I agree... I'm Australian and can't access any of them, and even some things on YouTube come up with a message telling me "This content can't be viewed in your country".
If we had access to these sites, and/or they brought shows out on TV here within a few days of the US release, then there would be a many times less unauthorised viewing. A good example of how bad it can be is NBC's Chuck, which is a great show. The fourth season just ended a couple of weeks ago in the US - but as far as I know not one episode has been on free-to-air here. They did start showing the first season of it on cable about when the third season aired in the US (about a year and a half late) if I remember correctly...
