So, you’re a television journalist working in Australia, and finally your big break arrives - a posting as the main correspondent in another country, say in Asia, maybe the Middle East. But you don’t speak the language, and and you don't know the intricacies of culture or georgraphy. And you want to dig out those really important stories, the ones that could be critical but aren’t in obvious places. So, to use the refrain from that 80’s pop song – “who ya gonna call?”Colleen Murrell, associate professor of journalism at Swinburne University, with a background in television journalism in many countries around the world, and a book entitled ‘Foreign Correspondents and International Newsgathering: The Role of Fixers’ is well placed to answer that question in this week's edition of Communication Mixdown.
