I guess I would say there are a couple of differences here. First of all, the review agencies all have a complaints function as part of their framework, and they operate in a quasi-judicial frame. They're a slightly different creature, if you will.
Also, what's trying to be achieved here in terms of this proposal is something that's fundamentally different, I would argue, in a couple of ways. First of all, the design is to give parliamentarians direct access to information on national security matters, and to do so in a way that's right across government.
You referenced the review agencies. Obviously, they operate in three particular spheres. What this committee does is give a broader frame in terms of being able to pursue national security and intelligence matters right across the board.
