Slashdot has an item on Australian TV and BitTorrent - i.e., some viewers there would like to have it (given that many popular shows air in the US months before they show up in Oz) - the local tv networks are far less sanguine about the idea. I've run into this problem myself on this blog - back when "Angel" was nearing the end of its run, I had a few readers ask me not to post any details - since the show wouldn't be ending "down under" for months.
This is yet another example of time and distance compression being wrought by the net. Even a decade ago, you weren't likely to hear tv/movie details casually when something aired earlier in another region. Now, you have to go out of your way not to hear such things. I suspect that we are getting closer and closer to synchronized world-wide releases. It's already happening with movies - tv is going to be forced to follow.
