In my preparation for CeBIT starting tomorrow I found an article on the website about the recent export numbers for Australian Game Developers.
http://www.ausinnovate.com/2008/05/05/export-boom-for-game-makers/
The article mentions that 06-07 data shows $139.7 million in generated revenue, with most of the market coming from Queensland or Victoria. Programmers accounting for 29% of those employed, compared to 34% for artists. A logical number. :)
If you missed out on the free registration, check for information next year around February, that is the time the free Registration occurs.
