My experience from living and working in australia is that the main blocker to people pirating stuff was stupidly expensive bandwidth fees - it the first time I've seen people (ok, nerds) going to a party with a hard drive and copying media from each other because your 20Gb a month didn't go that far. Last time I saw that in the UK was 10+ years ago.
The second, most important thing media producers can do to help stop piracy is just do simultaneous releases with the rest of the world. There were plenty of times that australian releases in the cinema were taking place the same time that DVD releases were happening in the rest of the world, TV is somewhat worse.
Do they even have Netflix yet? I heard some rumblings a few weeks ago about that.
