I've got the whole series of it on I don't know how many discs. I bought them off an Australian eBay seller a while ago. I've not watched them yet, but I will when I'm in the mood to. Brilliant series/soap.
Edit: The best thing about Prisoner Cell Block H was that it wasn't at all realistic, which meant that you could sit on the couch/chair in comfort and watch it. Okay, there were a few uncomfortable finales, but the majority of the storylines were just fun to watch.
