Interesting piece of editing, if you ask me. It actually have been aware of Australian media's allergy to anything non-white. I used to live with a chick that had Indigenous, Torres, Pacific Island lineage. Her nieces and nephews used to come around on occasion and plonk themselves in front of the box. Interestingly enough, there's NO mainstream tele aimed at non-Caucasians.
I really don't have an opinion, but I'm sure someone will read this that has a better idea than me of why this is the case. Next time you're watching mainstream tele take note of what cultures feature in Australian made media. Judge for yourself.
