight into the Senate.
Be sure that you are on side the with the power brokers in the caucus so that you get a Cabinet post before too long.
Then you are well positioned to go straight to the top. There you can take up your destiny - Born to Rule Australia.
