Book excerpt: The Prime Minister's job is to make our country as good as it can be. But every Prime Minister Australia has ever had has been a grown-up! What if the grown-ups weren't in charge? What would kids do if they ran the country? We could have submarines to scoop garbage out of the sea ... or teach koalas how to do karate ... and hang giant rainbows in the sky to make everyone happy. What would YOU do if you were Prime Minster?
