Story in development – Australia's digital media exporters

Am working on a feature for B&T's Digital Media magazine on Australian digital media exporters to the US, and am trying to compile a comprehensive list of all that are out there. If anyone knows of one that should be included, please send me an email. I am looking for companies that have made a sale or set up an office in North America (or are just about to do so) and would class themselves as a digital media company (so for instance working in digital or mobile content and platforms).
