Immigration Controls

I am grateful to the hon. Gentleman for raising that point. That is not the experience in Australia. What happens there is similar to our own arrangements under any other work permit. After a certain period working in the economy, migrants are entitled to apply for citizenship. The hon. Gentleman is right that at that point they can move anywhere in the area, but the experience of Australia is that they do not. They have put down roots and stay where they have settled. That has had the desired effect of contributing to population growth in those areas.
