(4)  For the purposes of a report under subsection (3):
(a)  the Natural Resources Commission is to call for public submissions and to have regard to any duly received, and
(b)  the Natural Resources Commission is to have regard to any other relevant State-wide and regional government policies or agreements that apply to the catchment management area.

(a)  the purpose of the reduction to water allocations is to restore water to the environment because of natural reductions in inflow to the relevant water source, including but not limited to changes resulting from climate change, drought or bushfires, or
(b)  the purpose of the reduction to water allocations is to provide additional water to the environment because of more accurate scientific knowledge that demonstrates that the amount previously allocated to the environment is inadequate, but not if that purpose is also the purpose referred to in paragraph (d), or
