(e) there are important and significant environmental assets that are associated with the Basin water resources and that need protection; and

(i) the availability of the Basin water resources; and
(ii) the health of the Basin water resources or the environmental assets associated with the Basin water resources; and
(g) the inefficient and/or inappropriate use of the Basin water resources would have a significant detrimental economic and social impact on the wellbeing of the communities in the Murray - Darling Basin; and
