The WikiLeaks website is fast gaining credibility as a whistleblowing site for political secrets, but one of the people behind it, Australian Julian Assange, remains an international man of mystery.
His biggest coup so far has been obtaining classified video of Iraqi civilians and Reuters staff being gunned down by a US military helicopter, dubbed Collateral Murder, which has been watched over six million times.
The site also released what it claimed was the list of websites to be banned under the Australian Government's proposed internet filter, before parts of WikiLeaks itself were blacklisted by the Australian Communications and Media Authority.
But Julian Assange does all this with no home or office, constantly travelling the world, so Mark Davis tracked him down to Norway, followed him to Sweden, where many of WikiLeaks servers are based, then to Iceland, where he was advising politicians on turning the country into a safe haven for whistleblowers, and finally to Australia, where he was told his passport would be cancelled amid WikiLeaks being investigated by the Australian Federal Police.
So what did he manage to find out about this shy former-computer-hacker-turned-investigative-journalist?
The chat ran from 9.30pm-10.30pm AEST, so apologies to viewers of later showings, but Julian and Mark were only available online for a limited time. Anyone who missed the chat can replay it below.
