Meet Australia's jet-setting economist

This weekend the financial world will be focused on Sydney where the G20 summit is being held.

One man who will be keeping a close eye on proceedings is Tim Harcourt.

He's an Australian economist but spends his life visiting and analysing virtually every economy all over the world.

He says the isolation that once defined Australia isn't nearly as relevant as it once was, and the country is turning from "Down Under" to "Down Wonder".
