Hon DAVID PARKER: There's significant changes being made here. Already, bottom trawling is banned on all of the inner part of the gulf. There are extensions to some of the seining methods, and, as I've already explained, future bottom-trawling will be limited to corridors. Those will be chosen on the basis of minimising damage to benthic environments—in other words, protecting the most important benthic environments from bottom trawling. We think that this will make significant progress. It will also enable us, through the monitoring regime, to assess the longer-term outcomes of the sites relative to each other. If we've got limited corridors for bottom trawling, we will be able to carry out some in-depth science as to what is the effect of bottom trawling in the areas in which it remains compared with the environmental outcomes in other areas.
