Hon DAVID PARKER: The payment is made on the basis of the automated data sets. We encourage people who think that they are not eligible to pay it back, but they're not obliged to pay it back because it's been legitimately paid to them. The cost of the alternative, which would have been an application-based process, would have been more than the cost savings made through that process and, as I said, wouldn't have got the payment out to the 1.3 million people who've already received it.
