to somebody the other day recognising that South Australia put some caps in place back in the 1960s. So they're all important steps along the way. I don't want my part of the history of the management of the Murray-Darling system to be seen as the one unique thing that's ever happened. We're just one more step along the pathway. But the pathway's important. What I'm saying is whatever the numbers that I put out in the Guide at the start -- and we have working around this 2800 figure for the purposes of modelling -- that's the start of the conversation, it's not the finish. This is where I want people to be given the opportunity to have a chance to have a real say over that 7-year period to allow new knowledge to adapt that number. And there's a few ways that that needs to be approached. First of all, we're currently working plus or minus 400GL of that to see what 2400GL looks like and what 2800GL looks like. In addition, we're modelling to see just how much water we can send down the system given the constraints. People have built on floodplains -- we've done that deliberately, we've got natural constraints in the system -- the chokes and all those sorts of things that mean that we have to be very clear that what we actually send down can be delivered in terms of providing environmental benefit but also not causing damage along the way.
