I would also say to those who are cautious about this bill that it is relevant to look at what other countries do, not because we measure ourselves by them, and we certainly seek to lead them, but because it is of use in assessing what we're doing here today. So we and Australia are, at this stage, until this bill, hopefully, passes, the only people to give a minimum of 10 years' residence from the age of 20, when the maximum rate of super is payable immediately. If you look around the other countries whom we compare ourselves to, they tend to take a pro-rata basis, and they put things over a much longer period. So in Canada, you get a pro-rata basis of your super if you're an immigrant going over 40 years. It's 40 years' residence before you would be entitled to the full whack. In Denmark, it is, again, 40 years, I believe. In the UK, it is 35 years before you receive the maximum. There is something relevant in a country saying, "This is a mark of your contribution to society.", and I do not think it is immoral to make that point when it is all of us who are paying into this fund to recognise contributions, paid and unpaid, to our society. The contributions of parents who have taken time out of work, for example, are as valuable.
