The member asked for the cost of back-pay. The estimates I've received for that are anywhere between $660 million and $1 billion. I think part of the thing that we're conscious of is that if there has to be a two-year back-pay for nurses, then it's likely that other parts of the health sector and possibly parts of the State sector—but certainly the health sector—will be wanting to seek that. I can report to the committee that in relation to the midwives' pay equity claim, there have been substantial negotiations and they've pretty much reached the point where the last remaining aspect of that is a lump sum payment, and the midwives have made it clear that they wish to hold off until they see what happens with whether or not the registered nurses will get their two-year back-pay claim.
