So, they're only going after "webmasters", rather than the rest of us, who are purely passive consumers of information. That's an incredibly archaic thing for them to say, and it shows that they really don't get it.
There is no hard distinction between the people who make content online and the people who view it. If someone posts a comment on an Australian forum that links to Wikileaks, who gets fined? The person running the forum, who can't possibly police such things? The person who posted the link, who may be identified only by a username? Can Australia's policies deal with an indignant storm of linking to forbidden web sites? A thousand culprits, and not a webmaster to be found in the whole bunch!
The people writing the laws still think of the Internet as television 2.0, as a broadcast medium.
