I've recently watched the first three episodes of the Australian TV series Satisfaction, but have to admit that I didn't really like it all too much. The Sex scenes are just like most boring soft porn, and the story-telling is too non-linear for my taste. Sometimes you don't know if you're in the present or past and what is going on. Always trying to find something optimistic about everything, I decided that it is probably good for training your listening comprehension of Australian [or maybe specifically Melbourne] English.
What is much more interesting and actually a lot of fun is Secret Diary of a Call Girl. Unfortunately each episode is really short, and every season is only 8 episodes. The main character (Belle/Hannah) appears very authentic. Very human, indeed. The kind of girl that I would adore for what she's doing ;)
