In the five years before a plan expires, the department completes a formal review to identify necessary alterations to the plan and deliver better outcomes for all water users, including the environment. This review is a requirement of section 43 of the Water Management Act 2000.

The Southern floodplain management plans have been reviewed. The Section 43 review report (including all submissions) will be used in conjunction with the Natural Resources Commission’s audit findings to inform the development of the new floodplain management plans.
