He most certianly isn't. Scott Ludlam is from the Greens party, which are a not-extreme-but-still-left left-wing party. They're the 3rd 'major' party in AU politics, but trail far behind the big two. The big two came together on this to pass it, so although many of the minor parties are up in arms about it, it got steamrolled through.
Additionally, Scott Ludlam is far more technologically adept than many of the old white law-educated guys in parliament. He's younger, he's very much of the IT era and is much more understanding of technology as a result. That's why he speaks out against this and other technology-related policies so often, because he gets the technological side of things.
