Senator CORMANN (Western Australia—Leader of the Government in the Senate, Minister for Finance, Special Minister of State and Vice-President of the Executive Council) (14:39): I thank Senator Hanson for the question. The first point I would make is that generations and generations of migrants to Australia, coming from all corners of the world—whether it's Greece, like the family of our valued colleague Senator Georgiou, or Belgium, like me, or Kenya, like Senator Gichuhi, or anywhere else—have made fantastic contributions to our country. The country we are today in large part is due to the contribution made by them, and we are a better country because of it. The next point I would make is that Australia, like many other Western countries, has an ageing population. Having an ageing population is a drag on economic growth. Being able to attract, in particular, young, talented migrants to Australia from all around the word, with an attitude of wanting to help our country be even better, is good for our economy. The PRESIDENT: Senator Hanson, on a point of order? Senator Hanson: I agree with the minister's answer so far, but my question is: how much in GDP does immigration contribute? The PRESIDENT: The minister has been speaking for just over a minute. I'm listening carefully and I note he has 52 seconds to complete his answer. You've taken the chance to remind him of the question, Senator Hanson. Senator CORMANN: I was making a general point that I thought was important. In terms of the specific question, I will ask the Treasurer whether he has anything else to add to it. But let me make the point again: Australia is what it is today in large part because of the economic and social contribution of generations of migrants to Australia. We are a better country because people from around the world have made the decision to make Australia their home, and I think we should value and recognise that. I will check with the Treasurer whether he's got anything further to add. The PRESIDENT: Senator Hanson, a supplementary question.
