Labor believes that there can be benefits from change, but if we're going to have change, it needs to be on the basis that the government has addressed the cost benefit issues, and has addressed the legitimate privacy concerns of Australians.

In relation to cost benefit, it claims there will be saving of the order of 3 billion dollars over ten years, but it refuses to release the assumption on which that claim is based, so it simply expects Australians to take it on trust.
