Okay. That's helpful.
I think a lot of countries around the world have gone to some sort of biometric screening. The real issue that concerns me there is what we do with that data once we get it.
I think Canada has done an excellent job of reducing its clandestine population. The figures are absolutely striking at how low the illegal population is in Canada compared to Europe, the United States, and even in some.... It's not the same in Australia.
Largely we've achieved this through having a refugee system that encourages people to identify themselves to the state. The fingerprinting, the photographing of people coming over the border, which is currently done for many—you will have seen it going into the United States—is a big resource strain for a very small yield.
So I think resourcing our intelligence agencies so that we know who we're looking for is probably a better use of scarce dollars.
