You mean they've played some in Canberra? Here in Sydney we've been teased with it for the last 2 years but not one episode has been played - not even over two non-rating seasons.
They haven't played this in Canberra that I'm aware but since I had the DVD of S1, I mentioned it to a friend in Melbourne. She said that a couple of episodes had been played there.
I very rarely watch any broadcast TV anymore and hence I don't see the guides or promos. I prefer to dip my toe into various programs via the season sets on DVD.
