In terms of the issues that have been raised around that, we need to consider the affordability of superannuation. I would point members to the Retirement Commissioner's statement of earlier this year, which was reversing their position on raising the age for entitlement and saying that, actually, in the worst case scenarios of what percentage of GDP we would have to spend on superannuation, it's 7 percent—that's the worst case scenario. And that would be 7 percent of GDP by 2060, and that's actually a level that's in line with other countries right at the moment providing sustainable superannuation schemes. So I really would challenge that idea that it isn't sustainable at the levels of entitlement that we have at the moment, and I do think there are possibly more pressing issues to be looking at.
