It’s the final day of Crikey’s Man in the Hat competition. Today we publish the last of five photographs documenting highlight moments in the illustrious career of Brian Burke, the Zelig of Australian politics.

You’ll need to be one of the first five correct entries identifying the key figures and situations captured in each of the photographs received at [email protected] today after 3pm to be in the running to win one of five Panama hats supplied by Crikey’s new best friends at the supreme gentleman’s outfitters, Henry Bucks. Each hat is hand made in Ecuador and is a thing to treasure.

You’ll also need to tell us your hat size. The rest is between you and the Federal Cabinet.
