Public ownership and a small audit of Australia Post

In passing through a country town recently I thought about who actually owns Australia Post. As it turns out, I have a small share. As does every other Australian citizen, as it's a public company. It's a wonderful business, providing a solid postal delivery service and employing many Australians.
In 2002 , Australia Post made a declared Profit of $297 million. So I'm thinking as a minor shareholder - actually, equal shareholder to everyone else who's an Australian citizen - I should be able to find out how much Australia Post makes and where exactly that money goes. So over the next few months you will be able to trace my progress in chasing the money trail - and hopefully not chasing my tail! :-)
