How many journalists does it take to get through 11.5 million documents about 214,000 companies that reveal how the world's rich use shell accounts to evade national regulations and taxes? Try 370, from more than 100 news organisations in 70 countries.

This morning's Panama Papers investigation -- based on a massive leaked trove of documents about the clients of Mossack Fonseca, a Panama law firm that sells shell companies to the world's wealthy -- is published in Australia by the ABC's Four Corners, Fairfax's Financial Review, and the Guardian Australia. It is the latest in a string of global investigations based on leaked documents co-ordinated through the Washington-based International Consortium of Investigative Journalists.
