Hon DAVID PARKER: The biophysical limits are intended to cover all of the domains such as water and air quality, and indigenous biodiversity. The Randerson report upon which the legislation is based recommends that the gaps in those are filled in, that national direction is consolidated, and that that consolidation resolves some of the internal contradictions between different national direction, and so there's more certainty in the system, which will in itself enable clearer investment signals to the private sector as to where development should proceed more quickly.
